The mean of the answer is 20.5 because you add all of the number together and divide by 6 because there's 6 numbers.
I'm sorry, but I don't know how to do the standard deviation...
Hope this helped!
To find the total cost, you need to add these numbers together
![1.89 + 3.19 + 2.29 = 7.37](https://tex.z-dn.net/?f=1.89%20%2B%203.19%20%2B%202.29%20%3D%207.37)
you get 7.37 as your answer, but you need to round this to the nearest whole number.
rounding 7.37 will make it 7.
the total cost is about $7
The length would be 18 inches and the width would be 9 inches since the length is twice its width and to find perimeter you do length x 2 and width x 2 and add it together so 18x2 = 36 and 9x2 = 18. 36 + 18 = 54
Answer:
$ 63
Step-by-step explanation:
All you have to do is see what point of the line falls right above 7, and then see what number corresponds to that point.
