How do you graph (x+2) (x-4)
2 answers:
Hey!
I find the easiest way to do this, is by changing it into slop-intercept form: y = mx+b (or simply foil the problem, and plug it into your graphing calculator)...
(x+2)*(x-4) > I'm assuming that this is what that equation looks like....
x^2 + 2x - 4x - 8
x^2 - 2x - 8

What I did at the bottom (the graph uploaded) is a graph I made for you, to help you out! Cause I know it gets confusing in math...

How graphing works is m is the slope, b is the point (in this case the bottom point), and the x^2 tell you that is a parabola (or whatever the term is)...

Answer:
Therefore, the probability is P=0.000064.
Step-by-step explanation:
We know that a pressure control apparatus contains 3 electronic tubes. The apparatus will not work unless all tubes are operative. If the probability of failure of each tube during some interval of time is 0.04.
We calculate the probability of failure of the apparatus.
We get:
Therefore, the probability is P=0.000064.
