The area of a circle is pi • radius^2
so
3.4^2 • 3.14 = 36.3
Good luck! The answer is C!
8-2 and then 3 divided by 6 which will give you 0.5 so x=0.5
Answer:
-10 points
Step-by-step explanation:
A game show awards 30 points for each correct answer and deducts 50 points for each in correct answer. A contestant answers 2 questions incorrectly and 3 questions correctly. What is his final score?
Let us say Initial number of points = 0
Hence,
He answers 2 incorrectly = 0 - 50 - 50
= -100
He answers 3 correctly =-100 + 30 + 30 + 30
His final score = -100 + 30 + 30 + 30
= -10 points
Answer:
The 95% margin of error for this estimate is 0.0274 = 2.74 percentage points.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
72% of Americans said that they had at least one credit card
This means that 
Give the 95% margin of error for this estimate.


The 95% margin of error for this estimate is 0.0274 = 2.74 percentage points.
