Answer:
D. X^2=49
Step-by-step explanation:
X= -4 or X=7
X^2=(-7)^2=49
or
X^2=(7)^2=49
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%.
Angles x, y, and z are 5s.
Angle x is a vertical angle to 5s, angles x and y are alternate interior angles so y is also 5s. And z is an alternate exterior angle to angle y.
I can't really figure out the number value of 5s with the given information.
