This can be verified by observing that the output signal y(t) does not depend on future input signals x(t + t0) for any value of t0. Therefore, the given system is causal.

The given system is not linear and time-invariant but it is causal. The reasons for this are explained below: The given system is not linear as the output signal is not proportional to the input signal.

Consider two input signals x1(t) and x2(t) and corresponding output signals y1(t) and y2(t). y1(t) = x1(t)sin(we*t) and y2(t) = x2(t)sin(we*t)

Now, if we add these input signals together i.e. x(t) = x1(t) + x2(t), then the output signal will be y(t) = y1(t) + y2(t) which is not equal to x(t)sin(we*t). Therefore, the given system is not linear. The given system is not time-invariant as it does not satisfy the principle of superposition.

Consider an input signal x1(t) with output signal y1(t).

Now, if we shift the input signal by a constant value, i.e. x2(t) = x1(t - t0), then the output signal y2(t) is not equal to y1(t - t0). Therefore, the given system is not time-invariant.

The given system is causal as the output signal depends only on the present and past input signals.

This can be verified by observing that the output signal y(t) does not depend on future input signals x(t + t0) for any value of t0. Therefore, the given system is causal.

(a) This statement is false. The probability of getting heads or tails on a fair coin is always 50%, regardless of previous outcomes.  

(b) This statement is true. Drawing a face card and drawing a red card from a full deck of playing cards are mutually exclusive events.

(a) The statement is false. The outcome of each coin toss is independent of the previous tosses. Therefore, the chance of getting heads on the next toss is still 50%, regardless of the outcome of the previous eight tosses.

(b) The events of drawing a face card and drawing a red card are not mutually exclusive events. There are 12 face cards in a deck of playing cards, and 6 of them are red (2 jacks, 2 queens, and 2 kings). Therefore, the probability of drawing a face card and a red card from a full deck of playing cards is:

P(face card and red card) = P(face card) x P(red card|face card)
P(face card and red card) = (12/52) x (6/12)

The area of the rectangular parking lot is 929.03 square meters.

Use the formula for the area of a rectangle to calculate the area of the rectangular parking lot, which is given as:

Area = length × width

We know that the parking lot is 67.5 ft wide and 148 ft long, the area can be calculated as follows:

Area = 67.5 ft × 148 f

t= 9990 sq. ft

However, the question asks for the area in square meters, so we need to convert square feet to square meters. 1 square foot is equal to 0.092903 square meters, so we can use this conversion factor to convert square feet to square meters.

Area in square meters = Area in square feet × 0.092903

= 9990 sq. ft × 0.092903

= 929.03 sq meters

Therefore, the area is 929.03 square meters.

The point of intersection, P, between the given line and the plane is represented by the ordered triple (145/59, 301/59, 561/59).

To find the point of intersection, P, between the given line and the plane, we need to substitute the equations of the line into the equation of the plane and solve for the parameter, t.

The line is defined by the following parametric equations:

x = 2 + 9t

y = 5 + 2t

z = 9 + 10t

The equation of the plane is:

-5x + 8y - 3z = 0

Substituting the equations of the line into the plane equation, we get:

-5(2 + 9t) + 8(5 + 2t) - 3(9 + 10t) = 0

Simplifying this equation, we have:

-10 - 45t + 40 + 16t - 27 - 30t = 0

-45t + 16t - 30t - 10 + 40 - 27 = 0

-59t + 3 = 0

-59t = -3

t = -3 / -59

t = 3 / 59

Now that we have the value of t, we can substitute it back into the parametric equations of the line to find the coordinates of point P.

x = 2 + 9t

x = 2 + 9(3 / 59)

x = 2 + 27 / 59

x = (2 * 59 + 27) / 59

x = (118 + 27) / 59

x = 145 / 59

y = 5 + 2t

y = 5 + 2(3 / 59)

y = 5 + 6 / 59

y = (295 + 6) / 59

y = 301 / 59

z = 9 + 10t

z = 9 + 10(3 / 59)

z = 9 + 30 / 59

z = (531 + 30) / 59

z = 561 / 59

Therefore, the coordinates of point P, where the line intersects the plane, are (145/59, 301/59, 561/59).

The value of the standard deviation of the weekly earnings of the bus drivers is $14.57.

To solve this problem, we can use the standard normal distribution table or a calculator that provides the inverse of the standard normal distribution. Let X be the weekly earnings of the bus drivers, then we have:

P(X > $429.35) = 0.011

Using the standard normal distribution table or calculator, we can find the z-score that corresponds to a probability of 0.011, which is approximately -2.33. We can then use the formula for standardizing a normal variable:

z = (X - μ) / σ

where μ is the mean and σ is the standard deviation of the distribution. Substituting the given values, we have:

-2.33 = ($429.35 - $395) / σ

Solving for σ, we get:

σ = ($429.35 - $395) / (-2.33) = $14.57

Therefore, the value of the standard deviation of the weekly earnings of the bus drivers is $14.57.

the lateral surface area of the triangular prism with measurement of 5cm, 5cm, 4cm, 6cm and 12cm is 140 cm².

To find the lateral surface area of a triangular prism, we need to calculate the sum of the areas of all the rectangular faces of the prism. In this case, the triangular prism has two triangular faces and three rectangular faces. The triangular faces have dimensions of 5 cm (base) and 4 cm (height), while the rectangular faces have dimensions of 5 cm (width), 6 cm (height), and 12 cm (length).

To calculate the area of one of the triangular faces, we use the formula for the area of a triangle:

Area = (1/2) x base x height

In this case, the base is 5 cm and the height is 4 cm, so the area of one triangular face is:

Area = (1/2) x 5 cm x 4 cm = 10 cm²

Since there are two triangular faces, the total area of the triangular faces is: Total area of triangular faces = 2 x 10 cm² = 20 cm²

To calculate the area of one of the rectangular faces, we use the formula for the area of a rectangle: Area = length x width

In this case, the dimensions of the rectangular faces are 6 cm (height) x 5 cm (width) and 12 cm (length) x 5 cm (width), so the areas of these faces are: Area of one rectangular face = 6 cm x 5 cm = 30 cm²

Area of another rectangular face = 12 cm x 5 cm = 60 cm²

Since there are three rectangular faces, the total area of the rectangular faces is: Total area of rectangular faces = 30 cm² + 60 cm² + 30 cm² = 120 cm²

Finally, the lateral surface area of the triangular prism is the sum of the areas of the triangular and rectangular faces:

Lateral surface area = Total area of triangular faces + Total area of rectangular faces

Lateral surface area = 20 cm² + 120 cm² = 140 cm²

Therefore, the lateral surface area of the triangular prism is 140 cm².

A collection of statistical methods that generally requires very few, if any, assumptions about the option (b)  nonparametric methods

Parametric methods in statistics make assumptions about the underlying probability distribution of the population from which the data is drawn. These assumptions may include assumptions about the mean, variance, or other parameters of the population. Examples of parametric methods include t-tests, ANOVA, and linear regression.

Nonparametric methods, on the other hand, are statistical methods that do not require such assumptions about the population distribution. Instead, these methods rely on ranks or other non-numerical data to make inferences about the population. Nonparametric methods are sometimes called distribution-free methods because they make very few or no assumptions about the population distribution.

The following data shows the daily production of cell phones. 7, 10, 12, 15, 18, 19, 20. Mean The formula for finding the mean is: mean = (sum of observations) / (number of observations).

Therefore, the mean for the daily production of cell phones is: Mean = (7+10+12+15+18+19+20) / 7

= 101 / 7

Mean = 14.43

Variance The formula for finding the variance is: Variance = (sum of the squares of the deviations) / (number of observations - 1) Where the deviation of each observation from the mean is: deviation = observation - mean First, calculate the deviation for each observation:7 - 14.43

= -7.4310 - 14.43

= -4.4312 - 14.43

= -2.4315 - 14.43

= 0.5718 - 14.43

= 3.5719 - 14.43

Now, square each of these deviations: 56.25, 19.62, 5.91, 0.33, 12.75, 20.9, 30.96 The sum of these squares of deviations is: 56.25 + 19.62 + 5.91 + 0.33 + 12.75 + 20.9 + 30.96

= 147.72

Therefore, the variance for the daily production of cell phones is: Variance = 147.72 / (7-1) = 24.62 Standard deviation ) Mean = 14.43b) Variance per Day = 24.62c) Standard Deviation = 4.96
