100 - 85 = 15%
15% = 6
1% = 0.4
100% = 0.4 x 100 = 40
Answer: There were 40 questions.
Answer:
9r
Step-by-step explanation:
Answer:
x²+ x = 0
x ( x +1 ) = 0
x = -1
x³-25x=0
x ( x² - 25 ) = 0
x² = 25
x = 5
x²=4x
x² - 4x = 0
x ( x- 4 ) = 0
x = 4
4x²-4x=1
4x²-4x - 1 = 0
4 x² - 2x - 2x - 1 = 0
2x ( 2x - 1 ) - 1 ( 2x- 1 ) = 0
2x- 1 ) ² = 0
2x = 1
x = 1/ 2

Answer:
Probability = 0
Step-by-step explanation:
If something happening is impossible, it's probability of occurring is also 0.
A deck of cards only contains 4 jacks.
Thus you can never get 6 jacks out of the deck without replacing the selected card each time.
Since we are not replacing the cards once we pick them, this event is impossible to occur.
