Since the question is asking for the relative frequencies of the columns, we assume each row must add to 1.00. Divide the numbers in each row by the total of that row.
.. group 1, column A = 102/(102 +34) = 0.75
.. group 1, column B = 34/(102 +34) = 0.25

.. group 2, column A = 18/(18 +14) ≈ 0.56
.. group 2, column B = 14/(18 +14) ≈ 0.44

Consider the line y = x – 4. A line parallel to the graph of the line would have a slope of . A line perpendicular to the graph

kotykmax [81]

Answer:

A. 1

B. $-1$ .

Step-by-step explanation:

We have been given an equation of a line $y=x-4$ .

A. We know that slope of parallel lines is always equal,

We can see that slope of our given line is 1, therefore the slope of the line parallel to our given line would be 1.

B. We know that the product of slopes of two perpendicular lines is $-1$ .

Let m represent slope of perpendicular to our given line, then:

$m\times 1=-1$

$m=-1$

Therefore the slope of the line perpendicular to our given line would be $-1$ .
