Answer:
Step-by-step explanation:
Let be the average of the sample, and the population mean will be
We know that:
gr
Let be the standard deviation and n the sample size, then we know that the standard error of the sample is:
Where
In this case we are looking for:
This is:
or
Now we get the z score
Looking at the tables for the standard nominal distribution we get
Drawing this on a paper, will give you 5280 west, then 2460 north and then straight back to the start.This will give you a triangle. The way to answer this is to first compute the total square footage of the area in problem, then divide by 43,560 which is the square footage in an acre.
So putting this mathematically: 5280 x 2460 = 12988800 (total sq footage in the box) / 2 (cut it in half to get the square footage of the triangle)
= 6494400 (total square footage of triangle) /43560 (square footage in an acre
= 160 acres.
Answer:
Step-by-step explanation:
Area is a 2 dimensional idea. The x and y direction. the top of a box. It covers one side of the box
Surface area is three dimensional. How much wrapping paper you need to cover a present. It is all of the sides of the box
The answer for that is 7/100 but i think they are looking for 1/100
