Answer:
P(B) = 0.65
Step-by-step explanation:
The appropriate formula is ...
P(A or B) = P(A) +P(B) -P(A and B)
Then P(B) is ...
P(B) = P(A or B) +P(A and B) -P(A)
P(B) = 0.8 +0.15 -0.3
P(B) = 0.65
The answer is $14 because 65% of $40 is 26 and 40-26=14
Answer:
The sample proportion denoted
, is given by the formula
, where x is the number of individuals with a specified characteristic in a sample of n individuals.
When we want to estimate the real population proportion
we use as estimate the sample proportion, given by
. Where:
x is the number of individuals with a specified characteristic in a sample
n represent the sample size of individuals selected.
Step-by-step explanation:
For this case we can complete the phrase like this:

The answer for that is 34
C=pi*2*r
so c=3.14*2*18
so the circumference is 113.04
