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
Answer:
yes it is correct
Step-by-step explanation:
option 1
Answer:
slope = -5/1
y-intercept = (0, -34)
Step-by-step explanation:
slope m = change in y ÷ change in x
= (-9 - -4) ÷ (-5 - -6)
= -5 ÷ 1
= -5/1
y = mx + b ⇒ y = -5x + b
substitute one of the points
-4 = (-5 x -6) + b
-4 = 30 + b
b = -34
Therefore, y-intercept = (0, -34)
Answer:
-7
Step-by-step explanation:
To find x, substitute the values and solve.
R = 2x + 9y
It becomes:
2x + 27 = 13
Rearrange and solve
2x = -14
x = -7
Hope this helps
