Answer:
The annual increase in the percentage of a pollution can be determined by some mathematical calculation.
Step-by-step explanation:
- In order to determine the annual percentage increase over one year for a city population, we must do the following,
- First we must subtract starting value that is the initial population of the city at the starting of the year from the final value that is the final population of the city at the end of the year.
- Now divide the whole by the starting value.
- This gives you the value of increase in the rate of growth, Now inorder to obtain it in percentage format, we must multiply the resultant value by 100.
This finally gives you the rate of increase in the population in percentage.
The equation in H form is :-
h = πr2/v
Scores on an AP Exam at a local high school are recorded in the table. What was the average score?
Answer: D) 4.266 is correct
Explanation:
We are given the below frequency table:
Score Frequency

4 | 16
5 | 22
Let's denote the score by 
and frequency by 
.
The average formula is:

❖ 8² - (4+2)² × 2 ÷ 4 = 46
Follow order of operations:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
(Note: Multiplication and division can be done in either order as well as addition and subtraction.)
First, do parenthesis and exponents:
(4 + 2)² = 36 8² = 64
Now do multiplication and division:
36 x 2 ÷ 4 = 18
Now do subtraction:
64 - 18 = 46
