Cosine is adjacent over hypotenuse.

So for Angle Z, the adjacent leg is 12 and the hypotenuse leg is 20.

The Cosine ratio is 12/20.

16 is not used and would be the opposite leg to Angle Z

The dunking booth is the shape of a cube represented below (x+3). Therefore, the polynomial of volume of the dunking booth is

                                            (x +3) (x+3)².

Lets talk about the cube prism

- It has cube faces each two opposite faces are congruent

- It has three dimensions.

- Its volume = a³

In our problem the dunking booth is a cube prism with dimensions:  x + 3

Side = x +3

therefore,

V = a³ = ( x +3)³

          = (x)³ + 3× (x)²× 3 + 3× x × (3)² + (3)³

          = x³ + 9x² + 27x + 27

Regrouping ,

          = x³+ 27+ 9x² + 27x

Rewrite 27as 33.

x³+ 3³+9x²+ 27x

Since both terms are perfect cubes, factor using the sum of cubes formula,

a³+b³ = (a + b)(a²- ab+ b²) where a=x and b=3.

(x+3)(x− x⋅3 + 32)+ 9x²+ 27x

Simplify.

     (x+3)(x²− 3x + 9)+ 9x²+ 27x

⇒  (x+3)(x²− 3x + 9)+ 9x(x+3)

Now,

x+3 out of  (x+3)(x²− 3x + 9)+ 9x(x+3) .

⇒ (x+3)(x²− 3x + 9 + 9x)

Add −3x and 9x.

(x+3) (x²+ 6x+ 9)

Rewrite the polynomial.

   (x+3)(x²+ 2⋅x⋅3+ 3²)

Factor using the perfect square trinomial rule a²+2ab+b² = (a + b)² , where a = x and b = 3.

                  (x+3)(x+3)².

Therefore, the polynomial is   (x+3)(x+3)².

The variables of the test statistic can be concluded as [tex]s_{1} ^{2}[/tex], [tex]s_{2} ^{2}[/tex] as the variance of two samples, [tex]n_{1}[/tex], [tex]n_{2}[/tex] as the respective size of the two samples, [tex]t[/tex] as the t-distribution test statistic, and [tex]x_{1}[/tex], [tex]x_{2}[/tex] as the mean of the two samples.

It is given to us that the test statistic is used for a two sample test of means where the population variances are unknown and unequal.

Pooled standard deviation estimates cannot be used when the two groups have unequal variances. Instead, we have to find out the standard error for each group separately.

The formula for this type of test statistic is given by -

[tex]t=\frac{x_{1} -x_{2} }{\sqrt{\frac{s_{1} ^{2} }{n_{1} } +\frac{s_{2} ^{2} }{n_{2} } } }[/tex] ------- (1)

Here, the variables can be defined as below -

[tex]s_{1} ^{2}[/tex], [tex]s_{2} ^{2}[/tex] = The variance of two samples

[tex]n_{1}[/tex], [tex]n_{2}[/tex] = The respective sizes of the two samples

[tex]t[/tex] = t-distribution test statistic

[tex]x_{1}[/tex], [tex]x_{2}[/tex] = Mean of the two samples

Thus, the variables of the test statistic can be concluded as [tex]s_{1} ^{2}[/tex], [tex]s_{2} ^{2}[/tex] as the variance of two samples, [tex]n_{1}[/tex], [tex]n_{2}[/tex] as the respective size of the two samples, [tex]t[/tex] as the t-distribution test statistic, and [tex]x_{1}[/tex], [tex]x_{2}[/tex] as the mean of the two samples.

Answer: (x+5)(x+2)^2

Step-by-step explanation: Expanding (x+5)(x+4)(x+4) gives:

(x+5)(x+4)(x+4) = x(x+4)(x+4) + 5(x+4)(x+4)

= x^2(x+4) + 4x(x+4) + 5x(x+4) + 20(x+4)

= x^3 + 4x^2 + 5x^2 + 20x + 16x^2 + 80x + 20x + 80

= x^3 + 9x^2 + 45x + 80

Fully simplifying this expression gives:

x^3 + 9x^2 + 45x + 80 = (x+5)(x^2+4x+16)

There is a 0.890 percent chance that headway will be within one standard deviation of the mean.

The mean value is what?

The mean, or average of the given numbers, is calculated by dividing the sum of the numbers by the total number of numbers.

The sum of all possible values, weighted by the likelihood of each value, constitutes the mean of a discrete probability distribution of the random variable X. Each possible value of X must be multiplied by its probability, P(x), before being added to determine the mean.

P(0.995 ≤ x ≤ 1.445) = F(1.445) - F is the given mean value (0.995).

The distribution's cdf is

f(x) = { (1 - 1/x⁶ , x > 1) (0. x ≤ 1)

Determine the values of F(1.445) and F now (0.995).

F(1.445) = 1 - (1/(1.445)⁶)

F(0.995) = 0

Now, using the values of F(1.445) and F(0.995) in P( 0.995 ≤ x ≤ 1.445) to get F(1.445) - F(0.995):

P( 0.995 ≤ x ≤ 1.445)

The number 2.9 × 10^3 is 126 times smaller than 3.654 × 10^5. Because its ratio is 126. It can be calculed by the concept of ratio.

What is ratio?

It is the way of representation of a quantity relative to the other quantity. Its symbol is :. For example size of 2 relative to 5 is represented by 2:5 or 2/5.

To find how many times 2.9 × 10^3 is smaller than 3.654 × 10^5, take ratio of 3.654 × 10^5 and 2.9 × 10^3 as follows:

[tex]=\frac{3.654\times 10^5}{2.9 \times10^3}\\[/tex]

Now, subtract the indices as follows:

[tex]=\frac{3.654\times 10^2}{2.9}\\[/tex]

Now, divide the number as follows:

[tex]=1.26\times 10^{2}\\[/tex]

Now, write in simplest form as follows:

The Python program prints the value of the integer n from the input string shown. (Refer to the coding below)

An arrangement of Python statements that have been specifically designed to accomplish a task is the simplest definition of a program.

A program is even our straightforward hello.py script.

Although it is only one line long and of limited use, it is a Python program by the strictest definition.

Functions assist in segmenting our program into manageable, modular portions.

Our program becomes more organized and controlled as it gets bigger and bigger.

It also makes the code reusable and prevents repetition.

So, we know that the program is for the given integer n:

Defining the integer variable "N" that accepts a user-supplied integer value.

The user-end string value is input using another variable "W" that is declared in the next step.

A for loop using the range method and an integer variable is declared after all input values have been entered.

This loop prints the string value.

The Python program prints the value of the supplied string.

N= int(input("Enter a value of integer N (0 <= N <= 100): "))#defining an integer variable N that inputs integer value from the user-end

W = input("Enter the word W (length of 1 <= L <= 50): ")#defining a string variable W that inputs the value fom the user-end

for n in range(N):#defining a for loop that uses the range method with integer variable and prints the string value

The polynomial equation with zeroes of -3, -1, 2 and y-intercept of -14 is x^3 +2x^2 -5x -20.

The zeros of a function f(x) are values of the variable x such that the values satisfy the equation f(x) = 0. The zeros of a function are also called the roots of a function.

if -3, -1, 2 are zeroes of y(x) with an intercept d then

y(x) = (x-a)(x-b)(x-c) + d

where a = -3, b = -1, c = 2, d = -14

Substituting we have

y(x) = (x+3)(x+1)(x-2) -14

let us expand the first two linear factors

(x+3)(x+1) =x^2 +3x + x + 3 which is x^2 + 4x + 3

multiply this result with (x-2), we have

(x-2)(x^2 + 4x +3)

x^3 + 4x^2 +3x -2x^2 -8x -6

simplifying it becomes x^3 +2x^2 -5x -6

y(x) =  x^3 +2x^2 -5x -6 -14

y(x) = x^3 +2x^2 -5x -20

We have the given information:

The height of the person is 7 ft.

The person is walking away from the post at a rate of 5ft/sec.

The height of the lamppost is 20ft.

Let the person's distance from the bottom of the light post be x ft.

And his shadow's length is y ft.

Answer:

Step-by-step explanation:

The breadth of the confidence interval grows as the confidence level does. The breadth of the confidence interval reduces as the confidence level rises.

Generally speaking, the more information we know on the level of the population parameter, the narrower a confidence interval becomes. As a result, we want to make sure that all of the confidence intervals are as small as feasible. So let's look at the variables that influence the mean's t-interval width.

The margin of error grows as the degree of confidence does because we require a broader interval to improve our level of confidence that the interval includes the population mean.

Because the standard error is reduced as sample size increases, confidence intervals are narrower.
