If Peter and Mia were 10 feet apart when they saw crumb falling, then the crumb fall at a distance of 8/3 feet from Peter.

The Distance between Peter and Mia when the crumb fell is 10 feet,

The speed at which Peter ran is = 1 foot per second,

The speed at which Mia ran is = 2 feet per second,

We know that, Mia started running 1 second after Peter,

Let us denote the time it took for both Peter and Mia to reach the crumb as 't' seconds.

Since both Peter and Mia started from the same point, the distances they covered are equal to the speed multiplied by time.

So, Distance covered by Peter = Peter's speed × t = 1×t = t feet,

Distance covered by Mia = Mia's speed × (t + 1) = 2×(t + 1) = 2t + 2 feet;

The Distance covered by Peter + Distance covered by Mia = Distance between Peter and Mia when the crumb fell,

⇒ t + 2t + 2 = 10,

⇒ 3t + 2 = 10,

⇒ 3t = 10 - 2,

⇒ 3t = 8,

⇒ t = 8/3,

So, it took 8/3 seconds for both Peter and Mia to reach the crumb.

Now, we calculate the distance from Peter where the crumb fell on the ground.

Distance from Peter = (Peter's speed)×(time taken by Peter to reach the crumb)

⇒ 1 × (8/3) = 8/3 feet,

Therefore, the crumb fell on the ground approximately 8/3 feet away from Peter.

The gradient of the curve when t = 3 is dy/dx = 6/3700.

First, let's find the expressions for dy/dt and dx/dt using the given parametric equations:
Differentiate x with respect to t:
[tex]x = t(t^2 + 1)^3[/tex]
[tex]dx/dt = (t^2 + 1)^3 + 3t^2(t^2 + 1)^2[/tex]
Differentiate y with respect to t:
[tex]y = t^2 + 1[/tex]
dy/dt = 2t
Now that we have dy/dt and dx/dt, we can find dy/dx:
Divide dy/dt by dx/dt to get dy/dx:
[tex]dy/dx = (2t) / [(t^2 + 1)^3 + 3t^2(t^2 + 1)^2][/tex]
Find the gradient of the curve when t = 3 by substituting t = 3 into the dy/dx expression:
[tex]dy/dx = (2 * 3) / [(3^2 + 1)^3 + 3 * 3^2 * (3^2 + 1)^2][/tex]
[tex]dy/dx = 6 / [(9 + 1)^3 + 3 * 9 * (9 + 1)^2][/tex]
[tex]dy/dx = 6 / [10^3 + 27 * 10^2][/tex]
dy/dx = 6 / [1000 + 2700]
dy/dx = 6 / 3700.

The inverse Laplace transformation of F(s)=-3s-8/s²+3s+2 is [tex]f(t)=-3e^{-t}+7e^{2t}[/tex].

Given that, F(s)=-3s-8/s²+3s+2.

To solve this problem, we need to use the inverse Laplace transform formula. The formula for the inverse Laplace transform of a function F(s) is given by:

f(t) = [tex]\frac{1}{2\pi } \int\limits {F(s)\times e^{st}} \, ds[/tex]

In this problem, we are given the function F(s)=-3s-8/s²+3s+2. Substituting this in the formula, we get:

f(t) = [tex]\frac{1}{2\pi } \int\limits {-3s-\frac{8}{s^2+3s+2e^{st}} } \, ds[/tex]

We can solve this integral using the partial fraction decomposition method. We need to factorize the denominator, s²-3s-2.

The factors of s²-3s-2 are (s+2)(s-1).

Now we can decompose the expression as:

-3s-8/(s²+3s+2) = -3s+3/[(s+2)(s-1)]

We can further decompose this expression as:

-3s+3/[(s+2)(s-1)] = A/s+2 + B/s-1

where A and B are constants.

We can find the values of A and B by equating the numerators and denominators of the left and right hand side of equation.

For s=-2, we get:

-3(-2)+3 = A(-2)+B(-1)

Solving for A and B, we get A=7 and B=-3

Therefore, the expression becomes:

-3s-8/(s²+3s+2) = -3/s-1 + 7/s+2

Substituting this expression in the inverse Laplace transform formula, we get

f(t) = [tex]-\frac{3}{2\pi} \int\limits {e^{st}} \, \frac{ds}{s-1}+\frac{7}{2\pi } \int\limits {e^{st}} \, \frac{ds}{s+2}[/tex]

Integrating both the terms of the above equation, we get [tex]f(t)=-3e^{-t}+7e^{2t}[/tex].

Therefore, the inverse Laplace transformation of F(s)=-3s-8/s²+3s+2 is [tex]f(t)=-3e^{-t}+7e^{2t}[/tex].

It will take about 4.81 hours for the number of bacteria to triple.

Since the rate of increase of bacteria is proportional to the number present, we can write:

dN/dt = k*N,

where N is the number of bacteria,

t is time,

and k is the proportionality constant.

To solve for k, we can use the given information that the number of bacteria doubles in 3 hours.

Let N0 be the initial number of bacteria, then after 3 hours we have:

N(3) = 2*N0

Using the solution to the differential equation above, we have:

N(3) = N0exp(k3)

Substituting in the value of N(3) above, we get:

2N0 = N0exp(k*3)

To simplify, we have:

k = ln(2)/3

Now we can use this value of k to find the time it takes for the number of bacteria to triple.

Let T be the time it takes for the number of bacteria to triple, then we have:

N(T) = 3*N0

Using the solution to the differential equation above, we have:

N(T) = N0exp(kT)

Substituting in the value of k above, we get:

N(T) = N0*exp(ln(2)*T/3)

To simplify, we have:

T = (3/ln(2))*ln(3)

Using a calculator, we get:

Answer:

First, let's find the cost of the DVR recorder. Martha paid a total of $288.60 for the recorder and 8 months of service. Since the service costs $19.95 per month, the total cost of 8 months of service is 8 * $19.95 = $159.60. Subtracting this from the total amount Martha paid, we get $288.60 - $159.60 = $129 for the cost of the DVR recorder.

Now, let’s find the total amount Martha will have paid for the 2-year agreement she signed. A 2-year agreement is equivalent to 24 months. So, the total cost of service for 24 months is 24 * $19.95 = $478.80. Adding this to the cost of the DVR recorder, we get $478.80 + $129 = $607.80 as the total amount Martha will have paid for the 2-year agreement she signed.

Step-by-step explanation:

The equation of the tangent to the circle at P is y = (1/3)x – 6

What is equation of the circle?

The standard equation of a circle is:

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle and r is the radius.

To work out the equation of the tangent to the circle at P, we need to use the fact that the tangent to a circle is perpendicular to the radius at the point of tangency.

Since P has x-coordinate 3 and is below the x-axis, its y-coordinate is given by:

y = -√(90 - x²) (taking the negative square root because P is below the x-axis)

So the coordinates of P are (3, -√(90 - 3²)) = (3, -9).

To find the equation of the radius OP, we can use the fact that O is the center of the circle and OP is a radius, so its equation is:

y - y₁ = m(x - x₁), where m is the gradient of OP.

The center of the circle is at the origin (0, 0), so the coordinates of O are (0, 0).

The coordinates of P are (3, -9), so the gradient of OP is:

m = (y - y₁)/(x - x₁) = (-9 - 0)/(3 - 0) = -3

Therefore, the equation of OP is:

y - 0 = -3(x - 0)

y = -3x

Since the tangent is perpendicular to the radius at P, its gradient is the negative reciprocal of the gradient of OP at P.

The gradient of OP at P is the same as the gradient of the tangent at P, which is:

m = -1/(-3) = 1/3

Therefore, the equation of the tangent to the circle at P is:

y - (-9) = (1/3)(x - 3)

y = (1/3)x – 6

The correct option is: "as the df increases, the t-distribution becomes more normal."

The t-distribution is a family of distributions that depend on a parameter called degrees of freedom (df). The t-distribution is similar to the normal distribution in shape but has heavier tails. As the degrees of freedom increase, the t-distribution becomes more normal in shape and its tails become less heavy.

Therefore, the statements "they are unimodal and symmetric" and "they have fatter tails than a normal distribution" are not entirely accurate. While the t-distribution can be roughly symmetrical and unimodal, its shape depends on the degrees of freedom and can vary from sample to sample. Additionally, the t-distribution has fatter tails than a normal distribution only for small sample sizes and approaches a normal distribution as the sample size (degrees of freedom) increases.

Approximately 188 values ​​fall within 2 standard deviations of the mean when 280 sociology students take an exam and the distribution of their scores can be treated as normal.

It states that the grade distribution of 280 sociology students can be considered normal. Let μ be the average score of the students and σ be the standard deviation.

A run appear of thumb is that nearly 68% of the comes almost are interior 1 standard deviation of the pitiless, nearly 95% of the comes around are interior 2 standard deviations of the brutal, and nearly 99.7% of the comes approximately are interior 3 standard deviations of the cruel. 

Since we are interested in finding the number of values ​​within 2 standard deviations of the mean, we can estimate this using a rule of thumb.

We know that about 95% of the results are within 2 standard deviations of the mean. So you can write:

P(μ - 2σ < X < μ + 2σ) = 0.95

where X is the student's score.

We can simplify this expression by subtracting μ from both sides.

P(-2σ < X - μ < 2σ) = 0.95

Now we can find the probability that the standard normal variable Z falls between -2 and 2 using the standard normal distribution. we have:

P(-2 < Z < 2) = 0.95

Using a standard normal distribution table or a calculator capable of calculating the normal probability, we can find that the probability that Z is between -2 and 2 is approximately 0.9545.

So it looks like this:

P(-2 < Z < 2) = P((X - μ)/σ < 2) - P((X - μ)/σ < -2) = 0.9545

Using a standard normal distribution table or a calculator capable of calculating the inverse normal probability, we find that a value of 2 in the standard normal distribution corresponds to a z-score of approximately 1.96.

So it looks like this:

P((X - μ)/σ < 1.96) - P((X - μ)/σ < -1.96) = 0.9545

Since the distribution of values ​​is normal, we know that the standard normal variable (X - μ)/σ follows the standard normal distribution. Therefore, you can find the z-score corresponding to 1.96 using a standard normal distribution table or a calculator capable of calculating the inverse normal probability.

A z-score equal to 1.96 is found to be approximately 0.975.

So it looks like this:

P(Z < 0.975) - P(Z < -0.975) = 0.9545

Using a standard normal distribution table or a calculator capable of calculating normal probabilities, we find:

P(Z < 0.975) = 0.8365 and P(Z < -0.975) = 0.1635

So it looks like this:

0.8365 - 0.1635 = 0.673

Subsequently, roughly 67.3% of the comes about are inside 2 standard deviations of the mean.

To discover the number of comes about that are inside two standard deviations of the cruel, we have to increase that rate by the entire number of understudies.

 Number of outcomes within 2 standard deviations of the mean = 0.673 × 280 ≈ 188

Therefore, approximately 188 values ​​fall within 2 standard deviations of the mean.

The exact value of cos(ecos⁻¹(-0.2) + sin(-2)) is calculated to be (cos(1))(cos(2)).

The expression cos⁻¹(-) means the inverse cosine of a negative value, but since the range of the inverse cosine function is restricted to [0,π], there is no real number whose cosine is -1. Therefore, this expression is undefined.

Assuming that the expression was intended to be cos⁻¹(-0.2) instead of cos⁻¹(-), we can proceed as follows:

cos(ecos⁻¹(-0.2) + sin(-2))

We know that cos(ecos⁻¹(x)) = x/|x| when x is not equal to zero, so we can apply this formula to simplify the expression:

cos(ecos⁻¹(-0.2)) = -0.2/|-0.2| = -1

Now we have:

cos(-1 + sin(-2))

The sine of any angle is between -1 and 1, so sin(-2) is between -1 and 1. Therefore, cos(-1 + sin(-2)) is a valid expression and we can evaluate it using the sum formula for cosine:

cos(-1 + sin(-2)) = cos(-1)cos(sin(-2)) - sin(-1)sin(sin(-2))

= cos(1)cos(-2) - 0sin(-2)

= cos(1)cos(2)

= (cos(1))(cos(2))

a. (df)(s^2): This component represents the sum of squares due to the effect of the independent variable, also known as the factor or treatment. It is calculated by multiplying the degrees of freedom (df), which is the number of levels of the factor minus one, by the variance of the data within each level (s^2). This component quantifies the amount of variation in the dependent variable that can be explained by the independent variable.

b. (df)(s): This component represents the sum of squares due to the interaction between the independent variable and other factors, also known as the interaction effect. It is calculated by multiplying the degrees of freedom (df) by the standard deviation (s) of the data. This component quantifies the amount of variation in the dependent variable that is due to the joint effect of the independent variable and other factors.

c. (n)(s^2): This component represents the sum of squares due to the variation within groups, also known as the error or residual sum of squares. It is calculated by multiplying the sample size (n) by the variance of the data within each group (s^2). This component quantifies the amount of variation in the dependent variable that is not explained by the independent variable or other factors.

The probability that X is less than or equal to 48 is approximately 0.023.

To use the normal approximation, we first need to check if the conditions are met:

1. The sample size is large enough: n*p = 93*0.48 = 44.64 and n*(1-p) = 93*0.52 = 48.36, both greater than 10.

2. The observations are independent: we assume that the sample is random and that the sample size is less than 10% of the population size.

Given these conditions, we can use the normal distribution to approximate the binomial distribution.

We standardize X using the formula:

z = [tex](X - n*p) / \sqrt{(n*p*(1-p)) }[/tex]

Substituting the values, we get:

z = (48 - 93*0.48) / sqrt(93*0.48*0.52) = -1.99

Using a standard normal distribution table or calculator, we can find the probability:

Using a standard normal distribution table, find the z-score corresponding to an area of 0.9800 (98%). The closest value on the table is 0.9798, which corresponds to a z-score of 2.05.

Step 2: Calculate the temperature reading corresponding to the 98th percentile.

Step 3: Determine which graph represents P98.
The correct graph should have a normal distribution curve, with the mean at 0°C and the shaded area under the curve covering 98% of the area to the left of the P98 value (205°C). Look for the graph that represents these conditions.

The answer is: The temperature reading corresponding to the 98th percentile is 205°C. To find the correct graph, look for a normal distribution curve with a mean of 0°C and a shaded area covering 98% of the curve to the left of 205°.

IN a triangle HIJ , the length of the side j opposite to angle J using given measurements is equal to 3504.5 cm ( nearest tenth of a centimeter ).

In a triangle HIJ,

h = 340 cm,

m ∠J = 116°

and m ∠H =5°

Use the Law of Sines to solve for the length of side JH.

The Law of Sines states that,

h /sin H = i/sin I = j/sin J

where h, i, and j are the side lengths of a triangle and H, I, and J are the angles opposite those sides.

h/sin H = j/sin J

Plugging in the known values,

340/sin 5° = j/sin 116°

Solving for j,

⇒ j = (340 × sin 116°) / sin 5°

⇒  j = 340 × 0.89879 / 0.0872

⇒ j ≈ 3504.5 cm

Therefore, the length of j in triangle HIJ is approximately 3504.5 cm to the nearest 10th of a centimeter.

The equation of the oblique asymptote of the average cost function C(x) is y = 0.02x + 92.

To find the oblique asymptote of the average cost function C(x), we first need to find the formula for the average cost function.
The formula for the average cost function is C(x)/x.
Substituting the given cost function C(x) into this formula, we get:
C(x)/x = (15,000 + 92x + 0.02x^2)/x
Next, we need to find the limit of this expression as x approaches infinity.
We can use long division or synthetic division to divide 0.02x^2 by x, which gives us:
C(x)/x = (0.02x + 92 + 15,000/x)
As x approaches infinity, the term 15,000/x approaches zero, so we can ignore it.
Therefore, the limit of C(x)/x as x approaches infinity is:
lim (x → ∞) (0.02x + 92) = ∞
This means that the average cost function does not have a horizontal asymptote.
However, the limit of the difference between the average cost function and the oblique asymptote as x approaches infinity is zero.
To find the oblique asymptote, we need to divide the polynomial 0.02x^2 + 92x + 15,000 by x.
Using long division or synthetic division, we get:
0.02x + 92 + 15,000/x
Therefore, the oblique asymptote of the average cost function C(x) is:
y = 0.02x + 92

There are no critical numbers for the function g(x) = 4x - 4 on the interval (-3, 1].

Consider the following function: g(x) = x + 3x - 4. To find the derivative of the function, we first need to simplify the function: g(x) = 4x - 4.

Now we can find the derivative, g'(x), using basic ndifferentiation rules:

g'(x) = d/dx (4x - 4) = 4

Next, we need to find any critical numbers of the function. Critical numbers occur when the derivative is either equal to zero or undefined. In this case, g'(x) = 4, which is a constant and never equal to zero nor undefined.

The requirements for a one-sample t-test are generally satisfied assuming a simple random sample and a large enough sample size. However, we cannot determine if the normality requirement is met without examining the data.

To test the claim that the sample is from a population with a mean greater than 80 sec, we need to perform a one-sample t-test. The following requirements must be satisfied to use the one-sample t-test:

The sample must be a simple random sample from the population.

The variable under study must be continuous or approximately continuous.

The population must be normally distributed or the sample size should be large (n > 30).

To determine if the requirements are satisfied for the given data, we need to check if the sample is a simple random sample, the variable (duration times of drug use) is continuous or approximately continuous, and if the population is normally distributed or the sample size is large enough.

Assuming that the sample is a simple random sample, we can check the other requirements:

Continuity: The variable (duration times of drug use) is continuous.

Normality: We can examine a histogram, a normal probability plot, or conduct a normality test such as the Shapiro-Wilk test. If the data is approximately normally distributed, we can proceed with the t-test. If not, we can use a non-parametric test.

Without the data, we cannot determine if the normality requirement is met. However, if the sample size is large (n > 30), we can use the central limit theorem to assume normality. In that case, we can proceed with the t-test.

Therefore, the requirements for a one-sample t-test are generally satisfied assuming a simple random sample and a large enough sample size. However, we cannot determine if the normality requirement is met without examining the data.

19 mm = 1.9 cm

4.1 cm = 41 mm

1.) mm²

19 × 41 = 779 mm²

2.) cm²

1.9 × 4.1 = 7.79 cm²

The area of rectangle in centimeters is 7.79 cm² and Area of rectangle in mm² is 779 mm²

The area of Rectangle is length times of width.

In the given rectangle length is 4.1 cm

Width is 19 mm

Let us convert 4.1 cm to millimeters

We know that 1 cm = 10 millimeters

4.1 cm =4.1×10 mm

=41 millimeters

Now convert 19 mm to centimeter

19 mm = 1.9 cm

Now let us find area of rectangle in cm²

Area of rectangle =4.1 cm×1.9 cm

=7.79 cm²

Area of rectangle in mm²

Area of rectangle =41 mm×19 mm

=779 mm²

Hence, the area of rectangle in centimeters is 7.79 cm² and area of Area of rectangle in mm² is 779 mm²

The probability of getting 230 heads or less out of 500 coin tosses using the normal curve approximation to the binomial distribution is 0.041.

To find the probability of getting 230 heads or less out of 500 coin tosses using the normal curve approximation to the binomial distribution, we need to calculate the mean and standard deviation of the binomial distribution.
The mean of the binomial distribution is given by:

μ = np where n is the number of trials (500 in this case) and p is the probability of getting a head on a single trial (0.5).
μ = 500 * 0.5 = 250
The standard deviation of the binomial distribution is given by:
σ = sqrt(np(1-p))
σ = sqrt(500 * 0.5 * 0.5) = 11.18
Now, we can use the normal distribution with mean μ = 250 and standard deviation σ = 11.18 to find the probability of getting 230 heads or less.
To do this, we first standardize the value of 230 using the formula:
z = (x - μ) / σ where x is the value we are interested in (230 in this case).
z = (230 - 250) / 11.18 = -1.79
Next, we use a standard normal distribution table (or a calculator) to find the probability of getting a value less than or equal to -1.79. This probability is approximately 0.041.

Using the Trapezoid Rule, the value of the integral is -50.125 and by Simpson's Rule, the value of the integral is -54.375.

To estimate the value of the integral (1 – (3x3 + 2x² + 3x)) dx from -1 to 2 using the Trapezoid Rule with n=2 subdivisions, we first need to determine the width of each subdivision:

h = (2 - (-1))/2 = 1.5

Using the Trapezoid Rule formula with n = 2, we have:

∫(-1 to 2) (1 – (3x3 + 2x² + 3x)) dx ≈ (h/2) [f(-1) + 2f(-0.5) + 2f(1) + f(2)]

where f(x) = 1 – (3x3 + 2x² + 3x)

Now we can substitute the function values at each point and simplify:

f(-1) = 1 - (3(-1)³ + 2(-1)² + 3(-1)) = 1

f(-0.5) = 1 - (3(-0.5)³ + 2(-0.5)² + 3(-0.5)) ≈ 0.125

f(1) = 1 - (3(1)³ + 2(1)² + 3(1)) = -7

f(2) = 1 - (3(2)³ + 2(2)² + 3(2)) = -43

Therefore, using the Trapezoid Rule with n=2, we get:

∫(-1 to 2) (1 – (3x3 + 2x² + 3x)) dx ≈ (1.5/2) [1 + 2(0.125) + 2(-7) + (-43)] ≈ -50.125

To estimate the value of the integral using Simpson's Rule with n=2 subdivisions, we use the formula:

∫(-1 to 2) (1 – (3x3 + 2x² + 3x)) dx ≈ (h/3) [f(-1) + 4f(-0.5) + 2f(0) + 4f(0.5) + f(1)]

where f(x) = 1 – (3x3 + 2x² + 3x)

Using the same values of h and f(x) as before, we get:

f(0) = 1 - (3(0)³ + 2(0)² + 3(0)) = 1

Substituting these values in the Simpson's Rule formula, we get:

∫(-1 to 2) (1 – (3x3 + 2x² + 3x)) dx ≈ (1.5/3) [1 + 4(0.125) + 2(1) + 4(-7) + (-43)] ≈ -54.375

Therefore, using Simpson's Rule with n=2, we estimate the value of the integral to be approximately -54.375.
