Answer:

The area of B is 8 cm²

Step-by-step explanation:

From the diagram, we can tell that the scale factor is 2 because the length of A is 6 cm and the length of B is 12 cm so the scale factor is 2. Since diagram A's area is 4 cm², all we need to do is multiply the diagram A's area by 2. That gives diagram B's area which is 8 cm²

Suppose the heights of the members of a population follow a normal distribution. If the mean height of the population is 68 inches and the standard deviation is 4 inches, 99.7% of the population will have a height within which of the following ranges?A. 56 inches to 80 inches
B. 60 inches to 76 inches
C. 64 inches to 72 inches
D. 52 inches to 84 inches

Answers

If the mean height of the population is 68 inches and the standard deviation is 4 inches, 99.7% of the population will have a height within ranges of; 52 inches to 84 inches.

What do you mean by standard deviation?

In statistics, Standard deviation is a measure of the variation of a set of values.

σ = standard deviation of population

N = number of observation of population

X = mean

μ = population mean

We know that at 99.7% the measurements would be within 2 standard deviations of the mean.

Mean of 68 inches

Standard Deviation of 4

The lower range = 68– 4(4)= 52 inches

The upper range = 68+ 4(4) = 84 inches

Thus, the option (D) 52 inches to 84 inches is correct after using the empirical Rule.
