Answer: All I know is C is one of them. I’m trying lol
Step-by-step explanation:
The df value for the t statistic for this study is 12.
To calculate the df value or degree of freedom we have to learn about test-statistic.
<h3>What is t statistics and how is it related to df(degree of freedom)?</h3>
In the field of statistics , T-statistic is the ratio of the estimated value of the perimeter to its standard error. Degree of freedom or df value denotes the number of data (from a sample) is used to calculate the estimate .
Importantly the degree of freedom is different from the sample space of an experiment.
The formula for calculating the df of a function is given by
df=N1+N2-2
So in the given question, N1=6 and N2=8
Substituting the values we get df=N1+N2-2=8+6-2=12 .
Therefore the value of the degree of freedom is 12.

Answer:
-20=0
Step-by-step explanation:
Answer:
Step-by-step explanation:
To find the additive inverse of polynomial expression, flip the sign of each term.
6x² ----> -6x²
-x -----> +x
-2 -----> +2
Additive inverse:
-6x² + x + 2
Answer:
y = 68 degrees
Step-by-step explanation:
Here, we want to solve for an equilateral triangle with the internal angle measurement being y-8
If one of the angles is y-8, then the rest are y-8 too
mathematically, by adding all , we have a total of 180
Thus;
3(y-8) = 180
y-8 = 180/3
y-8 = 60
y = 60+8
y = 68 degrees
