Five students make the following guesses on the number of jelly beans in a jar:72,78,68,60,84.The guesses were off by 14,2,4,6 an 10 (not in order). How many jelly beans are in the jar.

my answer is 74.

You are right.

thank you

how did you get 74?

To find the number of jelly beans in the jar, we need to analyze the information given. We are told that five students made guesses, and their guesses were off by 14, 2, 4, 6, and 10.

To start, let's list the guesses in increasing order: 60, 68, 72, 78, 84. Since these are the guesses, we can assume they are close to the actual number of jelly beans in the jar.

Next, let's list the deviations (how much the guesses were off by) in increasing order: 2, 4, 6, 10, 14.

The deviations are not in order, so we need to rearrange them according to the order of the guesses. We have:
60 (2)
68 (4)
72 (6)
78 (10)
84 (14)

Now, let's find the average deviation. The average deviation is calculated by summing up all the deviations and dividing by the number of deviations. In this case, we have 2 + 4 + 6 + 10 + 14 which equals 36. Dividing this by 5 (the number of students) gives us an average deviation of 7.2.

Next, to find the actual number of jelly beans in the jar, we need to determine which of the guesses is closest to the average deviation. Looking at the deviations, we see that the guess of 72 is the closest to the average deviation of 7.2.

Therefore, the estimated number of jelly beans in the jar is 72. So, your answer of 74 is close, but not accurate according to the given information.
