So you have 318/2580 (since the top is the amount of money they use for food and the bottom is the total). You will want to divide it into 2 so 318/2 and 2580/2. Then you will get 159/1290. The divide 159/1290 with 3. So you will get 52/430. It may seem that you will need to divide 430 with 52 now. Once you get that, you will get the decimal 0.123255814. (I used a calculator). Then Move the decimal twice to the right to make that whole percentage. You will get 12 as you whole number (Ignoring the fact you have 3255814 as your remaining.). So the answer for that is….
12%!!
I dont know man i just have this app to get answers NEXT CALLER
500 (2^(t/12)) = 800 , where t is in hours
2^(t/12) = 1.6
take logs of both sides, and use the rules of logs
t/12 log2 = log 1.6
t/12 = log 1.6/log 2
t = 12(log 1.6/log 2)
= appr 8.1 hours
(btw not sure about this)
Answer:
Step-by-step explanation:
Estimation, 11. ... State the mean and variance of the sampling distribution of the mean ... distribution of the mean is the population variance divided by N, the sample ... (optional) This expression can be derived very easily from the variance sum ... The standard error is represented by a σ because it is a standard deviation.
