Since the book store sold 30 books they also sold 3 bookmarks.
Answer: 3 bookmarks</span>
It’s is 997/1000. Just put the number over the highest decimal place
Answer:
C. Type I error
Step-by-step explanation:
Hello!
The hypothesis tested was:
H₀: μ = 7
H₁: μ > 7
The decision was taken: Reject the null hypothesis.
Reminder:
There are four decisions you can take when you make a hypothesis test.
1. Reject the null hypothesis when the hypothesis is false (This is a correct decision)
2. Reject the null hypothesis when the hypothesis is true (This decision is also known as Type I error)
3. Fail to reject the null hypothesis when the hypothesis is true (This is a correct decision)
4. Fail to reject the null hypothesis when the hypothesis is false (This decision is also known as Type II error)
Since they concluded, that the average process time vas greater than 7 days, when it was 7 days, they rejected the null hypothesis when it was true. This is a Type I error and its associated probability is α.
I hope it helps!
Answer:
Step-by-step explanation:
divide 34 get 17 then 17 x 17 and get 289 then multiply that by 3.14 then you will get 24501.42 that is the answer
Based on the dimensions of the regular pentagon, the approximate area can be found to be 342 cm².
<h3>How to solve for approximate area?</h3>
The area of the pentagon can be found by the formula:
= 5 x 1/2 x Length of pentagon x apothem of pentagon
The apothem is:
= √(12² - (14.1/2)²)
= 9.7
The approximate area of the pentagon is therefore:
= 5 x 1/2 x 14.1 x 9.7
= 342 cm²
