Before you can draw a trend line in your data, you should have a given data at hand. And then draw the trend line or line of best fit.
1. Plot your data in a graphing paper or excel.
2. Make sure that your plotted data has a solid mark to indicate the points in the graph.
3. Divide your data points by labeling x at the center, at the farthest part of your line (left or right diagonally).
4. If you feel that the data are now finely divided, then construct a line base on the x marks you're placing
5. Then you will notice how far or near your date points are by simply looking at the points near the constructed line that you created.
Answer:
You can use a calculator for the decimal operations, but practice some by hand because on the quiz and the test you will not have a calculator.
Step-by-step explanation:
Answer:
Step-by-step explanation:
P(x)=S(x)-C(x)
0.8=9-C(x)
C(x)=9 -0.08
C(x)=8.92
Answer:
29.15 km
Step-by-step explanation:
Given;
George walks; 25km west and then 15 km south
Resolving the directions to x and y axis;
North and South represent positive and negative y axis.
East and West represent positive and negative x axis respectively.
25km west
Rx = -25 km
15 km south
Ry = -15 km
The resultant displacement from the house is;
R = √(Rx^2 + Ry^2)
Substituting the values;
R = √((-15)^2 + (-25)^2)
R = √(225+625)
R = √(850)
R = 29.15 km
Therefore, he is 29.15 km from house
9+(-6) I think that this might work.
