Y+8=2 solve for y show your work

the probability that the correct combination is written on the paper is 1/1000, or 0.001.

How to solve?

To find the probability that the correct combination is written on the paper, you need to first determine the total number of possible combinations that can be created with the 3 wheels, each numbered from 0 to 9. This can be done using the multiplication principle, which states that if there are m ways to perform one task and n ways to perform another task, then there are m × n ways to perform both tasks.

So, the total number of possible combinations is:

10 × 10 × 10 = 1000

This means that there are 1000 possible combinations for the lock.

Next, you need to determine the number of ways you can choose five different numbers from 0 to 999. This can be done using the combination formula, which is:

nCr = n! / r!(n - r)!

where n is the total number of items to choose from, r is the number of items to choose, and ! represents the factorial function (i.e., the product of all positive integers up to and including that number).

So, the number of ways to choose five different numbers from 0 to 999 is:

nCr = 1000! / 5!(1000 - 5)!

nCr = 1000! / 5!995!

nCr = (1000 × 999 × 998 × 997 × 996) / (5 × 4 × 3 × 2 × 1)

nCr = 831,600,000

This means that there are 831,600,000 ways to choose five different numbers from 0 to 999.

Finally, to find the probability that the correct combination is written on the paper, you need to divide the number of ways to choose the correct combination (which is 1) by the total number of possible combinations:

P(correct combination) = 1 / 1000

So, the probability that the correct combination is written on the paper is 1/1000, or 0.001.

Answer:

The exponential decay function of the rabbit population P(t) can be expressed as:

P(t) = 144,000 * e^(-0.072t)

Step-by-step explanation:

Where t is the time in years.

This function represents the expected decrease in the rabbit population of Springfield, Ohio, assuming a constant rate of decline of about 7.2% per year. The initial population of rabbits in 2016 was 144,000, and this number is multiplied by the exponential factor e^(-0.072t), which represents the proportion of rabbits that will remain after t years.

As time passes, the value of P(t) will decrease exponentially, reflecting the declining rabbit population. For example, after one year (t=1), the rabbit population is expected to be:

P(1) = 144,000 * e^(-0.072*1) = 133,632

This means that the rabbit population is expected to decrease by about 10,368 rabbits in the first year.

The exponential decay function is commonly used in many fields to model phenomena that exhibit exponential decay over time, such as radioactive decay, bacterial growth, and population dynamics.

Using the probability, we can find that when a single card is drawn from the deck, the probability of not drawing a king is 12/13.

The ability to occur is known as probability. The occurrence of random events is the subject of this branch of mathematics. The value is expressed as a number between 0 and 1. Probability has been introduced in mathematics to predict how likely events are to occur.

Here the total number of cards in a deck is 52.

There are four jacks, four queens, and four kings in a deck of 52 cards. Twelve face cards follow.

If we choose one of the king cards here, then:

Probability of drawing a king will be:

P = 4/52

= 1/13

Now, we have to find the probability of not drawing a king, so:

Probability = 1 - 1/13

= 13-1/13

=12/13

Therefore, when a single card is drawn from the deck, the probability of not drawing a king is 12/13.

We can use the Law of Sines to solve for the sides of the triangle. The Law of Sines states that for any triangle with sides a, b, and c opposite angles A, B, and C, respectively:

a/sin A = b/sin B = c/sin C

We can use this formula to solve for any side of a triangle if we know the measures of two angles and the length of one side.

Let's label the sides of the triangle as follows:

a is opposite angle A (which measures 47°)

b is opposite angle B (which measures 36°)

c is opposite angle C (which measures 97°)

We want to find the largest side, so let's solve for all three sides using the Law of Sines and then compare them:

a/sin 47° = b/sin 36° = c/sin 97°

Solving for a:

a = sin 47° (b/sin 36°) = (sin 47°/sin 36°) b

Solving for b:

b = sin 36° (a/sin 47°) = (sin 36°/sin 47°) a

Solving for c:

c = sin 97° (a/sin 47°) = (sin 97°/sin 47°) a

To compare the sides, we can simply compare the coefficients in front of a and b:

a = (sin 47°/sin 36°) b ≈ 1.336 b

c = (sin 97°/sin 47°) a ≈ 2.117 a

Therefore, c is the largest side of the triangle. We can find its exact value by plugging in the given angle measures:

c = (sin 97°/sin 47°) a ≈ 2.117 a

a/sin 47° = c/sin 97°

a = (sin 47°/sin 97°) c ≈ 0.702 c

So the largest side, c, is approximately 2.117 times the length of the smallest side, a. We don't know the actual length of any side, since we don't have any side lengths to use as reference.

Answer:

In any triangle, the sum of the angles is always 180 degrees. So we can use this fact to find the measure of angle A and angle B:

m∠C + m∠A + m∠B = 180

Substituting the given values, we get:

97° + 47° + 36° = 180°

Simplifying this equation, we get:

180° = 180°

This confirms that the given angle measures are valid.

To find the largest side of the triangle, we can use the law of sines, which relates the sides of a triangle to the sines of their opposite angles:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the lengths of the sides opposite angles A, B, and C, respectively.

We want to find the largest side, which is opposite the largest angle. Since angle C is the largest angle, we can set up the proportion:

a/sin(A) = b/sin(B) = c/sin(C)

a/sin(47°) = b/sin(36°) = c/sin(97°)

To find the largest side, we need to find the largest value of the expression a/sin(47°). We can start by finding the value of b/sin(36°) and c/sin(97°) using the given information.

Using the law of sines, we can write:

b/sin(36°) = c/sin(97°)

b = (sin(36°)/sin(97°))c

Now, substituting this expression for b, we get:

a/sin(47°) = (sin(36°)/sin(97°))c/sin(36°)

Simplifying this expression, we get:

a/sin(47°) = c/sin(97°)

a = (sin(47°)/sin(97°))c

Now, we need to find the value of c. Using the law of sines again, we can write:

a/sin(47°) = b/sin(36°) = c/sin(97°)

c = (sin(97°)/sin(47°))a

Substituting the expression we found for a, we get:

c = (sin(97°)/sin(47°))(sin(47°)/sin(97°))c

c = c

So, we see that c is equal to itself, which doesn't give us any new information. However, we can use the expression we found for a to determine the largest side:

a = (sin(47°)/sin(97°))c

Since sin(47°) < sin(90°) and sin(97°) > sin(90°), we know that sin(47°)/sin(97°) < 1. Therefore, the largest side of the triangle is c, which is opposite the largest angle, angle C.

In conclusion, we cannot determine the exact length of the largest side without additional information, but we know that it is opposite angle C, which has a measure of 97 degrees.

Answer:

B(x) appears to be an exponential function because the population increases at a constant rate over time. This can be seen by observing that the population roughly triples with each passing year, indicating that the function is of the form B(x) = ab^x, where a is the initial population and b is the growth factor. To confirm this, we can calculate the growth factor by dividing the population at each successive year by the population in the previous year. For example, we have:

b = B(1)/B(0) = 6/2 = 3

b = B(2)/B(1) = 18/6 = 3

b = B(3)/B(2) = 54/18 = 3

and so on.

M(x) appears to be a quadratic function because the population growth rate is not constant, but rather increases over time. This can be seen by observing that the rate of increase in the population growth appears to accelerate as time goes on, suggesting that the function is of the form M(x) = ax^2 + bx + c, where a, b, and c are constants. To confirm this, we can plot the data and observe that the graph has a parabolic shape.

S(x) also appears to be a quadratic function for similar reasons to M(x), where the population growth rate increases over time.

From the given data, the function S(x) appears to be the same type as W(x) because both are quadratic functions. Both functions appear to have an increasing rate of growth over time.

Step-by-step explanation:

The data presented shows the growth of the Javanese gibbon population on three different islands over time.

Data trends must be analyzed to determine the type of function that is modeling population growth. A common way to do this is to plot the data points and observe the shape of the curve. However, since the table only contains data, you can analyze trends by looking at the differences between consecutive terms.

To do this, we can calculate the first difference and the second difference in the population data.

The first difference:

- Swing: 40 - 30 = 10, 50 - 40 = 10, 60 - 50 = 10

Example: 60 - 50 = 10, 75 - 60 = 15, 90 - 75 = 15

- Salavati: 80 - 60 = 20, 100 - 80 = 20, 120 - 100 = 20

The second difference:

- Batanta: 10 - 10 = 0, 10 - 10 = 0

- Example: 15 - 10 = 5, 15 - 15 = 0

- Salavati: 20 - 20 = 0, 20 - 20 = 0

The first difference is constant for each island and shows a linear relationship between time and population growth. Also, the second difference is zero, indicating a constant rate of change.

Therefore, we can conclude that the population growth modeling function is a linear function that can be written as

M(x) = mx + b

where x is the time in years, m is the slope (population growth rate), and b is the y-intercept (initial population).

The measure of angle KGH is 180° - 48°, or 132°.

Therefore, the size of angle KGH is 48º.

An angle is a portion of a circle, where a circle has 360° in total. A right angle is a quarter of a circle and is 90°, but a straight angle is equal to the circumference of the circle and is 180°. Using a protractor, you can gauge the size of an angle.

Given that GH and EF are parallel, we can infer from the fact that FHE and HFE are at opposing angles that angle HFE must also be 48o.

Since the opposite angles in a parallelogram are equal, we know that angle KGH is also equal to angle HFE, which is 48º.

The choice of auto insurance plan depends on the value of the vehicle and financial situation. Plan 2 with higher coverage and deductibles is better for expensive vehicles and those with higher financial stability.

Insurance is a contract between an individual or an entity and an insurance company. The individual or entity pays a premium, and in return, the insurance company agrees to pay for losses or damages that occur, as per the terms of the policy.

Financial stability refers to a situation where an individual, household, company, or economy can manage their financial resources and obligations in a sustainable manner, without facing significant risks or uncertainty.

According to the given information:

Based on my vehicle's value and my financial situation, I have decided to choose Plan 1.

Bodily injury liability coverage provides protection if I were to injure someone while driving, and the amount of coverage in Plan 1 ($25,000 per person up to $50,000 per accident) is adequate for my needs. Property damage liability coverage provides protection for any damage I might cause to someone else's property while driving, and the $25,000 coverage in Plan 1 is also sufficient.

Collision insurance provides coverage for any damage to my own vehicle in the event of an accident, regardless of who is at fault. The $100 deductible in Plan 1 means that I would have to pay the first $100 of any repair costs, but the lower annual premium makes this plan more affordable for me.

Comprehensive insurance provides coverage for non-collision events, such as theft, fire, and natural disasters. Again, the lower annual premium of Plan 1 with a $50 deductible makes it more cost-effective for me.

Uninsured/underinsured motorist coverage is not included in either plan, so I would need to decide if I want to add this coverage as an additional policy or not.

Overall, based on the value of my vehicle and my financial situation, Plan 1 provides adequate coverage at a more affordable price.

The answer is: The coordinates of point B are (4.3, 2.5)

A scatterplot is a type of graph that shows how two variables relate to each other. The values of the two variables are each represented by a point in the set of points that make up the graph.

Let's first find the distance between points A (1, 5) and C (1.75, 2.5).
We can use the distance formula:

[tex]d = \sqrt{ (x_2 - x_1)^2 + (y_2 - y_1)^2 }[/tex]

where x₁ = 1, y₁ = 5, x₂ = 1.75, and y₂ = 2.5

[tex]d = \sqrt{ (1.75 - 1)^2 + (2.5 - 5)^2 }[/tex]  = [tex]\sqrt{[0.5625 + 6.25]}[/tex] = √6.8125 = 2.61

Now, since the line is divided into four equal parts, the distance between points C and B is also √6.8125.
Let's assume the x-coordinate of point B is "b". The y-coordinate of point B will be the same as the y-coordinate of point C which is 2.5 (since they are on the same horizontal line).

Use the distance formula for the x-coordinate of point B (b, 2.5):

d = √6.8125 = [tex]\sqrt{ [(b - 1.75)^2 + (2.5 - 2.5)^2] }[/tex]

√6.8125  =  [tex]\sqrt{ (b - 1.75)^2 }[/tex]

6.8125 = (b - 1.75)²

6.8125 = b² - 3.5b + 3.0625

Simplifying:

b² - 3.5b - 3.75 = 0

Using the quadratic formula:

b = (3.5 ± √(3.5² + 4(3.75)))/2

b = (3.5 ± √(27.25))/2

b = (3.5 ± 5.22)/2

So, b = 4.36 or b = -0.86. Since the line segment goes from left to right, the x-coordinate of point B must be greater than the x-coordinate of point A (which is 1). Therefore, the answer is:

The coordinates of point B are (4.3, 2.5).

Since the calculated t-value (2.26) is greater than the critical t-value (1.734), we can reject the null hypothesis and conclude that there is sufficient evidence to support the claim that using name-brand microwave popcorn results in a greater percentage of popped kernels than store-brand microwave popcorn at the 0.05 level of significance.

In statistics, a test statistic is a numerical summary of a sample that is used to assess the evidence provided by data in favor of some conjecture about the population from which the sample was drawn. A test statistic compares the observed data to what is expected under the null hypothesis, and measures how many standard errors the observed data deviates from the expected value. Test statistics are used in hypothesis testing to determine the likelihood that an observed effect or difference between groups is due to chance, or whether it is statistically significant.

Here,

To determine if using name-brand microwave popcorn results in a greater percentage of popped kernels than store-brand microwave popcorn, we can compare the mean percentage of popped kernels between the two groups using a hypothesis test.

Let μ1 be the mean percentage of popped kernels for name-brand microwave popcorn and μ2 be the mean percentage of popped kernels for store-brand microwave popcorn.

The null hypothesis is that there is no difference in the mean percentage of popped kernels between name-brand and store-brand microwave popcorn:

H0: μ1 - μ2 = 0

The alternative hypothesis is that the mean percentage of popped kernels for name-brand microwave popcorn is greater than the mean percentage of popped kernels for store-brand microwave popcorn:

Ha: μ1 - μ2 > 0

We can use a two-sample t-test with unequal variances to test this hypothesis. Assuming a significance level of 0.05, the critical t-value for a one-tailed test with 18 degrees of freedom is 1.734.

Using the given data, we find that the sample mean percentage of popped kernels for name-brand microwave popcorn is 90.9% with a sample standard deviation of 5.09%, and the sample mean percentage of popped kernels for store-brand microwave popcorn is 85.9% with a sample standard deviation of 4.67%.

We can calculate the test statistic as follows:

t = (x1 - x2 - 0) / √(s1²/n1 + s2²/n2)

t = (90.9 - 85.9) / √((5.09²/10) + (4.67²/10))

t = 2.26

Therefore, based on this study, using name-brand microwave popcorn is likely to result in a greater percentage of popped kernels than store-brand microwave popcorn.

The square root of the surd expression 4 - 2√5 does not exist

Given that

4-2root5

Express properly

So, we have

4 - 2√5

The root can be expressed as

(√a - √b)

So, we have

(√a - √b)² = 4 - 2√5

Expand

So, we have

a - 2√ab + b = 4 - 2√5

By comparison, we have

a + b = 4

ab = 5

When solved graphically, the system has no solution

Hence, the surd expression has no square root
