Answer: (-1,-2) is the vertex point
I think that's what ur asking for
Step-by-step explanation:
Answer:
I would say the best answer choice is B.
C = 18n + 45
441 = 18n + 45
441 - 44 = 18n + 45 - 45
396 = 18n
396/18 = 18n/18
22 = n
Therefore, 22 ft of cabinet is made when the cost is $441
The Z-value for a 90 percent confidence is 1.645
To find the sample size use the formula:
Sample size = Z-value x SD / error)^2
Using the provided information:
SD = 4,000 miles
Error = 500 miles
Sample size = ((1.645) (4000)/ 500)^2 = 173.18 = 174
