Step-by-step explanation:
Answer:
V = 523.6 yd³
Step-by-step explanation:
The equation for the volume of a sphere of radius r is
V = (4/3)πr³
and if we substitute 5 yds for r, we get
V = (4/3)*π*(5 yd)³, or
V = (4/3)·π·125 yd³, or approxomately
V = 523.6 yd³
We will call:
M=Mari
J=Jen
Initial equations:
M=2J
M+J=480
(the fact that they work 20 hours a week is not needed in this problem information)
Plug in:
2J+J=480
3J=480
J=160
Jen makes $160 a week.
Therefore:
M=2J
M=2(160)
M=320
Mari makes $320 per week
Jen makes $160 per week

Answer:
95% Confidence interval: (0.0429,0.0791)
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 679
Number of anonymous websites, x = 42

95% Confidence interval:


Putting the values, we get:

is the required confidence interval for proportion of all new websites that were anonymous.
