The answer to your question is A. 1251cm
A = (1/2)base*height
Since this is an equilateral triangle each side is 34 inches, the altitude bisects the base into two 17 inch segments
There is now a right triangle with a base of 17 inches and a hypotenuse of 34 inches, so the pythagorean theorem (a^2 + b^2 = c^2) can be used
17^2 + b^2 = 34^2
or b^2 = 34^2 - 17^2
b^2 = 867 (take the square root of both sides)
b = 17
so the height of the equilateral triangle is 17
A = (1/2)(34)(17
)
A = 500.56 square inches
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:
- <em>Robin scores = 99, 108, 102, 107 119</em>
- <em>Mean of Robin score, = 107</em>
- <em>Mean absolute deviation = 5.2</em>
- <em>Evelyn scores = 125, 137, 138, 145</em>
- <em>Mean of Evelyn score = 5.6</em>
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.
