The average of the three numbers, 2, 3, and x-1 is n. what is the value of x in terms of n?

the average of a dataset is simply the "arithmetic mean", and is just the sum of the data items divided by how many items are there.

well, in this case we have 3 items, 2, 3 and (x-1), so, to get their average, we sum them up and divide them by 3, but we already know that's n, well

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
