Answer:

Exact area = 24+8pi square cm

Approximate area = 49.1327412287183 square cm

================================================================

Explanation:

The semicircle portion has area of 0.5*pi*r^2 = 0.5*pi*4^2 = 8pi

The largest triangle has an area of 0.5*b*h = 0.5*8*6 = 24

The total exact area is therefore 24+8pi and this is approximately equal to 49.1327412287183 after using a calculator.

Consider a biased coin with the probability of turning up head 0 < p < 1. We flip the coin 10 times and get a sequence of

qwelly [4]

Answer:

Probability of obtaining 6H and 4T = 0.2051

Step-by-step explanation:

Since for a fair coin,

Probability of obtaining Head = 0.5

p = 0.5

q = 1-p = 0.5

Probability of obtaining 6H and 4T = 10C6 (p)^6(q)^4 = 210*0.5^6*0.5^4

P(6H, 4T) = 0.2051
