to 
Step-by-step explanation:
Given :The owner of a restaurant is reviewing customer complaints. In a random sample of 227 complaints, 57 complaints were about the slow speed of the service.
To Find :Create a 95% confidence interval for the proportion of complaints that were about the slow speed of the service.
Solution:
n = 227
x = 57
Formula of confidence for proportion: 
to 
z at 95% is 1.96
Substitute the values in the formula :
Confidence for proportion: 
to 
Confidence for proportion: to
Hence 95% confidence interval for the proportion of complaints that were about the slow speed of the service is to
Since Square Roots must be greater than or equal to three, just add three to the square root to make it be greater than or equal to negative 3
Answer:
8 l
Step-by-step explanation:

8000 mm = 8 l
Answer:
231q^3
Step-by-step explanation:
Just add them together. They have the same expressions. Whenever you see a number with an ending similarly to another such as 3x and 2x, they can add together.
This is no different. If something is 6x^2 and another is 7x^2, you would add them to get 13x^2.
Hey There! I can help you by explaining how to solve it but not answering sorry! Anyhow, To find the volume of a square based pyramid I suggest you start with the square and do L x W. Than Solve the triangles by using formula 0.5 * b * h. Hint: On the bottom triangle use 8cm from the square with the 3.8cm. Hope you now understand and can find the answer!
