Answer:
Step-by-step explanation:
hello :
r+b=7... (*)
3.75r+2.75b=22.25.... (**)
use (*) : r = 7 - b
put this value in (**) :
3.75(7 - b)+2.75b = 22.25
26.25 -375b +2.75b = 22.5
-375b +2.75b = 22.5 - 26.25
- b = -3.75
so : b = 3.75
but : r = 7 - b
r = 7 - 3.75
r = 3.25

Answer:
The third quartile would be <u>39</u>.
Step-by-step explanation:
• Since the numbers are already in order, the next step would be to find the median:
- The <u>median</u> is the middle number; found by ordering all data points and picking out the one in the middle.
• The <u>first quartile</u>, is denoted as Q1 and is the middle number that falls between the smallest value of the data set and the median.
- The first quartile would be 24.
• The <u>third quartile</u>, is denoted as Q3 and is the median of the upper half of the data set.
- The third quartile would be 39.

Answer with explanation:
A regular polygon is simple closed geometrical shape, only made up of line segments.
And Regular Tessellation, is geometrical shape, made up of regular polygons having, 3 ,or 4 or 6 sides.
It is combination of, only single kind of polygon,either, polygon having 3 sides, or ,4 sides or 6 sides.
→Regular polygon having 3 sides is Called Equilateral Triangle.
→Regular polygon having 4 sides is Called Square.
→Regular polygon having 6 sides is Called Regular Hexagon.
⇒Regular polygon having , 8 sides will not form a regular tessellation.
