What is the solution to the system of linear equations? 2x + y = 7
x - 2y = 16
(4.-1)
(-1.9)
16.-5)
(-5.6)

(6,-5)

Step-by-step explanation:

I used a graphing tool to graph the system. When graphed, the lines cross at point (6, -5). Therefore, the solution to the system of linear equations is (6,-5).

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
