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)

This is the question im stuggling with To study peanut allergies in children, 320 babies who were at high risk for developing peanut allergies were given peanuts. 3.2% of these babies developed peanut allergies. How many babies in the study developed peanut allergies? This is what i did: i cross multiply x with 100 and 3.2 with 320 then divided both sides by 100 to get x=10.24. I dont think its right because to me it doesnt make any sense my question is where did i go wrong? How many babies did not develop peanut allergies?
The following data was collected to explore how the number of square feet in a house, the number of bedrooms, and the age of the house affect the selling price of the house. The dependent variable is the selling price of the house, the first independent variable (x1�1) is the square footage, the second independent variable (x2�2) is the number of bedrooms, and the third independent variable (x3�3) is the age of the house.

A company is researching the effectiveness of a new website design to decrease the time to access a website. Five website users were randomly selected, and their times (in seconds) to access the website with the old and new designs were recorded. To compare the times, they computed new website design time − old website design time. The results are shown here.
