34,590 because even if 0 engines are made, then 34,590 is still expected as a base price
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: Its 94.2
Step-by-step explanation:all you do to get the area is double 15 meaning 15 times 2 equal 30 times 3.14 equal 94.2 *that's crazy your in high school*
Answer:
B
Step-by-step explanation:
Recall that functions are defined only if for each value in the domain produces one and only one value in the range.
If we view the relations in the questions as x-y coordinates, this means that for every x-value, you can only have one y-value
Lets evaluate the options:
A) we can see that for x = -3, this gives 2 possible values for y i.e (-3,4) and (-3,8) (hence this is not a function)
C) we can see that for x = 3, this gives 2 possible values for y i.e (3,-8) and (3,8) (hence this is not a function)
D) we can see that for x = -3, this gives 2 possible values for y i.e (-3,4) and (-3,8) (hence this is not a function)
the only choice where this doesn't occur is choice B
