This is conditional probability  because you are not replacing the marble. That means on the second pick you'll have one less marble and you want to multiply your fractions together not add them,so..

Aaron wants a raise in his salary to $12.00 an hour. His hourly pay right now is $9 an hour. He decides to ask his boss for a 25
Dafna11 [192]
I do not agree . 25% of his hourly pay equals $ 2.25
.25 * 9 = 2.25
9+2.25=11.25
He wants his hourly pay to be $12 .
12-9 = $3
so, he needs his hourly pay to be increased by $3 to reach his goal.
$3 is 1/3 of his current hourly pay .
1/3 = 33%
now .33*9= $ 3
* means times ( multiplied by)
Hope that this helps !

A farmer is comparing the number of eggs laid by two hens. The first hen laid 8 eggs per week for x weeks. The second hen laid 9
CaHeK987 [17]

Answer:

8x > 9y

Step-by-step explanation:

Since the first hen laid 8 eggs a week, the amount of eggs can be represented by 8x.

The second hen laid 9 eggs a week, so it can be represented by 9y.

The first hen laid more eggs than the second hen, so use a greater than inequality.

Put this all together:

8x > 9y represents this relationship
