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 = $1^2-\frac{\sqrt{3} }{4}-\frac{\pi}{12}*2$

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