Question

Mr. Brown made 5 trips to the sushi bar. On his first trip, he got 14 pieces of sushi. On his second trip, he got 12 pieces of sushi. On his third trip, he got 22 pieces of sushi. On his fourth trip he got 8 pieces of sushi. On his final trip, he got 24 pieces of sushi. What was the average (use the mean) number of pieces of sushi he got on each trip to the sushi bar?

Answer 1

Answer: 16 pieces.

Explanation:

Suppose that we have a set with N numbers

{x₁, x₂, x₃, ..., xₙ}

The mean of this set is calculated as:

M = (x₁ + x₂ + x₃ + ... + xₙ)/N

In this case, our set is:

{14, 12, 22, 8, 24}

So we have N = 5.

The mean of this set will be:

M = (14 + 12 + 22 + 8 + 24)/5 = 16

The average/mean number of pieces of sushi he got on each trip is 16 pieces.
