Number one two and four are true
1. 3+5=8 and 8 is 80% of ten
2.the prob of drawing a red marble in the first go is 3/10 x 5/9 (for the probabilty of drawing a green one in the second go) =1/6
3. The probability OF drawing a blue marble is 20% (hence false)
4. 3+2 = 5, the same amount of red and blue marbles together as of green ones
Using proportions, it is found that:
a) A raise of $500 would be equivalent to a percentage of 80%.
b) From the above percentage, it would fall into the Gold Award range.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using arithmetic operations such as multiplication and division.
One example of application of proportions is for percentage problems, as a percentage is given by the amount a divided by the total amount b, and multiplied by 100%.
The goal of the raise is of $625, hence b = 625, and considering a raise of $500, a = 500, hence the percentage of the raise is given as follows:
500/625 x 100% = 80%.
To find the range of the raise, we look at the table. For a percentage of 80%, the amount is a Gold Award contribution.

Step-by-step explanation:
Answer:
x = 7.8
Step-by-step explanation:
2.6 + x = 10.4
-2.6 -2.6
x = 7.8
