During an exploratory activity, a student measured the diameter and circumference of several circular objects. She recorded her data in the table below. What equation best represents this data?
y = 6.28x
y = 3.14x + 6.28
y = 3.14x
y = 6.28x + 3.14
Answers
Answer:
y=3.14x
Step-by-step explanation:
if you graph this on a calculator you can just visually see what line lines up with all the points. but you can also plug in one of the points into the equations to see if its true or not and if its true choose that equation. like use the first points (2, 6.28) and plug them into the equations and see which one is true.
The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.
Given that, a student measured the diameter and circumference of several circular objects.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)
From the table we have (2.0, 6.28) and (5.3, 16.64)
Now, slope = (16.64-6.28)/(5.3-2.0)
= 10.36/3.3
= 3.14
Substitute m=3.14 and (x, y)=(2.0, 6.28) in y=mx+c, we get
6.28=3.14(2.0)+c
c=0
Substitute m=3.14 and c=0 in y=mx+c, we get
y=3.14x
The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.

Pine Hill Middle School has 300 students. In
Zoey's class, two out of five students belong to
a club. Use this ratio to predict how many
students in the school belong to a club.
Answers
Step by step explanation
There are 120 students in the school Pine Hill Middle School who belong to a club.
What is a ratio?A ratio describes a comparison between two or more quantities in simplest form.
Given that Pine Hill Middle School has 300 students.
Also given two out of five students belong to a club.
∴ We can conclude that (2/5)th of the total students belong to the club which is numerically,
= (2/5)×300.
= 120 students.
We can also solve this by ratios if in a total of 5 students 2 students belong to a club that means 3 students doesn't belong to the club and their ratio is 2:3.
∴ The no. of students belonging to the club is 2/(2+3)×300.
= (2/5)×300.
= 120 students belong to the club.
