Step-by-step explanation:
you should know that the sum of interior angles of a hexagon is 720 so
Ignore the more complicated fraction. All they care about is finding the LCD of y and (y-3)/3
Think of the first y as y/1. We can write this as 3y/3 (multiply top and bottom by 3)
So y + (y-3)/3 turns into 3y/3 + (y-3)/3. At this point we can combine the fractions since the denominators are both 3.
Final Answer: Choice D) 3

4188.79
Step-by-step explanation:
I used the googIe calculator but a formula you can use is V = 4/3 πr³
Have a nice day.
Step-by-step explanation:
The degree of freedom for t statistic is 11.
According to the given question.
For a repeated-measure study, comparing two treatments with 12 scores in each treatment .
So, we can say that sample size, n = 12.
We know that, when you have a sample and estimate the mean, we have
n – 1 degrees of freedom, where n is the sample size.
Therefore,
The degree of freedom for the given sample test will be
d.f = n -1
⇒ d.f = 12 - 1
⇒ d.f = 11
Hence, the degree of freedom for t statistic is 11.
