landscaped shopping center. The mulch is being pumped into the truck. After 30
minutes, the truck is 75% full and weighs 33 tons. Fifteen minutes later, Rosa’s
truck is fully loaded and weighs 42 tons. If Rosa’s truck weighs 15 tons when it is
empty, what was the rate in tons per minute that the mulch pump took to load the
truck?

What is the correlation and causation for the data set?
Ite
A. There is a strong positive correlation between the price of bread and the price of
milk. There is a likely cause-and-effect relationship because shoppers often buy both
bread and milk at the same time.
B. There is very weak positive correlation between the price of bread and the price
of milk. There is a likely cause-and-effect relationship because shoppers often buy
d
both bread and milk at the same time.
