Ruby flipped the coin and spun the spinner below. What is the probability that the coin will land on heads AND the spinner will land on either a 2 or a 3?
A. 1/2
B 1/4
C. 1/10
D. 1/3

B.  1/4.

Step-by-step explanation:

There are 2 2's and 3 3's on the spinner and a total of 10 sectors, so the probability of getting a 2 or 3 = 5/10 = 1/2.

The probability of a head is 1/2.

So the required probability = 1/2 * 1/2 = 1/4.

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
