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.

70. Write the standard form of the equation of the line with

nasty-shy [4]

Answer:

y = -2x - 8

Step-by-step explanation:

Use the point slope form: (y - y1) = m(x - x1)

(y - (-4)) = -2(x - (-2))

y + 4 = -2(x + 2)

y + 4 - 4 = -2x - 4 - 4

y = -2x - 8

Answer: y = -2x - 8
