Answer:
h = 2A/b
Step-by-step explanation:
multiply both sides by 2
2A = bh
divide both sides by b
2A/b = h
• We are told that the average height : Mean () = 65
,
• Standard deviation : SD () = 2.2
• 95 % 0f women height range = +- 3
= 65 +-3( 2.2)
= {65 + 6.6 ; 65 -6.6}
= {71.6 ; 58.4}
• This means that 95 % 0f women height will range between ( 58.4 ) and (71.6 )
12/25 * 100 = 48%

Answer:
(a) the size of each exterior angle 360/10=36
(b) the number of sides of the polygon. 10
Step-by-step explanation:
Each interior angle of a regular polygon is 4 times each exterior angle
∴sum of interior angles: (n-2)*180=4*360
n-2=8
n=10
(a) the size of each exterior angle 360/10=36
(b) the number of sides of the polygon. 10
