Use coordinate notation to enter the rule that maps each preimage to its image. Then identify the transformation and confirm that it preserves length and angle measure.
D(-4,5) ► D'(4,-5)
E (1,5) → E'(-1,-5)
F(-4,2) ► F'(4,-2)
The transformation is a rotation of ? V° about the origin given by the rule: (x, y) →

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?

Ineed big ! the cost of a school banquet is $25 plus $15 for each person attending. create a table, sketch the graph, and write an equation in slope-intercept and point-slope form that gives total cost as a function of the number of people attending. what is the cost for 77 people?
