Answer:
The number of hours did Sarah practice more than Leilani is 
hours .
Step-by-step explanation:
Given as :
The time for which Leilani practiced piano = 
hours
The time for which Sarah practiced piano = 
hours
Let the number of hours did Sarah practice more than Leilani = T hours
<u>Now, According to question</u>
The number of hours did Sarah practice more than Leilani = hours - hours
Or, T = 
hours
Or, T = hours
So,The number of hours did Sarah practice more than Leilani = T = hours
Hence, The number of hours did Sarah practice more than Leilani is hours . Answer
Answer:
5. 1:3
6. Joe
8. 2/3 = 8/12
9. 56/7 = 8/1
Answer:
Joseph is correct
Step-by-step explanation:
I cannot see the options in the drop-down menus. Even though, Joseph is correct because the difference between the longest length (which is 12 ft) and shortest length (which is 9 1/2 ft) is 12 - 9 1/2 = 2 1/2 ft. It doesn't matter how many ropes measure those lengths.

The confidence interval for population mean is given by :-
Given : Sample size : n= 5, since n<30 , so the test we use here is t-test.
Sample mean : 
Standard deviation: 
Significance level : 
By using the standard normal distribution table , the critical value corresponds to the given significance level will be :-
Now, the 99% confidence interval for the mean waste recycled per person per day for the population of Texas will be :-
Hence, the 99% confidence interval for the mean waste recycled per person per day for the population of Texas = (0.068, 3.732)
