Do Now: Mona tried to
solve the
system by
graphing:
x + y = 6
2x - y = 6
What was
Mona's
mistake?
Based on her
graph (shown)
Mona thinks
the solution is
(0,6).

Mona's Mistake: Well, Mona tried to graph something not yet solved.

She should have solved the problems.

x+y=6 Solved is  y=-x+6

              and

2x-y=6 Solved is  y=2x-6

I have also graphed these two points for you, and they intersect at (4,2)

Have a beautiful day, and stay safe.

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
