Elementary school A has implemented an after-school sports program and the principal would like to know if the participants of the sports program are becoming more active in general, compared to students who are not participating in the program. So the principal collected data on overall physical activities throughout the week from a group of the sports program participants and a group of school A students not in the program. The most appropriate statistical test for data analysis would be:_______.
A. Paired-samples t test
B. Independent-samples t test
C. Pearson's correlation
D. One-sample t test
Answer:
B. Independent-samples t test
Step-by-step explanation:
The test here is to find out if the participants of the sports program are becoming more active in general when compared to students who are not participating in the program.
Now, this will involve taking sample from the two independent groups to determine if there is statistical evidence that one is more active than the other.
Thus, the best test to use in this case will be the Independent-samples t test

Very much need some help ASAP !!
Answer:
D
Step-by-step explanation:
It cannot be Option A because the values are halve and there is nothing to distribute to them to make the values equal.
It's not option C because if you distribute 2y to each term in the parenthesis
you get -4[tex]y^{5}[/tex] + 6y³ + 4y². But where is the 8y² and -2y?
While Option B is equivalent, you can factor it out more and find the common factor of -2 to distribute among them as shown in option D
It is option D because distributing the -2y to each term solves to
-4[tex]y^{5}[/tex] + 6y³ + 8y² -2y.

Please help. This is due soon. Ty 
Answer:
3 dollars and 9 cents.
Step-by-step explanation:
From the question given above, the following data were obtained:
Total amount = 20 dollars
Amount for gift A = 9 7/10 dollars
Amount for gift B = 6 2/5 dollars
Amount for gift C =?
The amount of money she has left for gift C can be obtained as follow:
A + B + C = 20
9 7/10 + 6 2/5 + C = 20
Change to improper fraction
97/10 + 32/5 + C = 20
(97 + 64)/10 + C = 20
161/10 + C = 20
Collect like terms
C = 20 – 161/10
C = (200 – 161)/10
C = 39/10
Change to mixed fraction
C = 3 9/10 dollars
C = 3.9
C = 3 dollars and 9 cents
Therefore, Kathy had 3 dollars and 9 cent for gift C
A pipeline is placed diagonally across a rectangular field that is 25yd wide and 30yd long. How long is the pipeline, to the nearest yard?
Answer:
the pipe is 39.1 yards long.
Step-by-step explanation:
you would use pythagorean theorem (a²+b²=c²). plug the 25 in to the a² and plug the 30 in to the b² and figure out c² (it would look something like this 25²+30²=c²). to do that you need to square the 25² and the 30². the 25² would turn out to be 625 and the 30² would be 900 you would add them and get 1525. then you would squareroot 1525(
[tex] \sqrt{1525} [/tex]
) and get 39.05 and round it up and get 39.1 yards. dont forget to put the mesurements down

Each side of a square is increasing at a rate of 5 cm/s. At what rate (in cm2/s) is the area of the square increasing when the area of the square is 49 cm2
Answer:
25 cm^2/sec
Step-by-step explanation:
I my understanding of the question. It doesn't matter what the area of the square is currently is, for example if the area is 25 cm^2, 36 cm^2 or 49cm^2, the rate will ALWAYS increase by rate squared.
rate(a) x rate(b) = rate(area) in this case rate(a) = rate(b)
(5 cm^2/s) (5 cm^2/s) = 25 cm^2/s
Members of a baseball team raised $1479.25 to go to a tournament. They rented a bus
for $800.50 and budgeted $45.25 per player for meals. Write and solve an equation
which can be used to determine p, the number of players the team can bring to the
tournament.
PLEASE HELP FAST ITS FOR A TEST
Answer:
The equation is: [tex]800.5 + 45.25p \leq 1479.25[/tex]
The team can bring at most 15 players to the tournament.
Step-by-step explanation:
They rented a bus for $800.50 and budgeted $45.25 per player for meals.
This means that the cost for bringing p players is given by:
[tex]C(p) = 800.5 + 45.25p[/tex]
Members of a baseball team raised $1479.25 to go to a tournament.
This means that:
[tex]C(p) \leq 1479.25[/tex]
So
[tex]800.5 + 45.25p \leq 1479.25[/tex]
[tex]45.25p \leq 1479.25 - 800.5[/tex]
[tex]p \leq \frac{1479.25 - 800.5}{45.25}[/tex]
[tex]p \leq 15[/tex]
The team can bring at most 15 players to the tournament.

A number is twice the other number. The sum of four times the smaller number and three times the larger number is 10. Find the numbers.
Please teach me how to do this. I'll give 90 points.
Answer:
1 and 2
Step-by-step explanation:
Let the first number be x
Let the other number be y
x = 2y.....eqn 1
From eqn 1, the smaller number is y while the bigger number is x.
3x + 4y = 10.... eqn 2
Substitute x = 2y into eqn 2
3(2y) + 4y = 10
6y + 4y = 10
10y = 10
Divide both sides by 10
y = 10/10
y = 1
Substitute y= 1 into eqn 1
x = 2y
x = 2(1)
x = 2
The length of a rectangle is 10 cm, which is 1/3 of it's perimeter. Evaluate its perimeter
Answer:
Perimeter = 30 cm
Step-by-step explanation:
10 cm x 3 = 30 cm
the required perimeter of the given rectangle is 30 cm.
What is the perimeter?Perimeter is the measure of the figure on its circumference.
What is a rectangle?The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.
Here,
The length of a rectangle is 10 cm, which is 1/3 of it's perimeter.
Length = 1/3 of perimeter
10 = 1/3 perimeter
perimeter = 3 × 10
perimeter = 30 cm
Thus, the required perimeter of the given rectangle is 30 cm.
