A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 70 p

nikklg [1K]

X = large boxes and y = small boxes

x + y = 70.....x = 70 - y
60x + 65y = 4300

60(70 - y) + 65y = 4300
4200 - 60y + 65y = 4300
5y = 4300 - 4200
5y = 100
y = 100/5
y = 20 <=== the small boxes weigh 20 lbs

x + y = 70
x + 20 = 70
x = 70 - 20
x = 50 <== and the large boxes weigh 50 lbs

Tasya [4]

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 =

= $\binom{6}{4}\times\binom{6}{4}$

= $\frac{(6!)}{(2!)(4!)}\times \frac{(6!)}{(2!)(4!)}$ = 225

(2) chose 5 accounting majors from 6 and chose 3 finance majors from 6 = $\binom{6}{5}\times\binom{6}{3}$

= $\frac{(6!)}{(1!)(5!)}\times\frac{(6!)}{(3!)(3!)}$ = 120

=

(3) chose 6 accounting majors from 6 and chose 2 finance majors from 6 = $\binom{6}{6}\times \binom{6}{2}$

= $\frac{(6!)}{(6!)(0!)}\times\frac{(6!)}{(2!)(4!)}$ = 15

Then total no of ways = (1) + (2) + 3

= 360
