the sum of two numbers is 49.Twice the smaller number is 97 less than 3 times the larger number.What are the numbers. help mee I
kondaur [170]

Answer:

smaller number is 10

larger number is 39

Step-by-step explanation:

a = small number

b = larger number

a + b = 49

2a = 3b - 97

substitute 49-a into second equation for b

2a = 3(49-a) - 97

2a = 147 - 3a - 97

5a = 50

a = 10

b = 39

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.
