Ten young adults living in California rated the taste of a newly developed sushi pizza, topped with tuna, rice, and kelp, on a scale of 1 to 50, with 1 indicating they did not like the taste and 50 that they did. The ratings were: 34 39 40 46 33 31 34 14 15 45 In a parallel study, 10 young adults in Iowa rated the taste of the same pizza. The ratings were: 28 25 35 16 25 29 24 26 17 20 As a market researcher, compare the potential for sushi pizza in the two markets.

step-by-step explanation:

it has to have an angle of 90 degrees

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)
