Answer:
I need help with this one
Step-by-step explanation:
I suppose that the question is 17.5 %.
To increase an amount by a percentage, the multiplier is given by (100 + %)/100
Therefore, to increase an amount by 17.5%,
the single multiplier is given by (100 + 17.5)/100 = 117.5/100 = 1.175
Answer:
143÷g=g
Kinda easy.
I hope this is what you meant.
And I hope this helps you! ;P
To solve this problem, we should note that there are:
total questions = 100
questions answered correctly = 90
questions that needed additional clues = 10
1. The first question is to find the probability that in the
third question, Mary would need additional clue. Therefore this implies that in
the first and second questions, Mary would answer it correctly. Therefore:
Probability = (question 1 answered correctly) * (question 2 answered
correctly) * (question 3 needed clue)
Probability = (90/100)*(89/99)*(10/98)
Probability = 0.08256 = 8.26%
2. The second question finds for the probability that two
consecutive needs additional clue, therefore:
Probability = (question 1 needed clue) * (question 2 needed
clue)
Probability = (10/100)*(9/99)
Probability = 9.1*10^-3 = 0.91%
483/13 is what I got. You can also convert it to 37 2/13
