If
f(x) = \x-3
and g(x) = 1 – x2, then what
do you notice about the domain of (fog)(x) ?

What basic trigonometric identity would you use to verify that csc x sec x cot x = csc^(2)x

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?

Which number line correctly shows 0.8 + 0.3?
