The mean of a set of 5 numbers is 39 and the median is 40. if the mean of the largest two numbers is 49 , then what is the sum of the smallest two?

Sum of 5 numbers = 39*5 = 195

largest two numbers sum = 49*2 = 98

median = 40

sum of smallest two numbers = 195-(98+40) = 195-138 = 57

Sum of 5 numbers = 39*5 = 195

largest two numbers sum = 49*2 = 98

median = 40

sum of smallest two numbers = 195-(98+40) = 195-138 = 57

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

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
