Answer:

Option B: Paired sample t-test, since there is a "before 20 push ups" and "after 20 push up " score for each participant.

Step-by-step explanation:

In this question, we have a case where each participant undergoes different exercises to see differences before and after 20 push ups.

Now, it's obvious that the same condition applies to all participants i.e. differences before and after 20 push ups.

Thus, this will be a case of paired sample t-test or dependent t test because conditions for all participants in both tests are dependent or same.

So, the only option that corresponds with my explanation to use paired sample is option B

There are 32 point guards and 50 posts In Leo's basketball league. Leo must include all players on a team and wants each team to
Fantom [35]

The greatest number of teams Leo can create is 2

<em><u>Solution:</u></em>

Given that,

There are 32 point guards and 50 posts In Leo's basketball league

From given,

Number of point guards = 32

Number of posts = 50

Leo must include all players on a team and wants each team to have the same number of point guards and the same number of posts

To find the greatest number of teams Leo can create, we should find the greatest common factor of 32 and 50

When we find all the factors of two or more numbers, and some factors are the same, then the largest of those common factors is the Greatest Common Factor

<em><u>Greatest Common Factor of 32 and 50:</u></em>

The factors of 32 are: 1, 2, 4, 8, 16, 32

The factors of 50 are: 1, 2, 5, 10, 25, 50

Then the greatest common factor is 2

Thus the greatest number of teams Leo can create is 2

A circular running track is 1/4 mile long. Jamie runs on this track, completing each lap in 1/20 of an hour. What is Jamie’s run
Grace [21]

Answer: The running speed of Elena is 5 miles/hour and this can be determined by using the formula of speed.

Step-by-step explanation:

A circular running track 1/4 is a mile long.

Elena runs on this track, completing each lap in 1/20 of an hour.

Speed formula is used to determine the speed of Elena. The formula of speed is given by:

   ----- (1)

where S is the speed, D is the distance and T is the time taken by Elena to run a circle.

Now, put the value of distance D and time T in the equation (1).

Speed = 5 miles/hour

Therefore, the running speed of Elena is 5 miles/hour.

Order of Operation pls help I'll mark u Brainly<br>Sorry if it's a lot.​
KonstantinChe [14]

Okay, I got you...

2) 2

3) 6

4) 33

5) 5

6) 19

No. (12+6)/2=9

and 12+6/2=15

This happens because in order of operations parentheses come first, so you would do that and get 18. Then you would divide 18 by 2 and get 9.

On the second one you would do division first (6/2) and get three, the you would add 12 and end up with 15.

Hope this helps :)
