Six books at 8 dollars each is equivalent to $48.00
You are only paying 80% of that cost (100%-20%)
Therefore you are multiplying 48 by .8
Your answer should be equal to $38.40
I think it is m= 5/2 and 1/5
The answer would be 64/9. I did this by squaring each number so 8^2 and 3^2 should give me 8*8 which is 64 and 3*3 which is 9. I hope this helped you!
Answer: 14
Step-by-step explanation:
- Degrees of freedom is the number of values in the evaluation of a test statistic that are free to vary.
For t-statistic , the degree of freedom for a sample with sample size 'n' is given by :-

Given : Sample size : n-1
Then, the number of degrees of freedom the t-value will have :-

Hence, the t-value will have 14 degrees of freedom.
