Answer: 0.8
The volume is 8/45 so a•b•c=8/45
So 2/3•1/3•a=8/45
Multiply 2/3•1/3=0.222222 or 2/9
So 2/9•a=8/45
Divide 8/45 / 2/9= 0.8
a=0.8
Hope this makes sense and it helps!!
The answer that i got is a
Answer:
See Below
Step-by-step explanation:
Isolate f
h = 4 + f
-4 -4
h - 4 = f
Or f = h-4
Answer:
Step-by-step explanation:
If repeated sample sizes of large sizes are taken at random, and proportion P is calculated for samples the sample mean will have a normal distribution irrespective of the original distribution.
In other words, the sample proportion will follow a normal distribution with mean = p-hat and std deviation =
This is a direct corrollary of central limit theorem for sample means.
Hence we have irrespective of sample size, sample proportion will have expected value same as p-hat.
So whether sample size is 500 or 100 the p hat will have the same distribution.
