The mean, as a measure of location, would be inappropriate for which of the following? A. Ages of adults at a senior citizen center. B. Number of pages in textbooks on statistics. C. Incomes of lawyers. D. Marital status of college students at a university.

D. Marital status of college students at a university.

Step-by-step explanation:

The mean, as a measure, is appropriate when we are dealing with quantitative measures, that is, the measure that we are dealing with is a number.

In this question:

Options A(age), B(number of pages) and C(income) are all quantitative, so the mean is appropriate.

In Option D, the marital status is a qualitative measure(married, dating, single), so the mean is innapropriate, and this is the answer,

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
