If you rolled a number cube 100 times, how many times would you expect to get an even number? a.25 b.75 c.50 d.38

C.50

Step-by-step explanation:

One a dice there are 3 even numbers  (2,4,6) and 3 odd numbers (1,3,5)

P(even) =  even numbers/ totals

             =3/(3+3)

              =3/6

               = 1/2

Out of 100 times, take the number of times rolled multiplied by the probability

100 * 1/2 = 50

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
