Answer:
Recall that probability is given as; the number of required outcome over the number of total possible outcome.
The probability that a transmitter receives the signal being sent by itself is given as 
.
when there are n transmitters, the probability will be given as 
Step-by-step explanation:
Probability simply the likelihood of an event occurring or not occurring.
Probability therefore is given as; the number of required outcome over number of possible outcome.
In the case of the first part above we have the number of required outcome to be at least one divided by the number of possible outcome which is 3.
while in the second part we have the number o possible outcome to be n.

Answer:
b. 5x + 4y = 80
Step-by-step explanation:
Let us assume the remaining balance left be Y
and, the number of songs purchased be X
Given that
Wins a gift card of $20
And, the songs purchased is 16
Now if we take the fraction
= 20 ÷ 16
= 5 ÷ 4
So if we reverse this fraction
So it could be 5x and 4y
And, the amount that would come is
= $20 × 16 ÷ 4
= 80
So, the equation is 5x + 4y = 80
Hence, the correct option is b.
Answer:
width: 7.5
length: 22.5
Step-by-step explanation:
width: x
length: 3x
Perimeter = 2L + 2W
60 = 2(3x) + 2x
60 = 6x + 2x
60 = 8x
x = 7.5
width: x = 7.5
length: 3x = 3(7.5) = 22.5
There is no solution. 2(x-1)^2 = 3-5 (x-1)^2 = -1 you will get an imaginary solution
