1) For the data in the table, does y vary directly with x? If it does, write an equation for the direct variation. x y
10 15
16 24
20 30

a) yes; y=1.5x
b) yes; y=2x
c) yes; y=x+5
d) y does not vary directly with x

2) Same as above.

x y
16 4
32 16
48 36

a) yes; y=2x
b) yes; y=4x
c) yes; y=8x
d) no; y does not vary directly with x

Thank you!

the answe i =−n+5

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
