Step-by-step explanation:
<span>–9x(5 – 2x)
= -45x + 18x^2
= 18x^2 - 45x
answer
</span>18x^2 - 45x

Answer:
Option a) 50% of output expected to be less than or equal to the mean.
Step-by-step explanation:
We are given the following in the question:
The output of a process is stable and normally distributed.
Mean = 23.5
We have to find the percentage of output expected to be less than or equal to the mean.
Mean of a normal distribution.
- The mean of normal distribution divides the data into exactly two equal parts.
- 50% of data lies to the right of the mean.
- 50% of data lies to the right of the mean
Thus, by property of normal distribution 50% of output expected to be less than or equal to the mean.
Step-by-step explanation:
V²= U² + 2as
V² - U²= 2as
Divide both sides of the equation by 2s
a= V² - U²/2s (a= square of V minus square of U all over 2s)
