Hello :
the terme general is : an = a1 +(n-1)d
a11 = a1+(11-1)×5
a11 = -12+50
a11 = 38
<span>the sum of the first 11 terms is : S11 = (11/2)(a1+a11)
</span>S11 = (11/2)(-12+38)
S11 = 143

Let "n" be a number
9 + 3n = 57
3n = 57 - 9
3n = 48
n = 48/3
n = 16
Answer:
And then the maximum occurs when , and that is only satisfied if and only if:
Step-by-step explanation:
For this case we have a random sample where where is fixed. And we want to show that the maximum likehood estimator for .
The first step is obtain the probability distribution function for the random variable X. For this case each have the following density function:
The likehood function is given by:
Assuming independence between the random sample, and replacing the density function we have this:
Taking the natural log on btoh sides we got:
Now if we take the derivate respect we will see this:
And then the maximum occurs when , and that is only satisfied if and only if:
Step-by-step explanation:
I think its c cus its more relatable .
