Answer:
Your friends data
Step-by-step explanation:
The rule of statistics is: the more exact the data, the better.
Here it seems that you got less precise data, as you can see. This also causes the possibility of mistakes.
This is because when you have data that is more exact, you get a better estimation for mean, median, etc. This can help make patterns in your data.
This means that your friend had better data than you.
Hope this helped!
Answer:
The equation is;
y = 20x + 150
Step-by-step explanation:
Firstly, let us identify the coordinates
(area, cost of area)
We start by getting the points;
(25,650) and (40,950)
The slope will be;
m = (y2-y2)/(x2-x1)
m = (950-650)/(40-25)
m = 300/15 = 20
So the partial equation is;
y = 20x + c
To get the value of c which is the y-intercept, we make use of any of the two points
650 = 20(25) + c
650 = 500 + c
c = 650-500
c = 150
Answer:
see below
Step-by-step explanation:
8+3m= -7
Subtract 8 from each side
3m+8-8= -7-8
Combine like terms
3m= -15
Divide each side by 3
3m/3 = -15/3
m = -5
Check
8+3m= -7
8+3(-5) = -7
8-15 = -7
-7 = -7
m = -5 is the solution
