Where x is the value, 4 is the mean, The formula for a z-score is z =
(x-0)
44
and o is the standard deviation.
A. True
B. False

False

   Z = x - μ /σ

Step-by-step explanation:

Explanation

The given mean of the Population= μ

Given the standard deviation of the Population(S.D) = σ

Let 'X' be the random variable in a normal distribution

Z-score

   Z = x - μ /σ

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
