Answer:

See explanation

Step-by-step explanation:

Consider the natural number $n(n+1)(n+2).$

If $n$ is the natural number, then $n+1, \ n+2$ are next two natural numbers, so numbers $n,\ n+1$ and $n+2$ are three consecutive numbers.

Given three consecutive natural numbers, one of them is always even number and one of them is always multiple of 3, so the product

$n(n+1)(n+2)$

is divisible by 6.

Answer: A confidence interval for the mean cost (in dollars) for one shipment of vases = (49,59)

Step-by-step explanation:

Confidence interval for mean: Mean ± Margin of error

Given: The online store found the mean wholesale cost of one shipment of vases was ĉ = 54 dollars, with a margin of error of 5 dollars.

A confidence interval for the mean cost (in dollars) for one shipment of vases

$=(54-5, 54+5)\\\\=(49,59)$

Hence, a confidence interval for the mean cost (in dollars) for one shipment of vases = (49,59)

The registration for new members of a gym is $ 1.
The gym payment per day is $ 1.
The equation that models this problem is:
y = x + 1
Where,
x: is the number of training days
y: it is the total payment
The intersection with the y axis (1) represents the cost of the inscription.
The slope of the line (1) represents the daily payment.
