To start we need to add all the pizzas to see how many total they made.

21+14+14+23=72

then the probablility that it is not a cheese pizza is the same as the probability that it is one of the other types

14+14+23=51

there is a 51/72 chance that the next pizza is not a cheeze pizza which equals 0.71 equaling a 71% chance

I hope I've helped!

The probability of the next pizza not being cheese is
P(not cheese) = 100 - P(cheese)

the probability of it being cheese is 21/(total)
Total = 21 + 14 + 23 + 14
Total = 72

So, P(cheese) = 21/72 x 100
which is roughly 29%

So P(not cheese) = 100 - 29 = 71%

3x+4y+z=-2<br> 2y+3z=-8<br> z=-3
masya89 [10]

Answer:

z=-3 so 2y+3(-3)=-8, 2y-9=-8, add 9 to both sides 2y=1 divide both sides by 2, y=1/2, so 3x+4(1/2)+-3=-2, 3x+2-3=-2, 3x-1=-2, add 1 to both sides, 3x=-1, divide both sides by 3, x=-1/3
