Jk=8x+6
J=(8x+6)/k

kL=6x+20
L=(6x+20)/k

JL=(8x+6)/k * (6x+20)/k

An author receives a contract from a publisher, according to which she is to be paid a fixed sum of $20,000 plus $3.50 for each
Schach [20]

Answer:

The mean of the total payments she will receive is $79,500.

The standard deviation  of the total payments she will receive is $14,000.

Step-by-step explanation:

Given : An author receives a contract from a publisher, according to which she is to be paid a fixed sum of $20,000 plus $3.50 for each copy of her book sold. The author judges that her uncertainty about total sales of the book can be represented by a random variable with a mean of 17,000 and a standard deviation of 4,000 books.

To find : The mean and standard deviation of the total payments she will receive ?

Solution :

Let 'x' represent total sales of the book.

Let 'y' represent the payment to the author.

According to question,

The mean of the total payments she will receive is given by,

\mu_y=20,000+3.50\mu_x

Where, \mu_x=17,000

Substitute in the equation,

\mu_y=20000+3.50\times 17000

\mu_y=20000+59500

\mu_y=79500

The mean of the total payments she will receive is $79,500.

The standard deviation of the total payments she will receive is given by,

\sigma_y=|3.50|\sigma_x

Where, \sigma_x=4,000

Substitute in the equation,

\sigma_y=|3.50|\times 4000

\sigma_y=14000

The standard deviation  of the total payments she will receive is $14,000.

Which of the following best describes the relationship between (x-2) and the polynomial 2x^3+x^2-3
pantera1 [17]
If (x - 2) is a factor of 2x³ + x² - 3 then for the value of x = 2 the polynominal is equal zero.
Substitute:
2 · 2³ + 2² - 3 = 2 · 8 + 4 - 3 = 16 + 4 - 3 = 17 ≠ 0
Answer: B) (x - 2) is not a factor.
