1. The average time it takes a customer from when they arrive at the truck until they receive their taco is 141.67 seconds.

2. The average utilization of the truck 141.67 seconds.

3. On average, there is 1 person waiting in line.

4. In order to achieve a delay probability of under 10%, a minimum of 1 server is required.

1 The arrival rate is 1 customer every 2 minutes, which is equivalent to 0.5 customers per minute. The service rate is 1 customer per 50 seconds, which is equivalent to 1.2 customers per minute (since there are 60 seconds in a minute).

2 Average Number of Customers = (0.5 / 1.2) + 1 = 1.4167.

Average Waiting Time = 1.4167 * (50 + 50)

= 141.67 seconds.

3 The average utilization of the truck is given by the formula: Utilization = Arrival Rate / Service Rate.

Utilization = 0.5 / 1.2

= 0.4167 (or 41.67%).

The average number of people waiting in line can be calculated using the formula: Average Number of Customers - Average Utilization.

Average Number of Customers - Average Utilization = 1.4167 - 0.4167

= 1.

4 Given that the desired delay probability is 10% (or 0.1), we can rearrange the formula to solve for the utilization:

Utilization = Delay Probability / (1 + Delay Probability).

=

Utilization = 0.1 / (1 + 0.1) = 0.0909 (or 9.09%).

The utilization we calculated represents the maximum utilization to achieve a delay probability of 10%. In conclusion, to achieve a delay probability of under 10%, a minimum of 1 server is required.

In computer science and mathematics, a graph is a collection of vertices (also known as nodes or points) connected by edges (also known as links or lines).

Based on the given Graph, we can say that the graph represents a position-time graph of a weight attached to a spring.

The initial position of the weight is 40cm as given in tha graph,

We can determine the time at which the weight first reaches equilibrium.

Equilibrium occurs when the weight is at rest and has zero velocity.

This corresponds to the position of the weight being zero, i.e., p(t) = 1/2 cm. The problem states that we say the weight is at equilibrium when p(t) = 1/2 cm.

Therefore, the weight first reaches equilibrium at the time t when p(t) = 1/2 cm.

Complete question:

The weight is initially positioned at a certain distance in centimeters, which is not stated in the query. To ascertain this number, we would need to examine the graph or receive additional information.

Based on the information given, we can say the following:

The graph of the function is a function, which means that each input (time value) corresponds to exactly one output (position value).

The initial position of the weight is some number of centimeters, which is not specified in the question. We would need to look at the graph or be given more information to determine this value.

The weight first reaches equilibrium when the position is 0 cm, which means that the function value is 0. We can find the time(s) when this occurs by solving the equation p(t) = 0.

For example, if the equation is  \(p(t) = 3sin(2t) - 2, we can set 3sin(2t) - 2 = 0\)   and solve for   \(t: 3sin(2t) = 2, sin(2t) = 2/3, 2t = sin^-1(2/3) + 2πn or π - sin^-1(2/3) + 2πn\) for some integer  \(n, t = (sin^-1(2/3) + 2πn)/2 or (π - sin^-1(2/3) + 2πn)/2\)  For some integer n.

The initial position of the weight is its position when t = 0 s, which means we need to look at the value of p(0). Again, this value is not given in the question.

Answer: Concave down

Explanation:

An example is shown below. We have the concave down parabola \(y = -x^2+7\) marked in red. The trapezoidal sum is in blue. The three trapezoids combine to something just a bit smaller than the true area under the curve from x = -2 to x = 1. Therefore, this trapezoidal sum is an underestimate of the true area under the curve.

Every part of each trapezoid is completely below the red curve. In other words, no part of the blue pieces spill above the parabola.

Answer:

v=20π ft/s

Step-by-step explanation:

Given:

Distance from the security car to the movie theater, D=25 ft

Distance of the reflection from the car, d=30 ft

Speed of rotation of the strobe lights, 2 rev/s

To find the speed at which the reflection of the security strobe lights is moving along the wall of the movie theater, we need to calculate the linear velocity of the reflection when it is 30 ft from the car.

We can start by finding the angular velocity in radians per second. Since the strobe lights rotate at 2 revolutions per second, we can convert this to radians per second.

ω=2πf

=> ω=2π(2)

=> ω=4π rad/s

The distance between the security car and the reflection on the wall of the theater is...

r=30-25= 5 ft

The speed of reflection is given as (this is the linear velocity)...

v=ωr

Plug our know values into the equation.

v=ωr

=> v=(4π)(5)

∴ v=20π ft/s

Thus, the problem is solved.

The speed of the reflection of the security strobe lights along the wall of the movie theater is 2π ft/s.

To solve this problem, we can use the concept of related rates. Let's consider the following variables:

x: Distance between the security car and the movie theater wall

y: Distance between the reflection of the security strobe lights and the security car

θ: Angle between the line connecting the security car and the movie theater wall and the line connecting the security car and the reflection of the strobe lights

We are given:

x = 25 ft (constant)

y = 30 ft (changing)

θ = 2 revolutions per second (constant)

We need to find the speed at which the reflection of the security strobe lights is moving along the wall (dy/dt) when the reflection is 30 ft from the car.

Since we have a right triangle formed by the security car, the movie theater wall, and the reflection of the strobe lights, we can use the Pythagorean theorem:

x^2 + y^2 = z^2

Differentiating both sides of the equation with respect to time (t), we get:

2x(dx/dt) + 2y(dy/dt) = 2z(dz/dt)

Since x is constant, dx/dt = 0. Also, dz/dt is the rate at which the angle θ is changing, which is given as 2 revolutions per second.

Plugging in the known values, we have:

2(25)(0) + 2(30)(dy/dt) = 2(30)(2π)

Simplifying the equation, we find:

60(dy/dt) = 120π

Dividing both sides by 60, we get:

dy/dt = 2π ft/s

Explanation:-

To determine the plausible interval containing the middle 95% of the data,  to calculate the margin of error based on the mean and standard deviation obtained from the simulation.

Given that the mean is 0.254 and the standard deviation is 0.060, we can use these values to calculate the margin of error.

The margin of error is typically determined by multiplying the standard deviation by the appropriate critical value for the desired level of confidence. In this case, since  the middle 95% of the data, use a confidence level of 95%.

The critical value associated with a 95% confidence level for a two-tailed test is approximately 1.96.

The margin of error is then calculated as:

Margin of Error = Critical Value * Standard Deviation

= 1.96 * 0.060

= 0.1176

To find the plausible interval, and subtract the margin of error from the mean:

The statement is false. When an economy shrinks at a constant annual rate, the cumulative decline over multiple years is not simply the sum of the annual rates of decline.

To calculate the cumulative decline over the four-year period, we need to use the concept of compound growth/decline.

If the economy shrinks at a rate of 10% per year for four consecutive years, the actual cumulative decline can be calculated as follows:

Cumulative decline = (1 - Rate of decline) ^ Number of years

In this case, the rate of decline is 10% or 0.1, and the number of years is 4.

Cumulative decline = (1 - 0.1) ^ 4

Cumulative decline = 0.9 ^ 4

Cumulative decline = 0.6561

So, the economy would actually shrink by approximately 65.61% over the four-year period, not 40%.

Step-by-step explanation: you just divide them up

The speed of a bird with respect to the wind Bird's air speed is 2.25 mi/h. The speed of the wind with respect to the ground wind's speed is 0.75 mi/h.

Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.

Relative speed is usually given in terms of the speed of body A with respect to another body B (Vab)

Vab = Va - Vb

Vab = Speed of A relative to B

Va = Speed of A

Vb = Speed of B

So, for this question, when the bird is travelling in the same direction of the wind, the speed of the bird with respect to the ground is 3 mi/h

(Speed of bird with respect to the wind)

= (Speed of bird with respect to ground) - (Speed of wind with respect to the ground)

Speed of bird with respect to the wind = x

Speed of bird with respect to ground = 3 mi/h

Speed of the wind with respect to the ground = y

(Speed of bird with respect to the wind)

= (Speed of bird with respect to ground) - (Speed of wind with respect to the ground)

x = 3 - y

When the bird is travelling in the opposite direction, the speed of the bird with respect to the ground is 1.5 mi/h

Speed of bird with respect to the wind = x

Speed of bird with respect to ground = 1.5 mi/h

Speed of the wind with respect to the ground = -y (Negative since the wind is in the opposite direction)

(Speed of bird with respect to the wind)

= (Speed of bird with respect to ground) - (Speed of wind with respect to the ground)

x = 1.5 - (-y)

x = 1.5 + y

We can then solve this system of equations

x = 3 - y

x = 1.5 + y

1.5 + y = 3 - y

y + y = 3 - 1.5

2y = 1.5

Divide both sides by 2

(2y/2) = (1.5/2)

y = 0.75 mi/h

x = 1.5 + y

x = 1.5 + 0.75

x = 2.25 mi/h
