Answer:
Its 3
Step-by-step explanation:
Summaation of a sequence
or see a smaller scale
from 1 to 10
notice
1+10=11
2+9=11
etc
5+6=11
10/2=5
there are 5 pairs
5*11=55
so
1 to 100
1+100=101
2+99=101
...
50+51=101
100/2=50
there ar 50 pairs
50 times 101=5050
the sum is 5050

Part A: a histogram
Step-by-step explanation:
Part A:
A histogram would be the best to use since they gave values that are x - y, or a ranged amount for the score.
Part B:
You would set up each value for the scores on the bottom. You would make the number of students on the left in increments of 1 (1,2,3,4,5 etc. )
You would make the first value ( 0-4 ) go up to 4 students. The second value ( 5-9) would go to 5. The third value ( 10-14 ) would go to 2. The fourth and fifth values ( 15-19 and 20-24 ) would go to 3.
