Answer:
1st option
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use (3, 8 ) , that is x = 3 when y = 8 , then
8 = 
( multiply both sides by 3 )
24 = k
y = 
← equation of variation
The answer is C. The 4th period class should get the reward. Though the medians are the same, the first and third quartiles are higher, so the students did better on average than in the 2nd period class.
I believe it’s the answer is A
B because 4.25 (decimals are easier for me) then you times by 3=12.75
but multiply it by 1.25 which equals 15.94
