Train tracks are made of metal. Consequently, they expand when it's warm and shrink when it's cold. When riding in a train, you hear the clickety-clack of the wheels going over small gaps left in the tracks to allow for this expansion. Suppose you were a beginner at laying railroad tracks and forgot to put in the gaps. Instead, you made a track 01 mile long that was firmly fixed at each end. On a hot day, suppose the track expanded by A = 8 feet and therefore buckled up in the middle, creating a triangle.
The height of the triangle that forms the train track is 145,38 ft
How to calculate the height of the triangle?To calculate the height of the triangle we must take into account the information provided by
Base of the triangle = 1 mile = 5280 feetRailroad track expansion = 8 feetAccording to the above, we must perform the following operations:
5280 ÷ 2 = 26408 ÷ 2 = 42640 + 4 = 2644
Subsequently, we must apply the Pythagorean theorem to find the height of the triangle having 2 data:
Base: 2640ftHypotenuse: 2644 ft2644² = x² + 2640²x² = 2644² - 2640²x = [tex]\sqrt[2]{2644^{2} + 2640^{2}}[/tex].x = [tex]\sqrt[2]{21137}[/tex]x = 145,38 ftThat makes x approximately 145,38 ft.

A roll of film for this camera costs $4.79. There
are 16 shots on the roll. It costs $12.17 to get
the film developed. What is the total cost of the
16 photos? How much does each snapshot cost
including the film and the developing?
Answer:
The total cost is $16.96
The cost per photo is $1.06
Step-by-step explanation:
Hello!
Part 1:1 roll of film costs $4.79. 1 roll of film has 16 photos. To develop the 16 photos, you need to pay $12.17.
First, let's find the total cost for the film and the development for 1 roll of film:
Total Cost = Cost of Film + Cost of developingTotal Cost = $4.79 + $12.17Total Cost = $16.96The total cost of 16 photos is $16.96
Part 2:Now, we have to find the price per picture on the roll of film. We know that there are 16 shots on the film, so we can simply divide the total price by 16 to find the price per picture.
Divide:
$16.96 ÷ 16($16 ÷ 16) + ($0.96 ÷ 16)$1 + $0.06$1.06The price per photo is $1.06

-y = 2(x - 2)
-y = 2x - 4
y = -2x + 4
»(y + 0)/4 = (x - 2)/(0 - 2)
»y/4 = (x - 2)/(-2)

List all 10 possible SRSs of size n = 2, calculate the mean number of wings eaten for each sample, and display the sampling distribution of the sample mean on a dotplot.
Is the sample mean an unbiased estimator of the population mean? Justify your answer.
If we increase the sample size, does the variability of the sampling distribution change? Explain
The sampling computed simply illustrates that the population mean will be 20.
How to solve the samplingIt should be noted that the population mean will be calculated thus:
= (6 + 24 + 18 + 20 + 32)/5
= 100/5
= 20
It can be deduced that the sample mean is an unbiased estimator of the population mean.
Lastly, when there's an increase in the sample size, the variability of the sampling distribution change. This is because there's a reduction.

Compare the volumes of the right prism and the oblique prism. Explain.
Look at the picture to answer.
Also this is worth 100 points(you get 50, and more if your answer is good and I Brainliest you (if that makes any sense))
Answer:
Both of the volumes are equal.
Step-by-step explanation:
Since both figures have the same base and have the same heights, the figures have equal volumes. If the height of the oblique prism was not outside of the figure and was instead the diagonal line, the volumes would not be the same. Rectangular prisms and oblique prisms are only equal when their bases (l*w) and the heights are equal, and the heights are only equal if the height of the oblique prism is outside of the figure, as shown in the image.
Answer:
They are the same.
Step-by-step explanation:
Since the height of the slanted prism is the same height as the regular one, the volumes work out. Even if slanted the formula is STILL lengthxwidthxheight.

A rectangle has an area of 342 square meters. The width is 2 more than 4 time the length. Find the length and width, in meters of the rectangle
Answer:
length: 9 mwidth: 38 mStep-by-step explanation:
Let x represent the length of the rectangle. The the width is (4x+2) and the area is ...
x(4x+2) = 342
2x² +x - 171 = 0 . . . . . divide by 2, rearrange to standard form
(2x +19)(x -9) = 0 . . . factor
x = -19/2 or +9 . . . . . the length is the positive solution: 9
(4x+2) = 4(9) +2 = 38 . . . . find the width from the length
The length of the rectangle is 9 meters. The width is 38 meters.
