Two red cubes, two green
cylinders, and three yellow
rectangular prisms were placed
into a bag. If you reach into the
bag and pull out an object, what
is the probability that it will not
be a red block?
:

7/5

Step-by-step explanation:

All items add up to 7, subtract 2 because there are 2 red cubes and put it under a 7 in fraction form and you'll get the probability

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

x=30
