My name is Ann [436]

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

A college bookstore charges $60 for a yearly membership. The first book is free with membership and any book after that costs $7

brilliants [131]

Answer:

The equation representing Total money spend being as a member is $m = 60+7.6(b-1)$

Step-by-step explanation:

Given:

Memberships charges = $60

Cost of 1 book = $7.60

Let number of books be 'b'.

We need to find Total money 'm' spend yearly on buying books after becoming member.

Now we know that 1 book is free for a member.

Total money spend 'm' will be equal to Sum Memberships charges and Cost of 1 book multiplied by number of books bought yearly minus 1.

Framing in equation form we get;

$m = 60+7.6(b-1)$

Hence The equation representing Total money spend being as a member is $m = 60+7.6(b-1)$
