Answer:
A
Step-by-step explanation:
The dispersion refers to the overall spread of the data — how "disperse" it is across values.
The independent variable is what you manipulate in a study, whereas the dependent variable is what you measure.
Central tendency is another word for average.
Answer:
(x+1)(x+2)
Step-by-step explanation:
x^2 + 3x + 2
find what multiples to 2 and adds to 3
Factors of 2 are 1 and 2, 2 + 1 = 3.
so the binomial would be (x+1)(x+2)
and then you would need to do FOIL to check
First: x * x = x^2
Outer: x * 2 = 2x
Inner: x * 1 = x
Last: 1 * 2 = 2
Then simplify: x^2 + 2x + x + 2
x^2 + 3x + 2
Answer:
y ∝ m and 1760 is a constant of proportionality.
Step-by-step explanation:
The relation between a distance in the yards (y) and the same distance in miles (m) is described by the equation y = 1760m.
So, the graph of the above equation passes through the origin(0,0) and it will be a straight line with a constant slope of 1760.
Therefore, a measurement in yards and a measurement in miles are in the relation of proportionality for the same distance.
Hence, y ∝ m and 1760 is a constant of proportionality. (Answer)
