What is the domain of this function? A. {3, 9, 12} B. {-2, 2, 3, 4} C. {-2, 2, 3, 4, 9, 12} D. {3}
Fynjy0 [20]
B. {-2, 2, 3, 4}
usually in a graph like this, the domain (x) is on the left side, and the range (y) is on the right side.
hope this helps! ❤ from peachimin
Answer:
The selections are dependent.
Yes, they can be treated as independent (less than 5% of the population).
Step-by-step explanation:
Since the selections are made without replacement, each selection affects the outcome of the next selection and, therefore, the selections are dependent.
Although they are dependent, the selections can be treated as independent if the sample size is no more than 5% of the total population. In this case, the sample size is 1235 adults out of a population of 15,958,866 adults. The percentage represented by the sample is:
Thus the selections can be treated as independent for the purposes of calculations.
It's m=y2-y1/x2-x1
This is the formula you need to use to find the slope of a line
Answer:
First we find the y intercept which is 1 y = mx + b m is slope b is y intercept
y = mx + 1
slope is 2
y = 2x + 1
Step-by-step explanation:
Answer:
a. always
Step-by-step explanation:
In a simple linear regression, the slope measures the steepness of the linear relationship between the two variables, it ranges from (-∞ to +∞ ) while the correlation coefficient measures the tightness of the linear relationship between the two variables, it ranges from (-1 to +1 ).
So the correlation coefficient and the slope will always have the same sign though their values might differ.
