It is often convenient to use the axis intercepts as points for graphing a line.
Here, y=0 when x=-16.
.. y = 8 when x = 0.
Answer:
Step-by-step explanation:
Domain is all possible x- values- since the dots are solid, you include them in the domain-
the lowest X possible is at -11 and the highest is +11
it s a continuous graph, so it will include any and all number between the two ends
Answer:
C) At the 95% confidence level, the estimate of 0.48 is within 0.02 of the true proportion of county residents in favor of larger school zones in that county.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
95% CI between 0.48 - 0.02 = 0.46 and 0.48+0.02 = 0.5.
The interpretation is that we are 95% sure that the true population proportion is in this interval, that is, with 95% confidence, the estimate is within 0.02 of the true proportion, and so the correct answer is given by option C.
