b. x = –5

c. x = –1

d. x = 2

Answer:

No. You can't squirm out of it that easily ! Sorry.

The absolute value of a number is its size without a plus or minus.

So you don't need to be good with plus and minus to work absolute values.

The statement says "the absolute value of 'x' is less than 3".

Let's test each choice and see if it works:

a). x = -6. The absolute value of -6 is 6. Is that less than 3 ? No.

b). x = -5. The absolute value of -5 is 5. Is that less then 3 ? No.

c). x = -1. The absolute value of -1 is 1. Is that less than 3 ? Yes.

d). x = 2. The absolute value of 2 is 2. Is that less than 3 ? Yes.

Do you see ? You don't need to be Einstein or a math whiz

to answer this one.

You're just giving up because people say that girls can't do math,

and instead of telling them where to stick it, you bought into it.

A sample of households in a community is selected at random from the telephone directory. In this community, 2% of households have no telephone, 14% have only cell phones, and another 25% have unlisted telephone numbers. The sample will certainly suffer from A. nonresponse.

B. false responses.

C. undercoverage.

D. None of the above.

Answer:

c) Undercoverage

Step-by-step explanation:

We say that a sample has undercoverage when some members of it have zero chance of being selected for the sample.

In this particular example, the sample will be selected from the telephone directory, however, 41% ( 25 + 14 + 2) of the people who live in this community are not listed in the telephone directory, therefore, they have zero chance of being selected.

How do I solve 12-3(x-5)=21

12-3(x-5)=21

Distribute

12-3x+15=21

Combine like terms

27-3x=21

Subtract 27 from both sides

-3x= -6

Divide both sides by -3

x=2

Final answer: x=2

Distribute

12-3x+15=21

Combine like terms

27-3x=21

Subtract 27 from both sides

-3x= -6

Divide both sides by -3

x=2

Final answer: x=2
