Cars enter a car wash at a mean rate of 4 cars per half an hour. What is the probability that, in any hour, exactly 4 cars will enter the car wash? Round your answer to four decimal places.
The probability that, in any hour, exactly 5 cars will enter the car wash is P(x = 5) = 0.0920.
This can be modeled as a Poisson random variable.
The mean rate is the parameter of the Poisson distribution:
λ = 4 cars/30 mins
λ = 8 cars/hr
The probability that exactly k cars will enter the car wash can be calculated as:
P(x = k) = ([tex]8^{k}[/tex] × [tex]e^{-8}[/tex]) ÷ k!
Then, the probability that exactly 5 cars will enter the car wash for k=5 is:
P(5) = ([tex]8^{5}[/tex] × [tex]e^{-8}[/tex]) ÷ 5!
P(5) = (32768 × 0.0003) ÷ 120
P(5) = 0.0920

Keandre wants to buy a new pair of shoes that costs $220. In order to earn money for this, Keandre babysits his neighbor for $10 an hour. He also has saved up his monthly allowance which totals $50. What is the minimum number of hours he should babysit in order to be able to afford the shoes?
Answer:
Step-by-step explanation:
$220=$10x+$50
x= hours
subtract $50 from both sides making sure to cancel the right side
$220-$50=$10x
$170=$10x
Divide both sides by $10 to leaving x by itself on the right side
$170/$10=x
17hrs=x
The minimum number of hours is 17 hours to babysit in order to be able to afford the shoes.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Cost of new pair of shoes = $220
In order to earn money for this, Keandre babysits his neighbor for $10 an hour.
And, He also has saved up his monthly allowance which totals $50.
Now,
Let number of minimum hours = x hour
So, We can formulate;
⇒ $10x + $50 = $220
Solve for x as;
⇒ $10x + $50 = $220
Subtract 50 both side, we get;
⇒ $10x + $50 - $50 = $220 - $50
⇒ $10x = $170
Divide by 10 both side, we get;
⇒x = 17
Thus, The minimum number of hours is 17 hours to babysit in order to be able to afford the shoes.

The Radius is 15.27 cm and the the Diameter is 30.55 cm
Given
Circumference = 96cm
Circumference is the total arc length of a circle or it is simply the perimeter of a circle.
The formula for circumference is 2πr
where π = Ratio of circumference to the diameter of a circle
π = 3.14
r = Radius of the circle
Substituting the value in the formula we get
2πr = 96 cm
πr = 48 cm
r = 15.27 cm
Diameter (d) = 2 × r
hence d = 2 × 15.27 cm

Step-by-step explanation:
Sine is always the side opposite the angle and the hypotenuse
Answer:
[tex]\large \text{Second Choice: $\dfrac{a}{c}$}[/tex]
Step-by-step explanation:
For any given triangle, the Law Of Sines states that the ratio of each side to the sine of the angle opposite that side is the same
So we have
[tex]\dfrac{a}{\sin \angle F} = \dfrac{c}{\sin \angle 90} = \dfrac{b}{\sin \angle G} \\\\[/tex]
[tex]\sin \angle 90 = 1[/tex]
So we get from the first two ratio equality,
[tex]\dfrac{a}{\sin \angle F} = \dfrac{c}{1} \\\\\\\dfrac{a}{\sin \angle F} = c\\\\\\\dfrac{a}{c} = sin \angle F\\\\[/tex]
Or, in other words,

I need help figuring out the measures of the missing sides
Given:
• c = 20
,• h = 15
,• j = 12
,• k = 16
Let's find the measures of the mssing sides if triangle ABC is similar to triangle JKH.
Here, the missing sides are:
Side a and Side b
Since both triangles are similar, the corresponding sides will be proportional.
To solve for the length of side a, apply the proportionality equation:
[tex]\frac{c}{h}=\frac{a}{j}[/tex]Plug in values and solve for a:
[tex]\begin{gathered} \frac{20}{15}=\frac{a}{12} \\ \\ \text{ Cross multiply:} \\ 15a=20*12 \\ \\ 15a=240 \\ \text{ } \\ \text{ Divide both sides by 15:} \\ \frac{15a}{15}=\frac{240}{15} \\ \\ a=16 \end{gathered}[/tex]Thereofore, the length of side a = 16
To solve for the length of side b, apply the equation:
[tex]\frac{c}{h}=\frac{b}{k}[/tex]Plug in the values for the variables and solve for b:
[tex]\begin{gathered} \frac{20}{15}=\frac{b}{16} \\ \\ 15b=20*16 \\ \\ 15b=320 \\ \\ b=\frac{320}{15} \\ \\ b=21.3 \end{gathered}[/tex]The length of b is 21.3

A clothing designer is selecting models to walk the runway for her fashion show.
The designer prefers models that are no more than 3 inches away from being 5'10".
Since 5'10" is the same as 70 inches, write an inequality - in terms of inches - that
could be used to determine if a model's height is within the designer's preferred height
range.
Using proportions, the inequality that could be used to determine if a model's height is within the designer's preferred height range is of:
67 inches ≤ Height ≤ 73 inches.
What is a proportion?A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication and division, from the unit rates in the context of the problem.
One example of application of proportions is for conversion of units, as there are rates for each unit.
In the context of this problem, the rate used is:
1 feet = 12 inches.
Hence the measure of 5'10" = 5 feet and 10 inches is given by:
5 x 12 + 10 = 60 + 10 = 70 inches.
The heights that are within 3 inches of 70 inches are given by:
70 - 3 = 67 inches.70 + 3 = 73 inches.Hence the inequality that models the situation is:

Answer:
Step-by-step explanation:
The apartment you want has a monthly rent of $585. What does your gross monthly income range need to be for you to be able to rent this apartment? Maximum spent on rent should be 25% - 35% of your gross monthly income
The gross monthly income range to be for you to be able to rent this apartment is $1671 - $2340.
How to calculate the value?Let the monthly income be x.
Therefore, 25% of x = 585
0.25x = 585
Divide
x = 585/0.25
x = $2340
The maximum income is $2340.
The minimum income will be:
35% of x = 585
0.35x = 585
Divide.
x = 585 / 0.35
x = $1671
In this case, the minimum value is $1671 and the maximum value is $2340. This illustrates the concept for finding the range.
The range is $1671 - $2340.

To solve the question, we will follow the steps below:
[tex]f(x)=x^2-1[/tex]To find f(f(x)), we will simply replace x by x² - 1 in the function x² - 1
That is:
f((fx)) = (x²-1)² - 1
Then we open the parenthesis
f(f(x)) = (x² - 1)(x² -1) - 1
=x²(x²-1)-1(x²-1) - 1
= x⁴ - x² - x² + 1 - 1
= x⁴ - 2x²
So the correct option is option D. which is x⁴ - 2x²

Explain how knowing the linear factor establishes that f(10) multiple of 12.
f(10) is a multiple of 12 because f(x) has a linear factor of x+2 and x+2 = 12, when x = 10
f(10) multiple of 12 is given as:
The first-degree equations that make up a polynomial's linear factors serve as the foundation stone for higher-order and more complicated polynomials. The formula for a linear factor is ax + b, and it cannot be factored further. When paired with other linear factors, each linear factor represents a separate line, resulting in several sorts of functions with progressively more intricate graphical representations.
f(10) = (10+2)(100+20+2)
= (12)(122)
= 1220+244
= 1464

A square has an area of 144 ft^2 what is the length of each side
Answer: 12 feet
This is because [tex]12^2 = 12*12 = 144[/tex]
Squaring a number means you multiply it with itself.
The square root goes in reverse to have [tex]\sqrt{144} = 12[/tex]
Answer:
Each side is 12 ft long.
Step-by-step explanation:
So, you have a square, which means all of the sides are going to be the same length. So, you need something times itself that equals 144. Or, you need the square root of 144 (Because when something is squared, it is multiplied by itself). And the square root of 144 is 12.
