Answer:
He is not correct, the answer is All Real Numbers.
Step-by-step explanation:
When two lines are right on top of each other, the solution set is All Real Numbers that are on both lines because the solution set is the point(s) at which the lines overlap.

Answer: Justin: 21 dollars, Raina: 16 dollars, Cho: 42 dollars.
Step-by-step explanation:
Let's say that Justin has x dollars.
Since Raina has 5 dollars less than Justin, Raina has (x - 5) dollars.
Since Cho has 2 times of what Justin has, Cho has 2x dollars.
In total, they have 79 dollars. So by adding up our quantities, they will equal 79 dollars.
x + (x - 5) + 2x = 79
So: 4x - 5 = 79
So 4x = 84
So x = 21
Therefore Justin has 21 dollars
Since Raina has 5 dollars less than Justin, Raina has 16 dollars
Since Cho has 2 times of Justin, Cho has 42 dollars
Answer:
0.00111
Step-by-step explanation:
Since the modem receiver takes a majority vote of the five
received bits to estimate the input signal, it will only make a wrong decision if 3, 4 or 5 of the 5 bits received are wrong.
Given that the channel changes an input bit to its complement with probability p =1/10 and it does so independently of its treatment of other input bits, the probability of changing 3 bits out of five is 0.1*0.1*0.1 = 0.001, of changing 4 is 0.0001 and of changing 5 is 0.00001
So, the probability that the modem makes a wrong decision is 0.001+0.0001+0.00001 = 0.00111
