In which of these examples, binomial distribution can be used? a) Finding the best month to launch a new product b) Accurately p
irina1246 [14]

Answer: The answer is (d) Accurately predicting who will be promoted at work.


Step-by-step explanation:  We are given four options and asked in which of these four, we can use binomial distribution.

Binomial distribution is used in that experiments where there are only two outcomes, either success or failure.

In the given four options, (a), (c) and (d) are incorrect, because the number of outcomes are not fixed there and hence we cannot use binomial distribution.

Only option (b) will serve our purpose, as we are accurately predicting who is getting promoted at work.

Thus, the correct option is (b).

What is the actual slope of this line?
-BARSIC- [3]

Answer:

  -4

Step-by-step explanation:

The line has a "rise" between the two points of -4 units for a "run" of +1 unit. The slope is the ratio ...

  m = rise/run = -4/1 = -4.

The slope is -4.

_____

<em>Additional comment</em>

A "whole number" must be non-negative. Here, the slope is negative. If you're restricted to "a fraction or a whole number", then the appropriate answer is the fraction -4/1. We suspect that "integer" is meant where "whole number" is used.
