The following two-way contingency table gives the breakdown of 300 randomly selected patrons at a grocery store according to the number of items purchased and whether or not the patron made an impulse purchase at the checkout counter. What is the marginal distribution for Impulse Purchase?

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%

Four thousand nineteen hundred thousandths in standard form is 4900

We know on the regular cosine graph, it decreases from 0 to pi. so, we need to set 0 as y.0 = 4 cos(2x-pi)0 = cos(2x-pi)2x-pi = pix = piwe already know the answer, but do pi on your own!
