The train has 12 carriages
Step-by-step explanation:
The total no. of seats =876
No. of seats per carriage =73
It is given that each carriage has equal seats
So,
Let the total no. of carriages be x
According to the given information,
[tex]73 \times x = 876[/tex]
[tex]x = 876 \div 73[/tex]

Barry has a medical plan with a $1,000 deductible, 20% coinsurance, and a $5,000 coinsurance cap. His allowable medical expenses during the past year are $18,000. How much of this amount will he have to pay out of pocket?.
Based on his deductible and coinsurance cap, the amount that Barry will pay is $4,560.
Barry will pay x amount.
Barry will be responsible for covering the entire $1,200 deductible. The remaining costs will subsequently be split between him and the insurer in a ratio of 20% to 80%, although he will not be required to pay more than $5,000.
He will consequently pay the following total out of pocket:
= Deductible + ( 20% x (Medical expenses - deductible)
Solving gives:
= 1,200 + ( 20% x (18,000 - 1,200))
= $4,560
He will pay $4,560 in total.

Lines l and m are parallel.
Which statement is always true?
Group of answer choices
A 90° rotation will map line l onto line m.
Line l can be reflected over a horizontal line to map onto line m.
Line l can be reflected over a vertical line to map onto line m.
Line l can be translated to map onto line m.
Lines l and m are parallel; line l will map onto line m with a 90° rotation; line l can map onto line m with a vertical line of reflection.
Do you have any explanations as to why the lines L and m are parallel?L and m are not parallel because the sum of the co-interior angles on the same side of the transversal does not equal 180 degrees.In the event when two lines, l and m, are in the same plane but do not cross, they are said to be parallel.We are aware that the equivalent angles are equal if they are parallel and a transversal is drawn to intersect them both. Accordingly, these are x and y. As a result, we can conclude that x and y are equivalent if l and m are parallel.If two lines, l and m, are in the same plane and do not cross one another, then they are parallel.To learn more about Lines refer to:

A. Triangle AEB is congrent to Triangle CDB by Side - Angle Side.
B. Triangle AEB is congrent to Traingle CDB by Side- Side - Side.
C. The two triangles are not necessarily congruent. There is not enough information.
The triangles ΔAEB and ΔCDB are congruent as per SSS criteria. The correct option is (B).
What are the criteria for congruent triangles?Two triangles are said to be congruent when all of their corresponding sides and angles are equal. For this relation between two triangles, there are many criteria such as SSS, SAS, ASA and RHS.
The relation between the two triangles ΔAEB and ΔCDB as per the given information can be shown as follows,
In ΔAEB and ΔCDB,
AE = CB
AB = CD
EB = BD
Since all the three corresponding sides of the triangles are equal, the triangles ΔAEB ≅ ΔCDB by SSS criteria.

An airplane is preparing to land at an airport. It is 35,400 feet above the ground and is descending at the rate of 3,300 feet per minute. At the same airport,another airplane is taking off and will ascend at the rate of 2,600 feet per minute. When will the two airplanes be at the same altitude and what will that altitude be?
They will be at the same altitude in minutes, when their altitude will be feet.
The time at which the planes are at the same height is given as 6 minutes.
How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
The expression for the height of the two airplanes in terms of time t is given as,
For the first airplane it is 35400 - 3300t,
And, for the second it is 2600t.
When, the two airplanes are at the same height the following equation can be written,
35400 - 3300t = 2600t
=> 35400 = 3300t + 2600t
=> 5900t = 35400
=> t = 6
Hence, both the planes are at the same height after 6 minutes.

If f(x) = x² - 1, and g(x) = x + 2, then g(f(x)) = [?]x² +
please explain
Answer:
g(f(x)) = x² + 1.
Step-by-step explanation:
To evaluate g(f(x)), we need to first evaluate f(x) and then plug the result into g(x). Since f(x) = x² - 1, we have g(f(x)) = g(x² - 1). Plugging this into g(x), we get g(x² - 1) = (x² - 1) + 2. So the final result is g(f(x)) = x² + 1.
Here's a step-by-step breakdown:
g(f(x)) = g(x² - 1) [substitute f(x) = x² - 1]g(f(x)) = (x² - 1) + 2 [substitute g(x) = x + 2]g(f(x)) = x² + 1 [simplify]Note that this is only the case if f(x) and g(x) are defined for all values of x. If either function is only defined for certain values of x, then the result of g(f(x)) will depend on the specific input value used.

To round the decimal, we need to look at the number in the tenths place. If it is less then 5, we round down. If it is greater or equal to 5, we round up. Since the number in the tenths place is 1, we round down, to 246.
suppose the time it takes a nine-year old to eat a donut is uniformly distributed between 0.5 and 4 minutes, inclusive. what is the probability that a nine year old will take longer than 3 minutes to eat a donut? ( round to three decimal places)
The probability that a nine year old will take longer than 3 minutes to eat a donut is 0.667 .
Given that the time taken by 09 years old,
Consider that it takes 0.5 to 4 minutes inclusive for a 9-year-old to eat a donut.
Let X = Time
minutes, how long it takes a 9 year old to eat a donut.
Then X: U(0.5, 4).
The Probability Distribution Function:
P(X) = 1/4 - 0.5 = 0.2857
Cumulative Function would be:
F(x) = x -0.5 /0.5
The probability that a randomly selected 9-year-old child will eat a donut in at least 2 minutes is
P(X ≥ 2) = 1 -F(2)

The complete statement is:
In ΔFGH, the measure of m∠F=54°, the measure of m∠G=90°, and m∠H = 36°
How to complete the missing blank?From the question, we have the following parameters that can be used in our computation:
Triangle = ΔFGH, The measure of m∠F = 54°The measure of m∠G = 90°The sum of angles in a triangle is 180°
So, we have the following representation
m∠F + m∠G + m∠H = 180°
Substitute the known values in the above equation, so, we have the following representation
54 + 90 + m∠H = 180°
Evaluate the sum in the above equation
This gives
144 + m∠H = 180°

on february 13, a jewelry store sells an engagement ring with a sales price of $10,000 to a nervous young man, who pays in cash. the sale is subject to a 9.75 percent sales tax.
The total cost of the engagement ring is $10,975. The sales tax is calculated as follows: $10,000 x 0.0975 = $975.
Why does sales tax matter?A sales tax is a type of consumption tax that local or state governments apply on the sale of products or services that consumers pay for when they make a purchase. When a company has a link to the jurisdiction in some way, it is responsible for collecting sales tax and remitting payment to the government.
How is sales tax collected?It is only imposed and paid when the taxable supply is produced while engaging in a "taxable activity". Taxes should be based on the value of the goods or service. Because of the way the sales tax is structured, consumers are required to bear the majority of the tax burden. Because sales tax is an indirect tax, this is true.

How to predict the city that the home is in?
We are given the linear regression equations for each town, which predicts the value of a home with a square feet.
Then the prediction of the city is given by the one whose prediction for a input of 2800 square feet gives the least residual relative to 280, that is, the value that has the least absolute difference relative to 280.
For Smaville, the equation is given as follows:
p = 150 + 0.041a.
Hence the estimate of the cost for a estate with 2800 square feet is of:
p = 150 + 0.041(2800) = 264.8.
For Fancyville, the equation is given as follows:
p = 250 + 0.198a
Hence the estimate of the cost for a estate with 2800 square feet is of:
