The coordinates for point a are (-3,5)
The first point tells you the x value and the second tells the y value
Ah well this would look like 2(30) + 30 = 90 aka 2L + W = 90
Let's let x = the number of workers making $75 per day
Then that would mean (60 - x) would be the number of workers who make $100 per day.
Now the average salary, which needs to be 80, can be found by adding all the salaries of the 60 workers and dividing by 60. The following equation can model this problem:
[75x + 100(60 - x)]/60 = 80 simplify the left side of the equation
(-25x + 6000)/60 = 80 multiply both sides by 60
-25x + 6000 = 4800 subtract 6000 from both sides
-25x = -1200 divide both sides by -25
x = 48 recall we set 'x' to equal the number of workers making $75 per day
And there you have it! Hope this helps..
You move the decimal 3.4, 2 places to the right and get 340 then you move the decimal 4.37, 2 placeto the right and you multiply 340 and 437 and you get 14858 and you move 3 decimal place to the left because you moved 3 decimal place so you have to move it back and you get 14.858
Outliers can affect the slope of a line of best fit.
Step-by-step explanation:
Outliers are observed data points which are far from the least-squares line.They contain large errors.They occur as a result of incorrect data.Outliers have a big effect on the slope of a regression line.
