<span>The mean of the sampling distribution of the mean is the mean of the population from which the scores were sampled. Therefore, if a population has a mean μ then the mean of the sampling distribution μ₁ of the mean is also μ.
So </span>μ = μ1 =82
Now let' calculate σ the standard deviation <span> of the sampling distribution of the mean: It is computed as follows:
</span>σ₁ = σ/√n ==> σ₁ = 6/√n
(x-4)(x+9) because X to the power of 2 +9x+(-4x)-36 =(x-4)(x+9)
Answer:
32^20
Step-by-step explanation:
Here you can either:
Convert to logarthmic format and use base changing formula.
OR
Simply do 2^100=32^x, find x.
I chose option 2 because its quicker here. However, it will not always work.
