According to the United States Health and Human Services, the mean height for Americans is 1.757 meters for men and 1.618 meters for women. The standard deviation is 0.074 meters for men's height and 0.069 meters for women's height. Michelle’s height is 1.758 meters. What is her z-score?

Her z-score is 2.03.

Step-by-step explanation:

In a set with mean and standard deviation , the zscore of a measure X is given by:

Michelle’s height is 1.758 meters. What is her z-score?

Michelle's is a woman.

The average height of women is and the standard deviation is

This is Z when X = 1.758. So

Her z-score is 2.03.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
