Answer:
2/5 or .4
Step-by-step explanation:
basically look at the points where the line meets the graph. two points would be 0,20 and 50,40. then count the amount that it changes vertically and then horizontally. +20vertical +50 horizonal giving the slope 20/50. this can then be simplified to 2/5 or the equivalent number .4

Solution: The number of ways we can arrange 3 blue marbles if a set of 5 marbles is selected is:
Therefore, there are 10 ways we could arrange 3 blue marbles.
Answer:
Since we have a^7 on the Numerator and after simplification... No "a" was left in the expression. It simply means that all a's in the numerator was eliminated and 2a's were left in the denominator.
To eliminate a^7 and still have 2a's as a remainder in the denominator... 'n' must be equal to 9
So
n=9
