Why is the percent not the same as the percent you find from he percent of money

Percentage is a way to express a relation between two numbers as a fraction of 100<span>. In other words, the percentage tells us how one number relates to another. If we know that number A is </span>25%<span> of number </span>B<span>, we know that </span>A<span> to </span>B<span> is like </span>25<span> is to </span>100<span> (one more transformation: </span>A<span> is four times smaller than </span>B<span>). This is Percentage Calculator's lesson on what is percentage.
But in money a percent is how many cents past the dollar the number is.</span>

Last year, a person wrote 126 checks. Let the random variable x represent the number of checks he wrote in one day, and assume

Arisa [49]

Answer: The mean number of checks written per day $=0.3452$

Standard deviation $=0.5875$

Variance $=0.3452$

Step-by-step explanation:

Given : The total number of checks wrote by person in a year = 126

Assume that the year is not a leap year.

Then 1 year = 365 days

Let the random variable x represent the number of checks he wrote in one day.

Then , the mean number of checks wrote by person each days id=s given by :-

$\lambda=\dfrac{126}{365}\approx0.3452$

Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e. $\sigma^2=\lambda=0.3452$

Standard deviation : $\sigma=\sqrt{0.3452}=0.5875372328\approx0.5875$

Answer:

$946$

Step-by-step explanation:

we know that

The formula to find the sum is equal to

$S=(a1+an)n/2$

where

a1 is the first term

an is the last term

n is the number of terms

In this problem we have

$n=11$

$a1=(98-2(1))=96$

$an=(98-2(11))=76$

substitute the values in the formula

$S=(96+76)(11/2)=946$
