Circumference = 2 * pi * r, where r is the radius
For this circle, the circumference is 11pi, so 11pi=2*pi*radius. Divide both sides by 2pi and you get r is = to 5.5 inches.
Area of a circle is pi*r^2. Since we just saw that r = 5.5 inches, the circle has an area of 5.5 inches * 5.5 inches * pi or 30.25 pi inches squared.
Answer:
Step-by-step explanation:
<u>Answer:</u>
<u>Null hypothesis: Policy B remains more effective than policy A.</u>
<u>Alternate hypothesis: Policy A is more effective than policy B.</u>
<u>Step-by-step explanation:</u>
Remember, a hypothesis is a usually tentative (temporary until tested) assumption about two variables– independent and the dependent variable.
We have two types of hypothesis errors:
1. A type I error occurs when the null hypothesis (H0) is wrongly rejected.
That is, rejecting the assumption that policy B remains more effective than policy A when it is <em>actually true.</em>
2. A type II error occurs when the null hypothesis H0, is not rejected when it is actually false. That is, accepting the assumption that policy B remains more effective than policy A when it is <em>actually false.</em>
5+3 = 8
8 is 100%
3/8 = 37.5%
I feel like I might be wrong haha sorry if I am
Answer:
Step-by-step explanation:
Using the formula for calculating simple interest
SI = principal × rate × time/100
Given
Principal = $8750
Rate = 9.75%
Time = 2years
Substitute
Interest = 8750×9.75×2/100
Interest = 87.59×19.5
Interest = 1,706.25
Hence the finance charge to the nearest whole dollar is $1706
