Finding a sunken submarine in the middle of the ocean using Bayes' theorem to the search for USS Scorpion.
In the event of a missing vessel or aircraft at sea, in this case a submarine, Bayes search theorem can be applied.
The ocean using Bayes' theorem: the search for the Scorpion.
In May 1968, the U.S. Navy's nuclear submarine USS Scorpion (SSN-589) failed to arrive as expected at her home port of Norfolk. The command officers of the U.S. Navy were nearly certain that the vessel had been lost off the Eastern Seaboard, but an extensive search there failed to discover the remains of Scorpion.Then John P. Craven, a Navy deep-water expert, proposed that Scorpion had sunk somewhere else. Based on a contentious approximation of hydrophone triangulation, Craven organized a search southwest of the Azores. He was only given one ship, Mizar, and to make the most of his resources, he sought help from a team of consulting mathematicians. A Bayesian search approach was used. To develop theories regarding what might have led to Scorpion's loss, veteran submarine commanders were questioned.What is Bayes' theorem?
Bayes' theorem is a theorem in probability theory. It is a trivial consequence of the definition of conditional probability.Bayesian search theory is the application of Bayesian statistics to the search for lost objects.Learn more about Bayes' theorem

The z score when x=72 , μ=63 , 0=3 is z=3
Why is z-score important?Because they allow for a comparison between two scores that do not belong to the same normal distribution, z-scores are significant. They are also employed to determine the likelihood that a z-score will occur inside a normal distribution. A negative z-score indicates that the raw data is smaller than the mean.

A rectangle has a width of x centimeters and a perimeter of 8x centimeters a square has sides of length 1/4 that of the length of the rectangle.
Find the perimeter of the square
The perimeter of the square is calculated to be (8 - x) cm
How to find the perimeter of the squareThe perimeter of a square is calculated using the formula
= 4 * length
From the problem we have that the length of the square
= 1/4 length of rectangle
perimeter of rectangle
8 = 2(Length + width)
dividing through by 2
4 = L + w
substituting w = x
8 = L + x
L = 8 - x
length of square = 1/4 * 8- x = (8 - x)/4
perimeter of a square = 4 * (8 - x)/4

Marvin is about to play tag with his friend Paul in a circular field. Paul is away from Joshua, and the field has a diameter of 12m. How far is the distance between the two friends?
Distance between Marvin and Joshua is less or equal to 12 meter.
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given,
Marvin and Joshua are about to play in a circular field.
Diameter of the field D = 12m
Let distance between two friends is x
Since, Diameter is the longest chord in a circle
Thus, x ≤ D
Distance between two friends ≤ 12 meter.

What is the value of exponential 4?
The value of exponential 4 is 4^4, or 256. it means that 4 should be multiplied by itself 4 times.
In mathematics, an exponential is a number that is multiplied by itself a certain number of times. For example, when 4 is used as an exponential, it means that 4 should be multiplied by itself 4 times. This is written as 4^4, or 4 to the fourth power. This means that 4 is multiplied by itself 4 times, resulting in the value of 256.
Exponentials can be used to calculate the power of a number. For example, in the case of 4^4, 4 is the base number and 4 is the exponent. An exponent is the number of times a base number is multiplied by itself. In this case, the base number (4) is being multiplied by itself 4 times, resulting in a value of 256.
In addition, exponentials can be used to solve equations. For example, if we need to solve for x in the equation 4^x = 256, we can use the exponential 4 to determine the value of x. In this case, x = 4 because 4^4 = 256.

D. Use 2 digit numbers 00-99, let 00-?? represent babies born with birth defects, #??-?? Represent babies born without a major defect, and skip #??-99
This is equal to 0.04 plus 1.96 into root over 0.04 into 0.96 divided by 400 point. This is equal to 0.059, which is equal to 5.9 percent. Therefore, double 0 to 5.9 percent represent babies born with defect.
What is the Justification for the above?According to one research, 28 out of every 400 kids born in the globe suffer some form of serious birth problem. To execute a simulation based on this data, the easiest approach to assign random numbers is to use 00-06 (7%) to identify the newborns with birth abnormalities.
It is to be noted that:
The sum total of births is: 400
The sum of defective babies = 28
Hence, the fraction or ratio of this is:
28/400
= 7/100
= 7%.
The implication here is that that 07-99 (93%) will represent the babies without birth defects.

The total cost of a pair of sandals is given by the equation A = $ 18.39
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of pair of sandals be represented as A
Now , the equation will be
The total amount spent by Bonnie = $ 77.77
The cost of one shirt = $ 11.49
So , the cost of 2 shirts = 2 x 11.49 = $ 22.98
And , the cost of 1 pair = $ 32
The total tax on the purchase = $ 4.40
So , the cost of pair of sandals A = total amount spent by Bonnie - cost of 2 shirts - cost of 1 pair - total tax on the purchase
Substituting the values in the equation , we get
The cost of pair of sandals A = 77.77 - 22.98 - 32 - 4.40

We can use an equation to solve this problem.
Let x = number of ales Marhall made
Marhall's Earnings = 186 + (15 x)
Vickie's Earnings = 48 + (18 x)
Since both of them earned the same amount, we can set up the equations and solve for x:
186 + (15 x) = 48 + (18 x)
15x = 138
x = 9

Given that;
John is driving around town. When he reaches the gas station, he notes that he has traveled 11 miles.
And, He reaches home 2 hours later and notes that he has traveled 30 miles.
Now, Let d represents the distance and t represents the time, in hours
So we get;
Let the equation which model this situation,
⇒ d = a t + b
Where a and b are constant.
Let the gas station is the starting point.
So, at gas station t = 0 , d = 11
Hence,
⇒ 11 = 0 × a + b
⇒ b = 11
When he reaches home 2 hours later notes that he has traveled 30 miles.
And, with substituting with b = 20

Calculate the probability that a random sample of 50 cans produces a sample mean amount of 11.9 ounces or less.
Previous question
a. We cannot calculate the probability, because we do not know the shape of the distribution.
b. The mean and standard deviation of the sampling distribution of x are 12 and 0.0566.
c. The shape of the distribution described in part b is symmetrical.
d. The probability that a random sample of 50 cans produces a sample mean amount of 11.9 ounces or less is 0.0386.
We do not know the shape of the distribution, so we cannot calculate the probability that a single randomly selected can contains 11.9 ounces or less. The question given have not told us that the distribution of individual cans was normal, and we cannot assume it is so; therefore, we cannot calculate its probability.
As given information the mean μx = 12.
And standard deviation σx = σ / √n = 0.4 / √50 = 0.566.
The shape of the distribution described in part b is symmetrical, because the two sides of the distribution are a mirror image of each other. Therefore, it is normal distribution.
Since the sample is large n = 50 and 50 > 30, so by CLT (Central Limit Theorem), the distribution of sample means is approximately normal N(12, 0.0566). So, P(x ≤ 11.9) = normalcdf (0, 11.9, 12, 0.0566) = 0.0386.
