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= 1x + 50.
What is the interpretation of the slope and y-intercept of this equation?
A. The chirping increases as the temperature goes down.
B. The slope predicts a temperature increase of about 1/4• 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°.
C. The slope tells us that for every increase of 1 chirp per minute, we
predict that the temperature increases by 40°. The y-intercept tells
us that when the crickets are not chirping (when x = 0), the
temperature is 0°.
D. The slope predicts a temperature increase of about 4° 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•

Monthly water bills for a city have a mean of $108.43 and a standard deviation of $32.09. find the probability that a randomly selected bill will have an amount greater than $155, which the city believes might indicate that someone is wasting water. would a bill that size be considered unusual?
