Answer:
Delta Airlines: 783 miles in 3 hours = 261 miles per hour
American Airlines: 510 miles in 2 hours = 255 miles per hour
Southwest Airlines: 1,230 miles in 5 hours = 246 miles per hour
Step-by-step explanation:
American Airlines: 510 miles in 2 hours
Miles per hour = Total miles travelled / number of hours taken
= 510 miles / 2 hours
= 255 miles per hour
Delta Airlines: 783 miles in 3 hours
Miles per hour = Total miles travelled / number of hours taken
= 783 miles / 3 hours
= 261 miles per hour
Southwest Airlines: 1,230 miles in 5 hours
Miles per hour = Total miles travelled / number of hours taken
= 1,230 miles / 5 hours
= 246 miles per hour
Order the airlines with the fastest airline on top, and the slowest airline on bottom
Delta Airlines: 783 miles in 3 hours = 261 miles per hour
American Airlines: 510 miles in 2 hours = 255 miles per hour
Southwest Airlines: 1,230 miles in 5 hours = 246 miles per hour

The overhead reach distances of adult females are normally distributed with a mean of 205.5 and a standard deviation of 8.6 . a. Find the probability that an individual distance is greater than 218.00 cm. b. Find the probability that the mean for 15 randomly selected distances is greater than 204.00 c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
Answer:
a) 0.073044
b) 0.75033
c) The normal distribution can be used in part (b), even though the sample size does not exceed 30 because initial population size is been distributed normally , therefore, the mean of the samples will be normally distributed regardless of their size(meaning whether the sample size is less than or equal to or exceeds 30, the sample means the mean of the samples will be normally distributed regardless of their size).
Step-by-step explanation:
The overhead reach distances of adult females are normally distributed with a mean of 205.5 and a standard deviation of 8.6 .
a. Find the probability that an individual distance is greater than 218.00 cm.
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 218
μ is the population mean = 205.5
σ is the population standard deviation = 8.6
For x > 218
z = 218 - 205.5/8.6
z = 1.45349
Probability value from Z-Table:
P(x<218) = 0.92696
P(x>218) = 1 - P(x<218) = 0.073044
b. Find the probability that the mean for 15 randomly selected distances is greater than 204.00
When = random number of samples is given, we solve using this z score formula
z = (x-μ)/σ/√n
where
x is the raw score = 204
μ is the population mean = 205.5
σ is the population standard deviation = 8.6
n = 15
For x > 204
Hence
z = 204 - 205.5/8.6/√15
z = -0.67552
Probability value from Z-Table:
P(x<204) = 0.24967
P(x>204) = 1 - P(x<204) = 0.75033
c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?
The normal distribution can be used in part (b), even though the sample size does not exceed 30 because initial population size is been distributed normally , therefore, the mean of the samples will be normally distributed regardless of their size(meaning whether the sample size is less than or equal to or exceeds 30, the sample means the mean of the samples will be normally distributed regardless of their size).

y = [tex]sin^{-1}x[/tex] function is represented in the graph.
What is inverse sine function?The inverse sine function (also called arcsine) is the inverse of sine function. Since sine of an angle (sine function) is equal to ratio of opposite side and hypotenuse, thus sine inverse of same ratio will give the measure of the angle.
According to the graph
Domain = [-1, 1]
Range = [-[tex]\frac{\pi }{2}[/tex], [tex]\frac{\pi }{2}[/tex]]
Restrict the domain of the sine-function y =sinx, so that it is one to one, and not infinite by setting an interval [-[tex]\frac{\pi }{2}[/tex], [tex]\frac{\pi }{2}[/tex]].
The restricted function passes the horizontal line test, therefore it is one to one .
Each range value (-1 to 1) is within the limited domain (-[tex]\frac{\pi }{2}[/tex], [tex]\frac{\pi }{2}[/tex]).
Inverse sine function:Inverse sine or arcsine is the inverse of the restricted sine function , y =sinx, [-[tex]\frac{\pi }{2}[/tex], [tex]\frac{\pi }{2}[/tex]].
The equation is y = [tex]sin^{-1}x[/tex] or y = arc sinx
Which also means , siny = x, where -[tex]\frac{\pi }{2}[/tex] ≤ y ≤ [tex]\frac{\pi }{2}[/tex], -1 ≤ x ≤ 1.
The coordinates of the inverse sine function (-1, -[tex]\frac{\pi }{2}[/tex]), (0, 0), (1, [tex]\frac{\pi }{2}[/tex]).
Thus, y = [tex]sin^{-1}x[/tex] function is represented in the graph.

What is the value of x knowing that the interior angle of this regular polygon is (-134x+516+2x)?
Based on the calculations, the value of x for this regular polygon with the given interior angle is equal to 3.
What is a polygon?A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides. Also, some examples of a polygon include the following:
TriangleQuadrilateralPentagonHexagonNonagonOctagonNote: The number of sides (n) of a hexagon is 6.
In Geometry, the sum of the interior angles of both a regular and irregular polygon is given by this formula:
Sum of interior angles = 180 × (n - 2)
Sum of interior angles = 180 × (6 - 2)
Sum of interior angles = 180 × 4
Sum of interior angles = 720°.
Next, we would determine the value of x by using this formula:
Interior angle × Number of sides = Sum of interior angles
Substituting the parameters into the formula, we have;
(-134x + 516 + 2x) × 6 = 720
-134x + 516 + 2x = 720/6
-134x + 516 + 2x = 120
516 - 120 = 134x - 2x
396 = 132x
x = 396/132
x = 3.

Answer:
Slope= 4
Step-by-step explanation:
When you start at (0, 0) and then go to (1, 4), then you have to use the slope.
So, to figure out the slope, you have to do rise over run, rise/run.
So, as shown in the graph, the rise is 4 because the rise is the y so to get from 0 to 4, you have to add 4.
And the run, which would be the x side is 1 because to get from 0 to 1. You add 1.
This shows us that the slope is 4/1 which could be simplified to just 4.

I don't know how to answer question 1, but the answer from question 2 is x=5
Step-by-step explanation:
The triangle shown is an isosceles triangle because it has two congruent sides. The base angles of isosceles triangles are congruent so ∠y=∠x. since the ∠x is 52 the ∠y is also 52. We subtract the measure of angles x and y in order to find the measure of the third angle. 180-(52+52) or 180-104 is 76. this means that 14x=6=76. All we have to do to get the answer now is solve. 76-6 is 70 and 70 divided by 14 is 5. x=5.

can someone plz help me with this question: select the correct answer. what is √125 in simplest form?
Answer: First Option (5√5)
Answer:
First, you see if there are any perfect squares that are a factor of 125. If you do find some, find what is seemingly the biggest. In this case, it is 25, I think. So you can then out it as root(25×5), I think. As 25 is a perfect square, you can square and then put the number you get on the outside. So since 5×5=25, it becomes 5(root)5, which essentially means 5×(root)5, I think.
Carter stated that 5(x + 9) - 3x is the same as 2x + 45. Lori disagreed with him and said that an equivalent expression is 2x + 9. Who was right?
Answer:
Carter;
5 ( x + 9 ) - 3x = 2x + 45
Step-by-step explanation:
Simplify the equation;
5 ( x + 9 ) - 3x
Distribute the 5, remember, you have to distribute 5 over both terms.
5x + 45 - 3x
Combine like terms;
2x + 45
