Answer:
D) (0,9.5) and (10,1.5)
Step-by-step explanation:
a line of best fit is a line that is drawn through the data points on the scatter plot. Option D is the only answer that draws a linear line through the data points.
Option A makes a short line above the points. if the line is not through the points, it doesn't work
Option B is drawing a positive line (as in it's increasing) and therefore cannot work
Option C draws a line below the points and does not represent the line of best fit for this scatter plot
I assume take the z score or it would be about 30% because of the 60, 95, 97.5 rule which has a technical name that I can't remember
Answer:
-32
Step-by-step explanation:
-2^3= -8
-2^2= 4
=-8x4=-32
Answer:
($20/gal)r + ($30/gal)b ≤ $250
r + b ≤ 10 (gallons)
Step-by-step explanation:
Represent the amount of red paint by r and that of blue point by b.
Olivia must cover 5000 ft^2 with paint, which comes out to 5000/500, or 10, gallons total of red and blue paint. The corresponding inequality is
r + b ≤ 10 (gallons)
She has onlyl $250 to spend. Therefore, the following must hold true:
($20/gal)r + ($30/gal)b ≤ $250
The required sysstem of inequalities is thus
($20/gal)r + ($30/gal)b ≤ $250
r + b ≤ 10 (gallons)
