What is the surface area of a triangular prism?

The surface area is

Step-by-step explanation:

we know that

The surface area of the triangular prism is equal to

where

B is the area of the triangular base

P is the perimeter of the triangular base

L is the length of the prism

Find the area of the base B

Find the perimeter of the base P

we have

substitute in the formula

And replacing we got:

And the best option would be:

d) -2.5

Step-by-step explanation:

For this problem we know that the true mean of  trash every day is:

And from the info given we also know that:

represent the sample mean

sample size selected

the population standard deviation assumed

If we want to find the z score for the person we can use the following formula:

And replacing we got:

And the best option would be:
