She needs four times as much pig food as cow food and needs half the amount of goat food as pig food. If Ms. DeVoto orders 600 packages of animal food, how much pig food does she buy? Let b represent the number of packages of cow food Ms. DeVoto purchased for the farm.

the probability is 0

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.  

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

6e14 is the answer.
