The probability of getting at least 2 tails in 4 coin tosses is 11/16 or approximately 0.6875.

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

To determine P(at least 2 tails), we need to add up the probabilities of all the outcomes in the sample space that have at least 2 tails.

Looking at the tree diagram, we can see that there are 11 outcomes that have at least 2 tails:

TTTT TTTH TTHT TTHH THTT THHT THTH HTTT HTTH HTHT HHTT

The probability of each outcome can be found by multiplying the probabilities along the branches that lead to that outcome. Since the coin is fair, the probability of getting heads or tails on any given toss is 1/2.

So for example, the probability of the outcome TTHH is (1/2) x (1/2) x (1/2) x (1/2) = 1/16.

We can find the probability of getting at least 2 tails by adding up the probabilities of the 11 outcomes listed above:

P(at least 2 tails) = [tex](1/2)^4[/tex] + 4 x [tex](1/2)^3[/tex] x (1/2) + 6 x [tex](1/2)^2[/tex] x [tex](1/2)^2[/tex]

P(at least 2 tails) = 1/16 + 4/16 + 6/16 = 11/16

Therefore, the probability of getting at least 2 tails in 4 coin tosses is 11/16 or approximately 0.6875.

Answer:

(c) 6 days

Step-by-step explanation:

First, we need to calculate how many trips the truck can make per day. We will assume that the truck is filled to its maximum capacity on each trip.

The volume of the truck can be calculated by multiplying its dimensions:

8.17 feet x 9.25 feet x 18.5 feet = 1,482.51 cubic feet

We need to convert this to cubic meters:

1,482.51 cubic feet x 0.0283 cubic meters per cubic foot = 42.01 cubic meters

Therefore, each round trip can transport 42.01 cubic meters of construction waste.

To calculate how many trips are required to remove all the waste, we divide the total volume of waste by the volume of waste per trip:

1,425 cubic meters / 42.01 cubic meters per trip = 33.89 trips

Since the driver can make one round trip per hour, it will take approximately 34 hours to transport all the waste to the landfill.

If the driver starts on Monday at 8 am, they will have 8 working hours that day, for a total of 8 trips. On Tuesday and Wednesday, they will have 8 working hours each day, for a total of 16 trips. Therefore, by noon on Wednesday, they will have made 24 trips, leaving 9.89 trips remaining.

Since each day the driver can make 8 trips, they will need approximately 2 more days of work to completely remove the construction waste from the demolition site. Therefore, the answer is (c) 6 days.

Note: This calculation assumes that there are no delays or complications in the transportation process, such as traffic or equipment malfunctions, which could affect the actual time required to remove all the waste.

Answer:

y = (360 - 117 - 75) / 2 = 84 degrees

Step-by-step explanation:

a) The shape shown in the image could be described as a kite.

b) Since the opposite angles in a kite are equal, we can find the measure of angle y by subtracting the measures of angles x and z from 360 degrees and then dividing by 2, since the sum of the interior angles of a quadrilateral is always 360 degrees. Thus, we have:

y = (360 - x - z) / 2

We can see from the figure that angle x has a measure of 117 degrees, since it is opposite to angle y in one of the congruent triangles formed by the diagonal of the kite. Similarly, angle z has a measure of 75 degrees, since it is opposite to angle y in the other congruent triangle. Substituting these values into the above equation, we get:

y = (360 - 117 - 75) / 2 = 84 degrees

Therefore, the measure of angle y is 84 degrees.

We can see that opposite sides of the quadrilateral are parallel and equal in length, which indicates that the shape is a parallelogram.

To find the size of angle y, we can use the fact that opposite angles in a parallelogram are equal. Let's call the angle at the bottom left corner of the parallelogram "x". Then, we know that:

x + y = 180° (because the two angles form a straight line)

We also know that the angle at the top left corner of the parallelogram is equal to x (because opposite angles in a parallelogram are equal). And since the four angles of a quadrilateral add up to 360°, we can write:

2x + 2y = 360°

Simplifying this equation gives:

x + y = 180°

x + y = 180° - x + y

2x = 180° - x

3x = 180°

x = 60°

Now we can substitute x = 60° into the equation x + y = 180° to solve for y:

60° + y = 180°

y = 180° - 60°

y = 120°

Therefore, the size of angle y is 120°.

What is quadratic equation?

it's a second-degree quadratic equation which is an algebraic equation in x. Ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term, is the quadratic equation in its standard form. A non-zero term (a 0) for the coefficient of x2 is a prerequisite for an equation to be a quadratic equation. The x2 term is written first, then the x term, and finally the constant term is written when constructing a quadratic equation in standard form. In most cases, the numerical values of letters a, b, and c are expressed as integral values rather than fractions or decimals.

To find the zeros of the function [tex]y=7x^3-7x[/tex], we can set y equal to zero and solve for x:

[tex]7x^3 - 7x = 0[/tex]

Factor out 7x:

[tex]7x(x^2 - 1) = 0[/tex]

Factor the quadratic expression:

7x(x - 1)(x + 1) = 0

The zeros of the function are the values of x that make y equal to zero. From the factored expression, we see that the zeros are:

x = 0 (with multiplicity 1)

x = 1 (with multiplicity 1)

x = -1 (with multiplicity 1)

Answer:

x = 57°

Step-by-step explanation:

We are given a triangle, and we know that the angles in the triangle are <A, <B, and <C.

We know that m<A = 78° and  m<B=45°. We want to find the measure of angle C, which we know currently as x.

Recall that all angles in a triangle add up to 180°. This means that m<A + m<B + m<C = 180°.

Substituting what we know into that equation, we get:

78° + 45° + x = 180°

We can add 78 and 45 degrees together.

123° + x = 180°

Subtract 123° from both sides.

x = 57°

So x, or m<C is 57°.

Step-by-step explanation:

remember, the general equation for a circle is

(x - h)² + (y - k)² = r²

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

the line (0, 8) to (0, -2) is a diameter, so, the center of the circle is the midpoint between both points.

remember, the midpoint between 2 points (x1, y1) and (x2, y2) is

((x1+x2)/2, (y1+y2)/2)

in our case :

((0+0)/2, (8-2)/2) = (0, 3)

the distance from the center point to the endpoint is e.g

(0, 3) to (0,8) = 8-3 = 5.

and that is the radius.

the equation of the circle is therefore :

(x - 0)² + (y - 3)² = 5²

x² + (y - 3)² = 25

As a result, the following is the given function's Fourier transform:

F(ω) = (1/π) * (sin(ω) / ω)

The Fourier transform is a mathematical operation that separates the frequencies that make up a waveform, which is a function of time. The Fourier transform's output is a complex valued function of frequency.

We must assess the integral in order to determine the given function's Fourier transform, f(x):

F() is equal to 1/(2) * [from - to -] F(x) E(-i) X Dx

where the frequency parameter is and i is the fictitious unit.

We can simplify the integral bounds as follows since the function f(x) is non-zero only in the range -1 x 1.

F() is equal to 1/(2)*[from -1 to 1] F(x) E(-i) X Dx

Let's analyse this integral in stages.

The value of the function f(x) is zero for x -1 or x > 1. As a result, we can increase the integral limits to - and + without changing the integral's value:

F(ω) = 1/(2π) * ∫(from - to -) F(x) = E(-ix) dx = 1/(2*) * the range [- to -1] from -1 to 1 + 0 dx 2dxe(-ix)+[from 1 to ] 0 dx = 1/(2π) * 2 * ∫E(-ix) dx [from -1 to 1]

Let's concentrate on the central integral:

∫[in the range of -1 to 1] e(-ix) dx = (-1/i)* [e^(-iωx)](-1/i)* _[from -1 to 1] (e^(-iω) - e^(iω))

Adding this back into the formula for the Fourier transform results in:

F(ω) = 1/(2π) * 2 * (-1/iω) * (e^(-iω) - e^(iω)) = (1/π) * (sin(ω) / ω)

As a result, the following is the given function's Fourier transform:

What is Fourier Analysis?

Fourier analysis is a branch of mathematics that deals with the study of the decomposition of a complex signal into simpler components, known as harmonics, using a mathematical tool called the Fourier transform.

To find the Fourier transform of the given function f(x), we need to use the following formula:

F(ω) = ∫ f(x) e^(-iωx) dx

where F(ω) denotes the Fourier transform of f(x) and ω is the frequency variable.

Let's apply this formula to the given function f(x):

F(ω) = ∫ f(x) [tex]e^{(-iωx)}[/tex] dx

= ∫[tex]-1^{1}[/tex] 2 [tex]e^{(-iωx)}[/tex] dx + ∫{-∞}^{∞} 0 [tex]e^{(-iωx)}[/tex] dx

= 2 [ (cos(ω) - i sin(ω)) / iω - (cos(ω) + i sin(ω)) / iω ]

= 2 [ -2i sin(ω) / (2iω) ]

To find the LCM of the two expressions, we need to factor each expression completely and then take the product of the highest powers of each factor.

So, let's factor each expression:

6(x – 1)2(x + 2)(x – 3) = 2 × 3 × (x – 1) × (x – 1) × (x + 2) × (x – 3)

9(x – 1)(x + 2)2(x – 3) = 3 × 3 × (x – 1) × (x + 2) × (x + 2) × (x – 3)

Now, we can identify the highest powers of each factor.

The LCM will be the product of those highest powers:

LCM = 2 × 3 × 3 × (x – 1)2 × (x + 2)2 × (x – 3)

Therefore, the LCM of 6(x – 1)2(x + 2)(x – 3) and 9(x – 1)(x + 2)2(x – 3) is 54(x – 1)2(x + 2)2(x – 3).

To solve this problem, we can use the combination formula, which is:

n C r = n! / (r! * (n-r)!)

where n is the total number of students eligible for the committee, r is the number of students we want to choose, and ! denotes the factorial function.

In this case, we want to choose a committee of 8 students from a pool of 8 freshmen, 9 sophomores, 8 juniors, and 10 seniors. So, the total number of students eligible for the committee is:

n = 8 + 9 + 8 + 10 = 35

We want to choose a committee of 8 students, so r = 8. Therefore, the number of ways we can choose a committee of 8 students is:

35 C 8 = 35! / (8! * (35-8)!) = 35! / (8! * 27!) ≈ 1,121,112 ways

So there are approximately 1,121,112 ways to choose a dance committee of 8 students from the eligible pool.
