Answer:
<h2>In this case,the answer would be option d) given in the answer choices or options or A two-sample t-test for a difference between population means.</h2>
Step-by-step explanation:
- In Statistics,a two sample test is generally used to examine or compare two different population means with the main objective to verify whether the population means are equal or otherwise.
- The two sample t-test basically involves the hypothesis testing to determine or verify the equality between two concerned population means.
- In this case,the two different populations of raccoons are given and the equality of the mean sample weights of the two distinct populations can be determined or evaluated by employing the hypothesis testing method under a two sample t test for measuring difference in two population means.

Answer:
- $1000
- $600
- $250
Step-by-step explanation:
Let t represent the third-place prize value. Then the first place prize has a value of 2t+500, and the second-place prize is 2t+100. The total value of the three prizes is ...
t +(2t+500) +(2t+100) = 1850
5t +600 = 1850
5t = 1250
t = 250 . . . . . . . . . . . third place prize
2t +500 = 1000 . . . . first place prize
1000 -400 = 600 . . .second place prize
The prizes for 1st, 2nd, and 3rd places are $1000, $600, and $250, respectively.
Answer:
Option H
Step-by-step explanation:
Option F
If two lines are cut by a transversal so that a pair of corresponding angles are congruent, then the lines are parallel.
True.
Option G
If two lines are cut by a transversal so that a pair of alternate exterior angles are congruent, then the lines are parallel.
True
Option H
If two line are cut by a transversal so that a pair of vertical angles are congruent, then the lines are parallel.
Since, vertical angles don't prove the lines cut by a transversal are parallel.
So the statement is False.
Option J
If two lines are are cut by a transversal so that a pair of same side interior angles are supplementary, then the lines are parallel.
True.

Answer:
75 minutes
Step-by-step explanation:
In this question, we are asked to calculate the time it will take a smaller hose out of two hoses to fill a swimming pool by itself.
Firstly, let’s say the volume of the swimming pool to fill is Xm^3.
Hence for both, the rate of filling is x/30 m^3/minutes. For the larger hose, rate will be x/50 m^3/minutes. For the larger hose, let the time taken be z minutes. It’s rate will be x/z m^3/minute.
Mathematically, adding both rates together give the rate of both at the same time. This means;
X/30 = x/50 + x/z
X/z = x/30 - c/50
x/z = 20/1500
x/z = 1/75
z = x/75
This means the time that it will take the smaller hose will be 75 minutes
