The characteristics of the channel or transmission medium, and other factors related to the specific system being considered.

If we assume that the probability of error (the probability that the decoder will make a mistake) is greater than 0, then the probability that the decoder will know with certainty what the source bit was is 1 minus the probability of error.

Let's denote the probability of error as p_error. The probability that the decoder will know the source bit with certainty (probability of correct decoding) can be expressed as:

P_correct = 1 - p_error

Since we assume that p_error is greater than 0, the probability of correct decoding will be less than 1 but greater than 0.

It's important to note that this is a general concept and the specific value of p_error would depend on the decoding algorithm, the characteristics of the channel or transmission medium, and other factors related to the specific system being considered.

Step-by-step explanation:

one liter is a thousand ml, so u just have to multiply

Given that each side of a square is increasing at a rate of 4 cm/s. At what rate is the area of the square increasing when the area of the square is 64 cm²?We are required to find the rate of increase of the area of a square when its area is 64 cm². Let us begin with what we know about the square.

Let the side of the square be s at any time. Now, when the sides of a square increase, the area of the square also increases proportionally by the square of the length of the sides. Thus, when the side is s, the area is s². Now, when the side of the square increases by ds/dt = 4 cm/s, the side becomes s + ds and the area becomes (s + ds)² or s² + 2*s*ds + (ds)². Now, we need to determine the rate at which the area of the square is increasing. Thus, we differentiate the area with respect to time, t.dA/dt = d/dt(s² + 2*s*ds + (ds)²)We know that the rate of increase of the side of the square is ds/dt = 4 cm/s. Thus, we can  the value of ds in the above equation. dA/dt = d/dt(s² + 2*s*ds + (ds)²)= d/dt(s²) + d/dt(2*s*ds) + d/dt(ds²)Let us differentiate each term separately.= 2s*ds/dt + 2s*ds/dt + 2ds/dt²= 4s*(4) + 2(4)(ds)²On substituting s = 8 and ds/dt = 4 cm/s, we get: dA/dt = 2 * 8 * 4 + 2 * 4 * 4= 64 + 32= 96 cm²/sThus, the rate at which the area of the square is increasing is 96 cm²/s when the area of the square is 64 cm².

Answer:

Step-by-step explanation:

1) Number of nickels = x

Number of quarter = y

x + y = 7   ----------------------(I)

x = 7 - y ------------------------(II)

0.05x + 0.25y = 0.55 -----------(III)

Substitute s = 7 - y in equation (III)

0.05*(7 - y)  + 0.25y = 0.55

0.05*7 - 0.05*y + 0.25y = 0.55

0.35 - 0.05y + 0.25y  = 0.55            {Combine like terms}

0.35  + 0.20y  = 0.55          {Subtract 0.35 from both sides}

  0.2y = 0.55 - 0.35

   0.2y = 0.2       {Divide both sides by 0.2}

        y = 0.2/0.2

y = 1

Substitute y =1 in equation (II)

x = 7 - 1

x = 6

Number of nickels = 6

Number of quarter = 1

2) Number of children tickets = x

Number of adult tickets = y

x + y = 40  -----------------(I)

     x = 40 - y  -----------------(II)

2x + 5y = 170 -----------------(III)

Substitute x = 40 - y in equation (III)

2*(40-y) + 5y = 170

2*40 - 2*y + 5y = 170

80 - 2y + 5y   = 170             {Combine like terms}

80 + 3y = 170                {Subtract 80 from both sides}

       3y = 170 - 80

       3y = 90       {Divide both sides by 3}

         y = 90/3

y = 30

Substitute y = 30 in equation (II)

x  = 40 - 30

x = 10

Number of children tickets = 10

Number of adult tickets =30

Hi Student!

The first step to solving our question is to understand the problem statement and to extract important information that will be useful.  We are told that the local candy shops sells Jelly Beans for $2 a pound and Chocolate Melts for $3 a pound.  We are also told that Kelsi has no more than $12 to spend.  Finally, we are told that the purpose of this question is to write an inequality to capture the scenario.

We know that we have two variables, the variable x for jelly beans and the variable y for chocolate melts.  Creating an inequality we need to capture the total of these two should be no more than $12.  This means that it isn't just less than $12 but that it can also include $12; therefore, we use a less-than-equal sign.

Create an expression

This inequality captures the goal of our expression which is to see how two items combined should be less than the total price that we want to spend.  Let's create a new inequality with updated numbers with our information.

Plug in values

Simplify to just numbers

After plugging in the values, we have a lot of unnecessary information such as the dollars signs or words so we can remove that and just have the numbers to show that is going on.

Therefore, our final answer is that the inequality that best represents this scenario is \(2 x + 3y\leq 12\)

Answer:

The law of demand says that at higher prices, buyers will demand less of an economic good. The law of supply says that at higher prices, sellers will supply more of an economic good. These two laws interact to determine the actual market prices and volume of goods that are traded on a market.

Supply is generally considered to slope upward: as the price rises, suppliers are willing to produce more. Demand is generally considered to slope downward: at higher prices, consumers buy less. ... The relationship between the supply and demand for a good (or service) and changes in price is called elasticity.

Answer:

Step-by-step explanation:

The triangle ABJ is equitorial

So area

Then mBJ is a arc which is 1/6th of circle

Area.

So area of unshaded region

Answer:

\(\textsf{d.} \quad r^2\left(\dfrac{\pi}{6}- \dfrac{\sqrt{3}}{4}\right)\)

Step-by-step explanation:

To find the area of the unshaded region, subtract the area of ΔJGB from the area of sector JGB.

The measure of an arc is equal to its corresponding central angle measure.  Therefore, the central angle of sector JGB is 60°.

As the two sides of ΔJGB adjacent the central angle are the radii of the circle (and therefore equal in length), ∠GJB = ∠GBJ.  

Interior angles of a triangle sum to 180°.  Therefore, all interior angles of ΔJGB are 60° which makes it an equilateral triangle.

Area of an equilateral triangle:

\(\sf A=\dfrac{\sqrt{3}}{4}a^2 \quad \textsf{(where a is the side length)}\)

As the side length of the given equilateral triangle is the radius (r):

\(\implies \sf Area\:of\:triangle=\dfrac{\sqrt{3}}{4}r^2\)

To find the area of the sector, first convert degrees to radians by multiplying the degrees by π/180 :

\(\implies 60^{\circ}=60 \times \dfrac{ \pi}{180}=\dfrac{\pi}{3}\:\:\sf radians\)

Area of a sector of a circle

\(\textsf{A}=\dfrac12 r^2 \theta \quad \textsf{(where r is the radius and the angle }\theta \textsf{ is in radians)}\)

Substituting the angle in radians, the area of the sector is:

\(\implies \sf A=\dfrac{1}{2}r^2\left(\dfrac{\pi}{3}\right)\)

\(\implies \sf A=\dfrac{\pi}6}r^2\)

Area of the unshaded region:

\(\begin{aligned}\textsf{Area of unshaded region} & =\textsf{Area of sector} - \textsf{Area of triangle}\\\\& = \dfrac{\pi}{6}r^2 - \dfrac{\sqrt{3}}{4}r^2\\\\& = r^2\left(\dfrac{\pi}{6}- \dfrac{\sqrt{3}}{4}\right)\end{aligned}\)

Therefore, the solution is option D.

1. R₁ is reflexive. : False2. R is symmetric. : True3. R₁ is transitive. : True

Explanation:Let’s find the solutions one by one below :

1. R₁, is reflexive. : False

Reflexive relation is a relation that maps each element to itself. i.e, if x ∈ A, then x R x. If (i, j) ∈ R₁, then i and j both leave the same remainder on dividing by n.i.e, i = k₁n + r and j = k₂n + r where k₁, k₂ are any integers and r is the remainder then (i, j) ∈ R₁Then, i and i leave the same remainder on dividing by n, therefore (i, i) ∈ R₁.

So, R₁ is reflexive relation. Hence, the given statement is false.

2. R is symmetric. : True

Symmetric relation is a relation such that if (a, b) is in R, then (b, a) is in R. If (i, j) ∈ R, then i and j both leave the same remainder on dividing by n.i.e, i = k₁n + r and j = k₂n + r where k₁, k₂ are any integers and r is the remainder then (j, i) ∈ R.Thus, R is a symmetric relation.

Hence, the given statement is true.

3. R₁, is transitive. : True

Transitive relation is a relation such that if (a, b) and (b, c) are in R, then (a, c) is in R. Let (i, j), (j, k) ∈ R₁, theni = k₁n + r₁ and j = k₂n + r₁j = k₃n + r₂ and k = k₄n + r₂ (r₁ = r₂)where k₁, k₂, k₃, k₄ are any integers and r₁, r₂ are the remainders.Then, i = k₁n + r₁, j = k₂n + r₁ and k = k₄n + r₂i.e, i = k₁n + r₁, k = k₄n + r₂so, i and k leave the same remainder on dividing by n, therefore (i, k) ∈ R₁.

Hence, R₁ is a transitive relation. Therefore, the given statement is true.

The correct answer is option 2. Yes, the mean of the sample proportions is 0.6, which is the same as the population proportion.

To determine if the sample proportion is an unbiased estimator, we need to check if the mean of the sample proportions equals the population proportion. In this case, the population proportion of officers who are younger than 18 is given as 0.6. The sample proportions for all possible samples of size 2 are calculated and given in the table.
To calculate the mean of the sample proportions, we add up all the proportions in the table and divide by the total number of samples, which is 9.
Mean of sample proportions = (0 + 0.5 + 0.5 + 0.5 + 0.5 + 0.5 + 1 + 1 + 1) / 9 = 0.6
Since the mean of the sample proportions equals the population proportion, we can say that the sample proportion is an unbiased estimator.

Step-by-step explanation:

12 inches in one foot, 12 x 5 = 60, meaning it would be 68 inches high

The correct answer is: D. The graph of g(x) is the graph of f(x) shifted to the right 6 units.

In the given function g(x) = f(z - 6), the input variable "z" is being shifted to the right by 6 units. This means that any x-value in the original function f(x) will be replaced with (x - 6) in the function g(x).

Since f(x) is a constant function with a value of 10%, the graph of f(x) is a horizontal line at y = 10%. When we shift the input variable "x" to the right by 6 units in g(x), the horizontal line representing the function f(x) will also shift to the right by the same amount.

Therefore, the correct statement is that the graph of g(x) is the graph of f(x) shifted to the right 6 units.
