If the MAD for a forecast is 3.2, we can say that a. The forecast is 3.2 units too high on the average b. The forecast is 3.2 un
Rudik [331]

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

mixer [17]

we are given

In A 4 year period, About 80,000 acres of coastal wetlands in United States are lost each year.

so, total area =80000 acres

total time = 4 years

now, we can use formula

total change in wetlands = ( total area)/(total time)

now, we can plug values

total change in wetlands is

=\frac{80000}{4} acre/year

=20000 acre/year................Answer

Write an equation for the translation of y = |x|. 13 units down
olga55 [171]
The idea for transitions for an equation like this is
y = m|x - h| + k
where m = slope
h = how much left or right (note the negative)
k = how much up or down

moving 13 down would mean
k = -13

so
y = |x| - 13
D. would be your answer
