Answer:
y=-x
Step-by-step explanation:
It's going left one by one, meaning the slope is negative and has a slope of -1 or -x.
Given:
mean, u = 0
standard deviation σ = 1
Let's determine the following:
(a) Probability of an outcome that is more than -1.26.
Here, we are to find: P(x > -1.26).
Apply the formula:

Thus, we have:

Using the standard normal table, we have:
NORMSDIST(-1.26) = 0.1038
Therefore, the probability of an outcome that is more than -1.26 is 0.1038
(b) Probability of an outcome that
D.
Slope is rise over run and in this case it is -15/ 5 so when it is reduced you get -3 as your slope
A is the right option! Because 0.40 should be in second equation with the x to represent the number of stamps multiply by 40 cents.
