Find the mad (mean absolute deviation) 79%, 85%, 90%

The mean absolute deviation is the mean of the absolute values of the differences between the given numbers and their mean. The mean is

... (79+85+90)%/3 = 84 2/3%

so the deviations are

... -5 2/3%, +1/3%, 5 1/3%

and the mean of their absolute values is

... (5 2/3 + 1/3 + 5 1/3)%/3 = 3 7/9%

I find it convenient to let a calculator handle the tedious math.

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.
