Answer: b. It's a fair method because each result is an equally likely possible outcome.
The number of students is same as the number of the sides of the dice. In this scenario, the school principal will roll two dices three times and the number that repeated most will be chosen. For every dice, all number will have equally likely possibility so the randomization is fair(1/6 chance for every student).Rolling the dice >1 times will have a problem because there is a high chance to get draw result. It doesn't have any correlation with fairness though.

Hello from MrBillDoesMath!
Answer:
y = 2x + 2.5
Discussion:
2y -4x = 5 => add 4x to both sides
2y - 4x + 4x = 4x + 5 => -4x + 4x = 0
2y = 4x + 5 => divide both sides by 2
y = 2x + (5/2) => as 5/2 = 2.5
y = 2x + 2/5
Thank you,
MrB
Answer:
The arrangement of the given equation in the slope - intercept form are
1. 
Step-by-step explanation:
Given:
Let A ≡ ( x1 , y1 ) ≡ (-12 , 70)
B ≡ ( x2 , y2 ) ≡ (-4 , 78)
Slope - intercept form :
Where,
m is the slope of the line.
c is the y-intercept.
When two points are given say ( x1 , y1 ) and ( x2 , y2) we can remove slope by
Slope,
∴ 
Now equation of a line for a point ( x1 , y1 ) and having slope m is given as,
Which is in the required form
y = 1x + 82
Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.
