Solve each system by elimination
-4x+y=-10
6x-y=16

The y variable in both equations are opposites. So, we can add the two systems together to eliminate y and solve for x.

-4x + y = -10

6x - y = 16

2x = 6

2 × 3 = 6.

x = 3. Now we have to solve for y. Let's use 6x - y = 16.

6(3) - y = 16

18 - y = 16

18 - 2 = 16, so y = 2.

x = 3

y = 2.

Or if you have to put it in coordinate form: (3, 2)

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
