The answer is C, since the number in the parenthesis represent what is being multiplied every year
The answer is C. x=3 2(3)^3=54
This is a problem of fundamental counting principle. In a
sequence of events, the total possible number of ways all events can performed
is the product of the possible number of ways each individual event can be
performed. So here there is one car in each place so there 4 possible
cars to get the 1st place, 3 possible car for the 2nd
place, 2 possible cars for 3rd place and 1 for the 4th
place. The 4x3x2x1 = 24 different order
What you have to do here is to find a common denominator.
In this case, both 8 and 16 are multiples of 16.
therefore, you've got to multiply the first equation by 2.
1/8*2= 2/16
You've then got to add these together because you've got the same denominator.
2/16+ 3/16= 5/16 (as you don't add the denominators)
If you've meant to put the answer twice in the question, then you've simply got to double it.
Hope this helps :)
