CORRECT ANSWER ONLY PLEASE A new drug claims to reduce the number of migraines an individual suffers. In a study on the effectiveness of the new drug, 50 subjects were given the new drug and another 50 subjects were given a placebo.

At the end of the 6-month study, the group given the new drug reported an average of 1.3 migraines a week. The group given the placebo reported an average of 2.5 migraines a week.

The data from the study are rerandomized 10 times. The difference of the means from rerandomization are

1.2, 3.4, 1.8, 1.3, 1.1, 0.9, 2.5, 0.7, 1.1, and 0.9.

What is the most appropriate conclusion about the new drug to draw from this information?

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)

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
