Answer:
(d) μ and σ²/n
Step-by-step explanation:
In a sampling distribution of sample means, the mean is equal to the population mean, which is μ.
The standard deviation of the sampling distribution of sample means is given by
σ/√n.
The variance of a distribution is the square of the standard deviation; this means the variance of the sampling distribution of sample means would be
(σ/√n)² = σ²/(√n)² = σ²/n

I´m positive that is right </span>
Answer:
(3,-2)
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given
Shape: Rectangle
Diagonals: AC and BD
Required
Determine BD
From the question, we understand that the shape is a rectangle and its diagonals are AC and BD
Every rectangle has 2 diagonals, both of which are equal.
This implies that:
Recall that:
Hence,
Wrong person I pay someone to do my math for me :)
