The array that has been sorted using insertion sorting 1 2 3 4 5 6 7 8 9.
A straightforward sorting algorithm called insertion sort functions like how you might arrange playing cards in your hands.
Initial Pass: 2 9 8 7 6 5 1 4 3
The array's first two members are initially compared using an insertion sort.
Since 9 is bigger than 2, they are not arranged in ascending order, and 2 is not in the proper place. So, switch 9 and 2.
Therefore, 2 is currently kept in a sorted sub-array.
Second Pass: Continue with the next two elements and compare them.
2 8 9 7 6 5 1 4 3
Here, 9 is bigger than 8, therefore both items appear to be in ascending order; as a result, there won't be any switching. Along with 8, 9 is also kept in a sorted sub-array.
Third pass: Currently, the sorted sub-array has two entries, which are 2 and 8.
Moving on to the following two components, which are 9 & 7,
2 7 8 9 6 5 1 4 3
Continue sorting similarly; the results would be 1 2 3 4 5 6 7 8 9.

Joey ha 8 pair of ock in hi drawer. Five of the pair are white. What percent of joey ock are colored?
Using percentages, we know that Joey has 37.5% of colored pairs of socks.
What is the percentage?%, which is a relative figure used to denote hundredths of any quantity.
Since one percent (symbolized as 1%) is equal to one-hundredth of something, 100 percent stands for everything, and 200 percent refers to twice the amount specified.
Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance.
Finding the percentage of a whole in terms of 100 is what percentage calculation is.
Both manual calculation and the use of internet calculators are options.
So, the percentage of colored pair of socks are:
We know that Joey has a total of 8 pairs of socks.
We also know that 5 pairs of socks are white.
Hence, the colored pair of socks will be:
8 - 5 = 3
Calculate its percentage as follows:
3/8 * 100
0.375 * 100
37.5%
Therefore, using percentages, we know that Joey has 37.5% of colored pairs of socks.

how do the results compare to your hypothesis? explain why your hypothesis was or was not supported by the results.
To compare result to hypothesis, we will start by providing the key result from the each model and then compare and contrast them.
A hypothesis is usually a prediction based on some evidence. Hypothesis must be tested and once tested they can be supported by evidence if a statement is made that cannot be tested or disproof then it is not hypothesis
To compare we will start by providing the key result from the each model and then compare and contrast them then you can then provide any interpretation or future direction to some of the comparison
To prove or disprove your hypothesis you need to be able to do an experiment and take that measurement or make observation to see how two things are related
If you have hypothesis is not supported by the result of the experiment you should really realize the data in order to figure out why your result disprove your hypothesis
You should not alter the observation or experiment so that you reserve proof your hypothesis

Enter your answers as numbers accurate to 4 decimal places.
The probability that a single randomly selected value is more than 987 dollars is 0.5664
We know that probability is defined as the ratio of number of favorable outcomes to the total number of outcomes.
We know very well that z-value is calculate by the formula
z = (X-μ) / σ/√n
where z is the z-value,
X is randomly selected value,
μ is standard mean
σ is standard deviation and
n is the sample size.
For, X=987
=>z = (987-1037) / (243/√69)
=>z= -50 / (243 / 8.33)
=>z = -50 / (29.171)
=>z= -1.714
Now, we need to find the probability of A>987,so,we need to find what is the probability of A<=987.
P(X>987)= 1-P(X≤987)
=>P(X>987)=1-P(z<(-1.714))
Using the z-table ,we get that P(z<(-1.714))=0.43353
Therefore, P(X>987)=1-0.43353=0.5664

Answer:
[tex]\textsf{1)\quad 48\;inches}[/tex]
[tex]\textsf{2)\quad$2\sqrt[3]{3}$\; inches}[/tex]
Step-by-step explanation:
Question 1Define the variables:
Let x be the length of the string.Let y be the rate of vibration of a string under constant tension.The rate of vibration of a string under constant tension varies inversely with the length of the string:
[tex]\boxed{y \propto \dfrac{1}{x} \implies y=\dfrac{k}{x}\quad\text{for a constant $k$}}[/tex]
Given values:
x = 24 inchesy = 128 times per secondSubstitute the given values of x and y into the formula and solve for k:
[tex]\implies 128=\dfrac{k}{24}[/tex]
[tex]\implies k=128 \cdot 24[/tex]
[tex]\implies k=3072[/tex]
Therefore, the equation is:
[tex]y=\dfrac{3072}{x}[/tex]
To find the length of a string that vibrates 64 times per second, substitute y = 64 into the equation and solve for x:
[tex]\implies 64=\dfrac{3072}{x}[/tex]
[tex]\implies x=\dfrac{3072}{64}[/tex]
[tex]\implies x=48[/tex]
Therefore, the length of a string that vibrates 64 times per second is 48 inches.

Question 2Define the variables:
Let y be the horsepower (hp) that a shaft can safely transmit.Let v be the speed of the shaft (in rpm).Let d be the diameter of the shaft (in inches).The horsepower that a shaft can safely transmit varies jointly with its speed and the cube of the diameter:
[tex]\boxed{y \propto vd^3 \implies y=kvd^3\quad\text{for a constant $k$}}[/tex]
Given values:
y = 45 hpv = 100 rpmd = 3 inchesSubstitute the given values of y, v and d into the formula and solve for k:
[tex]\implies 45=k \cdot 100 \cdot 3^3[/tex]
[tex]\implies 45=k \cdot 100 \cdot 27[/tex]
[tex]\implies 45=2700k[/tex]
[tex]\implies k=\dfrac{45}{2700}=\dfrac{1}{60}[/tex]
Therefore, the equation is:
[tex]y=\dfrac{vd^3}{60}[/tex]
To find the diameter of the shaft in order to transmit 60 hp at 150 rpm, substitute y = 60 and v = 150 into the equation and solve for d:
[tex]\implies 60=\dfrac{150d^3}{60}[/tex]
[tex]\implies 3600=150d^3[/tex]
[tex]\implies d^3=\dfrac{3600}{150}[/tex]
[tex]\implies d^3=24[/tex]
[tex]\implies d=\sqrt[3]{24}[/tex]
[tex]\implies d=\sqrt[3]{8 \cdot 3}[/tex]
[tex]\implies d=\sqrt[3]{8} \sqrt[3]{3}[/tex]
[tex]\implies d=\sqrt[3]{2^3} \cdot \sqrt[3]{3}[/tex]
[tex]\implies d=2\sqrt[3]{3}[/tex]
Therefore, the diameter of a shaft that transmits 60 hp at 150 rpm is 2³√3 inches.

three points are chosen randomly and independently on a circle. what is the probability that all three pairwise distances between the points are less than the radius of the circle?
There is a 1/12 chance that the three pairwise distances between the locations are smaller than the radius of the circle.
Here,
The first point can be placed anywhere on the circle because it doesn't matter where it is chosen.
A total of 120 degrees and a probability of 1/3 must be provided by the next point, which must be within an arc of 60 degrees on either side. The second point must be 60 degrees or less from the first two.
The third point can be located within an arc with a minimum area of freedom of 60 degrees and a chance of 1/6 if the first two locations are separated by 60 degrees. The third point can be located with a maximum degree of freedom of a 120 degree arc and a 1/3 chance if the first two points are the same.
Up to a maximum of 60 degrees away from the starting point, the likelihood changes linearly.
By averaging the probabilities at either end, we may discover 1/4, the typical likelihood we can position the third point based on a fluctuating second point.
The overall probability is 1 1/3 4 = 1/12.
