Step-by-step explanation:
Take the first derivative
Set the derivative equal to 0.
or
For any number less than -1, the derivative function will have a Positve number thus a Positve slope for f(x).
For any number, between -1 and 1, the derivative slope will have a negative , thus a negative slope.
Since we are going to Positve to negative slope, we have a local max at x=-1
Plug in -1 for x into the original function
So the local max is 2 and occurs at x=-1,
For any number greater than 1, we have a Positve number for the derivative function we have a Positve slope.
Since we are going to decreasing to increasing, we have minimum at x=1,
Plug in 1 for x into original function
So the local min occurs at -2, at x=1
Answer:
Step-by-step explanation:
total degrees of a line is 180
4x+20+60=180
4x=100
X=25
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.
