Answer:
the degree to which the sample varies from the population on important characteristics.
Step-by-step explanation:
Maximum variation sampling is a sampling method in which the sample is made up of extremes. The sample is usually chosen in such a way that reflects a wide degree of diversity in a population.
Maximum variation sampling is used;
When the purpose is to understand the view of diverse groups of people on a particular topic.
When the researcher doesn't know much about the population
When the researcher wants the responses to be as diverse as possible.
Answer:
x = 12
Step-by-step explanation:
81 + 57 + 2x + 18 = 180
156 + 2x = 180
2x = 24
x = 12
Based on the calculations, the coordinates of the y-intercept are (0, -9).
<h3>What is the y-intercept?</h3>
In Mathematics, the y-intercept of any graph (parabola) occurs at the point where the value of "x" is equal to zero (0). Similarly, the x-intercept refers to the point at which the graph of a function crosses the x-axis and the value of "y" is equal to zero (0).
<h3>How to calculate the slope of a line?</h3>
Mathematically, the slope of any straight line can be calculated by using this formula;
Substituting the given parameters into the formula, we have;
Slope, m = (-4.5 - 3)/(-3 + 8)
Slope, m = -7.5/5
Slope, m = -1.5.
Mathematically, the standard form of the equation of a straight line is given by;
y - y₁ = m(x - x₁)
At point (-8, 3), we have:
y - 3 = -1.5(x + 8)
y - 3 = -1.5x - 12
y = -1.5x - 12 + 3
y = -1.5x - 9
Therefore, the coordinates of the y-intercept are (0, -9).
