If you are told a population has a mean of 25 and a variance of 0, what must you conclude?

According to the definition of mean and variance, a mean of 25 and a variance of 0 implies that all the elements in that population are equal to 25.

Step-by-step explanation:

Given :

Mean,

Variance,

Solution :

Variance -

Variance measures how far each number in the set is from the mean and thus from every other number in the set.

Mean -

Adding all numbers in the data set and then dividing by the number of values in the set.

According to the definition of mean and variance, a mean of 25 and a variance of 0 implies that all the elements in that population are equal to 25.

lol, i have been using this product for a while and the second half of the year for a lon and the first time in a long time ago that the government has not yet received enough votes to be a good the first place in the world to be able to do it in my world life, i

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
