HEY! So, simply pick 2 exact yet random points on the line.

I picked :  (20,50) and (80,90)

Slope equation : y₂-y₁ / x₂-x₁

Plug in the numbers.

m = 90 - 50 / 80 - 20

Simplify.

m = 40/60

Simplify.

m = 4/6

Simplify.

m = 2/3

~Hope I helped!~

natita [175]

Answer:

D

Step-by-step explanation:

We calculate the z-score for each

Mathematically;

z-score = (x-mean)/SD

z1 = (1.9-2.1)/0.2 = -1

z2 = (2.3-2.1)/0.2 = 1

So the proportion we want to calculate is;

P(-1<x<1)

We use the standard score table for this ;

P(-1<x<1) = P(x<1) -P(x<-1) = 0.68269 which is approximately 68%
