Step-by-step explanation:

Hello :)

By adding up the number of students which we will call a sample size, then dividing it by each individual categorization students picked, we can then figure out the percentage of people who chose that categorization.

18+24+24+54=120

Let's find every percentage.

Popcorn: 18 students choose this choice. Divide that by the total of students to get 0.15, then multiply by 100 to get 15%.

Pretzels: 24 students chose this. Divide by the total to get 0.2, multiply by 100 to get 20%.

Chips: 24 students chose this. Divide by the total to get 0.2, multiply by 100 to get 20%.

Candy: 54 students chose for candy. Divide this by the total amount of students to get 0.45, multiply by 100 to get 45%.

The correct percentage graph is D. Popcorn clearly says that it is 15 percent, and every other section is the correct amount of percentage.

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.

your answer is -9
