Option D
The trip lasts for 
<em><u>Solution:</u></em>
<em><u>Mr Patel is planning to drive 325 miles</u></em>
Average speed is 65 mph
He will stop one hour for lunch and take a 15 min rest break
Let us first find the time taken
Thus he covers 325 miles in 5 hours
Also, given that, he will stop one hour for lunch and take a 15 min rest break
<em><u>Therefore, total time taken for trip is:</u></em>
Total time = 5 hours + 1 hour + 15 minutes
Total time = 6 hours 15 minutes
We know that,
1 hour = 60 minutes
Therefore,
Thus the trip lasts for
Answer:
B
Step-by-step explanation:
Because when you add negitives to negitives it then becomes a positive for the y intercept.
Answer: 3 divided by 2 = 1.50
1.50×10=15
Step-by-step explanation:
Answer:
a) The 95% confidence interval to estimate the average fee for the population is between $11.65 and $12.79
b) $0.57
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
So the answer for b) is $0.57.
The lower end of the interval is the sample mean subtracted by M. So it is 12.22 - 0.57 = $11.65
The upper end of the interval is the sample mean added to M. So it is 12.22 + 0.57 = $12.79
The 95% confidence interval to estimate the average fee for the population is between $11.65 and $12.79
Answer:
It's 144 units^2
Step-by-step explanation:
You have to take your 3/2 and square it, turning it to 9/4 and multiply that by 64, which gives you 144.
