First you find 80% of 90. Set up the proportion:
80 X
—— = —-
100 90
I’m simplifying the 80/100 so it’ll be easier to solve:
4 X
— = —-
5 90
Then cross multiply:
4(90) = 5x
360 = 5x
x = 72
So 80% of 90 is 72. (Or you could have multiplied 90 by 0.8 as a shortcut). Now you find 15% of 72. You can either multiply 72 by 0.15 or set up the proportion like this:
15 X
—— = —-
100 72
Cross multiply and solve. You should get 10.8

Probability = 1/16*100 = 6.25 %
Answer:
C
Step-by-step explanation:
Taking the equation for this we can see that A is using 8 to multiply. 8% = 0.08. But since the percent is increases it would be 1.08. So we can see that it cant be A, this applys for B as well. For D it says 1.8 which is close but that would be 80% not 8%. So now we can see that C is the answer.
Classify the two given samples as independent or dependent.
sample 1: the scores of 20 students who took the act
sample 2: the scores of 20 different students who took the sat
Solution: The two given samples are independent samples because in both the samples, the scores of one student will not affect the scores of other students.
Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations.
