Your answer is 472,441 inches
Hope this helps!!!!!!!!
So we know that it must be between 9.5 9.7.. So it has to be 9.56763865854637984... (rounded 9.57) it is irrational because it has no pattern.
The answer is B. You add all the numbers together and divide by the amount of numbers you have to find the mean. The missing height is 62 because 54+57+59+63+66+68+70+58=563
563/9 (amount of numbers you have including the missing height) = 63
3n+2n+4=9n+12
5n+4=9n+12
4-12=9n-5n
-8=4n
Divide both sides by 4
n=-2
You have to pay attention in this:
- The order doesn't matter
- No repetition
- You can not chose all available elements (just 4)
So in this case your formula must be: 9C4= 9!/(4!*(9-4)!) = 126 ways
