Suppose the line of best fit is being found for some data points that have an r-value of 0.769. if the standard deviation of the x-coordinates is 8.511, and the standard deviation of the y-coordinates is 5.508, what is the slope of the line to three decimal places? a.2.009  b.1.188c.0.498  d.0.842

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:

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
