Answer: Aquaman swims at the rate of 140.47m/min
The rate of water drain is 73.81m/min
Step-by-step explanation: Let A be the rate at which Aquaman swims.
Let W be the rate at which the water drains
3(A - W)= 200 ......equation (1)
0.7(A +W)=150 ..... equation (2)
3A -3W = 200 .....equation 3
0.7A + 0.7W = 150 ..eq4
Multiply eq 3 by 7 and eq 4 by -30
21A - 21W = 1400
-21A + 21W = -4500
Subtracting both equation from each other, you get
-42W = -3100
W = 3100/42
W = 73.81m/min
Put 73.81 for W in equation 1
3A - 3(73.81) = 200
3A - 221.43 = 200
A =421.43/3
A= 140.47m/min
The answer is 13
25/100 X 80/1
25/10 X 8/1
25 X 8 = 200
200 divided by 10 is 20
20/100 X 65/1
20 X 65= 1,300
1,300 divided by 100 is 13
I made them into fractions.

Answer:
The type of error that the sociologist has made when he fails to reject the null hypothesis when it is false (and thus should have rejected it) is a:
c) Type II error.
Step-by-step explanation:
In Statistics, Type II error is made when the null hypothesis is accepted when it is not true (false). The sociologist should have rejected the null hypothesis, but he fails to reject it. He has, therefore, made a Type II error. It is also called a "false negative." On the other hand, a Type I error is committed when the sociologist rejects the null hypothesis when he should have accepted it. A Type I error is also called a "false positive."
