The cumulative probability up to z = 0 (the mean) is 0.5000.
The cumulative probability up to z = 1.4 is 0.9192.
Therefore the proportion between the mean and z = 1.40 is:
0.9192 - 0.5000 = 0.4192.
the answer is: 0.4192 or 41.92%.

Which graph or equation represents a Nonpoportional relationship A B C or D

VARVARA [1.3K]

Answer:

Step-by-step explanation:

A graph that represents a proportional relationship usually has the line cutting through the line of origin (0, 0).

The graph in option A does not have the line passing through the point of origin (0, 0), therefore, it does not represent a proportional relationship.

For an equation that represents a proportional relationship, it is written in the form of y = kx

Where, k is the constant of proportionality.

Therefore, the two equations given represents a proportional relationship.
