Answer: (17.42, 20.78)
Step-by-step explanation:
As per given , we have
Sample size : n= 9
years
Population standard deviation is not given , so it follows t-distribution.
Sample standard deviation : s= 1.5 years
Confidence level : 99% or 0.99
Significance level :
Degree of freedom : df= 8 (∵df =n-1)
Critical value :
The 99% confidence interval for the population mean would be :-
Hence, the 99% confidence interval for the population mean is (17.42, 20.78) .
If you have 14 coins in your pocket and the amount of money you have in your pocket is 2.50, when only using nickels and quarters you would have:
5 Nickels=0.25
9 Quarters=2.25
0.25+2.25=$2.50 (money)
9+5= 14 (amount of coins)
So you would have 5 nickeled and 9 quarters.
Answer: She would need 32
Step-by-step explanation:
ANSWER: M(-9,-4) to M’(-5,2)
If (x,y) is to (x+4,y+6)
Then (-9,-4) is to (-9+4,-4+6)
Hence (-9,-4) is to M’(-5,2)
Hopefully it’s correct
