eshaal is creating a model of a pyramid. the model created will need to be scaled up from the blueprint.

triangle acb, point d is on segment ac between points a and c, point e is on segment bc between points b and c

if segments de and ab are parallel, which of the following expressions will eshaal determine the length of segment bc?

bc = ce
bc equals ac times ce all over cd
bc equals ac times de all over ce
bc = ac

What are the relative frequencies, to the nearest hundredth, of the rows of the two-way table? group 1: a 15 b 45 group 2: a 20 b 25

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player, each of the 8 songs is played once in random order. find the probability that among the first two songs played (a) you like both of them. would this be unusual?
