Step-by-step explanation:
By some miracle, a Smudgy Press book is found to have 90% of its pages free of typographic errors. Assuming that the distribution of the typographical errors per page is Poisson, what is the probability that a randomly selected page contains exactly one error
Answer:
The value is [tex]P(X = 1 ) = 0.0948[/tex]
Step-by-step explanation:
From the question we are told that
The the probability that the Smudgy Press book pages have zero errors [tex]p = 0.90[/tex]
Gnerally the probability distribution for Poisson distribution is
[tex]P(X = x) = \frac{\lambda ^x * e^{-\lambda}}{x!}[/tex]
Gnerally the probability that the Smudgy Press book pages have zero errors is mathematically represented as
[tex]P(X = 0) = \frac{\lambda ^0 * e^{-\lambda}}{0!} =p= 0.90[/tex]
=> [tex]e^{-\lambda} =p= 0.90[/tex]
taking natural log of both sides
[tex]ln (e^{-\lambda}) = ln(0.90)[/tex]
=> [tex]-\lambda = -0.1054[/tex]
=> [tex]\lambda = 0.1054[/tex]
Generally the probability that a randomly selected page contains exactly one error is mathematically represented as
[tex]P(X = 1 ) = \frac{\lambda ^1 * e^{-\lambda}}{1!}[/tex]
=> [tex]P(X = 1 ) = \frac{0.1054 ^1 * e^{-0.1054 }}{1!}[/tex]
=> [tex]P(X = 1 ) = 0.0948[/tex]
There are 17 rows of seats in a cinema. There are 22 seats in each row. A film was shown in the cinema on friday night. Each ticket for the film cost £7.50
The sale of tickets for that night made £2587.50
How many tickets were not sold
Answer:
29
Step-by-step explanation:
345 tickets = 345 x 7.50 = £2587.5 this means 345 - 374 = 29
how to get 374:
17 x 22 = 374
29 tickets were not sold.
Given that,
There are 17 rows of seats in a cinema.
There are 22 seats in each row.
Each ticket for the film cost £7.50
The sale of tickets for that night made £2587.50
How many tickets were not sold?
According to the question,
There are 17 rows of seats in a cinema.
There are 22 seats in each row.
Each ticket for the film cost £7.50
The sale of tickets for that night made £2587.50
Then,
Total number of seats is,
= 17 x 22 = 374
Number of tickets sold = £2587.50 / £7.50 = 345
Therefore,
45 people filled 345 seats
Unoccupied seats = 374 - 345 = 29
Therefore, 29 tickets were not sold.

(07.01 MC) (Independent Probability) The number of chips of different colors in Amy's bag is shown below:Compund Probability 8 blue chips 9 pink chips 1 black chip Amy takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Amy takes out a pink chip in both draws? (5 points) Group of answer choices 9 over 18 plus 8 over 17 equals 297 over 306 9 over 18 multiplied by 8 over 17 equals 72 over 306 9 over 18 plus 9 over 18 equals 18 over 18 9 over 18 multiplied by 9 over 18 equals 81 over 324
Answer:
The correct option is:
"9 over 18 multiplied by 9 over 18 equals 81 over 324"
Step-by-step explanation:
The number of chips of different colors in Amy's bag is:
Blue (B): 8
Pink (P): 9
Black (Bk): 1
TOTAL (N): 18
It is provided that Amy selects two chips from the bag with replacement.
Compute the probability that Amy takes out a pink chip in both draws as follows:
P (2 Pink Chips) = P (1st Pink Chip) × P (2nd Pink Chip)
= P (P) × P (P)
= [P (P)]²
[tex]=[\frac{9}{18}]^{2}\\\\=(0.50)^{2}\\\\=0.25[/tex]
Thus, the probability that Amy takes out a pink chip in both draws is 0.25.
The correct option is:
"9 over 18 multiplied by 9 over 18 equals 81 over 324"

The product of a number and negative three is twenty-seven. Which of the following could represent this statement?
A. -3n + 27
B. -3(27) = n
C. -3n = 27
D. -3 = 27n
Answer:
C
Step-by-step explanation:
If that's wrong it's D
Answer:
C.
Step-by-step explanation:
If it is a product, that is a way to say that it is multiplication. Since the product is 27, the answer is 27. So what multiplied by -3 equals to 27? To write this, you have to multiply -3 by n to get 27.

In a sample of 63 cans, the average diameter was found to be 3.7in. with a standard deviation of 0.32. Give a point estimate for the population variance of the diameter of the cans
Answer:
0.32
Step-by-step explanation:
Given that:
The sample size of the population = 63
The sample mean = 3.7
The sample standard deviation = 0.32
Thus, the point estimate for the population variance of the diameter of the cans is said to be the standard deviation of the population = 0.32
Suppose the variance (S²) is given as 0.32
Then the standard deviation will be [tex]\sqrt{S^2}[/tex]
=[tex]\sqrt{0.32}[/tex]
= 0.57
Then, since the sample standard deviation is the point estimate, we would have had 0.57 as the answer.

What are polynominal function? Can you please explain in a easy way to understand thank you
Answer:
A polynomial function is a relationship that provides a value that is determined by a polynomial for each input value.
Explanation:
A polynomial is a mathematical expression constructed with constants and variables using the four operations:
Polynomial Example Degree
Constant 1 0
Linear 2x+1 1
Quadratic 3x2+2x+1 2
Cubic 4x3+3x2+2x+1 3
Quartic 5x4+4x3+3x2+2 x+1 4
In other words, we have been calculating with various polynomials all along. When two polynomials are divided it is called a rational expression.
In such cases you must be careful that the denominator does not equal zero. Division by zero is not defined and thus x may not have a value that allows the denominator to become zero. Otherwise, any other value may be substituted for x.
Example
x3−x6−x
x must not have the value of 6 since 6-6=0.
What is the additive inverse of the polynomial –9xy2 + 6x2y – 5x3?
–9xy2 – 6x2y + 5x3
–9xy2 – 6x2y – 5x3
9xy2 + 6x2y + 5x3
9xy2 – 6x2y + 5x3
Answer:
it is the last one (D)
Step-by-step explanation:
The additive inverse of the polynomial; –9xy² + 6x²y – 5x³ is; 9xy² -6x²y +5x³; Choice D
What is additive inverse?The additive inverse of a mathematical term can be evaluated by simply multiplying the term by -1.
Hence, for the given polynomial; –9xy² + 6x²y – 5x³.
The additive inverse is; -1 × (–9xy² + 6x²y – 5x³)
The additive inverse of the polynomial is therefore; 9xy² -6x²y +5x³
