A standard deviation of 10 values is 8.19. You add 5 points to each score in the sample. The standard deviation for the new sample is:

8.19

Step-by-step explanation:

Adding 5 points to each score in the sample has no effect on the standard deviation. The standard deviation remains the same and constant.

Therefore, the standard deviation for the new sample is 8.19

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

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
