Well, al you have to do is find the least common multiple of members and non-members.
members:9.50
non-members:14.75
is $126
Using a confidence interval, we have that:
a) The range is from 48.8% to 51.2%.
b) Between 125,000 and 131,000 adults are registered organ donors.
<h3>What is a confidence interval?</h3>
A confidence interval is given by the <u>estimate plus/minus the margin of error</u>.
For this problem, we have that:
- The margin of error is of 1.2%.
The bounds of the range are given as follows:
Hence the range is from 48.8% to 51.2%.
<h3>What are the total numbers?</h3>
We have to find <u>48.8% and 51.2% of 255,200,373</u>, hence:
- 0.488 x 255,200,373 = 124,537,782.
- 0.512 x 255,200,373 = 130,662,591.
Rounded to hundredth thousand, between 125,000 and 131,000 adults are registered organ donors.

Answer:
Purchase Price = $150 and Total Price = $162
Step-by-step explanation:
Purchase price = Tax Amount / Tax Percentage (as decimal)
Purchase Price = $12 / .08
Purchase Price = $150
Total Price = Purchase Price + Tax
Total Price = 150 + 12 = $162
I hope this helps!

If the ratio of the dimensions is 4:7 and the shorter dimension is 10ft, we know that the 10ft corresponds to the 4 in this scenario. We can set up the equation as follows:
You have to multiply by 2.5 to get from 4 to 10. And since we want to make sure we are maintaining the ratio, we have to multiply the denominator, 7, by 2.5 as well.
This means your shorter side has a length of 10ft and your longer side has a length of 17.5ft.
AREA
The formula for the area of a rectangle is:
So we can plug our dimensions into the formula:
So 175 is our area. But we can't forget about units! Since this is area and we multiplied our units together, our units would be squared. That means our answer is <u>175 square feet</u>.
PERIMETER
The formula for the perimeter of a rectangle is:
We can plug our dimensions into the formula:
So 55 is our perimeter. Of course, we can't forget about our units. Because this is perimeter, we only added our units together, so they don't change. That means our answer is <u>55 feet</u>.
The answer is 5 to this expression
