Box plot allows us to determine the mean, the largest or the lowest number in the data set as well as the quartiles in the data. In this case, from the given figure, median is equal to 18, the range is equal to 21-15 equal to 6. The 25th percentile is equal to17 while the 75th is equal to 20. IQR then is equal to 20-17 equal to 3.

6 50 36 300
8 35 64 280

∑x = 30; ∑y = 291; ∑x^2 = 220; ∑xy = 1,342; n = 5
The <span>least squares regression line equation is given by y = bx + a = -10.1x + 118.9.</span>
Given that the line passes through points (-1,3) and slope 2, the equation will be given by:
m(x-x1)=y-y1
where m is the slope.
thus plugging the values we get:
2(x-(-1))=y-3
2(x+1)=y-3
2x+2=y-3
thus
y=2x+2+3
y=2x+5
thus the equation of the line is y=2x+5
thus when x=0, y=5
hence another point is (0,5)
Answer:
Choice A
Step-by-step explanation:
The endpoints are (-3,-1) and (7,4).
Since it's asking for the domain, you look at the x values which is -3 and 7.
Answer:
(0, 3), (4, 9), (6, 9), (7, 17)
