Suppose that public opinion in a large city is 55% in favor of increasing taxes to support renewable energy and 45% against such an increase. If an interview of a random sample of 600 people from this city is conducted, what is the approximate probability that more than 360 of these people will be against increasing taxes?
A. 600 choose 360 times 0.55 to the 360 power times 0.45 to the 240 power.
B. Probability of z greater than quantity 0.60 minus 0.45 end quantity over square root quantity of 0.45 times 0.55 over 600 end quantity.
C. Probability of z greater than quantity 0.60 minus 0.55 end quantity over square root quantity of 0.55 times 0.45 over 600 end quantity.
D. Probability of z greater than quantity 0.60 minus 0.45 end quantity over square root quantity of 0.60 times 0.40 over 600 end quantity.
E. 600 choose 360 times 0.45 to the 360 power times 0.55 to the 240 power.

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
