The first contract can go to any of 12 firms. The second can go to any of the remaining 11 firms, and so on. Finally, the 4th contract can go to any of the 9 firms that don't yet have a contract.
The number of ways the contracts can be awarded is
... 12×11×10×9 = 11,880
The relative frequency for Pooja, Melissa, Ernesto, and Dalia is 0.33, for Salma and Olga is 0.66, and for Pedro and Divya is 0.
<h3>What is the relative frequency?</h3>
The relative frequency describes through a percentage (0% to 100%) or an equivalent, the frequency of an event. Here are some examples:
- If in a city it rains 15 out of the 30 days, the relative frequency is 50% or 0.5.
- If a specific soccer team never wins matches, the relative frequency for winning is 0% or 0.
<h3>How to calculate relative frequency?</h3>
To find relative frequency simply use this formula
- total of occurrence of a specific event/ total possible events or outcomes.
Let's use this formula to calculate the frequency of classes failed by each child.
1/ 3 = 0.33
1/3 = 0.3
2/3 = 0.66
0/ 3 = 0
1/3 =0.33
1/3 = 0.33
2/3 = 0.66
0 /3 = 0
Finally, create the bar graph using the information.

Step-by-step explanation:
Answer:
-9y + 5x + 3
Step-by-step explanation:
-8y - (4x - 3) - y + 9x:
Group like terms = -(4x - 3) -8y - y + 9x
Add similar Elements - 8y - y + 9x = - (4x - 3) - 9y + 9x
Apply the distributive law: - (a - b) = -a + b = - (4x -3) = -4x + 3
= 4x + 3 - 9y + 9x
Group like terms = -9y - 4x + 9x + 3
Add similar Elements -4x + 9x = 5x
= -9y + 5x + 3
