Marley tosses a paper cup 30 times and observes
how it lands. after 30 trials, the paper cup lands
open-end up 2 times, open-end down 3 times, and
on its side 25 times. which of the following are the
experimental probabilities of the events based on
marley's observations?
a. p(open-end up) = 1; plopen-end down) = to
p(side)
6. p(open-end up) = 3: popen-end down) = ž
p(side) = 1
c. plopen-end up) = z; plopen-end down) =
d. plopen-end up) = só i plopen-end down) = ;
p(side) =
p(side) = 1

sorry, i'm new here and i'm just trying to figure this out. try quizlet. rate 5* you!

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)

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
