1-23 latisha's friend brandee forgot to make up a test and had these scores: 80
84%, 0%, and 85%.
hint: 1) before you begin, review the strategy for calculating the average of a set of numbers.
a. calculate brandee's average. does this average score really represent her abilities? why or why not?
b. brandee persuaded her teacher, ms. juarez, to allow her to make up the missed test. brandee received
a 78%. calculate her new average or mean.
c. what difference did the 0% score make? does this new mean represent brandee's ability more
accurately?
guys i really need on a. b. and c. if you could that would be great

idk

step-by-step explanation:

no

explanation:

you can be freinds, and people but not follow people.

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)
