Mariah has a spinner that has 10 equal sections, each containing a different number from 1 to 10. mariah determines about how many times the spinner will land on a number that is greater than 7 in 250 spins, and her work is shown below. p(number greater than 7)= numbers greater than 7/ total number of sections times number of spins = 4/10 (250) = 100 what mistake did mariah make, if any?

1. an economy consists of three workers: larry, moe, and curly. each works 10 hours a day and can produce two services: mowing lawns and washing cars. in an hour, larry can either mow one lawn or wash one car; moe can either mow one lawn or wash two cars; and curly can either mow two lawns or wash one car. a. calculate how much of each service is produced under the following circumstances: a. all three spend all their time mowing lawns. b. all three spend all their time washing cars. c. all three spend half their time on each activity d. larry spends half of his time on each activity, while moe only washes cars and curly only mows lawns b. using your answers to part a, draw a production possibilities frontier and label points a, b, c, and d on your graph. explain why the production possibilities frontier has the shape it does. c. are any of the allocations calculated in part a inefficient? explain.
