2. let y denote the average starting salary for 2014 u. s. college graduates, measured in dollars. suppose that the average annual salary is $56,000 dollars, with a standard deviation of 8,000. find the mean and standard deviation when salary is measured in thousands of dollars.

Average salary: 56

Standard deviation of the salary: 8

Step-by-step explanation:

$56,000 dollars is 56 thousand dollars.

$8,000 is 8 thousand dollars.

The mean is the average. So the average, measured in thousands of dollars, is 56.

The standard deviation is $8,000. So, the standard deviation measured in thousands of dollars, is 8.

the solution is 12x-6y

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.
