Answer:
B. Set the alpha level at 0.05.
Step-by-step explanation:
Hypothesis testing is a procedure whereby a researcher determines if the null hypothesis is rejected or accepted, depending on the significant level or the alpha level. When a type I error is made, the null hypothesis is rejected even though it is correct. To solve this problem, the significant or alpha level is set to 5% or 0.05.

If f(x)=2x-3 find the following
f(7)=
f(-2)=
f(-4)=
Step-by-step explanation:
f(x)=2x-3
now,
f(7)=2× 7-3
=14-3
=11
f(-2)='-2×7-3
= -14-3
b= -17
f(-4)= -4×7-3
= -28-3
= -31
The value of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 respectively.
What is a function?A certain kind of relationship called a function binds inputs to essentially one output.
A function can be regarded as a computer, which is helpful.
The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.
In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.
Given,
f(x)=2x-3
f(7) so put x = 7
f(7) = 2(7) - 3
f(7) = 11
Now,
f(-2) so put x = -2
f(-2) = -2×7-3
f(-2) = -17
Now,
f(-4) so put x = -4
f(-4)= -4×7-3
f(-4) = -31
Hence,The value of f(7) ,f(-2) and f(-4) will be 11 , -17 and -31 respectively.

Answer:
4 gallons
Step-by-step explanation:
if 1/4 a gallon is 1/16 of the wall that means 1 gallon is 4/16 of the wall plus another gallon that's 8/16 of the wall plus 2 more gallons that's 16/16 (the whole wall is complete) of the wall
The point (3, y) lies on the line y = 4x + 5. Find the value of y.
Answer:
y = 17
Step-by-step explanation:
y = 4x + 5
since the x value is 3 you substitute it in
y = 4(3) +5
y = 12 +5
y = 17

Find the characteristic polynomial and the eigenvalues of the matrix.
[5 3]
[-4 4]
Answer:
Step-by-step explanation:
Given the matrix
[5 3]
[-4 4]
The characteristic polynomial is expressed as |A - λI| = 0 where λ are the eigen values and I is am identity matrix A 2*2 identity matrix is expressed as;
[1 0]
[0 1]
Substitute into expression will give;
[tex]= \left[\begin{array}{cc}5&3\\-4&4\\\end{array}\right] - \lambda \left[\begin{array}{cc}1&0\\0&1\\\end{array}\right] = 0\\= \left[\begin{array}{cc}5&3\\-4&4\\\end{array}\right] - \left[\begin{array}{cc}\lambda &0\\0&\lambda \\\end{array}\right] = 0\\= \left[\begin{array}{cc}5-\lambda&3\\-4&4-\lambda\\\end{array}\right] = 0[/tex]
Find the determinant of the resulting matrix;
|A - λI| = (5- λ)(4- λ)- 3(-4) = 0
|A - λI| = 20-5 λ-4 λ+ λ²+12 = 0
|A - λI| = 20-9λ+λ²+12 = 0
-9λ+λ²+32 = 0
Rearrange;
λ²-9λ+32 = 0
Hence the characteristic polynomial is expressed as λ²-9λ+32 = 0
Get the eigen values by finding the roots of the equation;
λ = 9±√9²-4(1)(32)/2
λ = 9±√81-(128)/2
λ = 9±√-47/2
λ = 9±√-47/2
λ₁ = 9-√47 i/2 and λ₂ = 9+√47 i/2

45% of a school brought in permission slips for Skateland. If the school received 150 permission slips, how many students are there in the school?
Step-by-step explanation:
What is 45% of 150?
Y is 45% of 150
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 45% * 150
Converting percent to decimal:
p = 45%/100 = 0.45
Y = 0.45 * 150
Y = 67.5

Mrs. Hopkins made four different pies for Thanksgiving dinner at her house. Each pie was the same size.
She cut the blueberry pie into 6 equal slices, the apple pie into 5 equal slices, the peach pie into 3 equal
slices, and the chocolate pie into 4 equal slices.
Her grandchildren. Alyssa, Bobby, Caitlin, and Dylan, each had one slice of pie but only ate a portion of
that slice. Each grandchild chose a different kind of pie.
Alyssa had the largest slice available and ate 1/4 of it
Bobby had the smallest slice available and ate 3/4 of it.
(The slice Caitlin had was larger than the slice Dylan had.)
Caitlin ate 1/2 of her slice.
• Dylan ate 2/3 of his slice.
What kind of pie did each person choose? And what fraction of the total pie did each person eat?

1. One week a student exercised 3 hours at school and 1/4 hour at home. If 1/4 of the student's total exercise came from playing basketball, how much time did the student spend playing basketball that week?
2. One week a student exercised 2 hours at school and 1/4 hour at home. If 1/4 of the student's total exercise came from playing soccer, how much time did the student spend playing soccer that week?
Answer:
1- The student spent 48 minutes and 45 seconds playing basketball.
2- The student spent 33 minutes and 45 seconds playing soccer.
Step-by-step explanation:
1- If during a week the student exercised for 3 hours at school, and for 1/4 hour at home, it could be said that the student exercised for a total of 195 minutes (60 x 3 + 60/4) . Now, if I exercise 1/4 of that time playing basketball, the student spent 48 minutes and 45 seconds playing that sport (195/4).
2- If during a week the student exercised for 2 hours at school, and for 1/4 hour at home, it could be said that the student exercised for a total of 135 minutes (60 x 2 + 60/4) . Now, if I exercise 1/4 of that time playing basketball, the student spent 33 minutes and 45 seconds playing soccer (135/4).
