Answer:
D). Y = 4x -6
Step-by-step explanation:
Let's get the gradient of line MN
Gradient= (y2-y1)/(x2-x1)
Gradient=( 6-3)/(-7-5)
Gradient= 3/-12
Gradient= -1/4
For a line to be perpendicular to line MN , it gradient multiplied with line MN gradient will be equal to -1
MM'= -1
M = gradient of line MN
M' = gradient of the unknown line
MM'= -1
-1/4M'= -1
M' =( -1*4)/-1
M' = 4
So the line will have a gradient of 4
That is, the equation well be in the form of
Y= 4x +c
Where c can be a positive or negative intercept or constant.
The correct option is
D). Y = 4x -6
Answer:
1. How many packages are delivered each hour.
2. Find the correlating variable on the graph.
3. 105 packages
4. If the truck driver delivers 15 packages an hour. Divide 120 by 15 to get 8 hours. 120/15= 8 hours to deliver 120 pqckages.
It would be zero
See how the Y are the same so if you were to graph it you would get a flat line and it wouldn't be undefined cause that when the X has the same value.
In statistics, thre are basically two types of data: qualitative and quantitative data
<span>Qualitative data is information about qualities; information that can't actually be measured. While quantitative data are data that can be measured.
Therefore, the </span><span>name is given to the type of data that is descriptive rather than numerical</span> is qualitativre data.
