Answer:

Chebyshev's theorem guarantees that we will find at least approximately 89 % of the choir members between 46 and 70 inches.

Step-by-step explanation:

Chebyshev's Theorem states that, in a sample:

75% of the measures are within 2 standard deviations of the mean

89% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 58

Standard deviation = 4

Between what two heights does Chebyshev's Theorem guarantee that we will find at least approximately 89 % of the choir members?

Within 3 standard deviations the mean, so from 3 standard deviations below the mean to 3 standard deviations above the mean.

3 standard deviations below the mean

58 - 3*4 = 46

3 standard deviations above the mean

58 + 3*4 = 70

Chebyshev's theorem guarantees that we will find at least approximately 89 % of the choir members between 46 and 70 inches.

Need ASAP answer because I don’t not understand

Hello there! The correct answer is B.

Note that in functions, x values cannot repeat. The points are given as (x, y) values, and you can see in the second option there are two -7s in the x values, making it not a function!
