In decimal form it's .75 and that's all you can make it
Answer:
0.077
Step-by-step explanation:
From the table :
Number of students aged 31 - 35 = 60
Number of students over 35 = 26
Total number of students = total possible outcomes = 1123
Required outcome = (students aged 31 - 35) + over 35 = 60 + 26 = 86
Probability = required outcome / Total possible outcomes
Probability (at least 31) = 86 / 1123 = 0.0765
= 0.077 (3 decimal places)
Answer:
1. not proportional because it's increasing in different values
2. proportional because the value is increasing equally
3. proportional because the values are increasing in equal amount
4. Proportional because it's increasing in equal amounts
