The correct order of the radius  \(\sqrt{3} /11 \ , \pi /24 , 3/25 , 9/100\) .

What is decreasing and increasing order?

A set of data is said to be in descending order, often referred to as decreasing order, when it is arranged from highest to lowest or largest to smallest.

The same concepts apply regardless of the type of information you're working with, whether it's letters, dates, sizes of things or any other group of information like numbers or dates.

For instance, arranging a group of numbers in descending order means doing so from biggest to smallest value.

Ascending order, often known as ascending order of importance, is the exact opposite of declining order.

The order of the items is lowest to highest value. The lowest value is placed first in the order, while the highest value is placed last.

The value of \(\sqrt{3}\) = 1.732

so \(\sqrt{3}\) / 11 = 1.732/11

=1732/11000

The value of \(pi\) = 3.14

so \(\pi\) / 24  = 3.14/24

= 314/2400

The number of subscribers with land-line phones for any year after 2000, taking into account the 27% annual decline rate.

According to the given information, land-line phones are decreasing at a rate of 27% each year since 2000. This means that each year, the number of subscribers with land-line phones is reduced to 73% (100% - 27%) of the previous year's value.

To create a formula that models this scenario, we start with the initial number of subscribers in the year 2000, which is given as 10,000. We can express this as y(0) = 10,000, where y(0) represents the number of subscribers in the starting year (t = 0).

Based on the decline rate of 27% per year, we can express the relationship between the number of subscribers in a given year (y) and the number of subscribers in the previous year (y-1) as follows:

y = 0.73 * y(t-1)

Here, 0.73 represents the probability of retaining a land-line phone subscription from one year to the next, given the 27% annual decline rate. Multiplying this probability by the number of subscribers in the previous year gives us the estimated number of subscribers in the current year.

By iterating this formula year after year, we can estimate the number of subscribers with land-line phones for any given year after 2000.

For example, let's calculate the number of subscribers in the year 2023, which is 23 years after 2000 (t = 23). Using the formula, we can substitute t = 23 into the equation:

y(23) = 0.73 * y(22)

To find y(22), we substitute t = 22 into the equation:

y(22) = 0.73 * y(21)

We continue this process until we reach the starting year, y(0) = 10,000.

Answer:

Step-by-step explanation:

no graph was shown

The range of T is spanned by {a - 3b, at² - 3b, at⁴ - 3b}. To simplify this basis, we can choose b = 0

We are given a linear transformation T : P₂ -> P₅ defined by T(p(t)) = at² - 3b, where p(t) = at + bt + c for arbitrary constants a, b, and c.

To determine whether r(t) = 2t² - 6 is in the range of T, we need to find a polynomial p(t) in P₂ such that T(p(t)) = r(t).

Let p(t) = (2a/3)t² - 2bt + (2b/3) - (2c/3). Then we have:

T(p(t)) = a((2a/3)t² - 2bt + (2b/3) - (2c/3))² - 3b

= (4/9)a²t⁴ - (8/3)abt³ + (4/3)abt² + (4/9)a²bt² - (4/3)abt + (4/9)b² - 2ac/3 + 2b²/9 - 3b

Simplifying this expression, we get:

T(p(t)) = (4/9)a²t⁴ - (8/3)abt³ + (4/3)a²bt² + (4/9)b² - (4/3)abt - 2ac/3 + 2b²/9 - 3b

Comparing this with r(t) = 2t² - 6, we see that we need to solve the following system of equations:

(4/9)a² = 2

-(8/3)ab = 0

(4/3)a²b = 0

(4/9)b² = -6

-(4/3)ab = 0

-2ac/3 + 2b²/9 - 3b = 0

From the second equation, we get either a = 0 or b = 0. If a = 0, then the first and third equations give b = 0 as well, which implies that the fourth and fifth equations are not satisfied. Therefore, we must have b = 0. Then the first equation gives a = ±√(9/2).

If a = √(9/2), then the third equation is not satisfied. If a = -√(9/2), then the third equation gives b = 0, and the fourth equation gives c = ±√(27/2). Therefore, we have:

T(p(t)) = -(9/2)t² ± 9

Since r(t) = 2t² - 6 is not of this form, it is not in the range of T.

To find a basis for the range of T, we need to find the span of the set of polynomials {T(1), T(t), T(t²)}. We have:

T(1) = a - 3b

T(t) = at² - 3b

T(t²) = a(t²)² - 3b = a(t⁴) - 3b

Therefore, the range of T is spanned by {a - 3b, at² - 3b, at⁴ - 3b}. To simplify this basis, we can choose b = 0 (since the value of b does not affect the range of T), and then we have:

{a, at², at⁴}

This is a basis for the range of T.

To find a polynomial in the kernel of T, we need to solve the equation

The size of the quarterly deposits in Shelby's RRSP account was approximately $147.40.

Let's denote the size of the quarterly deposits as \(D\). The total number of deposits made over 9 years is \(9 \times 4 = 36\) since there are 4 quarters in a year. The interest rate per period is \(r = \frac{3.50}{100 \times 12} = 0.0029167\) (3.50% annual rate compounded monthly).

Using the formula for the future value of an ordinary annuity, we can calculate the accumulated value of the RRSP fund:

\[55,000 = D \times \left(\frac{{(1 + r)^{36} - 1}}{r}\right)\]

Simplifying the equation and solving for \(D\), we find:

\[D = \frac{55,000 \times r}{(1 + r)^{36} - 1}\]

Substituting the values into the formula, we get:

\[D = \frac{55,000 \times 0.0029167}{(1 + 0.0029167)^{36} - 1} \approx 147.40\]

Therefore, the size of the quarterly deposits, rounded to the nearest cent, is approximately $147.40.

The expected value of buying one ticket in this charity raffle is $0.42. This means that, on average, a person can expect to win approximately $0.42 if they purchase a single ticket.

To calculate the expected value, we need to consider the probability of winning each prize multiplied by the value of the prize. Let's break it down:

- There is a 1/5000 chance of winning the $600 prize, so the expected value contribution from this prize is (1/5000) * $600 = $0.12.

- There are 3/5000 chances of winning the $300 prize, so the expected value contribution from these prizes is (3/5000) * $300 = $0.18.

- There are 5/5000 chances of winning the $40 prize, so the expected value contribution from these prizes is (5/5000) * $40 = $0.04.

- Finally, there are 20/5000 chances of winning the $5 prize, so the expected value contribution from these prizes is (20/5000) * $5 = $0.08.

Summing up all the expected value contributions, we get $0.12 + $0.18 + $0.04 + $0.08 = $0.42.

Answer:

We conclude that (4, 2) is NOT a solution to the system of equations.

Step-by-step explanation:

Given the system of equations

\(y = x - 2\)

\(y = 3x + 4\)

Important Tip:

Let us solve the system of equations using the elimination method.

\(\begin{bmatrix}y=x-2\\ y=3x+4\end{bmatrix}\)

Arrange equation variables for elimination

\(\begin{bmatrix}y-x=-2\\ y-3x=4\end{bmatrix}\)

Subtract the equations

\(y-3x=4\)

\(-\)

\(\underline{y-x=-2}\)

\(-2x=6\)

Now, solve -2x = 6 for x

\(-2x=6\)

Divide both sides by -2

\(\frac{-2x}{-2}=\frac{6}{-2}\)

Simplify

\(x=-3\)

For y - x = -2 plug in x = -3

\(y-\left(-3\right)=-2\)

\(y+3=-2\)

Subtract 3 from both sides

\(y+3-3=-2-3\)

Simplify

\(y=-5\)

The solution to the system of equations is:

(x, y) = (-3, -5)

Checking the graph

From the graph, it is also clear that (4, 2) is NOT a solution to the system of equations because (-3, -5) is the only solution as we have found earlier.

Therefore, we conclude that (4, 2) is NOT a solution to the system of equations.

What is a linear equation in two variables?

If an equation is written in the form ax + by + c=0, where a, b, and c are real numbers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables.

Given: Linear equation y = 3x + 5

We know that,

The linear equation in two variables in the form of ax + by + c = 0

For x = 0, y = 0 + 5 = 5. Therefore, (0, 5) is one solution.

For x = 1, y = 3 × 1 + 5 = 8. Therefore, (1, 8) is another solution.

For y = 0, 3x + 5 = 0, x = -5/3. Therefore, (-5/3, 0) is another solution.

Clearly, for different values of x, we get various values for y. Thus, any value substituted for x in the given equation will constitute another solution for the given equation. So, there is no end to the number of different solutions obtained by substituting real values for x in the given linear equation. Therefore, a linear equation in two variables has infinitely many solutions.

Hence, the given equation y = 3x + 5 has infinitely many solutions.

The parent linear function is:

If first we apply a vertical dilation of scale factor 4 to the parent linear function, we will get:

The probability that the mean salary of the 100 players exceeded $3.4 million is 0.121

We can use the central limit theorem to approximate the probability of the mean salary of the 100 players exceeding $3.4 million. According to the central limit theorem, the sample mean of a sufficiently large sample size (n>30) will be normally distributed regardless of the underlying distribution of the population.

The mean of the sample means is equal to the population mean, which is $3.26 million. The standard deviation of the sample means, also known as the standard error of the mean, is calculated by dividing the population standard deviation by the square root of the sample size

standard error of the mean = population standard deviation / √(sample size)

standard error of the mean = $1.2 million / √(100)

standard error of the mean = $0.12 million

To find the probability that the mean salary of the 100 players exceeded $3.4 million, we need to standardize the sample mean using the standard error of the mean

z = (sample mean - population mean) / standard error of the mean

z = ($3.4 million - $3.26 million) / $0.12 million

z = 1.17

Using a standard normal distribution table or calculator, we can find that the probability of a z-score of 1.17 or higher is approximately 0.121
