Read the excerpt from Dr. Martin Luther King’s “Letter from Birmingham Jail.” Frankly, I have yet to engage in a direct action campaign that was "well timed" in the view of those who have not suffered unduly from the disease of segregation.

What is the author’s purpose for including this sentence?
to establish the suffering experienced under segregation
to define the concept of a direct action campaign
to criticize the public officials who endorse segregation
to explain his unwillingness to postpone his efforts

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
