Complete question is;
Henri conducts an experiment to determine who likes peanut butter more: boys or girls. He has 25 girls and 25 boys taste some peanut butter and then rate it on a scale of 1 - 10 with 1 being cannot stand and 10 being tastes delicious. He finds that the girls had a mean of 7 with a range of 9 and the boys had a mean of 8 with a range of 5. Which statement is true?
A) On average, girls like peanut butter more than boys.
B) The person who rated peanut butter the worst was a boy.
Reactivate
C) Girls varied more in how they liked peanut butter than the boys did.
D) There is not enough information to know if any of the above are true
Answer:
Option C) Girls varied more in how they liked peanut butter than the boys did.
Step-by-step explanation:
From the options the most appropriate will be option C which says: Girls varied more in how they liked peanut butter than the boys did..
This is because in the experiment, henri found out that the girls had a mean of 7 with a range of 9 and the boys had a mean of 8 with a range of 5.
The range of the girls responses are far higher than that of the boys.
So it means their ratings were more varied and not within similar ratings scale.
Wouldn't you use sin, cos, tan?

Step-by-step explanation:
You have the right idea that things need to get multiplied.
What should be done is that the entire fraction needs to get multipled by the lowest common denominator of both denominators.
Let's look at the complex numerator. Its denominators are 5 and x + 6. Nothing is common with these, so both pieces are needed.
The complex denominator has x - 3 as its denominator. With nothing in common between it and the complex numerator, that piece is needed.
So we multiply the entire complex fraction by (5)(x + 6)(x -3).
Numerator: 
= (x+6)(x-3) - (5)(5)(x-3)
= (x+6)(x-3) - 25(x-3)
= (x-3)(x + 6 - 25) <--- by group factoring the common x - 3
= (x -3)(x - 19)
Denominator:
Now we put the pieces together.
Our fraction simplies to (x - 3) (x - 19) / 125 (x + 6)
