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).

The model represents the equation <br> 4x+ 4 = 12<br> What value of x makes the equation true
myrzilka [38]

Answer:

B

Step-by-step explanation:

All you have to basically do on this one is go backwards.

The beginning equation is 4x+4=12, so to first revesre the adding we are going to use 12, the product, and subtract 4 from it (since that is what was added).

12-4=8

Now you need to reverse the times 4, so to do that just divide instead because that is the invese of multiplication.

8/4=2

Now you have 2, which is the variable, x. To make sure this is right you can just put it into the equation and see if 4x2+4 is 12

Hope this helped!
