Are there any answer choices?
Area = x4 + 4x3 + 3x2 - 4x - 4
Length = x3 +5x2 + 8x + 4
Width = Area / Length.
Performing long division with polynomial.
x4 + 4x3 + 3x2 - 4x - 4 / x3 + 5x2 + 8x + 4 = x-1
Width = x-1
Answer:
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
On the problem minus 5x to the -7 so you'll just have 12= -12x and the answer is x=-1
