Answer:
The forecast is accurate within plus or minus 3.2 units
Step-by-step explanation:
Mean Absolute Deviation is a statistical measure of dispersion from forecast. It measures accuracy level of predicted forecast, by averaging the difference between absolute value of each error from forecasted value.
MAD for a forecast states that : Forecast is accurate within the expected range variation of Mean Absolute Deviation.
So : If the MAD for a forecast is 3.2, we can say that - The forecast is accurate within plus or minus 3.2 units
By changing the number into a decimal, and then moving the decimal twice to the right.
Given:
The inequality is
To find:
The solution set for the given inequality.
Solution:
We have,
Divide both sides by 3.
It can be written as
Subtracting 4 from each side, we get
The solution set of the given inequality is (-5,-3).
Therefore, the correct option is A.
we are given with an isosceles triangle with two congruent sides equal to 70 inches and an angle of 36 degrees in between the sides. We are asked for the area of the triangle. The formula is A = 0.5 * ab sin theta where a and b are the sides. The area is equal to 1440. 07 in2.
It is 0.0133
unless it is 1050 divided by 14 witch is
75
