You do 168+21=189 then you work out what 189 is as % so your answer =18900%
Step 1:
x² + 4x = 192
Step 2:
Take x common:
x ( x + 4) = 192
Length is x and width is x+4
Step 3:
x² + 4x - 192 = 0
Step 4:
x² + 16x - 12x - 192 = 0
x(x+16) - 12(x+16) = 0
(x-12)(x+16) = 0
⇒ x=12, x=-16
Because the length can't be -16, the length is 12.
Mean absolute deviation is the average of the sum of all deviations of the terms from the average of the terms...
mean=(5+9+9+11+16)/5=10
mad=[(10-5)+(10-9)+(10-9)+(11-10)+(16-10)]/5=2.8
Answer:
Use this graph of f to find f (2). Solution : By comparing the given question f (2) with f (x), we come to know that the value of x is 2, that is input.
