The domain is the input number values you can substitute into the equation.

The range is the output values how do they appear like, what is the nature of the numbers.

So for f(x) = 3x - 6/x + 4.5

You can input any real number value for x, except 0, because you can not divide by 0, that is the 6/0.

So the domain is x set of all real numbers except 0. R - {0}

So when we substitute any number into f(x) = 3x - 6/x + 4.5, what kind of numbers do we get?

We get Real numbers, 0 is included.

So the range for f(x) set of all real numbers.

Using the <u>normal distribution and the central limit theorem</u>, it is found that there is an approximately 0% probability that the total number of candies Kelly will receive this year is smaller than last year.

Normal Probability Distribution

In a normal distribution with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure is from the mean.
After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
By the Central Limit Theorem, for n instances of a normal variable, the mean is $n\mu$ while the standard deviation is $s = \sigma\sqrt{n}$ .

In this problem:

Mean of 4 candies, hence $\mu = 4$ .
Standard deviation of 1.5 candies, hence $\sigma = 1.5$ .
She visited 35 houses, hence $n = 35, \mu = 35(4) = 140, s = 1.5\sqrt{4} = 3$
