According to New Jersey Transit, the 8:00 a.m. weekday train from Princeton to New York City has a 90% chance of arriving on tim

e. To test this claim, an auditor chooses 6 weekdays at random during a month to ride this train. The train arrives late on 2 of those days. Design and carry out a simulation to estimate the probability that a train with a 90% chance of arriving on time each day would be late on 2 of 6 days.- I am confused on how to do this it’s for a major grade with another problem using the R software.

We evaluate the probability like this:
0.9^4\times0.1^2
the above value is a theoretical estimation, you have 
to get the above value in your simulation, which equate:
0,006561

A gate is made up of a rectangle and a semicircle, as shown. Find the area of the gate. Use 3.14 for .Round your answer to the n
allochka39001 [22]

Answer:

<em>797.0ft²</em>

Step-by-step explanation:

<u>Find a related diagram attached</u>

Area of the gate = Area of the semicircle + Area of the Rectangle

Area of the semicircle = πr²/2

r is the radius

From the diagram, radius r = 20/2 = 10ft

Area of the semicircle = 3.14(10)²/2

Area of the semicircle = 3.14(100)/2

Area of the semicircle = 314/2

Area of the semicircle = 157ft²

Area of the rectangle = Length * Width

Area of the rectangle = 20*32

Area of the rectangle = 640ft²

Area of the gate = 157 + 640

Area of the gate = 797ft²

<em>Hence the area of the gate is 797.0ft²</em>

What model describes the relationship between the amount of money in an account and time, given that the money doubles every mon
quester [9]
If we have a common ratio every set amount of time (and not a common difference or addition), this is an exponential relationship. An exponential equation would have a form like Money = (1000)(2)^(# of months), where every additional month would cause the money amount to double.

A window shaped like a parallelogram has an area of 23 4/5 square feet. The height of the window is 2 4/5 feet. How long is the
USPshnik [31]

Answer:

base = 8\frac{1}{2}ft

Step-by-step explanation:

The general formula for the area of a parallelogram is:

A = bh, where b = the length of the base and h = the height

Using the given values for area and height, we can solve for the missing variable of 'b':

23\frac{4}{5}=\frac{119}{5}

2\frac{4}{5}=\frac{14}{5}

\frac{119}{5}=\frac{14}{5}h

Multiply both sides by the reciprocal:

(\frac{5}{14})(\frac{119}{5})=(\frac{14}{5})(\frac{5}{14})h

\frac{119}{14}=h

h=8\frac{1}{2}ft
