Answer: mean of sampling distribution of means = 18.6
Step-by-step explanation:
In sampling theory, the population mean is expected to equal to the mean of sampling distribution of means if the estimator is to be a good representative of the population. so, on this note, the mean of sample distribution of means is equal to the population mean = 18.6
5 because u subtract u do the adding subject
First if a>0 sqrta=a^(1/2), and (a^p)^q=a^pxq
sqrt(a^4/9)= (a^4/9)^1/2=a^4/9x1/2=<span>a^(2/9)
so the answer is </span><span>a^(2/9)</span>
Answer:
d) $7.82
Step-by-step explanation:
just multiply the 2 numbers
C

$12
If the cost c is at least $12 then it could be equal to 12, or could also be a cost greater than $12. So, c is greater than or equal to 12, expressed as <span>c

$12</span>
