There are 5 red cherries and 10 yellow cherries on a plate. If the average weight of red cherries is 2 oz and the average weight of the yellow cherries is 3 1/2 oz, what is the average weigh of all cherries on the plate?

3 oz.

Step-by-step explanation:

Average weight = total weight / number of cherries

Weight of red cherries =  5*2 = 10 oz.

Weight of yellow ones =  10* 3 1/2 =  35oz.

So the answer is  (10 + 35) / 15 = 45/15

= 3 oz.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value
