Answer:
The answer is 4
Step-by-step explanation:
For a poisson distribution, the variance is equal to the mean. Since the average number of defects per product is 2, it means that the mean per product is 2. Hence for 32 units it is 16 divided by 2 which is 16.
Also, since the square root of variance is equal standard deviation, the square root of 16 is 4.
50 because half the number of people are zombies.
There are an infinite number of them. The smallest one is 42,
and every multiple of 42 is another one.
I don't remember the official correct way to solve this problem.
I can only show you my own way of doing it.
I take the bigger number, and I go through its multiples, one by one,
until I spot one that's also a multiple of the smaller one.
Example: 6 and 7.
Go through the multiples of 7:
7 ... no, not a multiple of 6
14 ... no, not a multiple of 6
21 ... no, not a multiple of 6
28 ... no, not a multiple of 6
35 ... no, not a multiple of 6
<em><u>42</u></em> ... Yes ! A multiple of 6. yay !
Answer:
D
Step-by-step explanation:
