The value of the Mean & Standard deviation is 1.30 and 1.18.

According to the statement

we have a given that the random variable x represents the number of computers that families have along with the corresponding probabilities.

And we have to find the mean and standard deviation from the given data which is related to the probabilities values

So, according to the given data

The formula to compute the mean is:

Mean = summation [x*p(x)]

Compute the mean as follows:

Mean = summation [x*p(x)]

Mean = summation [0*0.49 + 1* 0.05 + 2*0.32 + 3*0.07 + 4*0.07]

Mean = 0 +0.05 + 0.64 + 0.21 + 0.28

Mean = 1.18

The mean of the random variable x is 1.18.

And after calculating the variance from the formula get

The value of standard deviation is 1.30

So, The value of the Mean & Standard deviation is 1.30 and 1.18.

The given statement "The q-system of inventory submits inventory orders at random times" is true because it is based on the q-model's assumption that demand is random and that inventory is replenished when it falls to a certain level.

The q-system of inventory, also known as the q-model or the reorder point system, is a method of inventory control that sets a reorder point (q) at which inventory is replenished.

The system assumes that demand for inventory is random and that inventory is replenished when it falls to the q-level. Since demand is random, orders will be submitted at random times based on the inventory level, and not according to a predetermined schedule.

Therefore, the given statement is true because the q-system of inventory submits inventory orders at random times based on the random demand for inventory.

The probability distribution that would be used in this scenario is the binomial distribution.

The binomial distribution is used to calculate the probability of a certain number of successes in a fixed number of independent trials, given a known probability of success in each trial. In this case, the number of successes is owning stocks, the number of trials is 10 people, and the probability of success is one in four adults owning stocks.

In this case, the probability that exactly three out of ten people own stocks, given that one in four adults own stocks, you would use the binomial probability distribution. The reasoning for this is because the binomial distribution is used when there are a fixed number of trials (in this case, 10 people), each trial has only two possible outcomes (owning stocks or not owning stocks), and the probability of success (owning stocks) is the same for each trial (1 in 4 or 0.25).

The area under the standard normal distribution curve between z = 1 and z = 1.73 is 0.1169 (rounded to three decimal places).

To find the area under the standard normal distribution curve between the z-scores of 1 and 1.73, we need to calculate the cumulative probability or area under the curve.

Using a standard normal distribution table or a calculator, we can find the corresponding probabilities for each z-score.

For z = 1:

The cumulative probability or area to the left of z = 1 is approximately 0.8413.

For z = 1.73:

The cumulative probability or area to the left of z = 1.73 is approximately 0.9582.

To find the area between the two z-scores, we subtract the cumulative probability of the lower z-score from the cumulative probability of the higher z-score.

Area = 0.9582 - 0.8413 = 0.1169

Therefore, the area under the standard normal distribution curve between z = 1 and z = 1.73 is 0.1169 (rounded to three decimal places).

The required matrices are:

\(A= \begin{bmatrix}1 & 1 & 0\\1 & -1 & 0\end{bmatrix}\) and \(B= \begin{bmatrix}1 & 1\\1 & -1\\0 & 1\end{bmatrix}\)

letting T(x)=Ax and U(x)=Bx, the composition T∘U is a reflection over the line y=x.

A matrix is a rectangular array of numbers or other mathematical objects (such as complex numbers, polynomials, or functions) arranged in rows and columns. The size or dimensions of a matrix are given by the number of rows and columns it has, and a matrix with m rows and n columns is said to be an m × n matrix.

Let A be the 2×3 matrix:

\(A= \begin{bmatrix}1 & 1 & 0\\1 & -1 & 0\end{bmatrix}\)

and let B be the 3×2 matrix:

\(B= \begin{bmatrix}1 & 1\\1 & -1\\0 & 1\end{bmatrix}\)

Then, for any vector x in \(R^2\), we have:

\(T(U(x)) = A(Bx) = A(x_1 + x_2, x_1 - x_2, x_3)\)

             \(= (x_1 + x_2 + x_1 - x_2, x_1 - x_2 - x_1 - x_2, 0)\)

             \(= (2x_1, -2x_2, 0)\)

To show that this is a reflection over the line y=x, we can verify that T(U(x)) is equal to its own inverse. That is, we want to show that:

\(T(U(T(U(x)))) = x\)

Substituting T(U(x)) for y, we have:

\(T(U(T(U(x)))) = T(U(y)) = A(By) = A(2y_1, -2y_2, 0)\)

                        \(= (2y_1 + (-2y_2), 2y_1 - (-2y_2), 0)\)

                        \(= (4y_1, 4y_2, 0)\)

To see that this is equal to x, we note that the first and second components have been swapped, which corresponds to a reflection over the line y=x. Thus, T(U) is indeed a reflection over the line y=x.

The radius of the wheel on a car is 30 inches. If the wheel is revolving at 401 revolutions per minute, The linear speed of the car is approximately 19.2 miles per hour.

To find the linear speed of the car in miles per hour, we need to calculate the distance traveled in one minute and then convert it to miles per hour. Here's how we can do it step by step:

Calculate the circumference of the wheel:

The circumference of a circle is given by the formula

C = 2πr

where r is the radius of the wheel.

In this case, the radius is 30 inches, so the circumference is

C = 2π(30)

   = 60π inches.

Calculate the distance traveled in one revolution:

Since the circumference represents the distance traveled in one revolution, the distance traveled in inches per revolution is 60π inches.

Calculate the distance traveled in one minute:

Multiply the distance traveled in one revolution by the number of revolutions per minute.

In this case, it is 60π inches/rev * 401 rev/min = 24060π inches/min.

Convert the distance to miles per hour:

There are 12 inches in a foot, 5280 feet in a mile, and 60 minutes in an hour.

Divide the distance traveled in inches per minute by (12 * 5280) to convert it to miles per hour.

The final calculation is (24060π inches/min) / (12 * 5280) = (401π/66) miles/hour.

Approximating π to 3.14, the linear speed of the car is approximately (401 * 3.14 / 66) miles per hour, which is approximately 19.2 miles per hour.

Convenience sampling is a type of non-probability sampling method where the researcher selects participants based on their accessibility and proximity to the researcher. In this case, the personnel director chose employees from the department nearest her office for the study.

This approach may not provide a fully representative sample of the entire company's employee population, as it doesn't account for possible differences in eating habits across various departments. Therefore, the findings from this study might not accurately represent the proportion of employees who buy lunch in the cafeteria, bring their own lunches, or go out to lunch for the entire company.

Answer:

It will double in the year 2063

Step-by-step explanation:

Let the amount deposited be $x, when it doubles, the amount becomes $2x

we can use the compound interest formula to know when this will happen

The compound interest formula is as follows;

A = P(1+r/n)^nt

In this question,

A is the amount which is 2 times the principal and this is $2x

P is called the principal and it is the amount deposited which is $x

r is the interest rate which is 3.2% = 3.2/100 = 0.032

n is the number of times compounding takes place per year which is quarterly which equals to 4

t is the number of years which we want to calculate.

Substituting all these into the equation, we have;

2x = x(1+0.032/4)^4t

divide through by x

2 = (1+ 0.008)^4t

2 = (1.008)^4t

we use logarithm here

Take log of both sides

log 2 = log (1.008)^2t

log 2 = 2t log 1.008

2t = log 2/log 1.008

2t = 86.98

t = 86.98/2

t =43.49 which is 43 years approximately

Thus the year the money will double will be 2020 + 43 years = 2063

The required volume of the wallet in m3 is 0.001393030684 m3.

Given, The volume of a wallet is 8.50 in. 3.

Convert this value to m3, using the definition 1 in. = 2.54 cm.

The given value of volume is 8.50 in.3.

But we need to convert it into m3.

We have, 1 in. = 2.54 cm.

Hence, 1 in.3 = (2.54 cm)3

                      = (2.54 × 2.54 × 2.54) cm3

                      = 16.387064 cm3

In order to convert the value from cm3 to m3, we need to follow the given steps:1

m = 100 cm

⇒ (1 m)3 = (100 cm)3

               = 106 cm3

Now, we have the relation, 16.387064 cm3 = 1 in.3

⇒ 1 cm3 = (1/16.387064) in.3

∴ 8.50 in.3 = 8.50 × 16.387064 cm3

                  = 139.3030684 cm3

∵ 1 m3 = (1/106) cm3

∴ 139.3030684 cm3= (139.3030684 × 10−6) m3

∴ 8.50 in.3= 1.393030684 × 10−3 m3

                 = 0.001393030684 m3

Hence, the required volume of the wallet in m3 is 0.001393030684 m3.
