Answer: 
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where 
is the sample proportion, n is the sample size , 
is the critical z-value.
Given : Significance level : 
Sample size : n= 85
Critical value : 
Sample proportion: 
Now, the 99% confidence level will be :
Hence, the 99% confidence interval estimate of the true proportion of families who own at least one DVD player is
13x=8x+25
5x=25
X=5
5 is the answer

</span>
Answer: 118% of 19 is 22.42
The answer is A.
1/2*12*25
6*25
150 square inches
Divide 6 2/3 by 4 and you get an x value of 1.67 to double check the answer we can multiply 1 2/3 by 4 and we get 6 2/3
