It's just an estimate. There's no telling how close it is.
To estimate using just the information in the table,
ASSUME that the average of all the students in each
slot is the average time of that slot.
I know that's confusing. I can't think of a better way to say it,
so here are two examples of what I mean. Look at the table:
-- 6 students said that they spent between 0 and 30 minutes.
ASSUME that those 6 students averaged 15 minutes each.
-- 21 students said that they spent between 60 and 90 minutes.
ASSUME that those 21 students averaged 75 minutes each.
So, when you add up the times for all 50 students, you'll have
(6 x 15 min) + (14 x 45 min) + (21 x 75min) + (9 x 105 min) =
When you total up all those times, divide it by 50 to estimate
the average per student.
Remember ... it's only an estimate.
If the first group had 1 student that spent 2 minutes, and
the other 5 of them spent 29 minutes, then it won't work.
But you'll never know.
Answer:
You need to sum at least 5000 terms
Step-by-step explanation:
Remember what the estimation theorem for alternating series says.
Given a series

An upper bound for the error of the series
is
so

For this case you want

is approximately 5000. So you must sum at least 5000 terms.
Answer:
I think that answer would be 6.
Step-by-step explanation:
If you think about what they are telling you, you will see that XY is a straight line. If the coordinates of y are given and the x is 0, then the midpoint is 3 units away. Midpoint makes the length divided equal so i would add three to the midpoint's x value to get 6. Comment if you have trouble following:)
