Answer:
B
Step-by-step explanation:
Answer: he percentage of height of A is 85% and the percentage of height of B is 135% and it can be evaluated by using unitary method.
Step-by-step explanation:
he percentage of height of A is 85% and the percentage of height of B is 135% and it can be evaluated by using unitary method.
Given :
To ride on roller coaster you must be 40 inches tall.
Unitary method is used to find the percentage of height of A and percentage of height of B. Single unit is determined first in the unitary method and than multiply the single unit to find the necessary value.
Applying unitary method to determined the percentage of height of A.
Divide 34 by 40.
Multiply the above value by 100.
= 85%
Again applying unitary method to determined the percentage of height of B.
Divide 54 by 40.
Multiply the above value by 100.
= 135%
The percentage of height of A is 85% and the percentage of height of B is 135% and it can be evaluated by using unitary method.

Answer:
a. The empirical rule.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed(bell-shaped) random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
So the correct answer is:
a. The empirical rule.
