Arnold has recorded the number of chirps per minute (x) that crickets make at different temperatures (y) .
He has determined that the association is linear and that the line of best fit is y = 1/4x + 50.
What is the interpretation of the slope and y-intercept of this equation?
A) The slope predicts a temperature increase of about 4 degrees for every increase of 50 chirps per minute. The y-intercept shows that when the crickets are not chirping
(x = 0), the temperature is 1/4 degrees.
B) The chirping increases as the temperature goes down.
C) The slope tells us that for every increase of 1 chirp per minute, we predict that the temperature increases by 40 degrees. The y-intercept tells us that when the crickets are not chirping ( when x = 0 ), the temperature is 0 degrees.
D) The slope predicts a temperature increase of about 1/4 degrees for every increase of 1 chirp per minute. The y-intercept shows that when the crickets are not chirping
(x = 0), the temperature is 50 degrees.

Question part points submissions used suppose that 100 lottery tickets are given out in sequence to the first 100 guests to arrive at a party. of these 100 tickets, only 12 are winning tickets. the generalized pigeonhole principle guarantees that there must be a streak of at least l losing tickets in a row. find l.
