The standard deviation and the mean of 16 values are 15.6 and 20.5. What is the coefficient of variation ?

CV = coefficient of variation = 0.761

Step-by-step explanation:

The coefficient of variation is defined as the standard deviation divided by the mean of a population, which in this case,

standard deviation = 15.6

mean = 20.5

CV = coefficient of variation = 15.6/20.5 = 0.761

Note that if the 16 values form a sample (i.e. not the entire population), the above result is an estimate of the CV.

answer: 12

step-by-step explanation:

because yes

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
