Tisha and her academic team are working to go to state finals. they must have a certain number of points to advance. they have three local matches and will attend a district match. district match points count for four times the number of points than local matches do. choose the equation that would help Tisha find how many points they need to earn in the district match, a, to advance . a=T/4 -b-c-d a=T-b-c-d/4 a=T+b+c+d/4 a=4(T-b-c-d)

Why is studying fractions important

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?
