Select the correct answer. ♡
A polling company has been hired to determine the approval rating for a local member of Congress. The company completed the poll by
creating a survey and instructing representatives to stand outside a mall to give the survey to departing shoppers. The polling representatives
were also instructed to take responses only from participants who were male. Then, the polling company published a report which put the
congressperson's approval rating at 79%.
Why could this sample be biased?
O A
The survey questions were biased toward the congressperson's opponent.

The representatives of the company only gave the survey to a select group, as opposed to a wider, more representative
sample.

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

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)
