Answer:The mean number of checks written per day = 0.3370
The standard deviation = 0.5805
The variance = 0.3370
Step-by-step explanation:
Let the random variable x represent the number of checks he wrote in one day.
Given : The number of checks written in last year = 123
Let the number of days in the year must be 365.
Now, the mean number of checks written per day will be :-

We know that in Poisson distribution , the variance is equals to the mean value .


Thus, Standard deviation = 0.5805
So we know 5ft to 1cm then
4x5=20ft
6x5=30ft
The answer is 2, yous add all of them up and divide by how many there are.
For the answer to the question above asking to f<span>ind the coordinates of Z without using any new variables.

Vector WZ equals vector VP, which is (p, -q)
So Z is (-p - r + p, q - q) which is (-r, 0)
I hope my answer helped you.
First, you need to analize and understand the problem, then you must choose and strategy. There is a wide variety of strategies to solve a mathematical problem, in this case, you can use the following, which is based on the information given above:
1. You have that t<span>he sum of three consecutive even integers is </span>

<span>, therefore, you can given the variable </span>

<span> to the first integer, the second even integer is </span>

<span> and the third one is </span>

<span>.
2. Calculate x:
