Step-by-step explanation:
Let 
The slope of the line through these two points is
So the slope-intercept form of the line passing through the two points is
To find b, we use either point into our equation. Let's use (-1, -8):
Therefore, the slope-intercept form of the equation for the line is
The standard form of the equation can be written as
This is much easier when you use a software like MS Excel. You have to list the points first. These are: (1,3), (2,2.5), (3,4), (4,5), (5,6.5), (6,5.5), (7,7), (8,6), (9,7.5), (10,7) and (11,9).
Do a scatter plot for this points and add a trend line and you obtain the equation of the line fit. The equation is
p=0.6m+2.4
We use this equation to find p when m=12.
p = (0.6×12)+2.4
p = 9.6
Total profit in month 12 would be 9.6 thousand.
Answer:
5 days
Step-by-step explanation:
This questions involves ratios, the job with 30 men can be done in 15 days, so the ratio from amount of men to amount of days the job will take to complete, it is 30:15. If we had 10 men instead of 30, 10 is one-third of 30, so you have to divide by 3 on each side of the ratio to get your answer.
If we do that we get the ratio 10:5.
Meaning that the 5 is the amount of days needed to be taken in order the complete the job.
Hope this helps!
