A cart is pulled a distance d on a horizontal surface while it is acted on by five forces, as shown in the diagram. Normal forces of magnitudes n1 and n2 are directed upwards at the rear and front wheels, respectively. Rolling frictional forces of magnitudes f1 and f2 are opposite in direction to the displacement and act on the rear and front wheels, respectively. The weight of the cart, with magnitude w, is directed downward. Finally, a pulling force of magnitude p makes and angle of φ with horizontal. The direction of the displacement is to the right in the diagram.
The work done by the pulling force is [tex]P\cdot d \cdot \cos \theta[/tex].
The work done by rear wheels normal force is 0.

How to determine the work done by a force
In this question, we see a system with six uniform and stable forces. The equation of work done by a uniform and stable force is:
[tex]W = F\cdot s\cdot \cos \theta[/tex] (1)
Where:
[tex]F[/tex] - Force, in newtons. [tex]s[/tex] - Traveled distance, in meters.[tex]\theta[/tex] - Angle of force respect to displacement direction, in degrees.Now we proceed to calculate the work done by each force:
Pulling force ([tex]P[/tex])[tex]W_{P} = P\cdot d\cdot \cos \theta[/tex] (2)
The work done by the pulling force is [tex]P\cdot d \cdot \cos \theta[/tex]. [tex]\blacksquare[/tex]
Rear wheels normal force ([tex]N_{1}[/tex])
[tex]W_{N_{1}} = N_{1}\cdot d\cdot \cos 90^{\circ}[/tex]
[tex]W_{N_{1}} = 0[/tex] (3)
The work done by rear wheels normal force is 0. [tex]\blacksquare[/tex]
Front wheels normal force ([tex]N_{2}[/tex])
[tex]W_{N_{2}} = N_{2}\cdot d\cdot \cos 90^{\circ}[/tex]
[tex]W_{N_{2}} = 0[/tex] (4)
The work done by front wheels normal force is 0. [tex]\blacksquare[/tex]
Rear wheels friction force ([tex]f_{1}[/tex])
[tex]W_{f_{1}} = f_{1}\cdot d\cdot \cos 180^{\circ}[/tex]
[tex]W_{f_{1}} = - f_{1}\cdot d[/tex] (5)
The work done by rear wheels friction force is [tex]-f_{1}\cdot d[/tex]. [tex]\blacksquare[/tex]
Front wheels friction force ([tex]f_{2}[/tex])
[tex]W_{f_{2}} = f_{2}\cdot d\cdot \cos 180^{\circ}[/tex]
[tex]W_{f_{2}} = -f_{2}\cdot d[/tex] (6)
The work done by front wheels friction force is [tex]-f_{2}\cdot d[/tex]. [tex]\blacksquare[/tex]
Weight ([tex]W[/tex])
[tex]W_{W} = W\cdot d\cdot \cos 270^{\circ}[/tex]

Consider the situation in which the health inspector finds the sample mean of the 4 pools to be outside the safe ph levels. As a result, the inspector declares that the population mean is not 7. 5. However, if the population mean really is 7. 5, the inspector will have made an error. Such an error is called a type i error. Find the probability that the inspector will make a type i error with the sample of 4 pools. Show your work.
The probability of Type I error is the likelihood of finding a mean outside
the safe zone for the 4 pools.
The probability that the inspector will make a Type I error is 0.0026What is a Type I error and what is the probability that it will occur?In hypothesis testing, a Type I error is the error of rejecting a true null
hypothesis.
From a similar question, the possible parameters are;
The safe pH levels for swimming pools is between 7.2 and 7.8
The standard deviation is 0.2
The probability that the pH is within the safe zone is found as follows;
[tex]The \ z-score, \ Z = \mathbf{\dfrac{\overline x - \mu}{\dfrac{\sigma}{n} }}[/tex]
Which gives;
[tex]\mathbf{P \left(\dfrac{7.2 - 7.5}{\dfrac{0.2}{\sqrt{4} } } < \dfrac{\overline x - \mu}{\sigma} < \dfrac{7.8 - 7.5}{\dfrac{0.2}{\sqrt{4} }} \right)} = P(-3 < Z < 3)[/tex]
P(-3 < Z < 3) = P(Z < 3) - P(Z > -3) = P(Z < 3) - (1 - P(Z < 3))
P(Z < 3) - (1 - P(Z < 3) = 2·P(Z < 3) - 1
2·P(Z < 3) - 1 = 2 × 0.9987 - 1 = 0.9974
The probability that the swimming pool is not safe = 1 - (2·P(Z < 3) - 1)
1 - (2·P(Z < 3) - 1) = 1 - 0.9974 = 0.0026
Which gives;
The probability that the mean will be seen as not in the safe zone and therefore not 7.5 is 0.0026 and the probability that the inspector will make a Type I error is 0.0026Learn more about hypothesis testing here:

In a multiple choice exam, there are 5 questions and 4 choices for each question (a, b, c, d). Nancy has not studied for the exam at all and decides to randomly guess the answers. What is the probability that:.
Using the binomial distribution, it is found that there is a 0.6836 = 68.36% probability that she guesses at least one right.
For each question, there are only two possible outcomes, either she gets it right or she does not get it right. The probability of getting a question right is independent of any other question, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
There are 5 questions, hence n = 5.For each question, she guesses one out of 4 options, hence p = 1/4 = 0.25.The probability that she guesses at least one right is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{4,0}.(0.25)^{0}.(0.75)^{4} = 0.3164[/tex]
Hence:
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.3164 = 0.6836[/tex]
0.6836 = 68.36% probability that she guesses at least one right.

You leave on a 546-mi trip in order to attend a meeting that will start 10. 8 h after you begin your trip. Along the way you plan to stop for dinner. If the fastest you can safely drive is 65 mi/h, what is the longest time you can spend over dinner and still arrive just in time for the meeting?.
Answer:
Explanation:
To find the time the driver can stop for, we must calculate the time it takes him to complete the trip without any stops:
Time without stops = [tex]\frac{546 miles}{65miles/hour} = 8.32 hours[/tex] (approximated)
Since the driver has 10.8 hours to complete the journey, thus the driver can stop for 10.8hrs - 8.32hrs = 2.48hrs

Which of the following equation has x = 6 as the solution?.
Light stimuli entering the eye encounter a series of structures while traveling to the brain. Place the structures in the correct order.
Placing the structures encountered by light stimuli when entering the eye in correct order is as follows :
Cornea --> Retina ---> Rods and cones ----> Ganglion cells ---> Optic nerve ----> Thalamus ----> Primary visual cortex
Steps followed by the light stimuli
When light enters the eye it will have to travel through these structures before the light stimuli will get to the optic nerve which relates the stimuli to the brain for interpretation and relay of message to the eye.
The cornea is part of the outermost part of the human eye that receives the stimuli before relating it to the retina which in turn sends the stimuli to the rods and cones and so on.
Hence we can conclude that the correct order is as follows : Cornea --> Retina ---> Rods and cones ----> Ganglion cells ---> Optic nerve ----> Thalamus ----> Primary visual cortex.

A company sells kites. It sells basic kites and designer kite's. 2 basic kites and 2 designer kites have a total weight of 400 g. 4 basic kites and 1 designer kite have a total weight of 440 g. Work out the weight of a basic kite and the weight of a designer kite.
Answer:
basic = 80g
designer = 120g
Explanation:
simultaneous equations:
2B + 2D = 400g
4B + D = 440g -> D = 440 - 4B
to work out B:
2B + 2(440 - 4B) = 440
2B + 880 - 8B = 440 # divide whole thing by 2 to make it simpler
B + 440 - 4B = 220
-3B = -240 # divide both sides by -1
3B = 240
B = 80
to work out D: (substitute B)
4(80) + D = 440g
320 + D = 440g
D = 120
As per the given data, a basic kite weighs 80 g and a designer kite weighs 120 g.
What is marketing?Marketing is the activity, set of institutions, and processes for creating, communicating, delivering, and exchanging value-added offerings for customers, clients, partners, and society as a whole.
Let's denote the weight of a basic kite as w_b and the weight of a designer kite as w_d.
We can set up a system of equations based on the given information:
2w_b + 2w_d = 400 (equation 1)
4w_b + 1w_d = 440 (equation 2)
We can then solve for w_b and w_d using elimination or substitution.
Using elimination:
Multiply equation 1 by 2: 4w_b + 4w_d = 800Subtract equation 2 from the above: (4w_b + 4w_d) - (4w_b + 1w_d) = 800 - 440Simplify: 3w_d = 360Solve for w_d: w_d = 120Substitute w_d into equation 1 and solve for w_b: w_b = 80Therefore, a basic kite weighs 80 g and a designer kite weighs 120 g.
