The scatter plot shows the length of a spring (in inches) when a stretch force (in pounds) is applied. the equation represents the linear model for this data.

y = 0.73x + 1

what does the number 0.73 in the equation mean in this context?

a the spring has no stretch when a force of 0.73 pound is applied.

b the spring will stretch 0.73 inch for every pound of force applied.

c the spring stretches a distance of 1 inch when a force of 0.73 pound is applied.

d the spring stretches at a rate of 0.73 pound per inch.

e the spring has a length of 0.73 inch when no force is applied.

(type an integer or a decimal rounded to three decimal places as needed.) (b) compute the probability that a randomly selected person does not have a birthday on the 1st day of a month. (type an integer or a decimal rounded to three decimal places as needed.) (c) compute the probability that a randomly selected person does not have a birthday on the 30th day of a month. (type an integer or a decimal rounded to three decimal places as needed.) (d) compute the probability that a randomly selected person was not born in january.
