Answer:
Muscles Gym: 13.33
Energy Gym: 15.00
Step-by-step explanation:
Muscles Gym: You divide "40.00" by "3", which will then give you the answer of "13.33".
Energy Gym: You divide "93.00" by "6", which will then give you the answer of "15.50".
You then add the zero to show the proper number of cents after the decimal point.
I hope this helps!
Answer:
a) 0.23
b) The 95% confidence interval for the population proportion is (0.1717, 0.2883).
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
.
Point estimate
The point estimate is:

95% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The 95% confidence interval for the population proportion is (0.1717, 0.2883).
The answer is B. -3, 3
This is why:
3|3*3| = 27
3|9| = 27
3*9 = 27
The same will happen with -3 since this | means the distance from the number to zero and in this case it is 3 units til you reach zero. So the answer is B. 3, -3
Answer:
radius = 15 in.
circumference = 94.2 in.
Step-by-step explanation:
radius = diameter/2 = 30 in./2 = 15 in.
circumference = (pi)d = 3.14 * 30 in. = 94.2 in.
