When you have to count in how many ways you can arrange something, you need permutations: you have 9 possible students to schedule as first, the second visit will be scheduled with one of the remaining 8 students, the third one with one of the remaining 7 students, and so on until the last one, therefore:
9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 362880
The students can be scheduled in 362880 ways.
If 3 pounds cost $8.31, then the product is being sold as 1 for $2.77.
If 5 pounds cost $12.59, then the product is being sold as 1 for $2.51.
It is better to buy 5 pounds for $12.59 because you are getting more for your money.
Answer:
Step-by-step explanation:
Shaded region is the difference of the areas of the rectangles
<u>Area of the bigger rectangle:</u>
<u>Area of the smaller rectangle:</u>
- A = (x + 2)(x + 8) = x² + 10x + 16
<u>Area of shaded region:</u>
- A = 4x² + 8x - x² - 10x - 16 = 3x² - 2x - 16
Answer:
When the price of a ticket = $0 or $40, there will be no revenue.
The revenue will be $500 if each ticket cost $37.3 or $2.68
Step-by-step explanation:
Let R(p) = p(200-5p)
when R(p) = 0
p(200-5p) = 0
p = 0 or 200-5p = 0
When the price of a ticket = $0 or $40, there will be no revenue.
when R(p) = 500
200p - 5p² = 500
5p² - 200p + 500 = 0
p = $37.3 or $2.68 (3 sig. fig.)
The required prices are $37.3 and $2.68
