Answer: I got 376.8 cm^3
Step-by-step explanation:
Plug in 6 for r and 10 for h in the following formula:
1/3 of 1/4 is the same as 2/6 of 2/8
(easier for me this way)
2/6 is 0.33
2/8 is 0.25 so you are in essence finding roughly 0.8333
that would be equal to the diagram at the bottom right
The other question is (i believe) 1/5 of 5/6
1/5 is 0.2, 5/6 is 0.833
another way to do it is to divide 833 by 5 is 166.6 so it would be 0.166
that would (i think) be the top right
Answer:
c.Observational study. The variable of interest is the result of either correct or incorrect to each trial.
Step-by-step explanation:

A nine year old tested professional observes therapists choices and the choice of therapist can be correct or incorrect. So, the variable of interest is the result of either correct or incorrect to each trial.
5 - substitute the numbers 1-10 for n in (3n-4) and add up all your answers. So (3(1)-4) + (3(2)-4)...
