The line which is the best model for the data in a scatter plot is: D. A scatterplot with an x axis labeled, variable A from twenty to sixty in increments of ten and the y axis labeled, variable B from twenty to forty in increments of five with a negative trend line through the middle of eight points.
<h3>What is a scatter plot?</h3>
A scatter plot can be defined as a graph which uses Cartesian coordinates (x-axis and y-axis) to display the values of two (2) variables, with the resulting points revealing any correlation between the data.
<h3>What is a trend line?</h3>
A trend line refers to an statistical (analytical) tool that is used in conjunction with a scatter plot, so as to determine whether or not there's any correlation between a data.
For example, a scatterplot with an x-axis with its points ranging from twenty (20) to sixty (60) in increments of ten (10) while the y-axis has its points ranging from twenty (20) to forty (40) in increments of five (5) with a negative trend line through the middle of eight (8) points i.e above and below the trend line.

Answer:
The 18 ounce bottle costs less per ounce and is the better buy
Step-by-step explanation:
First find the cost per ounce for the 18 ounce bottle
1.10 / 18 =.0611111 per ounce
Then find the cost per ounce for the 38 ounce bottle
2.75 / 36 =.076388888
The 18 ounce bottle costs less per ounce
40,000 = 4 * 10^4
0.000004 = 4 * 10^-6
The power of 10 exactly in between 4 and -6 is -1.
She started with 4 * 10^(-1) which is 0.4.
0.4 * 100,000 = 40,000
0.4/100,000 = 0.000004
The number she started with is 0.4.
The power is 10^5.
