Write an equation in the form of y=mx for the following situation. Then give three ordered pairs associated with the equation for x-values of 0, 5, and 10

x represents the number of gallons of gas sold at $4.93 per gallon, and y represents the total cost of the gasoline (in dollars)

The equation is,

The two square pyramids are similar. find the total volume of both pyramids if the ratio of their surface areas is 9/16

The function models the number of accidents per 50 million miles driven as a function

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?
