It's a rational number. 9 is a perfect square. What you have asked is written as -sqrt(9), which can be written as -sqrt(3*3) which is - 3. That's perfectly OK. What would not be OK is something like -sqrt(10) which is irrational because it cannot be represented as a fraction or a whole number or a repeating decimal or a decimal that terminates.

The negative square root of nine is neither rational or irrational.

The answer to this problem is 3i, which is an imaginary number. Imaginary numbers, by definition, are neither rational or irrational.

Robinâ€™s scores: 99, 108, 102, 107, 119 Mean = 107; MAD = 5. 2 Evelynâ€™s scores: 125, 137, 138, 145, 145 Mean = 138; MAD = 5.

The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean.

The MAD implies that Evelyn scores are more spread out than Robin scores.

The given parameters:

Robin scores = 99, 108, 102, 107 119
Mean of Robin score, = 107
Mean absolute deviation = 5.2
Evelyn scores = 125, 137, 138, 145
Mean of Evelyn score = 5.6

The mean absolute deviation (MAD), refers to the mean of the data's absolute deviations around the data's mean. It implies the absolute distance from the mean of the data set.

The absolute distance of Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.

Thus, we can conclude that Evelyn scores are more spread out than Robin scores.
