Answer:
Check below for the answer and explanation.
Step-by-step explanation:
Studying the central tendency alone is not sufficient because apart from calculating the value of the central point of a group of data ( which is what the measure of central tendency does), it is important to also understand the spread of these data about the average(mean) value.The measure of dispersion will help us to know the range of error that is recorded in both descriptive and inferential statistics and this will enable the statistician to assess the validity of the data generated from the experiment performed.
A small value of standard deviation indicates that each of the values in the dataset is close to the average (mean) value.
Ok so we know that she pays a 10% tax for her first $8925, so she will pay $892.50
She will pay an extra 15% of income from $8925 to $36250, so she will pay 15% of 27325 (36250-8925), which is $4098.75
Then she pays 25% of income from $36250 to $87850, but she only earns $65000, so she will pay 25% of $(65000-36250), or 25% of 28750 which is $7187.50.
So in total she will pay $892.50 + $4098.75 + $7187.50
And that amount is $12178.75
So Ms. Lee needs to pay $12178.75 in tax
Hope this helped
Based on the calculations, the rate of change for the function is equal to 5.
<h3>How to calculate the rate of change?</h3>
Mathematically, the rate of change for the function can be calculated by using this expression;
Rate of change = [½ ÷ ⅒]/[0 - (-1)]
Rate of change = 5/1
Rate of change = 5.
Rate of change = [5/2 ÷ ½]/[1 - 0]
Rate of change = 5/1
Rate of change = 5.
Rate of change = [125/2 ÷ 25/2]/[3 - 2]
Rate of change = 5/1
Rate of change = 5.

It would be 4(x) +7 so i would go with the third one
