A recent study sought to determine if exercising after studying for an exam may help retain information. The 150 student volunteers that participated in the study were randomly assigned to three groups. All students were given a picture memory task that they studied for 15 minutes. After studying, one of the groups was instructed to exercise for 30 minutes immediately after studying. A second group was instructed to wait 1 hour after studying and then exercise for 30 minutes. The third group was instructed to not exercise after studying. The next day all 150 student volunteers were given a test to determine how well they could remember what they studied. Here are the results:

Answer:
The correct answer is (A).
Step-by-step explanation:
Because the data came from 3 groups in a randomized experiment, the appropriate test is a chi-square test for homogeneity.
The area of a circle is 4π in². What is the circumference, in inches? Express your answer in terms of π.
Answers
Answer:
C = 4π in
Step-by-step explanation:
We require to find the radius r of the circle
Given the area is 4π , then
πr² = 4π ( divide both sides by π )
r² = 4 ( take the square root of both sides )
r = [tex]\sqrt{4}[/tex] = 2
Then
C = 2πr = 2π × 2 = 4π inches
Answer:
4π in
Step-by-step explanation:
The formula for area is πr². We will work backwards from 4π. First, I will do √4 so I can find r.
√4 = 2
Now, I know that r = 2. Next, I will substitute r into the circumference formula which is 2πr.
2π(2) - I know r is 2 from my previous set.
Now, I will simplify.
2 · 2 π = 4π
Since the question is asking in terms of π, I will not simplify all the way, and leave pi as is.

The right angle triangle must obeys the Pythagorean theorem.
c² = a² + b²
where
c = hypotenusea and b are the other legs.Therefore, the sides that makes a right angle are as follows:
6, 8 , 10 : 6² + 8² = 10²

Shelly is given $300 to spend on jeans and sweaters.
Each pair of pants is $65, each sweater is $34, and she purchases seven pieces.
As per the given question, the required solution would be as:
She could buy three pairs of jeans and three sweaters since any more would be insufficient because three pairs of jeans and three sweaters would equal $297.
65 x 3 = 195
34 x 3 = 102

Consider the functions F(x)= x^2+9x and g(x)=1/x.
F(g(-1))is ? , and G(f(1/2))is ? .
Answers
Answer:
a). -8 b). 4/19
Step-by-step explanation:
F(x)= x²+9x g(x)=1/x.
g(-1) = 1/ - 1
= -1
f(-1) = x²+9x
= -1² + 9(-1)
= 1 - 9
= -8
G(f(1/2))
f(1/2) = x²+9x
= 1/2² + 9(1/2)
= 1/4 + 9/2
= 19/4
g (19/4) = 1/x
= 1/19/4
= 4/19
Answer:
1). -8 2). 4/19
Step-by-step explanation:
F(x)= x²+9x g(x)=1/x.
g(-1) = 1/ - 1
= -1
f(-1) = x²+9x
= -1² + 9(-1)
= 1 - 9
= -8
G(f(1/2))
f(1/2) = x²+9x
= 1/2² + 9(1/2)
= 1/4 + 9/2
= 19/4
g (19/4) = 1/x
= 1/19/4
= 4/19
