Answer:
16 m^2
Step-by-step explanation:
Area of triangle = (Base * Height) / 2
Area of triangle = ( 8 * 4 ) / 2
Area of triangle = 16
I will find the radius first
2pi(r) = 7pi
Divide 7pi by 2pi
Hence radius is 3.5m
Now the area pi(r^2)
Pi(3.5^2)
The area of the circle is 38.48 or 49/4 pi
AREA = 49/4pi or 38.5m^2 to one d.p
You have to round the number
Answer:
6/7 ≈ 85.7%
Step-by-step explanation:
The probability that a 0 was transmitted and received is 0.5·0.9 = 0.45.
The probability that a 1 was transmitted and a 0 received is 0.5·0.15 = 0.075.
Then the probability that a 0 was received is 0.45 +0.075 = 0.525.
The probability of interest is ...
p(0 transmitted | 0 received) = p(0 transmitted & received)/p(0 received)
= 0.45/0.525 = 6/7 ≈ 85.7%
