The answer will be Mean = 135 Variance = 62 and Standard Deviation = 8
<h3>What is the standard deviation? </h3>
Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.
Given that :
Proportion (p) = 54%
Sample size (n) = 250
Using Normal approximation :
Mean = np
Mean = 250 * 0.54 = 135
Variance = npq ; q = 1 - p = 1 - 0.54 = 0.46
Variance = (250 * 0.54 * 0.46) = 62.1 = 62
Standard deviation = √variance = √62.1
Standard deviation = 7.8803553 = 8

Answer:
2
Step-by-step explanation:
only made $9 so one cup is $3 so two cups equal $9
It is (3,3) because P will become A after the rotation which is answer C.
Answer: The answer is D
Step-by-step explanation:
If you read all the answers only D is true
Answer:
A = 3.14
Step-by-step explanation:
Area = π r^2
Circumference = 2π r
- A = C^2/4π
- 6.28^2/4•π ≈ 3.13841
