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, 68% of the population will have a height within
which of the following ranges?
A. 64 inches to 72 inches
B. 56 inches to 80 inches
C. 60 inches to 76 inches
D. 52 inches to 84 inches

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

step-by-step explanation:

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
