Answer:
23
Step-by-step explanation:
To calculate mean, add numbers and divide by amount of numbers
30 + 28 + 8 + 26 = 92
92/4 = 23
A rational number is: A number that can be written as a quotient of 2 integers, where the divisor is not 0.
Example: 2/5 , -6,
Because you can write any integer as a quotient with a denominator of 1, all integers are rational numbers,
Example: 5 = 5/1

He will pay the 10% of $7200, and that is calculated like so:
(10%)(7200)
= (10/100)(7200)
= (1/10)(7200)
= 720
therefore he will pay $720
Number 5a. is 26.78 and 5b. is 8.5
Well if I am reading this right the question is 9000 divided by 1/2 which would basically equal to 9000 times 2. The answer is 18000.
