The next step Nolan should take is to find the average of the distances from the mean.
<h3>What is meant by mean absolute deviation?</h3>
A measure of variance in a data set is the mean absolute deviation. We may determine how "spread out" the values in a data collection are by looking at the mean absolute deviation.
The steps to find mean absolute deviation are:
- Calculate the mean of the data set
- Calculate the value of distance between the mean and each point in the data set.
- Find the average of the distances from the mean.
Hence, The next step Nolan should take is to find the average of the distances from the mean.

So, we are given the speed in mi/min. We want to convert this to mi/hr. We can do this through cross multiplication.
(11 miles/1min) * (60min/hr) = 660 mi/hr
Now, we need to find the total distance flown:
TD= 6 trips*(500 miles/1 trip) = 3,000 mi
Lastly, we find total time using our converted speed and total distance.
speed = (total distance (in miles))/(total time (in hours))
660mi/hr= 3000mi / t
660t=3000
t=3000/660
t= 4.54 hrs
Answer: The plane will fly a total of about 4 and a half hours.
Substitute on equation 2, y = -4x + 7. so equation 1 becomes 2x - (-4x + 7) = 6x - 7 = 5. 6x = 12, so x = 2. from above, y = -4x+7 = -4(2) + 7 = -1
