The owners of an eyeglass store claim that they fill customers' orders, on average, in 60 minutes with a standard deviation of 15.9 minutes. based on a random sample of 40 orders, a reporter determines a mean order time of 63 minutes. let µ represent the average number of minutes to fill an order. what is the z-statistic?

the first answer is 1.19

the second answer is 1.65

Solution:

We are given:

μ=60

σ=15.9

n=40

Therefore, the z-statistic is 1.19

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

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =
