Answer: 69
Step-by-step explanation:
Answer:
Proved
Step-by-step explanation:
Let a, b be two odd numbers
We know odd numbers give remainder as 1 when divided by 2
Hence a and b can be written as
, for some integers m and n.
Now product
=
We have when m and n are integers, 2mn+m+n also will be an integer say s
Then product
again gives remainder 1 when divided by 2
Hence product is odd.

B and E are the correct choices
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.
