Acafeteria worker is wondering how student lunch prices at a high school have changed over time. she researches lunch prices for the years 2000-
through 2015 and plots the data in a scatter plot. the best-fit line for the data has the equation y = 0.057 x + 1.150, where x is the number of years
since 2000 and y is the student lunch price, in dollars.
determine whether each statement below is true or false based on the equation of the line of best fit. select true or false for each statement
true false
the student lunch price was generally increasing between 2000 and 2015.
the student lunch price changed by approximately 5.7 cents per year.
the student lunch price in 2015 was approximately $1.15.

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry. how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
