Temperature and air pollution are known to be correlated. We collect data from two laboratories, in Boston and Montreal. Boston makes their measurements of temperature in Fahrenheit, and Montreal in degrees centigrade. Boston measures pollution in particles per cubic yard of air; Montreal uses cubic meters. Both report a correlation of exactly 0.58 between temperature and pollution. Which of the following is true?
A. Boston really has the higher correlation, because Fahrenheit temperatures are higher than Centigrade. B. Montreal really has the higher correlation, because cubic meters are bigger than cubic yards. C. Both cities have the same correlation, because correlation is independent of the units of measurement. D. We do not know which city has the really higher correlation.

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.

Paula makes stained-glass windows and sells them to boutique stores. if her costs total $12,000 per year plus $4 per window for the frame. how many windows must she produce to earn a profit of at least $48,000 in one year if she sells the windows for $28 each? 1. define a variable for the situation. 2. write an inequality that represents her profit. note: revenue is money coming in. cost is money going out. profit is the difference between the revenue and the cost. in other words: revenue - costs profit 3.using words, describe how many windows she must sell to have a profit of at least $48,000.
