Answer:
45 in
Step-by-step explanation:
This look like the branch of the basic pythagorean triplet.
3, 4, 5 is a fundamental triplet.
if you multiply all three numbers by 9, you will get:
27, 36, 45
X = 45 in
Hope this helps :)
 
        
             
        
        
        
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.
 
        
             
        
        
        
Answer:
I think 1/2
Step-by-step explanation:
Since there are 4 coins overall and 2 nickels, then the probabilty is 2/4
2/4 simplified is 1/2
(I've never been too good at probability so sorry if it is wrong)
Why do you need the answer so bad? Are you trying to get a pet?
 
        
             
        
        
        
Let n be the larger integer and n-2 be the smaller integer.
n² - (n - 2)² 
= n² - (n - 2)(n - 2)
= n² - (n² - 4n - 4)
= n² - n² + 4n + 4
= 4n + 4
= 4(n + 1)
No matter what value n is, it will always be a multiple of 4.
