Several items in a store are on sale. Complete the table with the correct prices.
jarptica [38.1K]

Answer:

1. $48

2.$49

3.$91

4.$12

Step-by-step explanation:

For 1 and 2

To find the sale price, you find out how much is the percentage of the original price. Example :

(20/100)/60 = $12

So $12 is the discount

thus sales price will be $60-$12=$48

Same thing for no.2, find the amount of the percentage and subtract it from the original price

For 3 and 4

To find the original price

1. Subtract the percentage from 100%

2. Multiply the sales price by 100

3. Divide the ans from no.2 by ans from no.1

Example :

100%-40%=60%

$54.60×100=5460

$5460÷60%= $91 (original price)

Same thing for no.4

Hope this helps haha

A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten y
lyudmila [28]

Answer: $69811

Step-by-step explanation:

Given : A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten years, but with a smaller percentage of participants.

One of these surveys estimates with 90% confidence that the mean household income in the U.S. falls between $69,702 and $69,920.  (1)

We know that the confidence interval is given by :-

Point estimate of mean  ± Margin of error

From (1) , we have

Point estimate for mean  -Margin of error = $69,702   (2)

Point estimate for mean  +Margin of error = $69,920      (3)

Add (2) and (3), we get

2 (Point estimate for mean) = $139622

Divide both sides by 2, we get

Point estimate for mean=$ 69811

Therefore , the point estimate for mean U.S. household income. =  $ 69811

2.5(20+12)

20+12 is 32. 32 multiplied by  2.5 is 80.
