Jose worked 2.5 hours more than william. together, they worked a total of 22 hours.. william workwd n hours.. a) h+5=22, b) h +(h+2.5)=22 c)h+(h-32.5)=22 d) h+2.4=22

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (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?

Consider the diagram. lines e and c can be described as
