Choose which line represents the line of best fit.
Lynna [10]

A line which represents the line of best fit is: C. Line B.

<h3>What is a line of best fit?</h3>

A line of best fit is sometimes referred to as a trend line and it can be defined as a statistical or analytical tool that is commonly used in conjunction with a scatter plot, in order to determine whether or not there is any form of association and correlation between a data set.

<h3>The characteristics of a line of best fit.</h3>

In Mathematics, there are different characteristics that are used for determining the line of best fit on a scatter plot and these include the following:

  • The line should be very close to the data points as much as possible.
  • The number of data points that are above the line should be equal to the number of data points that are below the line.

By critically observing the scatter plot using the aforementioned characteristics, we can reasonably and logically deduce that line B represents the line of best fit because the data points are in a linear pattern.

The math club sells candy bars and drinks during football games.
Vinvika [58]

Answer:

The price of candy bar is 75 cents

Step-by-step explanation:

Let c be the price of candy bar and d be the price of drinks

Then according to given statements

60c+110d = 265\ \ \ \ Eqn\ 1\\120c+90d = 270\ \ \ \ Eqn\ 2

Multiplying equation 1 by 2

120c+220d = 530\ \ \ \ Eqn\ 3

Subtracting equation 2 from equation 3

120c+220d - (120c+90d) = 530 - 270\\120c+220d-120-90d = 260\\130d=260

Dividing both sides by 130

\frac{130d}{130} = \frac{260}{130}\\d = 2

Putting d=2 in equation 1

60c+110(2) = 265\\60c + 220 = 265\\60c+220-220 = 265-220\\60c=45\\c = \frac{45}{60}\\c = 0.75

Price of candy bar is $0.75 or 75 cents

Hence,

The price of candy bar is 75 cents
