Renuka Jain's Car Wash takes a constant time of 4.5 minutes in its automated car wash cycle. Autos arrive following a
Poisson distribution at the rate of 9 per hour. Renuka wants to know:
a) The average wait time in the line = ______ minutes (round your response to two decimal places).
b) The average number of customers waiting on line = ______ cars (round your response to two decimal places)
a) The average wait time in the line = 13.33 minutes.
b) The average number of customer waiting on line = 4.67 minutes
What do you mean by average?
The average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
a) Values:
Arrival rate = 9 per hour
Service rate [tex]= \frac{60}{Service\ time}[/tex]
Service rate [tex]= \frac{60}{4.5} = 13.33[/tex] minutes
b) Queue:
units in queue(LQ) = Arrival Time^2 / (Service rate* (Service rate - Arrival rate))
unit in queue(LQ) [tex]= \frac{ 9^2}{(13.33\times (13.33 - 9))}[/tex]
unit in queue(LQ) = 0.70
Time in Queue(WQ) = Arrival rate / (Service rate * (Service rate - Arrival rate))
time in queue (WQ) [tex]= \frac{9}{ (13.33 \times (13.33 - 9)}[/tex]
time in queue (WQ) = 4.67 minutes

Find the measure of the marked angles
The measure of the angles is=
The measure of the angles are (4x + 24)° = 52° and (6x - 10)° = 32°; The value of x =7°.
What is vertically opposite angles?
The opposing angles created by the junction of two lines are known as vertical angles or vertically opposite angles. A pair of angles that are vertically opposed to one another are always equal.Vertically opposite angles, or ical angles. A pair of angles that are vertically opposed to one another are always equal. Additionally, a vertical angle and the angle to which it is adjacent are supplementary angles, meaning their sum is 180 degrees.Two lines are said to intersect when they cross at a certain location in a plane. The lines are referred to as parallel when they do not intersect at any point in the plane.So, (4x + 24)° = (6x - 10)°
24° - 10° = 6x - 4x
2x = 14°
x = 14°/2
x = 7°
Substitute x in those values:
(4x + 24) = (4(7) + 24)°
= 28+24
= 52°
(6x - 10)° = (6(7) -10)
= 42° - 10°
= 32°
Hence, the measure of the angles are (4x + 24)° = 52° and (6x - 10)° = 32°; The value of x =7°.

Yadira and her friend are renting a property together. The monthly rent is $1,050.00, and monthly utilities will average $365.00. Yadira will pay three fifths of the rent since her bedroom is larger. Determine how much Yadira's friend will pay each month for rent and utilities. (1 point)
$420.00
$602.50
$707.50
$812.50
Answer:
$602.50
Step-by-step explanation:
The monthly rent is $1,050.00.
If Yadira pays 3/5 ths of the rent, then her friend will pay 2/5 ths of the rent:
[tex]\implies \sf \dfrac{2}{5}\;of\;1050=\dfrac{2}{5} \times 1050=420[/tex]
Therefore, Yadira's friend pays $420 for rent.
If the monthly utilities average is $365, Yadira's friend's portion of the utilities will be half of the total:
[tex]\implies \sf \dfrac{1}{2}\;of\;365=\dfrac{1}{2} \times 365=182.5[/tex]
Therefore, Yadira's friend pays $182.50 for utilities.
So the total amount Yadira's friend will pay each month is:
[tex]\implies \sf Rent + Utilities=420+182.50=602.50[/tex]

One plane can travel 10 miles per hour faster than another. One of them goes 510 miles in the same time it takes the other to go 495 miles. What are their speeds?
The planes' speeds would be ____ miles per hour.
This is a proportion math problem.
If one plane can travel 10 miles per hour faster than another. The planes' speeds would be 435 miles per hour.
How to find the speed?let s = speed of the slower plane
then
(s+10) = speed of the faster
time = distance /speed
495/s =510 /(s+10)
495s = 510s + 5100
Combine like terms
495 - 510s = 5100
15s = 5100
Divide both side by 15s
s = 5100/15
s = 425 mph ( speed of the slower plane)
Speed of the fastest plane
(s+10)
425 +10
= 435 mph
Therefore the speed of the fastest is 435 mph.

A restaurant has 2/5
pounds of butter to divide
equally among 4 butter
dishes. How much is put in
each dish?
===================================================
Explanation:
Check out the diagram below.
I recommend getting graph paper for this problem.
Draw a box that is 5 units tall and 4 units across. There are 5*4 = 20 small squares inside this box. Each small square represents 1/20.
Shade two of the five rows to represent the fraction 2/5. This is the amount of butter we have. The 4 columns shows the butter divided into 4 equal pieces. Note how each column has 2 shaded squares out of 5 squares total. Since each small square represents 1/20, two such squares gets us 2/20 = 1/10 which is the amount of butter per dish.
------------
Another approach would be to say
[tex]\frac{2}{5} \div 4 = \frac{2}{5} \times \frac{1}{4} = \frac{2*1}{5*4} = \frac{2}{20} = \frac{1}{10}[/tex]

To work to pay for the refurbished computer exists 89 hours.
What is meant by tax?Tax compliance refers to policy actions and individual behavior aimed at ensuring that taxpayers are paying the right amount of tax at the right time and securing the correct tax allowances and tax reliefs.
Tax is defined as a mandatory financial charge or some other type of levy imposed on a taxpayer (an individual or legal entity) by a governmental organization in order to fund government spending and various public expenditures (regional, local, or national).
First estimate all the deduction
FICA = $10 per hour × 0.0765 = $0.77 per hr
Fed tax = $10 per hr × 0.12 = $1.2 per hr
State tax = $10 per hr × 0.08 = $0.8 per hr
Remaining pay = 10 – 0.77 – 1.2 – 0.8 = $7.23 per hour
Time required = $640 / $7.23 per hr
Time required = 89 hours

(Type an integer or decimal rounded to the nearest tenth as needed.)
The length, labeled 350-2x in the figure, is
(Type an integer or decimal rounded to the nearest tenth as needed.)
The largest area that can be enclosed is
The solution to the questions are:
The width, labelled x in the figure is 87.5 metersThe length, labelled 350-2 x in the figure, is 175 metersThe largest area that can be enclosed is 15312.5 square metersHow to determine the width and the length of the rectangle?From the question, we have the following parameters that can be used in our computation:
Length = 350 - 2x
Width = x
The area of a rectangle is the product of its dimensions
So, we have
Area = Length x Width
Substitute the known values in the above equation, so, we have the following representation
A = (350 - 2x) * x
Evaluate
A = 350x - 2x²
Differentiate and set to 0
350 - 4x = 0
So, we have
4x = 350
Divide by 4
x = 87.5
Recall that
Length = 350 - 2x
So, we have
Length = 350 - 2 x 87.5
Evaluate
Length = 175
The area is then calculated as
Area = Length x Width
So, we have
Area = 175 x 87.5
Evaluate
Area = 15312.5 square meters
Hence, the area is 15312.5 square meters
