- Carl Catcher has a batting average of .370, meaning that he makes a hit 37% of the times he is up at bat. Pete Pitcher has a batting averager of only .110. Let x be the number of times Carol comes up to bat and let y be the number of times Pete comes to bat. a. If Carl bats 7 times and Pete bats 3 times, what should ther overall batting average be? b. If a total of 50 times at bat, how many times may Pete bat in order for their combined average to be as close as possible to .300? (define 3 variables, write system and solve)It asks for number of even outcomes. Is it: a. 3 b. 3/6 or 1/2Solve the problem. At the Jumping Jack cookie factory, quality assurance inspectors remove broken or otherwise defective cookies from a moving conveyor belt prior to packaging. Based on past studies, the plant manager knows that the inspectors eliminate 98% of the defective cookies at a conveyor belt speed of 9 feet per minute. As the belt speed increases, the factory can produce more cookies per hour, but at the cost of lower quality of the packaged product. Inspectors collect only 60% of defective cookies at a belt speed of 18 feet per minute.

- n: n(102) = 10 C8In a survey of consumers, approximately 43% said they would be willing to pay $1500 more for a new car if the car had an EPA rating of 83 miles per gallon. If your car currently gets 21 miles per gallon and you drive approximately 10,000 miles per year, in how many months would your savings on gasoline pay for the increased cost of such a car? Assume that the average cost of gasoline is $2.00 per gallon. Round to the nearest whole number.When rolling a number cube, labeled 1 through 6,P(4) is twice as likely to occur as P (2).
