Pick a random card from a deck of cards without jokers, i. e., a 52-card deck. Let A = fcard is an Aceg and R = fcard is redg. Are A and R independent? Now, pick two cards out of the deck sequentially without replacement. Are F = frst card is an Aceg and S = fsecond card is an Aceg independent?

The trigonometric ratios sine and secant are reciprocals of each other

Astore has clearance items that have been marked down by 60%. they are having a sale, advertising an additional 55% off clearance items. what percent of the original price do you end up paying?

Given: ae ≅ ce ; de ≅ be prove: abcd is a parallelogram. we have that ab || dc. by a similar argument used to prove that △aeb ≅ △ced, we can show that △ ≅ △ceb by. so, ∠cad ≅ ∠ by cpctc. therefore, ad || bc by the converse of the theorem. since both pair of opposite sides are parallel, quadrilateral abcd is a parallelogram.
