Angles/267623: if the measure of an angle is 2x and the measure of its complement is x what is the value of x? 1 solutions Answer 196336 by stanbon(57307)   on 2010-02-09 14:13:21 (Show Source): You can put this solution on YOUR website! if the measure of an angle is 2x and the measure of its complement is x what is the value of x? --- an angle and its complement add up to 90 degrees. 2x + x = 90 3x = 90 x = 30 ============ Cheers, Stan H.

Angles/267625: True or False two angles are supplementary. if one angle has a measure twice the other angle what are the measures of the angles? -- supplementary means they add up to 180 1 solutions Answer 196335 by stanbon(57307)   on 2010-02-09 14:09:29 (Show Source): You can put this solution on YOUR website! That is not a true or false question. Cheers, Stan H.

Probability-and-statistics/267588: A box contains 30 balls: 20 are red and 10 are blue. Five balls are selected at random, without replacement. What is the probability that four of them are red? What if the five balls are selected at random with replacement (i.e, a selected ball is put back in the box before the next selection is made)? 1 solutions Answer 196334 by stanbon(57307)   on 2010-02-09 14:07:30 (Show Source): You can put this solution on YOUR website! A box contains 30 balls: 20 are red and 10 are blue. Five balls are selected at random, without replacement. What is the probability that four of them are red? P(r = 4) = (20C4*10C1)/30C5 = 4845/27405 = 0.1768 -------------------------------------------------- What if the five balls are selected at random with replacement (i.e, a selected ball is put back in the box before the next selection is made)? P(r = 4) = 5C4(2/3)^4(1/3) = 0.3292 ===================================== Cheers, Stan H.
