Katena32 [7]

Answer:

33.3%

Step-by-step explanation:

Defining:

A: a student plays football

B: a student plays baseball

Data:

P(A∩B): a student plays football and baseball = 0.06

P(A) = 0.18

The probability that a student plays baseball given that he plays football is calculated as follows:

P(B/A) = P(A∩B)/P(A) = 0.06/0.18 = 0.33

Answer:

y= 10x + 4

Step-by-step explanation:

-10x + y = 4

-10x + y +10x = 10x + 4

y= 10x + 4

depending on what its asking usually this is what its asking for but im not sure exaclty what its asking so here.....

next step is to plug the numbers in

so for the first box it says that x is -2

plug it in.....

y = 10(-2) + 4

y = -20 + 4

y = -16

then keep doing it for the next boxes.....

second box:

y = 10(-1) + 4

y = -10 + 4

y = -6

third box:

y = 10(0) + 4

y= 4 because 10 times zero is zero (basically any number times 0 is zero)

fourth box:

y = 10(1) + 4

y = 10 + 4

y = 14

fifth box:

y = 10(2) + 4

y = 20 + 4

y = 24

Hope this helps!
