Here is the solutions for 3-11
Answer:
D
Step-by-step explanation:
I got it right on Khan Academy
So let's leave the 112 aside for now. The question then becomes how to write the decimal 0.001 as a fraction. The key is to remember that
0.x corresponds to "tenths" so x/10
0.0x corresponds to "hundredths" --> x/100
0.00x corresponds to "thousandths" --> x/1000
The number 0.001 is just 1 thousandth, or 1/1000
Now back to 112.001. You can write it as
112/1 + 1/1000 =
(112,000+1)/1000 =
112,001/1000 (the fraction you were looking for)
Let me know if you have questions
Answer:
d. 2 in the numerator, 15 in the denominator
Step-by-step explanation:
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
If we assume that we have
groups and on each group from
we have
individuals on each group we can define the following formulas of variation:
We want to test this hypothesis:

And we have this property
The degrees of freedom for the numerator on this case is given by
where k =3 represent the number of groups.
The degrees of freedom for the denominator on this case is given by
.
And the total degrees of freedom would be
On this case the correct answer would be 2 for the numerator and 15 for the denominator.
d. 2 in the numerator, 15 in the denominator
You didnt show the rest of the picture i can't help if i can't see.
