Answer:
what is that ............
Step-by-step explanation:
there is no big "trick" involved.
you just need to do the multiplication and then move the terms into the right spot, so that the x-, y- and constant terms are in the same place as the generic Ax + By = C
y + 5 = 4(x + 1)
y + 5 = 4x + 4
-4x + y = -1
or (after multiplying both sides by -1)
4x - y = 1
yes, B = 1 (or -1), so you could write 1y (or -1y) instead of only y (or -y).
but nobody does that.
Answer:
0.0001
Step-by-step explanation:
The computation of the probability of experiencing such a drop in water pressure is shown below:
Given that
mean = 519,645 gallons
Standard deviation = 71,564 gallons
Now the probability is
= 1 - p (x - mean ÷ standard deviation < 782,238 - 519,645 ÷ 71,564)
= 1 - p(z<3.67)
= 1 - 0.9999
= 0.0001
