Of students in the AP curriculum at a prep school, 40% take one AP exam, 45% take two AP exams, and the remaining 15% take 3 AP
aliya0001 [1]

It should be noted that the probability that a student will earn at least one 5 will be 0.3152.

<h3>How to calculate the probability</h3>

Test P(x). P(at least one 5)

1. 0.4. 0.2

2. 0.45. 0.36

3. 0.15. 0.488

Therefore, the probability that a student in the AP curriculum will earn at least one 5 will be:

= (0.4 × 0.2) + (0.45 × 0.36) + (0.15 × 0.488)

= 0.3152

In conclusion, the correct option is 0.3152.

Lisa's store collects 5% sales tax on every item sold if if she caused if she collected $22. In sales tax what was the cost of t
Advocard [28]
Im assuming the question is asking: if she collected $22 in sales tax what was the cost of the items her store sold.  you should make sure you type the question correctly otherwise it'll be hard to answer.

going with my assumption of what the question is, we want to find the total cost of all items her story sold.  let that cost be c. since there is 5% sales tax on everything and we know the sales tax is worth $22,m we have:

5%(c) = 22
dividing both sides by 5% (or .05) gives:
c = $440
