A binary communication channel carries data as one of two sets of signals denoted by 0 (zero) and 1. Owing to noise, a transmitted 0 is sometimes received as a 1, and a transmitted 1 is sometimes received as a 0. For a given channel, it can be assumed that a transmitted 0 is correctly received with probability 0.95 and a transmitted 1 is correctly received with probability 0.75. Also, 70% of all messages are transmitted as a 0. If a signal is sent, determine the probability that a 1 was received.
Answer:
26% probability that a 1 was received.
Step-by-step explanation:
We have these following probabilities:
70% probability that a message is transmitted as a 0.
100 - 70 = 30% probability that a message is transmitted as a 1.
If a message is transmitted as a 0, 95% probability of being received as a 0 and 5% probability of being received as 1.
If a message is transmitted as a 1, 75% of being received as a 1 and 25% probability of being received as a 0.
If a signal is sent, determine the probability that a 1 was received.
5% of 70%(Sent 0, received 1) of 75% of 30%(sent 1 and received 1). So
[tex]p = 0.05*0.7 + 0.75*0.3 = 0.26[/tex]
26% probability that a 1 was received.

Answer:
A: Yes, As more gallons are used the longer the shower is
B: 5 minutes, 20 minutes
C: (30,10), someone who uses 30 gallons of water will be in the shower for 10 minutes
D: I'm going to assume that your teacher wants you to find the slope in which I will use the slope formula and the points (0,0) and (30,10)
(10-0)/(30-0)=1/3=.33333 which means that for every gallon of water used you will be in the shower for .33333 minutes longer
Step-by-step explanation:
A: Yes, As more gallons are used the longer the shower is
B: 5 minutes, 20 minutes
C: (30,10), someone who uses 30 gallons of water will be in the shower for 10 minutes
D: I'm going to assume that your teacher wants you to find the slope in which I will use the slope formula and the points (0,0) and (30,10)

Consider the polynomial function g(x)=-10x^7-9x^5+7x^3-8x.
What is the end behavior of the graph of g?
Answer:
the graph rises to the left and falls to the right.
the answer is B
Step-by-step explanation:
The polynomial function [tex]g(x)=-10x^7-9x^5+7x^3-8x.[/tex]. Option B is correct. When x ---> ∞ , g(x) --> -∞ and when x --> -∞, g(x) --> ∞ .
Given that,
polynomial function [tex]g(x)=-10x^7-9x^5+7x^3-8x.[/tex]
A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
What is range?The Range, it is the set of the values that come out to an outcome for a certain mathematical operation.
Since, In the question, polynomial function [tex]g(x)=-10x^7-9x^5+7x^3-8x[/tex] is given,
When the value of x = (0, +∞)
range of g(x) = (0, -∞)
Whn the value of x = (0, -∞)
range of g(x) = (0, +∞).
Thus, the polynomial function [tex]g(x)=-10x^7-9x^5+7x^3-8x.[/tex]. Option B is correct. When x ---> ∞ , g(x) --> -∞ and when x --> -∞, g(x) --> ∞ .

Which number is the best estimate for the fraction 29/40?
A) 0.5
B) 0.6
C) 0.7
D) 0.8
I know it’s B I just don’t know the explanation for it. Please help me. The question is on desmos
Answer:
Its actually C
Step-by-step explanation:
|So you first divide 29 from 40. You will need to long divide...because 40 cant go into 29. you will put a 0 on the top then you will put a decimal behind the 0 representing your going into the tenths, and then from there you just divide like you usually do.
Hope you get it, if you need more explanation please tell me :)

A system of equations is when there are 2 or more equations. When does a system of equations have no solution? Also, create an example of 2 equations that would demonstrate that situation.
Answer:
Step-by-step explanation:
The solution is the set of points where all the equations intersect. If there is no such point, there is no solution.
For example,
y = 8
y = 6
These are parallel lines with no points in common.

Josh deposited 1500 into a savings account at his nearby bank. The bank’s interest rate is 3%. He does not deposit or withdraw any money for the next 4 years. How much interest will he gain after the fourth year?
Answer:
188.27
Step-by-step explanation:
divide the starting number (1500) by 100 to get 1% then times by 3 to get the new number for tje start of tje next year.
After 1st- 1545
after 2nd year = 1591.35
After 3rd = 1639.1005
After 4th= 1688.273515
what he gained is 1688.273515-1500= 188.273515.
now round to 2 decimals = 188.27

x+5y=17
-4x+3y=24
how to solve this problem
Answer:
okay so x=-3, y=4
Step-by-step explanation:
based off the top of my head -3+5*4=17 and -4*-3=12 12+3*4=24
Answer:
x=-3 ,y=4
Step-by-step explanation:
x+5y=17------(i)
-4x+3y=24------(ii)
use substitution method
x+5y=17
make x subject of the formula
x=17-5y-----(iii)
substitute equation (iii) into equation (ii)
-4x+3y=24
-4(17-5y)+3y=24
-68+20y+3y=24
23y=24+68
23y=92
divide both sides by 23
y=92/23
y=4
substitute y in equation (iii)
x=17-5y
x=17-5(4)
x=17-20
x=-3
