Consider these three numbers expressed in scientific notation: 2.4 × 10^4, 6.3 × 10^5, and 9.6 × 10^7. which number is the greatest, and by how many times is it greater than the smallest number? a)the greatest number is 9.6 × 10^7. it is 400 times greater than the smallest number. b) the greatest number is 6.3 × 10^5. it is 40 times greater than the smallest number. c)the greatest number is 6.3 × 10^5. it is 400 times greater than the smallest number. d)the greatest number is 9.6 × 10^7. it is 4,000 times greater than the smallest number.

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.
