Answer:
(19229.11 ,20770.89)
Step-by-step explanation:
We are given the following information:
Sample size, n = 17
Sample mean = 20,000 pounds
Sample standard deviation = 1,500 pounds
Confidence level = 95%
Significance level = 5% = 0.05
95% Confidence interval:
Putting the values, we get,
To solve the problem posed in the statement we need to know the equivalence between squared foot and squared inches, and that is:
1 square foot = 144 square inches
So Reed uses 8 pieces of glass per 144 squared inches as well.
Now we can use a rule of three, simple and direct proportion to solve the question, it goes like this:
144 squared inches ------> 8 pieces glass
864 squared inches ------> x
x = (864)(8)/144
x = 48
Hence, Reed will use 48 pieces of glass to make a window that is 864 square inches.
None of the offered choices is correct.
The radical cannot be simplified. If rewritten, it must be written as something like
![x \sqrt[3]{ \frac{6}{x}}](https://tex.z-dn.net/?f=%20x%20%5Csqrt%5B3%5D%7B%20%5Cfrac%7B6%7D%7Bx%7D%7D%20)
or
In points form the answer is (-8,-4) and in equation form the answer is x=-8, y=-4
