Suppose the cost for your glass are as follows: •Region 1 (the area between the square and circle A): $0.10 per square inch
•Region 2 (the area between circle A and circle B): $0.15 per square inch
•Sectors for circle B: One sector will be made from expensive glass that is $0.80 per square inch. The rest of the sectors will be from glass that is $0.20 per square inch.

How much does the glass for region 1 cost?
How much does the glass for region 2 cost?
What is the total cost for the glass for the sectors in circle B?
What is the total cost of the glass for your window?
You have only $100 to spend on glass supplies. Do you have enough money to buy your glass?

In a test for esp (extrasensory perception), the experimenter looks at cards that are hidden from the subject. each card contains either a star, a circle, a wave, a cross or a square.(five shapes) as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. when the esp study described above discovers a subject whose performance appears to be better than guessing, the study continues at greater length. the experimenter looks at many cards bearing one of five shapes (star, square, circle, wave, and cross) in an order determined by random numbers. the subject cannot see the experimenter as he looks at each card in turn, in order to avoid any possible nonverbal clues. the answers of a subject who does not have esp should be independent observations, each with probability 1/5 of success. we record 1000 attempts. which of the following assumptions must be met in order to solve this problem? it's reasonable to assume normality 0.8(1000), 0.2(1000)%30 approximately normal 0.8(1000), 0.2(1000)% 10 approximately normal srs it is reasonable to assume the total number of cards is over 10,000 it is reasonable to assume the total number of cards is over 1000
