the probability that a restaurant passes its health department inspection is 0.94. the owners of 58 restaurants are surveyed to see if their restaurants passed inspection. For each binomial experiment described, find the mean, the variance and the standard deviation!
The mean , standard deviation, and the variance of each binomial experiment using given probability and sample of restaurant owners surveyed is equal to 54.52 , 1.808, 3.2712 respectively.
As given in the question,
Let success be defined by health department inspection is passed by restaurant
Probability of success rate 'p' = 0.94
Value of ' 1 - p ' = 1 - 0.94
= 0.06
Number of owners of restaurant which are surveyed 'n' = 58
For the given binomial experiments calculation of the following distributions are:
Mean 'μ' = np
= 58 × 0.94
= 54.52
Standard deviation 'σ' = √ np (1 - p)
= √ 58 × 0.94 × 0.06
= √3.2712
= 1.808
Variance 'σ²' = np( 1 - p )
= 58 × 0.94 × 0.06
= 3.2712
Therefore, the mean , standard deviation , and the variance from the given probability and sample size is equal to 54.52 , 1.808, 3.2712 respectively.

a regional director responsible for business development in the state of pennsylvania is concerned about the number of small business failures. if the mean number of small business failures per month is 14, what is the probability that exactly 5 small businesses will fail during a given month? assume that the probability of a failure is the same for any two months and that the occurrence or non occurrence of a failure in any month is independent of failures in any other month. (round your answer to four decimal places.) g
The probability that exactly 5 small businesses will fail during a given month 0.0037268.
The Poisson distribution would be used to calculate the likelihood that different counts of the same event will occur within a constrained time period. It is viewed as a discrete distribution since it evaluates counts. The distribution displays identical mean and dispersion values.
The pmf of the Poisson distribution is
[tex]p(x)=\frac{e^{\lambda} \lambda^{x}}{x!}[/tex]
The mean total number of small business failures λ=14
Let x represent the number of failed small businesses in a given month.
X~P(14)
X follows the Poisson distribution since the likelihood of failure stays constant for two months and the mean number of failures per month is 14.
The likelihood that precisely four small firms would fail in a given month must be calculated.
P(X=5)
[tex]P(X=5)= \frac{e^{14} \ 14^{5}}{5!}[/tex]
P(X=5)= 0.44721/5!
P(X=5)=0.0037268.
In a month there is 0.0037 that is 3.7% probability that a small business fail.

The value of the equation 3d/ac x 2ad/30 is ( d² / 5c )
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 equation be represented as A
Now , the value of A is given by
A = 3d/ac x 2ad/30 be equation (1)
On simplifying the equation , we get
A = 3d/ac x 2ad/30
A = 6ad² / 30ac
On further simplification of the equation , we get
The value of A = 1/5 ( ad² / ac )
The value of A = 1/5 ( d²/c )
Therefore , the value of A is ( d² / 5c ) or A = 1/5 ( d²/c )
Hence , The value of the equation 3d/ac x 2ad/30 is ( d² / 5c ) or

a local winery bottles 14 different white wines. to help customers with their purchasing choice, the winery offers customers 5 white wine tasting samples free of charge 2002 many ways does a customer have to choose 5 different white wines to taste, using the concept of combination formula.
What is combination formula?The number of possible ways to choose items from a collection when the order of choice is irrelevant is determined using the combination formula. Combination, to put it simply, is the process of choosing items or things from a bigger group where order is irrelevant.
The combination formula is: n! / (n-r)! r! , where n is the total number of items (14 in this case) and r is the number of items being selected at once (5 in this case),
Plugging our numbers into the formula we get:
= 14! / (14-5)! 5!
= 2002

A rectangle is constructed on a semicircle so that the length equals the diameter. The rectangle is 3 times as long as it is wide. The total area of the figure is 750 inches squared. Find the approximate dimensions of the rectangle.
A rectangle is constructed on a semicircle so that the length equals the diameter. The width of the rectangle is approximately 10.65 inches.
What are the approximate dimensions of the rectangle.?Generally, Let the width of the rectangle be x. Then the length of the rectangle is 3x.
The diameter of the semicircle is also the length of the rectangle, so it is 3x.
The area of the rectangle is x*(3x) = 3x^2. The area of the semicircle is (1/2)πr^2, where r is the radius of the semicircle. Since the diameter of the semicircle is 3x, the radius is (3x)/2. The area of the semicircle is (1/2)π((3x)/2)^2 = (9/8)πx^2.
The total area of the figure is the sum of the area of the rectangle and the area of the semicircle. We can set up the equation:
3x^2 + (9/8)πx^2 = 750
(21/8)πx^2 = 750
x^2 = 750/(21/8)*π
x = √(750/(21/8)*π)
To find the approximate dimensions of the rectangle, we can use the fact that pi is approximately 3.14. This gives us:
x = √(750/(21/8)*3.14)
= √(750/6.71)
= √(112.64)
= approximately 10.65 inches.
The width of the rectangle is approximately 10.65 inches. The length of the rectangle is 3 times the width, so it is approximately 31.95 inches.

What are mathematical operations?
A mathematical "operation" is indeed the method by which a value utilizes operands and a math operator.
The supplied operands or numbers must conform to a set of predefined rules that are connected to the symbol of the math operator.
Parentheses, Exponents, Arithmetic, Division, and Addition Simple arithmetic is also known as PEMDAS (from left to right).
So, we know that the given triangles are similar:
Then, the length of line LK will be:
JK/ST = LK/UT
Solve this as follows:
JK/ST = LK/UT
2.5/10 = LK/5
10LK = 2.5(5)
10LK = 12.5
LK = 12.5/10
LK = 1.25

find y and x
Answer:
a) y = 16/x²
b) x = 4/5
Step-by-step explanation:
You want the equation for y in terms of x when y is inversely proportional to the square of x, and y is 16 when x is 1. Further, you want the value of x when y is 25.
(a) RelationThe wording "inversely proportional to the square" means the form of the equation is ...
y = k/x² . . . . . . where k is the constant of proportionality
The value of k can be found from the given (x, y) pair.
k = x²y = (1)²(16) = 16
The equation is ...
y = 16/x²
(b) Value of xSolving for x gives ...
x = √(16/y)
Then the value of x for y = 25 is ...
x = √(16/25)
x = 4/5

A exam and an assignment were due on the same day in a math class with 19 pupils.
There were 14 students that finished the assignment, and 11 of them completed the test.
3 pupils both failed the exam and didn't finish the assignment.

The number of the student who has done at least one assignment or passed the test is 19 - 3 = 16
n(A) = passes student
n(B) = given assignment
Then we have
n(A ∩B) = n(A) + n(B) - n (A ∪B )
n(A ∩B) = 11 + 14 - 16
n(A ∩B) = 9
