When manufacturing DVDs for SONY, batches of DVDs are randomly selected and the number of defects, X, is found for each batch. Determine whether a probability distribution is given and tell why, or why not:

, the distribution is not a probability distribution.

Step-By-Step Explanation:

The distribution is given below:

A given distribution is a probability distribution if

Since, for the given distribution, , the distribution is not a probability distribution.

19.side- angle- side

20. angle- side- angle

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
