3x = 24
x = 24/3
x = 8
Answer:
0.0417
Step-by-step explanation:
Given the following;
p = 0.7, n=121
The sampling distribution of sample proportion will be approximately normal with mean
\mu_{\hat{p}}=p=0.7
and standard deviation
\sigma_{\hat{p}}=\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.7\cdot 0.2}{121}}=0.0417

Answer:
96
Step-by-step explanation:
8x6=48

You can find the perimeter of a circle by using the radius.
circumference = 2

Circumference = 2

circumference = 24 pi
Since you are only trying to find half of the circle you would divide your answer by 2
24pi / 2 = 12 pi
12 pi = 37.68
The answer is B. 37.7
