The student took 7 tests.
99+98+88+88+88+88+88 = 637
637/7 = 91
<span>6^3 + 5(4 − 2)
= </span><span>216 + 5(2)
</span><span>= 216 + 10
= 226
based on multiple choice options, 63 = 6^3
so answer is </span><span>c. 226</span>
If the mean value of the data set is 509. Then the mean absolute deviation (MAD) for the data set will be 51.5.
<h3>What is the mean absolute deviation?</h3>
It is the average distance between each data point and the mean.
The mean of the following data is 509.
{419, 450, 462, 499, 520, 521, 589, 612}
Then the mean absolute deviation (MAD) for the data set will be

We have
μ = 509
n = 8
Then
