Answer:
The probability of failure of both radios is 0.00003364.
The flight becomes much safer with two independent radios
Step-by-step explanation:
When you have two events A and P with probabilities P(A)=q and P(B)=r, if the events are independent (that is to say, if the occurrence of one event does not influence the occurrence of the other), then
where the event intersection means the probability of the occurrence of both events.
If we call P(A) the probability of a radio failure, as the occurrence of failure of a radio is independent of having another radio, then the probability of the failure of both radios is
(0.0058)*(0.0058) = 0.00003364
So, the probability that a particular flight will be threatened with the failure of both radios is 0.00003364.
Hence the flight becomes much safer with two independent radios

Answer: x = 12</h3>
=====================================================
Explanation:
C is the midpoint of AB. This means AC is half as long as AB
Put another way, AB is twice as long as AC
AB = 2*AC
AB = 2*( AC )
32 = 2*( x/2 + 10 ) .... substitution
32 = 2*(x/2) + 2*10 ... distribute
32 = x + 20
x+20 = 32
x = 32-20 .... subtract 20 from both sides
x = 12
---------
If x = 12, then
AC = x/2 + 10
AC = 12/2 + 10
AC = 6+10
AC = 16
which is half of AB = 32, so it confirms our answer.
