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?

Answer:
(-6/10)+(2/8)
Step-by-step explanation:
Adding -7/10 and 1/10 gives us -6/10
Adding 2/8 and -4/8 gives us 2/8
Hi there!
From what I know, when you multiply one number in a ratio, you must also multiply the other number by the same number. This allows for the ratio to stay the same, thus keeping it correct. If both terms were not multiplied by n, the ratio would no longer be the correct ratio.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
I'm assuming that the figure formed in this problem is a right angle. Thus, we need to use the Pythagorean theorem to get the distance or the hypotenuse.
Length = 20 meters
Height = 16 meters
a² + b² = c²
(20m)² + (16m)² = c²
400m² + 256m² = c²
656m² = c²
√656m² = √c²
25.61 m = c
The distance is 25.61 meters.
