The degrees of freedom for the numerator of the F ratio can be calculated to be 9.

<h3>How many degrees of freedom is the numerator of the F ratio?</h3>

The degrees of freedom for the numerator can be found to be:

= number of exams graded - 1

Solving gives:

= 10 - 1

= 9

In conclusion, the degrees of freedom for the numerator of the F ratio is 9.

Please help with the following question
Alex17521 [72]
P1=(0,0)=(x1,y1)→x1=0, y1=0
P2=(3,-2)=(x2,y2)→x2=3, y2=-2

Slope: m=(y2-y1)/(x2-x1)
m=(-2-0)/(3-0)
m=(-2)/3
m=-2/3

Point-slope equation:
y-y1=m(x-x1)
y-0=(-2/3)(x-0)
y=-(2/3)x

Answer: The equation of the line is: y=-(2/3)x

Three pies were made for a party. Each pie was cut into eight pieces. 3⁄8 of the apple pie was left. 1⁄2 of the cherry pie was l
miskamm [114]

Answer:

There are 13 pieces of pie left.

Step-by-step explanation:

So there are 3 pieces of apple pie left, there are 4 pieces of cherry pie left, and there are 6 pieces of pumpkin pie left. 3 + 4 + 6 = 13.

3/8 = 3 pieces because each fraction in this one equals one piece. So the numerator is how many left.

1/2= 4 because you just divide 8 by 2.

3/4 = 2 because you can multiply the fraction by 2 and get 6/8. Then the numerator is how many that's left.

I hope I helped.
