the mean value of land and buildings per acre from a sample of farms is $1200 with standard deviation of $100.The data has a bell shaped distribution. Using the empircial rule, determaine which of the following farms, whose land and bulidng values per acre are given, are ususal (more than two standard devitations from the mean).Are any of the data values very unsusal (more than three standard deviations form the mean)? $1215 $1409 $1128 $863 $1283 $1035

its d. the first coordintaes are 10,32

step-by-step explanation:

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:

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
