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.

Answer: a = f/p</h3>
===============================================
Explanation:
We'll solve for 'a' doing these two steps in this exact order
- Multiply both sides by 'a'
- Divide both sides by p
We do this because we're following PEMDAS in reverse to isolate the variable we want.
The steps look like this
p = f/a
pa = f
a = f/p
Note how ultimately the 'a' and p variables swap places when going from p = f/a to a = f/p
Answer:
12x+20
Step-by-step explanation:
Perimeter of a garden = 4s, s being the length of the side
In this case, s = 3x+5
substitute the equation
4(3x+5)
=12x+20
