The estimate is twelve because five goes into sixty roughly twelve times.
3x + 5

7
Subtract 5 to both sides so
3x + 5 - 5

7 - 5
3x

2
Divide 3 to both sides
3x

2

Cancel out the 3 on the left side,

Answer:

By definition, the geometric mean of n numbers is the n-th root of the product of the numbers.
We are given two numbers: 21 and 54.
Their product is 21*54 = 1134
Because we have two numbers, their geometric mean is
√(1134) = 33.675
Answer: 33.675
Answer:
A) The probability is 0.95 that the percent of adults living in the United States who are satisfied with their health care plans is between 63.6% and 68.4%.
Step-by-step explanation:
A polling agency reported that 66 percent of adults living in the United States were satisfied with their health care plans. The estimate was taken from a random sample of 1,542 adults living in the United States, and the 95 percent confidence interval for the population proportion was calculated as (0.636, 0.684).
This means that we are 95% sure that the true proportion of adults living in the United States who were satisfied with their health care plans is between 0.636 and 0.684.
So the correct answer is:
A) The probability is 0.95 that the percent of adults living in the United States who are satisfied with their health care plans is between 63.6% and 68.4%.
