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.
a)Describe the association between the number of working office computers and the total mass of printer paper used per day.
1 answer:
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.
<u>Explanation:</u>
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:
(–3, –2)
Step-by-step explanation:
A linear equation is an equation in the form y = mx + b, where m is the slope of the line and b is the y intercept.
Equation A is represented by the points:
x: -5 -2 0 1
y: -4 -1 1 2
Equation A can be gotten by picking any two pair of points. Let us use (-5, -4) and (0, 1). We use this formula:
Equation B is represented by the points:
x: -6 -3 3 6
y: -4 -2 2 4
Equation B can be gotten by picking any two pair of points. Let us use (-6, -4) and (3, 2). We use this formula:
The solution to the system of equations is gotten by solving y = x + 1 and y = (2/3)x simultaneously.
Substitute y = (2/3)x in y = x + 1:
(2/3)x = x + 1
2x = 3x + 3
x = -3
Put x = -3 in y = (2/3)x
y = (2/3) (-3) = -2
Hence (-3, -2) is the solution
Answer:
diameter =7 cm
Step-by-step explanation:
circum=2pi×r
2×pi×r=22
2×22÷7×r=22
r=22×7÷44
r=7÷2
r=3.5
d=2×r=2×3.5=7
