Aset of data with a mean of 45 and a standard deviation of 8.3 is normally distributed. find the value that is +3 standard deviations away from the mean.

69.9

Step-by-step explanation:

If the value is +3 standard deviations from the mean, the z-score is 3.

324.969.9===x1−458.3x1−45x1

The value 69.9 is +3 standard deviations from the mean.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
