Answer:
a.
Step-by-step explanation:
(2, 10) and (4, 10) have the same y value so it's not a function etc. etc.
Building a probability distribution, it is found that the expected value for both players is of 0.25 points.
- The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the four possible outcomes, considering Player A - Player B, are:
H - H
T - H
H - T
T - T
That is, considering a success as the number of heads, the distribution is:
For Player A, the earnings of each outcome are: -1, 0 and 2
Hence, the expected value is:
For Player B, the earning of each outcome are: 2, 0 and -1.
Hence:
The expected value for both players is of 0.25 points.

Volume of a sphere = 4/3(3.14)(2.6)^3
Raise 2.6 to the third power and substitute it in the equation
Multiply that number by 3.14
Whatever your answer is, times it by 4
Then divide that answer by 3

Answer:
A. 3
Step-by-step explanation:
A term is a single mathematical expression. It may be a single number (positive or negative), a single variable ( a letter ), several variables multiplied but never added or subtracted. Some terms contain variables with a number in front of them. The number in front of a term is called a coefficient
