Answer:
Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, a=-b
Step-by-step explanation:
The domain refers to values for which the expression is defined.
This implies that, the denominators are not equal to zero.
Hence the domain is given as,b is such that b is a member of all real numbers,except b=0,a=0, and a=-b

Answer:
The rate of change is the slope
slope = 72/6 = 12
(0, 0) means zero pages have been printed in 0 minutes
(6, 72) means there have been 72 pages printed in 6 minutes
Step-by-step explanation:
The rate of change is the slope
slope = 72/6 = 12
(0, 0) means zero pages have been printed in 0 minutes
(6, 72) means there have been 72 pages printed in 6 minutes
Answer:
135 to 143 minutes.
Step-by-step explanation:
Standard deviation (s) = 22.6 minutes
Sample size (n) = 123
Sample average (X) = 139 minutes
The lower and upper bounds of a confidence interval are given by:
Lower bound:
Upper bound:
For a confidence interval of 95%, the z-score value is 1.96.
Therefore, the 95% confidence interval for the mean surgery time is:
Lower bound:
Upper bound:
The 95% confidence interval is 135 to 143 minutes.
