I think it would be 8 miles: it would have been 2 hours, so 4 * 2 is 8 miles.
:) Hope this helps!
Answer:
90% confidence interval: (70.41,86.89)
Step-by-step explanation:
We are given the following in the question:
Point estimate = 78.65
Margin of error, E = 8.24
Confidence level = 90%
Significance level = 10%
Formula:

Putting the values, we get,


(70.41,86.89) is the required 90% confidence interval.
The correct answer is 0.125. Each outcome is out of 8 possible outcomes. 1/8 = 0.125 . Therefore, 0.125 is your answer.
Y' = -2x+a
0 = -2(3)+a
6=a
8=-(3)^2 +(3)(6)+b
b=-1
Square root of 3 is 1.732
