Scientists are studying the temperature on a distant planet. let y represent the temperature (in degrees celsius).
let x represent the height above the surface (in kilometers). suppose that x and y are related by the equation =y−235x .
answer the questions below. note that a change can be an increase or a decrease.

for an increase, use a positive number. for a decrease, use a negative number.

what is the temperature change for each kilometer we go up from the surface?

Max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

What is the distance between the points (2, 5) and (5,9)?
