Answer:
Step-by-step explanation:
Given that the housing market has recovered slowly from the economic crisis of 2008. Recently, in one large community, realtors randomly sampled 38 bids from potential buyers to estimate the average loss in home value.
s = sample std deviation = 3000
Sample mean = 9379
Sample size n = 38
df = 37
Std error of sample mean = 
confidence interval 95% = Mean ± t critical * std error
=Mean ±1.687*486.66 = Mean ±821.003
=(8557.997, 10200.003)
a) If std deviation changes to 9000 instead of 3000, margin of error becomes 3 times
Hence 2463.008
b) The more the std deviation the more the width of confidence interval.
In first diameter=8,In second diameter=2/3,
Answer:
v = 16.
Step-by-step explanation:
This is one of the equations of motion when acceleration is constant.
v = 6 + 2*5
= 16.
Answer:
12 fiction books.
Step-by-step explanation:
Let b represent number of non-fiction books.
We have been given that in the library at Lenape elementary school, there are 3/8 as many fiction books as there are nonfiction books. So number of fiction books would be 
.
We are also told that there are 44 books in school library. We can represent this information in an equation as:
Let us solve for x.
Therefore, there are 32 non fiction books in the library.
Number of fiction books would be 
Therefore, there are 12 fiction books in the library.
