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.

Simplify: (2x2 − 9x + 3) + (−7x2 + 4x − 2)

Leokris [45]

Combine like terms
2x^2 + -7x^2 = -5x^2
-9x + 4x = -5x
3 + -2 = 1
put back together
-5x^2 - 5x +1

If I can paint 96 sq ft in 15 minutes how long does it take to paint 1 sq ft

White raven [17]

It takes 0.15625 minutes to paint 1 square feet

Solution:

Given that, I can paint 96 sq ft in 15 minutes

To find: Time taken to paint 1 square feet

From given,

96 square feet is painted in 15 minutes

Let "x" be the time taken to paint 1 square feet

Then, we can say,

96 square feet = 15 minutes

1 square feet = x minutes

This forms a proportion and we can solve the sum by cross multiplying

$96 \times x = 15 \times 1\\\\x = \frac{15}{96}\\\\x = 0.15625$

Thus it takes 0.15625 minutes to paint 1 square feet

PLAEASE HELP ME If the equation of a line is 2y+3x=3, what is the y intercept of the line?

Alja [10]

Answer:

3/2

Step-by-step explanation:

2y+3x=3

This represents a linear equation and the format for a linear equation is

y = mx+b

m = slope

b= y-intercept

we have to subtract 3x from both sides to make this the y=mx+b form

2y=-3x+3

and divide both sides by 2

y = (-3x+3)/2

3/2 or 1.5 is the y-intercept

the constant of a linear equation (or 3) is the y-intercept, if there is no constant then the y-intercept is 0
