-3(m - 2n - 4) = -9

m - 2n - 4 = -9/-3

m - 2n - 4 = 3

m - 2n = 7

Answer:

m - 2n = 7

Step-by-step explanation:

-3(m -2n - 4) = -9

Divide both sides by (-3)

m - 2n - 4 = (-9)/(-3)

m - 2n - 4 = 3

Add 4 to both sides.

m - 2n - 4 + 4 = 3 + 4

m - 2n = 7

What is the maximum value that a marginal relative frequency can be? Explain.

mart [117]

The maximum value it can be would be 100%. The only times that it could be this high is when there is only a class on the frequency distribution table. Another way, is that there is only one column variable on the table (& or if there is only one row.) Any other time is will be less, but the maximum stays 100%.
