Find the domain of the graphed function.
2 answers:
For every point on the curve, imagine drawing a vertical line until that vertical line reaches the x axis.
Doing this will essentially shade the x axis number line from x = -4 to x = 2
The graph shows points in which the x coordinate is as small as -4 or as large as 2, or anything in between
Domain:
Answer: Choice B
note: the domain is the set of allowed inputs or x values

Answer:
193.586 deaths per 100,000
Step-by-step explanation:
The cause-specific mortality rate for a disease in a per 100,000 basis is determined as the total number of deaths due to the disease multiplied by 100,000 and divided by the average (mid-year) total population.
There were 597,689 deaths due to diseases of the heart in a population of 308,745,538 people. The cause-specific mortality rate for diseases of the heart per 100,000 in this population is:
The mortality rate is 193.586 deaths per 100,000.
Answer:
The margin of error for the 99% confidence level for this sample is ±2.23.
None of the given figures is close to the answer:
E. None of the above
Step-by-step explanation:
margin of error (ME) around the mean can be calculated using the formula
ME= where
- z is the corresponding statistic of the 99% confidence level (2.576)
- s is the population IQ standard deviation (15)
- N is the sample size (300)
Using these numbers we get:
ME= ≈ 2.23
