Jeff drew a line through (0, 0) and (7, 7) and said it was the line of best fit for the data.

Part A: Explain why Jeff's line is NOT the best fit.
Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?

Jeff Drew A Line Through (0, 0) And (7, 7) And Said It Was The Line Of Best Fit For The Data. Part A:

Answers

Answer 1

Answer:

The line of best fit would not be right because there would be a big gap of space. The line should be the cooardinate 7,3 as this covers the line and the cooardinate 7,7 is an outlier. The new line is more accurately placed

Step-by-step explanation:

Answer 2

Answer:

The actual line of best fit would be from (0, 0) to (7, 4), this is because it covers majority of the points. All the other points are just anomalies. Moreover, Jeff's line is NOT the line of best fit because it is not accurate and is out of place. Furthermore, the actualy line of best fit is 3 places lower on the y-axis then Jeff's line of best fit.

Answer:

C = -13.78

Step-by-step explanation:

Answer:

c = -13.78

Step-by-step explanation:

21.2x + c =5.3(4x - 2.6)

Use distributive property: a*(b + c) =  (a*b) + (a * c)

21.2x + c = 5.3*4x - 5.3*2.6

21.2x + c  = 21.2x - 13.78

Now to find the value of c, isolate 'c'. So, subtract 21.2x form both sides

21.2x + c - 21.2x = 21.2x - 13.78 - 21.2x

c = -13.78

9. Consider the diagram below. First, solve for x, then y.

Answers

Answer:

x = 59

y = 32

Step-by-step explanation:

x + 78 + 43 = 180

x = 59

y + 59 + 89 = 180

y = 32

Answer:

y = 32; x = 59

Step-by-step explanation:

On the top triangle x+y+89=180 because a triangle's angles add up to 180 degrees, while a quadrilateral's angles add up to 360 degrees.

Angle 89 and the angle below it are supplementary, meaning together they equal 180 degrees.

180 - 89 = 91

So the angle below 89 is 81 degrees.

Now we can subtract the other three angles in the quadrilateral to find the fourth:

360 - (78 + 43 + 91) = 148

So the angle below y is 148 degrees.

Angle y and the angle below it are supplementary, meaning together they equal 180 degrees.

y = 180 - 148

y = 32

All of the angles in a triangle equal 180 degrees:

x = 180 - (32 + 89)

x = 59

7 x 8 56

---------- = -------------

50 x 8 400

∴ Yes, Zack is correct.

5.

We must assume that out of 400 of 150, 000 , about 3 coins will have misprint.

So, we can solve now.

150 000 400 ↔ Think, number of coins divided by misprints.

------------- = -----------

This is called the rule of three.

(150 000 x 3) = 400

------------- = ------------

400 400

1,125 = x

∴ We can predict that there will be 1, 125 misprints in a year.
