Answer:

1 ; 7 /17

Step-by-step explanation:

17 balls numbered 1 through 17

Picking without replacement :

If the second ball picked = 4

P(first ball has a smaller number)

Numbers less Than = (3, 2, 1)

P(number less than second ball Given 4 is drawn for second ball) :

= (3/17 * 1/16) ÷ (3/17 * 1/16) +) 14/17 * 0)

= (3 / 272) / (3 /272) * 0

= 3 / 272 * 272 / 3

= 1

2.)

(8/17 * 7/8) ÷ (8/17 * 7/8) + (9/17 * 1/17)

7/17 ÷ (7 /17) + 10/17

7 /17 ÷ 17/17

7/17 ÷ 1

7 /17

What integer represents w? 9 : 4 = 27 : w
joja [24]

Answer:

12

Step-by-step explanation:

This is because to get 9 to 27 you have to multiply 9 by 3, therefore you have to multiply 4 by 3 due to the fact what you do to one side you have to do to the other to make it all equal:

9 x 3 = 27

4 x 3 = 12

ratio- 9 : 4 = 27 : 12

have a nice night! Hope this helped
