<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
Answer:
Option (2)
Step-by-step explanation:
By applying tangent rule in the given right triangle,
tan(42°) = 
tan(42°) = 
Width = 
Width = 6.67
Therefore, width of the given triangle is 6.67 units.
Option (2) is the correct option.
4-2(1)=
4-2=2
So basically the answer is 2
Line d and c are bother parallel but the three options would be them
9*4.25= 38.25 square inches.
