The bottom of the line is a Minimum, the bottom of the rectangle is the Lower-Quartile, the line inside the rectangle is the Median, the top of the rectangle is the Upper-Quartile, the top of the line is the maximum.
Here is what I estimate the values to be given the positions of the line (may be off by 3-4).
Group 1:
- Lower Quartile: 37
- Median: 41
- Upper Quartile: 50


Group 2:
- Lower Quartile: 60
- Median: 80
- Upper Quartile: 92

We can tell A and C are obviously wrong. I favor choice B over D because the Lower Quartile of Group 2 is closer to the 20s than 10s away from the Lower Quartile of Group 1.

A homeowner called in a painter to paint the walls and ceiling of one bedroom. His bedroom is 18ft. long, 12 ft. wide, and 8 ft.
Morgarella [4.7K]
Find total surface area (18*12)*2+ (18*8)*2+ (12*8)*2=     192 +288 432+288+192= 912
then subtract surface area of doors
(3*7)2=42   then subtract windows 3*5(3)=45 then subtract the floor 18*12=216
912-42-45-216= 609 sq ft  he should only need  2 and a small portion of a third to paint your room  i believe what his math must have been was 18*12*8=1728 then subtract -42-45-216 for the floor windows and doors to get 1425 and even then he underestimates with his inaccurate figures 
so first 609 sq ft  he should only need  2 and a small portion of a third to paint your room and 2 get a new painter bcus this guy cant math hope i helped if so give brainliest answer-J (:

nevsk [136]

The answer is B part

As the requirement for the student is either a senior or one who studies maths or both.

So, just add the values within the two venn circles divide it by total no of values.

=> 240+40+110/240+40+110+840

=> 360/1200

write in point-slope form an eauation of the linr thag passes through the givin point and has the givin slope​
Tanya [424]
It’s hard to completely answer without a graph or coordinates, but I do believe that point slope form is y-y1=m(x-x1). Plug in your slope for m. After that, plug in your x coordinate in the appropriate place as well as your y coordinate. Solve from there
