Suppose a box contains 10 defective batteries and 14 good batteries. If 2 batteries are drawn from the box without replacement, what is the probability that the following will occur? (Enter your probabilities as fractions.) (a) the first one is good and the second one is defective (b) the first one is defective and the second one is good (c) one of the batteries drawn is good and one of them is defective

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

If (x-2) 2= 49, then x could be a. -9 b. -7 c.- 2 d. 5 e.9

Can some one me with these questions
