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:
15cm
Step-by-step explanation:
circumfrince of a circle = pi
Answer:
1 unit right and 3 units up
Step-by-step explanation:
The graph of the given function has equation
This is obtained after translating the graph of
We can rewrite f in terms g to obtain:
This is a shift to the right by 1 unit and and a shift up by 3 units.
Therefore
is a translation of
1 unit right and 3 units up
7w + 3 = 5w + 9
Step 1:
Get the 3 to the other side by subtracting
7w = 5w + 6
Step 2:
Get the 5w to the other side by subtracting
2w = 6
Step 3
Divide
6/2 = 3
Answer is 3
