Yes, absolutely! You have correctly identified a good line of best fit and found a point that matches with the 450 thousand. Good job!
You could convert them into improper fractions first. 7 7/8 should become 63/8 and 3 1/4 should become 13/4. Then, change both fractions so they share a common denominator. I'll use 8.
63/8-26/8 = 37/8, which is then converted into 4 5/8.
Hope that helped you.
Answer:
28.3 cm
Step-by-step explanation:
The formula to find the circumference is 2•π•radius. The diameter is 9 cm, so the radius is 9/2 = 4.5 cm. So, the circumference is:
2•4.5•3.14 = 28.26 ≈ 28.3 cm
First, you need to know the coordinates of the points:
If x is 9 stacked bins to the y of 41 inches, the first point is (9,41)
From there, you can determine the other point: (4,26)
Find the slope by subtraction using the formula: y2-y1/x2-x1
(41-26)/(9-4)
15/5
slope is 3
y=3x+b
To find b, substitute one point into the equation. I will use (4,26)
26=3(4)+b
26=12+b
-12 -12
b=14
Your final equation is:
y=3x + 14
