Answer:
The fraction of students who likes soccer or basketball is 7/10.
Step-by-step explanation:
In this case we have two groups of students, the group a is the one that prefers soccer, while the second group is the one that prefers basketball. We then need to find the fraction that represents the students that are in either group, in these cases we need to take the fractions of each group and sum them. So we have:
soccer OR basketball = soccer + basketball
soccer OR basketball = 2/5 + 3/10
Through LMC we have:
soccer OR basketball = (2*2 + 3)/10 = (4 + 3)/10 = 7/10
The fraction of students who likes soccer or basketball is 7/10.

Answer:
The constant of variation is $1.50
Step-by-step explanation:
Given
Point 1 (1,2)
Point 2 (5,8)
Required
Constant of Variation
Though the graph would have assisted in answering the question; its unavailability doesn't mean the question cannot be solved.
Having said that,
the constant variation can be solved by calculating the gradient of the graph;
The gradient is often represented by m and is calculated as thus

Where

By substituting values for x1,x2,y1 and y2; the gradient becomes




Hence, the constant of variation is $1.50
