Answer:
scale factor is 2.5
Step-by-step explanation:
Notice that the original image is smaller than the scale drawing. Examine the ratios of the sizes:
Image/ Original :
height: 3.75 in / 1.5 in = 2.5
length: 5 in / 2 in = 2.5

Answer:
X = 40
Step-by-step explanation:
Original mean (µ) = 37
Original standard deviation (σ) = 6
New mean (µ) = 50
New standard deviation (σ) = 10
The z-score of an individual who had a score of X=55 in the new distribution is given by:

A z-score of 0.5, in the original distribution yields a score, X, of:

This individual’s score in the original distribution is X = 40
