Answer:
There are 1,585,080 ways for her to select students and assign them to the jobs
Step-by-step explanation:
The order in which the students are selected is important, since different orderings means different jobs for each student selected. So the permutations formula is used to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
In this problem:
4 students selected from a set of 37. So
There are 1,585,080 ways for her to select students and assign them to the jobs

For the first question the answer would be Enlarged.
For the second question, the Scale Factor is 1/4, which is a reduction
Answer:
set middle number=x
then left side number=x-1
and right side number=x+1
(x-1)+x+(x+1)＝30
3x=30
x=10
x-1=9
x+1=11
numbers are 9,10,11
(f+g)(x) is equivalent to f(x) + g(x)
So that would be (7x-3) + (x²-4x) = x² + 7x - 4x - 3 = x² + 3x - 3
Hope this helps.
