E(X) = Expectation value = ( ∵ $5 gain so +ve and $2 loss so -ve)
=
∴ So Merrill will lose dollar
if the diameter is 5, then its radius is half that, or 2.5.
Answer:
Use Distance Formula
Step-by-step explanation:
You can find the distance between two points by using the distance formula which by definition is
For example take question 3. Plug your point values in to find the distance
Point 1 is (-1, 8)
Point 2 is (-3, -2)
You equation would look like:
This simplifies to
=
=
=
=
That is the distance between the points (-1, 8) and (-3, -2)
