The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.
Step-by-step explanation:
The given is,
Roberto score on math quiz at last week is 74
This week he made an 85 on the quiz
Step:1
Formula to calculate the percentage of increase the score,
× 100...........(1)
From the given,
Final score = 85
Starting score = 74
Equation (1) becomes,
× 100
= 
× 100
= 0.1486486 × 100
= 14.86486 %
≅ 14.87 %
Percentage of increase = 14.87 %

The percentage of increase in Roberto score is 14.87%, if Roberto made a 74 on last weeks math quiz. this week he made an 85 on the quiz.
Answer:
1) 0.30
2) 0.308
Step-by-step explanation:
1)
Interest Frequency
High 30
Medium 40
Low 30
Total frequency=30+40+30=100.
The relative frequency of student with high interest can be computed by dividing the frequency of high interest to the total frequency.
R.f of high interest=30/100=0.30
2)
Monthly Commission Frequencies
600-800 3
800-1000 7
1000-1200 11
1200-1400 22
1400-1600 40
1600-1800 24
1800-2000 9
2000-2200 4
Total frequency=3+7+11+22+40+24+9+4=120
The relative frequency of earning 1600 or more computed by dividing the frequency of earning 1600 or more to the total frequency.
R.f of earning more than 1600=24+9+4/120=37/120=0.308
