Probability of selecting a male

First, we need to get the total population;

Let P(Male) represent Probability of Male

Let n(Male) represent number of Male

Simplify fraction by dividing the numerator and denominator by 4

Hence, the probability of selecting a male is 1/3

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

x       y

0       8

1       7.6

2       7.2

3       6.8
