After some training, one of the typists was told that the speed he attained had a resid-
ual of 4.3 words per minute. How should he interpret
this?
A) He types slower than the model predicted, given the
amount of time he spent training.
B) He types faster than the model predicted, given the
amount of time he spent training.
C) He can't interpret his residual without also knowing
the correlation.
D) He can't interpret his residual without also knowing
the size of other people's residuals.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
