Question

A graph titled Monthly Sales and Advertising Costs has Advertising Costs (1,000 dollars) on the x-axis and sales (1,000 dollars) on the y-axis. A line goes through points (6.4, 117) and (6.6, 120). The slope of the trend line is 15. What does that mean in regard to the data of the scatterplot? Check all that apply. The slope represents the rate of change of the data. Advertising costs increase $15,000 as sales increase by $1,000. Sales increase $15,000 as ads increase by $1,000. A positive slope infers a negative correlation. A positive slope infers a positive correlation.

Answer 1

Answer:

Concept:

A graph, which is a mathematical description of a network, describes the connection between lines and points. A graphs is composed of points connected by lines. It makes no difference how long the lines are or where the points are located. Data relationships are often represented visually using graphs. The purpose of a graph is to convey information that is too large or complex to be adequately stated in language and in a limited amount of space.

Given:

1. Advertising Costs (1,000 dollars) are on the x-axis, and sales (1,000 dollars) are on the y-axis, in a graph titled Monthly Sales and Advertising Costs. The points (6.4, 117) are connected by a line (6.6, 120). The trend line has a 15-degree slope. What does this mean in terms of the scatterplot's data? Check all that apply. The slope represents the rate of change of the data. When sales increase by $1,000, advertising costs rise by $15,000. Ads increase by $1,000, resulting in a $15,000 increase in sales. A positive slope infers a negative correlation. A positive correlation is implied by a positive slope.

find the answers of the given questions

Answer:

The goes through points $(6.4, 117)$ $and$ $(6.6, 120)$

$Point 1 = ( 6.4 , 117)$

$point 2 = ( 6.6 , 120)$

Slope of  trend line  $= ( 6.6 , 120)-( 6.4 , 117)$

                                 $=( 120 - 117) / ( 6.6 - 6.4)$

                                 $= 3/(0.2)$

                                 $= 3 * 10 /2$

                                 $= 30/2$

      the tend line is  $= 15$

The trend line has a $15$ slope.

therefore, The goes through points $(6.4, 117)$ $and$ $(6.6, 120)$ and

The trend line slope is $15$.

=> The slope shows the data's pace of change.

Ads increase by $$1,000$, resulting in a $$15,000$ increase in sales.

=> However, it is reasonable to expect a $$15,000$ rise in sales as the number of adverts increases by $$1,000$. The change in the vertical axis is always greater than the change in the horizontal axis.

A positive correlation is implied by a positive slope.
