Explanation:
Regardless of the number of factors, the product will be negative if an odd number of factors are negative.
In the example, 3 of the factors are negative. 3 is an odd number so the product will be negative.
-2*-3*-1*1 = -6
_____
Of course, the product will be zero if any factor is zero, regardless of the signs of any other factors.
Answer:
Sampling is necessary because researchers in the social sciences almost never have enough resources — time or money — to collect information about the entire set of subjects of interest to them.
Step-by-step explanation:
Sampling is done because you usually cannot gather data from the entire population. Even in relatively small populations, the data may be needed urgently, and including everyone in the population in your data collection may take too long.
Y = - 10x has a negative slope, m = -10, and a y-intercept of (0, 0).
The graph includes the following points:
{(-2, 20), (-1, 10), (0, 0), (1, -10), (2, -20)}.
Attached is a screenshot of the graph, where it includes the y-intercept crossing along the point of origin, (0, 0).
