Part A: Yes, Triangle DEF and DBC are the same triangle, but DBC is smaller than DEF because it is just a cut off of DEF.
Part B: I am pretty sure it is angle C.
Part C: I am pretty sure it is angle D.
Answer:
for the area of the Circle we use A=πd
A=3.14x12 A=37.68
for a rectangle it is A=ab
A=12x15 A=180
37.68+180=142.32
your answer is 142.32 m 2
The answer should be...
(6,0) !
All you have to do is count 6 spots to the right of the origin.
Answer:
6 times we need to transmit the message over this unreliable channel so that with probability 63/64.
Step-by-step explanation:
Consider the provided information.
Let x is the number of times massage received.
It is given that the probability of successfully is 1/2.
Thus p = 1/2 and q = 1/2
We want the number of times do we need to transmit the message over this unreliable channel so that with probability 63/64 the message is received at least once.
According to the binomial distribution:

We want message is received at least once. This can be written as:

The probability of at least once is given as 63/64 we need to find the number of times we need to send the massage.





By comparing the value number we find that the value of n should be 6.
Hence, 6 times we need to transmit the message over this unreliable channel so that with probability 63/64.
