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.

Hello from MrBillDoesMath
Answer: 6.2 feet
Discussion:
The ladder and the wall form a right triangle. The length of the ladder, 20 in this case, is the hypotenuse of the triangle. Let "x" be the distance between the foot of the ladder and the building. Then from trigonometry,
cos (@) = length of adjacent side/ hypotenuse
or in our case
cos(72) = x / 20 => (multiply both sides by 20)
20 * cos(72) = x.
Using a calculator this becomes
20 * ( .3090) = 6.18 feet (approx) or 6.2 feet , rounded to the nearest foot.
Thank you,
Mr. B
Answer:
A. 46.71
Step-by-step explanation:
I'm going to guess this is a "free-point" question, but here we go.
46.7 can be represented as 46.70, so, understandibly, adding 1 to the hundreths place gives you.
46.71
Hope this helps!
Answer:
7a+4a
we add same term.
a is common for both.
First take common term out
7a+4a = a(7 + 4) (we add same term.
= 11a
