5c four buses carrying 100 high school students arrive to montreal. the buses carry, respectively, 10,20,50, and 20 students.
one of the students is randomly selected. let x denote the number of students that were on the bus carrying this randomly selected student. what is e[x]?
one of the four bus drivers is also randomly selected. let y denote the number of students on that driver's bus. what is e[y]?

answer: i think it is (1,-2)

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

answer: the actual answer is a. good bank will have the least amount in fees per year.

the answer will be $181.5

hope this !
