Shiloh wants to earn
at least $200. That means the number of cakes, x, that she sells has to earn her at least $200. For the inequality, the want number the least number of cakes possible to earn her $200 on the left side of ≤ and the most cakes possible she can sell on the right side of <span>≤.
Calculate the least amount of cakes she can sell to make $200. To do this, divide $200 by $5, since each cake is selling for $5.
</span>
<span>
That means she has to sell at least 40 cakes to meet her goal. That number, 40, goes to the left of </span>≤. Since she has 100 cakes to sell, 100 goes to the right of ≤. x can fall between 40 and 100, including both numbers, making your inequality 40 ≤ x ≤ 100.

The answer is B) 4</span>
0 ≤ x ≤ 100.<span>

Answer:
The intersection region shown in the graph attached is the solution of the system of inequalities
Answer:
P = 0.0909
Step-by-step explanation:
To know the number of ways or combinations in which we can select x elements from a group of n elements, we can use the following equation:
So, if you sat down at your computer and randomly loaded 4 of the 12 problems, there are 495 different possibilities and it is calculated as:
Then, from 495 different possibilities, there are 45 possibilities that both this problem and Richard Rusczyk's problem were among the four you loaded. This 45 possibilities are calculated as:
Because you need to select: this problem and there is only one, the problem that Richard Rusczyk wrote and there is only one, and 2 problems from the other 10.
Finally, the probability that both this problem and Richard Rusczyk's problem were among the four you loaded is equal to:
For a * = 2bc
for b * = 5ab
