Answer:
37
Step-by-step explanation:
Before we find quartile, we have to arrange the data set in order first from least to greatest which this problem has already arranged the data for us.
Next, proceed with the calculation. The formula for finding position of quartile is:
Where 
means the rth quartile, N means number of data set. Since we want to find the third quartile, substitute r = 3 and there are 11 data so substitute N = 11:
So the position of third quartile is at 9th position which is 37.
Henceforth, the third quartile is 37.
Answer:
Step-by-step explanation:
What is the question? If you want to know how to graph this equation, it's usually easiest to start with the intercepts, i.e., the points where the line crosses the axes.
y = ½x + 3 tells you that the line crosses the y-axis at (0,3), so plot that point.
Then let y = 0 and solve for x.
0 = ½x + 3
x = 6
The line crosses the x-axis at (6,0), so plot that point as well.
Then draw the line passing through those two points.
Answer:
- As x approaches infinity, f(x) approaches infinity.
- As x approaches negative infinity, f(x) approaches 0.

Answer:
3m-5
Step-by-step explanation:
combine like terms
Let x be the number of refrigerators
Y be the number of pianos
So the inequality:
300x + 475y < 7100
So substitute 12 and 8 to the inequality
300(12) + 475(8) < 7100
3600 + 3800 < 7100
7400 < 7100 is not true
So it will overload the truck
