12,500 / 100 = 125 125 x 4.5 = 562.5 562.5 x 4 = 2250
2250 + 12,500 = 14,750 He paid back a total of $14,750. Hope this helps :)
13. 44 + 40 = 84
14. 15 + 81 = 96
15. 13 + 52 = 65
16. 64 + 28 = 92
Answer:
The correct answer is first option
u² - 11u + 24 = 0
When u = (x² - 1)
Step-by-step explanation:
It is given that,
(x² - 1)² - (x² - 1) + 24 = 0
<u>To find the correct answer</u>
Substitute u = x² - 1
The equation becomes,
u² - 11u + 24 = 0 Where u = (x² - 1)
Therefore the correct answer is first option
u² - 11u + 24 = 0
When u = (x² - 1)
Step-by-step explanation:
n(S) = 25
Assume that O : odd numbers and E : even numbers,
n(O) = 13
n(E) = 25-13 = 12
P(OO) = P(O) x P(O)
= 13/25 x 12/24
(because without replacing so the number of balls left decreases)
= 13/25 x 1/2
= 13/50
