An insurance company believe that people can be divided into two classes those that are accident prone and those that are not. Their statistics shows that an accident prone person will have an accident at some time within a fixed one year period with probability 0.4, where as this probability decreases to 0.2 for a non accident known person if we assume that 30% of the population is accident prone what is the probability that a new policy holder will have an accident within a year of purchasing a policy.

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)

answer is b chief keef

get this one right

use photo math thats what i use u can scan the problem and it tells u the answer
