Robert and Makayla are on the student council at their high school. They both want to go to a dinner where student council representatives from other
schools will participate. However, only one student per school can go. How
can a fair decision be made about who goes to the dinner?
Select all that apply.
A. Ten cards have different numbers. Each student picks a card at
random. The student who picks the lower number wins.
B. Roll a number cube. If it lands on 1, 2, 3, or 4, Robert wins.
Otherwise, Makayla wins.
C. Give the students a math problem. The student who is first to
solve the problem wins.
D. Toss a coin twice. If both tosses are heads or both tosses are
tails, Makayla wins. If one is heads and one is tails, Robert wins.

A and D

Step-by-step explanation:

It just is

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

segment bisector

step-by-step explanation:

line segment bisector. definition: a line, ray or segment which cuts another line segment into two equal parts. try this drag one of the orange dots at a or b and note the the line ab always divides the line pq into two equal parts.
