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
Step-by-step explanation:
2⁵ˣ = 8ˣ⁺²
2⁵ˣ = (2³)ˣ⁺²
2⁵ˣ = 2³ˣ⁺⁶
5x = 3x + 6
2x = 6
x = 3
ANSWER
a=-2, b=3
EXPLANATION
The given equation is
Recall that:
We simplify the left hand side to get:
For this equation to be true, we must have:
-6a=12 and 2+b=5
This implies that,
a=-2 and b=3
Absolute value of -3 is three, and then it just regular -3 equals -3 so basically whenever you see at -3 in those brackets or any negative number it means absolute value which will always be it’s positive version That negative number
