The mean  = sum of all the measurements / number of measurements (n)

                 =  (5 + 3 + 3 + 8 + 8)  / 5

                 =   27 / 5

                 = 5.4  Answer

Answer:

Step-by-step explanation:

a1 = 3;

a2 = 2(a1 - 2 ) = 2(3-2) = 2

a2 = 2

a3 = 2(a2-2) = 2(2-2) = 0

a3=0

a4 = 2(a3-2) = 2(0-2) = -4

a4 = -4

a5 = 2(a4 - 2) = 2(-4-2) = -12

a5 = -12

Suppose a square ABCD has a side length of 1 unit. The arcs BD and AC are circular arcs with centers at A and D, respectively. F
Likurg_2 [28]

Answer:

1-\frac{\sqrt{3} }{4}-\frac{\pi}{6}

Step-by-step explanation:

The missing figure is shown in the attachment

The area of the shaded region = Area of Square - (Area of sector AOB + Area of equilateral  triangle BOC + Area of sector COD)

Area of Sector AOB=Area of Sector COD=\frac{30}{360}*\pi*1^2=\frac{\pi}{12}

Area of equilateral triangle =\frac{1}{2}*r*\frac{\sqrt{3} }{2}*r=  \frac{1}{2}*1*\frac{\sqrt{3} }{2}*=\frac{\sqrt{3} }{4}

Area of shade region =1^2-\frac{\sqrt{3} }{4}-\frac{\pi}{12}*2

1-\frac{\sqrt{3} }{4}-\frac{\pi}{6}
