Group i nesting boxes were well separated from each other and well hidden by available brush. there were a total of 480 eggs in group i, of which a field count showed about 275 hatched. group ii nesting boxes were placed in highly visible locations and grouped closely together. there were a total of 874 eggs in group ii boxes, of which a field count showed about 272 hatched. find a point estimate for , the proportion of eggs that hatch in group i nest box placements.

55 / 96 is the proportion of total number of eggs which are hatched.

Step-by-step explanation:

Here, There were a total of 480 eggs in group i, of which a field count showed about 275 hatched.

And, group ii nesting boxes were placed in highly visible locations and grouped closely together. there were a total of 874 eggs in group ii boxes, of which a field count showed about 272 hatched.

Therefore, Total number of Eggs in group i = 480

The eggs in group i which are hatched =  275

Thus, The proportion of eggs in group i which are hatched = Total number of hatched eggs in group i/ Total eggs in group i

= 275/480= 55/96

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:
