Answer:
1120 combinations of four teachers include exactly one of either Mrs. Vera or Mr. Jan.
Step-by-step explanation:
The order in which the teachers are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
1 from a set of 2(Either Mrs. Vera or Mr. Jan).
3 from a set of 18 - 2 = 16. So
![C_{2,1}C_{16,3} = \frac{2!}{1!1!} \times \frac{16!}{3!13!} = 1120](https://tex.z-dn.net/?f=C_%7B2%2C1%7DC_%7B16%2C3%7D%20%3D%20%5Cfrac%7B2%21%7D%7B1%211%21%7D%20%5Ctimes%20%5Cfrac%7B16%21%7D%7B3%2113%21%7D%20%3D%201120)
1120 combinations of four teachers include exactly one of either Mrs. Vera or Mr. Jan.
Answer:
5.24*10³= 5.24*1000= 5240 as decimal shifts towards right

Answer:
1/4th of total cost = $12
so

the game cost is $48
I believe you would take (114*34*2)+(114*1*2)+(1*34*2) equals 8048 squared feet of wrapping paper. I could be wrong. I found the areas of each side and added them together to get a total
Answer:
f(1) is 1, just look at the x-value provided in the parenthesis. f(1) means function value at x = 1, and the graph shows that at x = 1, y = 1.
