Mrs. cugini collected data on the hand span length and height of each of her Algebra 1 students.
dem82 [27]
<h3>a. slope = \displaystyle m=\frac{15}{2}</h3><h3>b. slope = m = positive = positive correlation =  two sets of data increase together</h3><h3>Further explanation</h3>

Scatter plot shows the relationship between data

We can use Regression to make lines on the chart or you can also make lines with the principle as close as possible to all points

Regression

\displaystyle m=\frac{N\sum (xy)-\sum x\sum y }{ N\sum (x^2)-(\sum x)^2}

Because data is in the form of numbers from the hand span length and height of each of students. not displayed clearly, then we make a line directly by making points on the graph above and below the line as much as possible to be balanced

We specify 2 points that are crossed by a line, for example:

(6.45) and (8.60)

slope (m) = change in y / change in x

\displaystyle m=\frac{60-45}{8-6}\\\\m=\frac{15}{2}

Slope has a positive value, and shows a positive correlation where the tendency of the number rises simultaneously, or can be concluded:

<em>tall students will have the long hand span length too</em>

Hey! I need this pretty fast- just do the first one though! Thank you! :)
Karolina [17]

Step-by-step explanation:

A. part 1: $1.49 for 6 pencils

1 pencil would cost $1.49 / 6 = $0.24833(5s.f.) = $0.25 (nearest cent)

part 2: $4.60 for 20 pencils

1 pencil would cost $4.60 / 20 = $0.23

best value: part 2 (20pencil pack)
