Answer:
122.5
Step-by-step explanation:
Let the student normal score be 100
In the beginning score increased by 40%
Hence score at the beginning =100+40 = 140%
Now before end score decreased by 25%
Decrease = 25% of 140 = 35
Hence score at the end of month = 140-35 = 105
Average score for the month
= Total of scores of end and beginning month /2
= 
1. 60/1/5 =12 (purple)
2. The theoretical is 1/5 and in the experimental probability the spinner was spun 60 times and 1/5 of those were purple making the theoretical and experimental probability of purple the same
What you will need to do here is take 180 and divide it by 210 which will give you .<span>85714285714
And if you need to round that to the nearest tenth you will get .9 </span>
