A insurance office keeps track of the number of car insurance claims filed each day. Based on the data collected, it determines
Ivenika [448]

Answer:

The expected number of new claims filed each day is 1.8.

Step-by-step explanation:

We are given the following probability distribution:

P(X = 0) = 0.25

P(X = 1) = 0.15

P(X = 2) = 0.25

P(X = 3) = 0.25

P(X = 4) = 0.1

a. What is the expected number of new claims filed each day

Multiplication of each outcome by its probability, so:

E(X) = 0*0.25 + 1*0.15 + 2*0.25 + 3*0.25 + 4*0.1 = 1.8

The expected number of new claims filed each day is 1.8.

Identify each function as a constant, direct variation, absolute value, or greatest integer function.
Anton [14]
None of those describe this function.

It's not a constant function, because it is not equal to a constant (something that isn't a variable)

It doesn't show direct variation, because it can't be represented in the form
y = kx.

It isn't an absolute value function because the absolute value isn't taken anywhere.
If it was an absolute value function it would look something like this:
g(x) = |x+3|

It isn't a greatest integer function, because the greatest integer isn't taken anywhere.
If it was a greatest integer function it would look something like this:
g(x) = \left \lfloor{x + 3}\right \rfloor

Are you sure you typed that question right?
