Answer:
A is the table which shows linear function.
Step-by-step explanation:
It is because there is equal interval between two numbers in the table.

You don't have the graph icon here, so we'll have to graph this parabola without it.
Your parabola is y = -x^2 + 3., which resembles y = a(x-h)^2 + k. We can tell immediately that this parabola opens down and that the vertex is (0,3).
Plot (0,3). Besides being the vertex, this point is also the max. of the function.
Now calculate four more points. Choose four arbitrary x-values, such as {-2, 1, 4, 5} and find the y value for each one. Plot the resulting four points. Draw a smooth curve thru them, remembering (again) that the vertex is at (0,3) and that the parabola opens down.
Answer:
Now we can find the expected value with this formula:
And replacing we got:
Step-by-step explanation:
For this case we know the following probability mass function given:
For this case we need to satisfy the following condition in order to have a probability distribution function:
And we have this:
Now we can find the expected value with this formula:
And replacing we got:
Answer:
: 1: Exact form : v = - 1/27
: 2 : Decimal form : v = -0.037037037037037037037037...
Step-by-step explanation: Multiply the equation to remove your variable (v) from the denominator.
I hope this helps you out.
