Approximately 8 out of every 25 families in the united states own dogs. if you asked 90 families, about how many of them would you expect to own dogs?

28.8

Step-by-step explanation

8/25 families own dogs.

8/25  *  90 = 720/25 = 28.8

What do you do with the 0.8? I would say that since this is a statistic, you leave it for 2 reasons.

I know it is impossible to have 0.8 families, but it will have more significance as the sample approaches the general population. According to the census taken in 2017, there are 126.22 million households in the United states. Written in expanded form, that would be 126,220,000 families.

If you take that as your base and use 8/25 as the number with dogs, you come to 8/25 * 126,220,000 = 1009760000/25 = 40390400

The point I'm trying to make is that the 0.8 we were concerned about, no longer exists.

what is the information provided?

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
