The mean of group A is 26.8 years
Answer:

Step-by-step explanation:
Since this is a degree we going to use the arc length formula

where x is the central angle measure and r is the radius.
The radius is 6 and the central angle is 48 so let plug that in the formula

Multiply 2 pi by 6




Answer:
(6, - 5 )
Step-by-step explanation:
The parabola is symmetrical about x = 4
The point (2, - 5 ) is 2 units to the left of x = 4 ,then
the point 2 units to the right of x = 4 is (6, - 5 )
Since it increases by 6%, that means you times the amount by an EXTRA 6%. I.e. 6220 x 1.06 = $6593.20
