It is believed that students who begin studying for final exams a week before the test score differently than students who wait until the night before. Suppose you want to test specifically that students who study earlier have an average score that is less than the average score for students who wait to study. What are the hypotheses for this test if early studiers are group 1 and procrastinators are group 2
Answer:
H0 : μ1 = μ2
H0 : μ1 < μ2
Step-by-step explanation:
Given :
Early studiers, group 1, mean μ1
Late studiers, group 2 ; mean, μ2
To test the claim that students who study earlier have an average score that is less than the average score for students
The null hypothesis ; there is no difference in average score
H0 : μ1 = μ2
Alternative hypothesis is early studiers means is less than average score of late studiers
H0 : μ1 < μ2

Complete the parenthesis:
-6 + 15w = 9w + 66
Switch the numbers and group them with like terms;
15w - 9w = 66 + 6

A 40 g ball of yarn is 125 m long. What is the mass of a ball of the same yarn that is 2 km long?
Answer:
640g
Step-by-step explanation:
1000m=1km so 125m times x= 2km x is 16 so we multiply 16 by 40 to get 640 g
The mass of 2 km long yarn ball is 640.
What is mass?A measure of how much matter is in an object. This gold bar is quite small but has a mass of 1 kilogram (about 2.2 pounds), so it contains a lot of matter.
Given
40 g ball of yarn is 125 m long
To find mass for 2 km = 2000 m long yarn
[tex]\frac{40}{125} \ 2000[/tex] = [tex]\frac{80000}{125}[/tex] = 640g
Hence, The mass of 2 km long yarn ball is 640.

The radius of the sphere is approximately 4.2 feet.
What is the volume of the sphere?To find the volume of a specific sphere, we need to know its radius. Once we have the radius, we can plug it into the formula and calculate the volume.
The formula for the volume of a sphere is:
V = (4/3) x π x r^3
where V is the volume of the sphere, r is its radius, and π is a mathematical constant approximately equal to 3.14.
We are given the volume of the sphere, so we can plug it into the formula and solve for the radius:
384 = (4/3) x π x r^3
Dividing both sides by (4/3) x π, we get:
r³ = 384 / ((4/3) x π)
r³ = 72.825
Taking the cube root of both sides, we get:
r ≈ 4.243
The radius of the sphere is approximately 4.2 feet.

Point m is located at 4,-2 what is located 2 units for point m
Answer:
None
Step-by-step explanation:
Given
[tex]m = (4,-2)[/tex]
Required
Point 2 units from m
There are 4 possible points 2 units from m and they are:
[tex]m' = (4+2,-2) = (6,-2)[/tex]
[tex]m" = (4,-2+2) = (4,0)[/tex]
[tex]m'''= (4-2,-2) = (2,-2)[/tex]
[tex]m'''' = (4,-2-2) = (4,-4)[/tex]
From the graph, we have:
[tex]A = (4,2)[/tex]
[tex]B = (-4,2)[/tex]
[tex]C = (2,-3)[/tex]
None of the points is 2 units from m
Point m is located at (4,-2), then point C is located approximately 2 units from point m.
A point in a graph is its location denoted using x and y axis.
Given the following information:
Coordinates of point m=(4,-2)
Coordinates of point A=(4,2)
Coordinates of point B=(-4,2)
Coordinates of point C=(2,-3)
Formula used to find distance between two points say (x1,y1) and (x2,y2) is
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
D1 distance between m and A is
[tex]D_1=\sqrt{(4-4)^2+(2+2)^2}\\D_1=4[/tex]
D2 distance between m and B is
[tex]D_2=\sqrt{(-4-4)^2+(2+2)^2}\\D_2=4\sqrt5[/tex]
D3 distance between m and C is
[tex]D_3=\sqrt{(2-4)^2+(-3+2)^2}\\D_3=\sqrt5\\D_3=2.2\\[/tex]
D3 is approximately equivalent to 2 not exactly 2.
Thus, point C is approximately at 2 units from m.

Choose the polynomial written in standard form.
xy2 + 4x4y + 10x2
x4y2 + 4x3y + 10x
x4y2 + 4x3y5 + 10x2
x6y2 + 4x3y8 + 10x
Answer:
Standard form means that you write the terms by descending degree.
x^4y^2 + 4x^3y + 10x^2
The degree of the first term x^4y^2 is 4+2=6
The degree of the second term 4x^3y is 3+1=4
The degree of the third term 10x^2 is 2
The terms are written by descending degree. Therefore, polynomial x^4y^2 + 4x^3y + 10x^2 is written in standard form.

A formula for finding the perimeter of a rectangle is P=2L+2W. If you know the perimeter (P) and width (W) of a rectangle, which formula can you use to find the length (L)?
Step-by-step explanation:
→ P = 2L + 2W
→ P = 2(L + W)
→ P ÷ 2 = L + W
