Which of the following represents two lines that are coplanar and do not intersect?
OverLord2011 [107]

Question:

Which of the following represents two lines that are coplanar and do not intersect?

A. Perpendicular

B. Skew

C. Parallel

D. Intersecting

Answer:

Two lines that are co -planar and do not intersect is  Parallel.

Step-by-step explanation:

Two lines are said to be parallel if they lie in the same plane, and are the same distance apart over their entire length.Each line has many parallels. Any line that has the same slope as the original will never intersect with it.  Hence Parallel Lines would never cross, even if extended forever. Technically parallel lines are two coplanar which means they share the same plane or they're in the same plane that never intersect

The following linear equation represents the line of best fit for the following scatter plot
Burka [1]

Answer:

C) 28.5 home runs

General Formulas and Concepts:

<u>Pre-Algebra </u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define </u>

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

<em>We can use this to predict the average of the scatter plot. </em>

hits = x = 200 times

<u>Step 2: Solve for </u><em><u>y</u></em><u> home runs</u>

  1. Substitute [BLF]:                     y = 0.15(200) - 1.5
  2. Multiply:                                  y = 30 - 1.5
  3. Subtract:                                 y = 28.5

Remember that this is only a <em>prediction.</em> Actual data can vary. The best line of fit tells us that if a player hits 200 times, we would get approximately 28.5 home runs.
