A random sample of 206 convicts arrested for violent crimes committed in urban
areas had a 66 percent rate of recidivism. Of those, 25 percent had participated in
rehabilitation programs. A similar sample of 131 convicts arrested for violent crimes
committed in rural areas had a 73 percent rate of recidivism with only 20 percent
reporting participation in rehabilitation programs. With alpha errors limited to .05,
determine if the rate of recidivism is significantly higher in rural areas, and if
participation in rehabilitation programs has any effect.
Urban Areas
Convicts = 206(N1)
Recidivism = 66%(P:1)
Rural Areas
Convicts = 131(N2)
Recidivism = 73%{P-2)
Step 1
Step 2

but which class are u may know that first

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)

a ≈ 172.05
