if i was talking to a friend on a cell phone and i suddenly couldn't hear them because my phone ran out of battery power, what part of the mathematical model of communication would best explain this problem? scom 2050
The mathematical model of communication would classify this issue as channel capacity.
The greatest quantity of data that can be transferred error-free across a communication channel, such as a mobile phone network, is represented by the channel capacity. In this instance, the phone's battery power determines the channel capacity. As the battery depletes, the phone's ability to send and receive information declines, making it impossible to hear the person on the other end of the line.
Communication models are streamlined depictions of the communication process. Most models attempt to explain both verbal and nonverbal communication, and frequently regard it as a message-exchange. Their purpose is to provide a concise picture of the intricate communication process.

Kylie invested $2,800 in an account paying an interest rate of 5 1/2% compounded annually. Ariana invested $2,800 in an account paying an interest rate of 5 3/4% compounded continuously. After 12 years, how much more money would Ariana have in her account than Kylie, to the nearest dollar?
If Kylie invested $2800 for interest rate of 5(1/2)% compounded annually and Ariana invested $2800 at rate of 5(3/4)% compounded continuously , then after 12 yrs Ariana would have $259.023 more than Kylie.
We have to find the difference in amount of money in the Kylie and Ariana's accounts after 12 years, we need to calculate the value of each investment after 12 years .
For Kylie's investment:
The formula for calculating the future value of a sum invested at a interest rate compounded annually is:
Value = Principle × (1 + r)ⁿ
Where:
Amount invested (P) = 2800 ;
r = interest rate = 5(1/2)% = 11/2% = 5.5% = 0.055 ;
n (time) = 12 years
⇒ Value = $2800 × (1 + 0.055)¹²
= $2800 ×(1.055)¹²
= $5323.38 .
For Ariana's Investment , the rate is compounded continuously ;
the future value can be calculated by using exponential function ;
Value = 2800 × e^(rt) ;
Where: initial investment = 2800 ;
r = interest rate = 5(3/4)% = 23/4% = 5.75% = 0.0575 and
n (time) = 12 ;
⇒ Value = $2800 × e^(0.0575×12)
= $5582.403 .
Therefore , After 12 years Ariana would have $5582.403 and Kylie would have $5323.38, Ariana would have $259.023 more than Kylie.

2. If you throw a single die twice, what's the probability of first getting a 3 and then getting another odd number? A 4/6 simplified 2/3 ??
1. The probability of drawing a red or yellow ball from a standard set of pool balls is 4/7.
2. The probability of first getting a 3 and then getting another odd number is 1/12.
1. Tom has a standard set of pool balls, which includes 7 different colored balls: red, yellow, blue, purple, orange, green, and black. There are 2 red balls and 2 yellow balls out of 7 total balls.
To find the probability of drawing a red or yellow ball, we will add the probabilities of drawing each color separately.
Probability of drawing a red ball = 2/7
Probability of drawing a yellow ball = 2/7
Probability of drawing a red or yellow ball = (2/7) + (2/7) = 4/7
Hence, the probability of drawing a red or yellow ball is 4/7.
2. If a single die twice, the total possible outcomes are = 6x6 = 36.
To find the probability of getting a 3 on the first throw and then getting another odd number on the second throw, we have to find the number of outcomes that meet these conditions and then divide it by the total number of outcomes.
First throw: 3 (1 outcome)
Second throw: odd number (3, 5) (3 outcomes)
So there are a total of 1x3 = 3 outcomes that meet the given conditions.
Thus, Probability = 3/36 = 1/12
So, the probability of first getting a 3 and then getting another odd number is 1/12.

Blank 1:
Question 5 (4 points)
Can you explain how too
The Greatest Common Factor(GSF) of -6x12y and -3xy is 3xy.
To find the greatest common factor (GCF) between two numbers or expressions, we need to identify the highest power of each common factor that divides both numbers or expressions.
In this case, we are trying to find the GCF between -6x12y and -3xy.
The prime factorization of the first expression is -6x12y = -2 * 3 * x * 2 * 2 * 3 * y
And, the prime factorization of the second expression is -3xy = -3 * x * y. The common factors between these two expressions are 3, x, and y.
Since, we are finding the greatest common divisor, we neglect the minus sign to obtain the largest value possible.
We can see that both expressions share a factor of 3, x, and y.
Since the GCF is the highest power of each common factor that divides both expressions, in this case, the GCF of -6x12y and -3xy is 3xy.

The average annual income for five alepeople lat year wa $35,516Four of the alepeople earned thee annual amount: $36,230, 34,500 38,250, and $33,000What wa the annual income of the fifth aleperon?
The answer to the question can be calculated by using the average formula.
The average of a set of numbers is calculated by adding all of the numbers together and dividing the sum by the number of numbers in the set. In this case, the five alepeople earned a total of $176,506, and when divided by 5, the average annual income comes to $35,516.
To calculate the fifth aleperson's income, we subtract the income of the first four alepeople from the total income earned, $176,506. Subtracting the income of the first four alepeople, $36,230 + $34,500 + $38,250 + $33,000, gives us a remaining total of $24,026. When we divide this remaining total by 1, the average annual income for the fifth aleperson comes to $24,026.
Therefore, the fifth aleperson earned an annual income of $24,026. This can be expressed using the formula (total income – (income of aleperson 1 + income of aleperson 2 + income of aleperson 3 + income of aleperson 4)) / number of alepeople = income of fifth aleperson. In this case, (176,506 – (36,230 + 34,500 + 38,250 + 33,000)) / 1 = 24,026.

What formula can be used to determine the cubic feet of a rectangular prism?The base's area and height alone can be used to determine the volume. The two sides of the prism should be measured in the same units. It's best to measure in feet to get cubic feet.
The rectangular prism's volume is equal to the base's area times the height. Length x Width x Height, in cubic units, equals the volume of a rectangular prism.
The base's area and height alone can be used to determine the volume. The two sides of the prism should be measured in the same units. It's best to measure in feet to get cubic feet.
Given the volume rectangular prism = 220 ft²
(x - 5.5)(x + 3)(x) = 220 ft²
(x - 5.5)(x + 3)(x) = 220 ft²
x³ −2.5x² −16.5x = 220
x = 8
Thus, the height of the rectangular prism is 8 ft.

Find the probabilty of obtaining exactly two 2's in five rolls of a fair die.
Answer:
[tex]\rm{ \dfrac{1250}{7776}\; or\; 0.16075\\\\}[/tex]
Step-by-step explanation:
This probability can be determined using combinatorics. The number of ways a sample of size r can be obtained from a larger set of n items is given by the formula
[tex]C(n,r) = \dfrac{n!}{( r! (n - r)! )}[/tex]
We pronounce C(n, r) as n choose r
We are rolling the die five times. So n = 5
On each roll a 2 can appear or not
We need two 2's . This is our r
The number of ways two 2's can appear is given by 5 choose 2
[tex]C(5,2)\\\\= \dfrac{5!}{( 2! (5 - 2)! )}\\\\= \dfrac{5!}{2! \times 3! }\\\\[/tex]
5! is the factorial of 5, 2! is the factorial of 2 and 3! is the factorial of 3
5! = 5 x 3 x 3 x 2 x1
3! = 3 x 2 x 1
2! = 2 x1
[tex]C(5,2) = \dfrac{5\times 4 \times 3 \times 2 \times 1}{((2 \times 1) \times (3 \times 2 \times 1)}\\\\= 10\\[/tex]
You need not go through this laborious process to find 5 choose 2 there are calculators available
So two 2's can appear 10 times.
The probability of getting a 2 on one roll is 1/6 and the probability of not getting a 2 on a single roll is 1-1/6 = 5/6
This works out to a binomial probability which can be computed by the formula
P(x) = C(n, x) pˣqⁿ⁻ˣ
Where x is the number of times the desired outcome succeeds and n the total number of trials
Here x = 2, n = 5, C(5, 2) = 10
[tex]\rm{So\:P(two\:2s\:on\:5\:throws)\: = 10 \cdot \left(\dfrac{1}{6}\right)^2\cdot \left(\dfrac{5}{6}\right)^3\\\\[/tex]
[tex]{= \dfrac{10 \cdot 1\cdot 125}{{6^5}} = \dfrac{1250}{7776} = 0.16075\\\\[/tex]
