Answer: B) 45%
<u>Step-by-step explanation:</u>
There are 20 measurements that are 170 cm or greater.
There are a total of 44 measurements.
Answer:
2
Step-by-step explanation:
Because the people were randomly assigned to one of the two groups, there is a randomness to both groups making them the same. The group that doesn't get the cream is a control group so any differences observed between the control and the group being tested would be due to the cream.
P= 2πr
d= 2ft
P= 2×3.14
P= 6.28
1km= 3,280ft / 2km= 6560ft
6560÷6.28=1044.58 revolutions

Answer:
the probability is 0.28
Step-by-step explanation:
using Bayes's theorem
P(A|B)=P(A∩B)/P(B)
where
P(A∩B) = probability that events A and B happen
P(A|B) = probability that event A happen if B already happened
P(B)= probability of event B
therefore
P(A∩B)=P(A|B)*P(B)
if event A= selection of a student that lives in a dormitory and event B = selection of a freshmen student
P(A|B) = 0.8 (live in a dormitory knowing that is a freshmen student )
P(B) = 0.35 (freshmen student)
P(A∩B)=P(A|B)*P(B) = 0.8* 0.35 =0.28
