B) y = 5x + 15 and y = -5x + 15 I think.
Answer:
-1
Step-by-step explanation:
It would be 2 if you are talking about the receptacle
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:
![z=\frac{x^{\prime}-u}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx%5E%7B%5Cprime%7D-u%7D%7B%5Csigma%7D)
Thus, we have:
![\begin{gathered} P(x>-1.26)=\frac{-1.26-0}{1} \\ \\ P(x>-1.26)=\frac{-1.26}{1}=-1.26 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20P%28x%3E-1.26%29%3D%5Cfrac%7B-1.26-0%7D%7B1%7D%20%5C%5C%20%20%5C%5C%20P%28x%3E-1.26%29%3D%5Cfrac%7B-1.26%7D%7B1%7D%3D-1.26%20%5Cend%7Bgathered%7D)
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
