The ratio of the difference of the two means to Sidney’s mean absolute deviation is; 4/3.28
<h3>How to find the Mean Absolute Deviation?</h3>
From the given table, we see that;
Mean grade of Sidney = 82
Mean grade of Phil = 78.
Mean absolute deviation of Sidney = 3.28
Mean absolute deviation of Phil = 3.96.
The difference between the two means of Sidney and Phil = 82 - 78 = 4.
Thus, the ratio of the difference of the two means to Sidney’s mean absolute deviation is; 4/3.28
Complete Question is;
The means and mean absolute deviations of Sidney’s and Phil’s grades are shown in the table below. Means and Mean Absolute Deviations of Sidney’s and Phil’s Grades Sidney Phil Mean 82 78 Mean Absolute Deviation 3.28 3.96 Which expression represents the ratio of the difference of the two means to Sidney’s mean absolute deviation?

The answer is C, 288 yd and here is why. The formula for the surface area of a rectangular prism is 2(Lw+wh+Lh), with L being the length, w being the width, and h being the height. After that, you plug in your values 2(8(8)+5(8)+5(8)). Make sure you follow PEMDAS, aka The Order of Operations. Solve in the parenthesis first. Inside the parenthesis, it simplifies to 64+40+40, which simplifies to 64+80, which further reduces to 144. Now multiply 144 by 2, which gives you your final answer, 288.
