Only one number line exists. THE number line. numbers -1 through 1 show -1/3 and 1/3
Step 1: Multiply both 0.4 and 0.05 by 100 to get 40 and 5
Step 2:Divide 40 and 5
Your answer: 8
Hope that helps :)
Answer:
There is 95% confidence that the population proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is between 55.9% and 74.7%.
Step-by-step explanation:
We have to answer the population proportion for Vermont.
We can only do it by a confidence interval, as we only have information from a sample.
This sample, of size n=100, has a proportion p=0.653.
The degrees of freedom are:
We will calculate a 95% confidence interval, which for df=99 has a critical value of t of t=1.984.
The margin of error can be calculated as:
Then, the upper and lower bounds of the confidence interval are:
Then, we can say that there is 95% confidence that the population proportion of people from Vermont who exercised for at least 30 minutes a day 3 days a week is between 55.9% and 74.7%.
A = ((6 + 7 + 6) . 8)/2
A = 19 . 4
A = 76
Answer: 7*N - 12
Step-by-step explanation:
Let's break this so is easier to interpret.
"12 less than a number"
if we call the number as N, this is written as:
N - 12
and the complete sentence is:
"12 less than a number times 7"
So we must multiply our number, N, by 7.
Then the expression is:
7*N - 12
