Answer:

12 dollars

Step-by-step explanation:

she spent 4 dollars for each of 3 kids so what I did was multiply 3 times 4, and got 12 dollars then she spent 5 dollars on her self which was 17 dollars she spent in the coffee shop.

Answer:

n=6

"=T.INV(1-0.025,5)", and we got the critical values given by:  

n=12

"=T.INV(1-0.025,11)", and we got the critical values given by:  

Step-by-step explanation:

Previous concepts

The t distribution (Student’s t-distribution) is a "probability distribution that is used to estimate population parameters when the sample size is small (n<30) or when the population variance is unknown".

The shape of the t distribution is determined by its degrees of freedom and when the degrees of freedom increase the t distirbution becomes a normal distribution approximately.  

The degrees of freedom represent "the number of independent observations in a set of data. For example if we estimate a mean score from a single sample, the number of independent observations would be equal to the sample size minus one."

Solution to the problem

For n=6

In order to find the critical value we need to take in count that we are conducting a two tailed test, so we are looking on the t distribution with df=n-1=6-1=5 degrees of freedom, a value that accumulates of the area on each tail. We can use excel or a table to find it, for example the code in Excel is:  

"=T.INV(1-0.025,5)", and we got the critical values given by:  

For n=12  

In order to find the critical value we need to take in count that we are conducting a two tailed test, so we are looking on the t distribution with df=n-1=12-1=11 degrees of freedom, a value that accumulates of the area on each tail. We can use excel or a table to find it, for example the code in Excel is:  

"=T.INV(1-0.025,11)", and we got the critical values given by:  

The inverse of the function will be f⁻¹(x) = [√(x) - 1] / 2 for x ≥ 0.

What is the inverse function?

Let the function f is given as

y = m(x + a) + c

Then the inverse function of the function f will be given by the swapping of x with y and y with x.

The quadratic function is given below.

f(x) = (2x + 1)²

Then the inverse of the quadratic function will be

x = (2f⁻¹(x) + 1)²

2f⁻¹(x) + 1 = √x

2f⁻¹(x) = √x - 1

f⁻¹(x) = [√(x) - 1] / 2 for x ≥ 0

The inverse of the function will be f⁻¹(x) = [√(x) - 1] / 2 for x ≥ 0.

More about the inverse function is given below.

Answer:

The integer would be -12

Step-by-step explanation:

x + 5 = -7

  -5      - 5

x = -12

-12 + 5 = -7

y intercept Y=3

I only know the y intercept have a good day

Answer:

a. 20.5

Step-by-step explanation:

because this will form a right triangle we can use tan (opposite over adjacent) so an equation we could set up would be tan(70)=25/x

therefore we can just solve the equation which would give us 20.45. so if we round it the answer would be a

Answer:

The correct answer option is a. 20.5 feet.

Step-by-step explanation:

We are given that the angle of elevation of the ladder is 70° and the height of the ladder is 25 feet from the ground.

We are to find the distance of the building from the base of the ladder.

For this, we will use tan:

x = 20.5 feet
