Answer:
10%
Step-by-step explanation:
Choices: 2,3,4,5,6 for a total of 5 cards
odd numbers: 3,5
P (odd number) = odd options/ total
=2/5
Keeping the odd card ( lets say 3)
Choices: 2,3,4,6 for a total of 4 cards
odd numbers: 3
P (odd number) = odd options/ total
1/4
P(odd, no replacement, odd) = 2/5 * 1/4 = 2/20 = 1/10
Changing to a percent = 1/10 *10/10 = 10/100 = 10%
The first answer would be 10
the second answer would be 2.50
i wouldn’t be able to know the third one without knowing the options

Answer:
-6
Step-by-step explanation:
3n = n² - 54
n² - 3n - 54 = 0
n² - 9n + 6n - 54 = 0
n(n - 9) + 6(n - 9) = 0
(n - 9)(n + 6) = 0
n = 9 , -6
