A survey was conducted to find out if there is relationship between the number of working office computers and the total mass of printer paper used per day. The scatter plot for the bivariable data and the line of best fit is shown below.

a)Describe the association between the number of working office computers and the total mass of printer paper used per day.

According to the scatterplot, there is a direct relation between the number of working office computers and the mass of print paper. With the increase in one variable, the other will also increase.

Explanation:

A scatterplot is a kind of plot or scientific graph utilizing Cartesian directions to show esteems for normally two factors for a lot of information. On the off chance that the focuses are coded, one extra factor can be shown.

Scatter plots are utilized to plot information focuses on a level and a vertical hub in the endeavor to show the amount one variable is influenced by another. The connection between two factors is called their relationship.

answer: (x)+4-5=-3

step-by-step explanation:

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
