Answer:
Step-by-step explanation:
are you in 6th grade what the, well the answer is 35.8
firts lets see how many dollars she has
192 divided by 4 is 48 so she currently has 48 dollars.
and she puts in 2 quarters daily
so lets see how much she need to earn
75 - 48 is 27
lets see how many quarters she need to have 27 dollars 27 x 4 is 180
now lets divide 180 by two because shes giving two everyday. 180 divided by 2 is 54 so if she kept adding two quarters everyday it would take her 54 days to get the rest of the money she need to by and iPod.
i dont know if this helped or not but i solved it

well, lemme help ya with this bruh.... the answer is y > 5/6
hope it's right
Answer:
The probability of getting exactly two read marbles is P = 0,003456%
Step-by-step explanation:
So, each of the following sequences are the desired results(I will use R for a red marble and G for a green marble).
S(1) = R-R-G-G
S(2) = R-G-R-G
S(3) = R-G-G-R
S(4) = G-R-R-G
S(5) = G-R-G-R
S(6) = G-G-R-R
In all, considering there are replacement, there can be 10*10*10*10 = 10000 total sequences, so the probability of getting exactly two read marbles is
P = \frac{P(S(1)) + P(S(2)) + P(S(3)) + P(S(4)) + P(S(5)) + P(S(6))}{10000}
where
P(S(1)) = P(S(2)) = P(S(3)) = P(S(4)) = P(S(5)) = P(S(6)) = (0.4)^{2}*(0.6)^{2} = 0.16*0.36 = 0.0576.
The probability of getting exactly two read marbles is
P = \frac{6*0.0576}{10000} = 0,003456%
