A man chooses a card at random from a pack of playing cards. What is the
probability that the card is a diamond?

13/52

Step-by-step explanation:

as there are 13 diamond cards out of the total 52 cards

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

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   c

for every x value there is only one y value

x       y
