1/4(8-4p) + 2p = 12
Use distributive property by multiplying 1/4 by each term inside parentheses:
2 - p + 2p =12
Combine like terms:
2 + p = 12
Subtract 2 from both sides:
P = 10
Answer:
Step-by-step explanation:
Given that:
The number of observations is:
6, 10, 12
If we are to use a simple random sampling without replacement, then we will have:
(6,10) (6,12) (10,12)
Here;
the sample size n = 2
The population size N = 3
For (6,10) ; The sample mean = 
= 
= 8
For (6,12) ; The sample mean = 
= 
= 9
For (10, 12) ; The sample mean = 
= 
= 11
The probability distribution of sample mean(x) is:
X 8 9 11
P(X=x) 
Thus, the probability that the sample mean is larger than 8 is:
P(X> 8) = P(X = 9) + P(X + 11)
P(X> 8) = 
P(X > 8) = 
P(X> 8) =

Hope this helps!!! :)
Step-by-step explanation:
#1: if there is buy 1 get 1 free, then buy 6 get 3 free. so 2.8 times 3 = $8.4
#2: 4 for $3. break it up to 1 for $0.75. now 0.75 times 6 = $4.5
#3: the second one. $4.5 < $8.4
#4: 45 times 12 = $54
Answer:
a - (6-9)

Step-by-step explanation:
Saving money is essential to living life. Everything costs money. Even this wifi? Not free. The device you asked this on? Not free. Saving money is important but why won't people do it? They think its hard, but it's actually easy. Step one, save one cent today, two cents tomorrow, three cents the next day...etc. That leaves you with 365 in the bank if I did the calculations right. Another way you can save is by setting a budget. Pretty easy, but you have to control what you buy and understand that buying this or that could prevent you from buying something else. The last one? Get a job. Preferably a one that gets you a higher pay without actually needing a degree, like a warehouse worker or a waiter.
These methods help you in the best way possible to save money. Good luck!
