This year I'll have 180 hours free during which I can play video games or watch movies. Each movie lasts 2 hours, and I'll be able to play each video game for 20 hours. I have $600; each movie costs $10, and each game costs $40. (a.) If I make 3 new friends every time I get a new video game but still make 1 friend every time I watch a movie, how many movies should I watch this year to maximize the number of new friends I make?

(b.) If I instead make 5 friends every time I get a new video game and 1 friend every time I watch a movie, how many movies should I watch this year to maximize the number of new friends I make?

(c.) Suppose I want to make as many new friends as possible. What is the smallest whole number of new friends each new video must give me in order for it to make sense for me to buy only video games this year?

At wind speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. wind speeds below 1000 cm/sec deposit sand and wind speeds above 1000 cm/sec move sand to new locations. the cyclic nature of wind and moving sand determines the shape and location of large dunes. at a test site, the prevailing direction of the wind did not change noticeably. however, the velocity did change. fifty-nine wind speed readings gave an average velocity of x = 1075 cm/sec. based on long-term experience, σ can be assumed to be 245 cm/sec. (a) find a 95% confidence interval for the population mean wind speed at this site. (round your answers to the nearest whole number.) lower limit cm/sec upper limit cm/sec
