Answer:

The numbers are: 1 and 3.

Step-by-step explanation:

Let the first number be $ x $ and the second number be $ y $.

Given: The difference between twice the number and the second number is $ -1 $. writing this mathematically,

$ 2x - y = -1 $

From the second statement we get:

$ 2y + 3x = 9 $

Solving for $ x$ and $ y$ we get:

$ x = 1 $

and $ y = 3 $

Thus the first number is 1 and the second number is 3.

<h3>What is the mean of a discrete distribution?</h3>

The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.

Hence, considering the table, the mean of the discrete distribution is:

E(X) = 23 x 0.16 + 25 x 0.09 + 26 x 0.18 + 31 x 0.12 + 34 x 0.24 + 38 x 0.21 = 30.47.

Hence option B is correct.
