A group of 17 students participated in a quiz competition. Their scores are shown below: Score 0–4 5–9 10–14 15–19 20–24 Number of students 4 5 2 3 3 Part A: Would a dot plot, a histogram, or a box plot best represent the data shown above. Explain your answer. (4 points) Part B: Provide a step-by-step description of how you would create the graph named in Part A. (6 points)

A dot plot would best describe the data represented, as there isn't much info to present and it is simpler and easier to see than a histogram.

The x-axis of the dot plot would be the test scores, and the y-axis of the dot plot would be how many students got which test scores.

4 dots would fall under 0-4, 5 dots would fall under 5-9, 2 dots would fall under 10-14, 3 dots would fall under 15-19, and 3 dots would fall under 20-24.

10 down (bang1)

5 up

5down (2)

2.5 up

1.25 up

1.25 down (4)

now add them up : )

hoped i lol

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
