Answer:
-1
—— = -0.25000
4
Step-by-step explanation:
It's a trick question. There are an infinite number of mixed numbers between 3 and 4 that can multiply to equal 12 (for example, 3 and 3/7 times 3 and 1/2), but there are no mixed numbers between 3 and 4 that can multiply to equal 9. 3 times 3 is not between them but is 3, but that quantity is excluded because 3<x<4. Anything even a small bit above the number 3 would have to be multiplied by 2 and some fraction, which would not be between 3 and 4.

The missing parameters are:




at least
Required
The score in game 5 to make you advance
Mean is calculated as:

So, we have:


The mean must be at least 90.
So, we have:

Multiply both sides by 5


Make Game 5 the subject
