First you have to look to see if you can isolate h. to do this you need to divide 2g on both sidesmaking the equation into f/2g=h.
just an extra little fact, we divide the 2g because it was multiplied as 2gh, to move it to the other side you do the opposite to it, therefore it being division :)
Well I'm doing it an easy way but 50% or half of 698 is about 350.
475 is slightly above 350 so the answer would be 68%
Answer: There are 495 possible different sets of answers the could contain exactly 8 correct answers of false.
Basically, we are looking for the number of different ways of selecting 8 objects out of a set of 12 objects. Our objects are answers of false and the set is the test.
This is a combination problem. The formula would be:
12! / (8! x 4!) = 495
Answer:
11,880 different ways.
Step-by-step explanation:
We have been given that from a pool of 12 candidates, the offices of president, vice-president, secretary, and treasurer will be filled. We are asked to find the number of ways in which the offices can be filled.
We will use permutations for solve our given problem.
, where,
n = Number of total items,
r = Items being chosen at a time.
For our given scenario
and
.





Therefore, offices can be filled in 11,880 different ways.
