Answer:
Total no of ways can the fund raising committee be formed if at least 4 accounting majors are on the committee. = 360
Step-by-step explanation:
Given -
A business organization needs to make up a 8 member fund-raising committee.
The organization has 6 accounting majors and 6 finance majors .
Total no of ways can the fund raising committee be formed if at least 4 accounting majors are on the committee.
(1) chose 4 accounting majors from 6 and chose 4 finance majors from 6 =
= 
= 
= 225
(2) chose 5 accounting majors from 6 and chose 3 finance majors from 6 = 
= 
= 120
=
(3) chose 6 accounting majors from 6 and chose 2 finance majors from 6 = 
= 
= 15
Then total no of ways = (1) + (2) + 3
= 360
Using multiplication rules, it is found that the result of the multiplication will be a negative number.
<h3>What are multiplication rules?</h3>
- When two numbers of the same signal are multiplied, the result is positive.
- Hence, when an even number of negative numbers are multiplied, the result is positive. If an odd number is multiplied, the result is negative.
Hence, in this problem we have that:
- The result of the multiplication of the 13 negative integers is negative.
- The result of the multiplication of the 18 positive integers is positive.
- The multiplication of both results is the multiplication of a negative by a positive, hence it is negative.

Answer:
x = -2/15.
Step-by-step explanation:
Finding the second derivative:
f'(x) = 15x^2 +4x - 3
f"(x) = 30x + 4
30x + 4 = 0 for a point of inflection
x = -4/30 = -2/15
So 30x + 4 is negative up to x = -2/15 and positive thereafter.
So the curve passes from concave downward to concave upward at x = -2/15.
