Answer:

Step-by-step explanation:

The question is asking you to evaluate -4.5b, which is a simplified way of saying

-4.5 * b

Since we know that b = -4, we can insert that instead of b.

-4.5 * -4

The two negatives cancel each other out, so you're left with

4.5 * 4 = 18

What is the difference between divergence and convergence testing outliers?

LuckyWell [14K]

A divergence testing just diverts your mind and imagination into several possibilities and scenarios regarding the same issue.
A divergence test will simply test your imagination and forces your mind to go into as many directions as possible.

On the other hand, a converge test will sort of converge your imagination and your mind into a set of possibilities or options.
A convergence test will let you sort between a set of possibilities and decide on the best one.
