A data set on money spent on lottery tickets during the past year by households has a lowest value of and a highest value of . Suppose we want to group these data into classes of equal widths. Assuming we take the lower limit of the first class as and the width of each class equal to , what are the class boundaries and class midpoints

Following are the complete solution to the given question:

Step-by-step explanation:

The Lower-limit of the Ist class:

The width of the class interval:

Lower-limit for the next five-class:

Upper-limit for the next five-class:

For point a:

class intervals  

For point b:

Mid-points:

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:
