Your answer is D 18. The exact answer is 18.288.
No, he will not cover at least 8 miles because 120 yards times the 30 times he runs the circle equals 3,600 yards which converts to about 2 miles
Answer:
y = - x + 4
Step-by-step explanation:
The first step is to find the slope-intercept form, which is:
y=x-6.
Then, y=x+6
y=-x+4 should be the answer since it passes through the point (-1, 5)

See below for answers and explanations
Step-by-step explanation:
<u>Part A</u>
Assuming that conditions have been met for the interval, we use the formula 
where 
represents the sample mean, 
represents the critical value, 
represents the sample standard deviation, and 
is the sample size.
The critical value of for an 80% confidence level with degrees of freedom 
is equivalent to 
Thus, we can compute the confidence interval:
Therefore, we are 80% confident that the true mean age of all customers is between 30.17 and 35.11 years.
<u>Part B</u>
The margin of error is 
7/8 you have to make 1/4 into 2/8 and 2/8+5/8=7/8
