:
If

is found to perform a

transformation, what are the coordinates of the transformed triangle?
(0, 0), (-4,0), (0, -5)
(0, 0), (-4,0), (0,5)
(0, 0), (4,0), (0, -5).
0 (0,0), (4,0). (0,5).

Use set builder notation to represent the following set: { -3, -2, -1, 0}

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

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?
