elena-s [515]

Answer:

x = 638

y = 1190 - 638 = 552

Step-by-step explanation:

Let x = premium seats

let y = regular seats

x + y = 1190 (ten were not sold

30x + 20y = 30180 (amount collected

now multiply the first equation by 20 and subtract

20x + 20y = 23800

30x + 20y = 30180

-10x = -6380

x = 638

y = 1190 - 638 = 552

check it by multipying x and y by their price to see if you come up with the correct amount

Hope this helps

viva [34]

Answer:

(a) 495, (b) 210

Step-by-step explanation:

Total number of persons = 12

number of openings = 8

number of women = 7

number of men = 12 - 7 = 5

(a) Number of ways to select the 8 persons

$C_{8}^{12}\textrm{}\\\\= \frac{12!}{8!\times 4!}\\\\=495$

(b) Three are men

So, 3 men and 5 women

The number of ways are

$C_{3}^{5}\textrm{} \times C_{5}^{7}\textrm{}\\\\= \frac{5!}{3!\times 2!}\times \frac{7!}{5!\times 2!}\\\\=210$
