Answer:
C) 12/20
Step-by-step explanation:
Between 1 and 20, 10 numbers are even, 4 numbers are perfect squares (1, 4, 9, and 16), and 2 numbers are both even and perfect squares (4 and 16).
So the probability is:
(10 + 4 − 2) / 20 = 12/20.

Answer:
28%
Step-by-step explanation:
We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.
First, subtract the two numbers
94 - 68 = 26
Put 26 over 94 to make this 26/94
Divide to get 0.28 (simplified and rounded)
So the increase was 28%
* The answer is in the explanation below*
Simple interest is calculated only on the initial amount (principal) that you invested.
Example: Suppose you give $100 to a bank which pays you 5% simple interest at the end of every year. After one year you will have $105, and after two years you will have $110. This means that you will not earn an interest on your interest. Your interest payments will be $5 per year no matter how many years the initial sum of money stays in a bank account.

How much will an investment of $500 be worth in the future?
Initial investment: $500
Yearly deposits: $0
Interest rate: 6.00%
Years Invested: 20
At the end of 20 years, your savings will have grown to $1,604.
You will have earned in $1,104 in interest.
