Aset of data with a mean of 45 and a standard deviation of 8.3 is normally distributed. find the value that is –1 standard deviation away from the mean.

One standard deviation below the mean is 36.7

One standard deviation above to mean is 53.3

Idk which one your looking for

36.7

Step-by-step explanation:

If the value is −1 standard deviation from the mean, the z-score is −1.

−1−8.336.7===x1−458.3x1−45x1

The value 36.7 is −1 standard deviation from the mean.

answer:

c. the third graph

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
