Use each student’s quiz score to answer the questions. annika’s quiz scores 60%, 75%, 78%, 80%, 85%, 85%, 90% josiah’s quiz scores 62%, 65%, 68%, 79%, 83%, 90%, 92% annika has a mean that is josiah’s mean. josiah’s median is annika’s median. the range is . who has the lowest interquartile range?

you would need to also lose 1 point for each of the other outcomes for it to be fair.

step-by-step explanation:

60 for the first and 130 for the second

well kind of. you get friend requests. and you can accept them or not so yes.

step-by-step explanation:

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)
