A pizza baked at 425(degree)F is removed from the oven at 2:00 PM into a room that is a constant 71(degree)F. After 5 minutes, the pizza is at 300(degrees)F. (a) At what time can you begin eating the pizza if you want its temperature to be 130(degree)F?
(b) Using a graphing utility, graph the relation between temperature and time.
(c) Using INTERSECT, determine the time that needs to elapse before the pizza is170(degree) F.
(d) TRACE the function for large values of time. What do you notice about y, the temperature?

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
