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.

Can someone teach me how to balance algebra equations, I just don't get how to do it. Like with fractions?
natka813 [3]

Answer:

<h3>Move all the x terms to one side. Use inverse operations and add 1 5 x 15x 15x to both sides to keep the equation balanced. Solve by working backwards from the order of operations. This means we need to undo the −2 first by adding 2 to both sides of the equation to keep it balanced.</h3>

On the second day of a hiking trip, the tourists covered 17% bigger distance than on the first day. By how many percent did thei
finlep [7]
Speed=distance/time
suppose the distance of the first day is d, and the time is t
distance of the second day: d+0.17d=1.17d
time of the second day: t+0.2t=1.2t
speed of the second day: 1.17d/1.2t=0.975(d/t)=(1-0.025)(d/t)
so the speed of the second day is 2.5% slower than the first day.
