In an annual charity drive, 35% of a population of 560 make contributions. If, in a statis-tical survey, 15 people are selected at random and without replacement, what is the probabilitythat at least two persons have contributed?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

i think the length is 12 and the width is 17
