Answer:

Step-by-step explanation:

To find the mean of a set of numbers, add all the numbers together. Then, divide the sum by how many numbers you had to begin with.

Add the numbers together:

10 + 12 + 15 + 11

= 48 This is the sum of the data

Count how many numbers you had:

10, 12, 15 and 11 are FOUR numbers (amount of data).

Divide the sum of the data by the amount of data.

48 ÷ 4 = 12 This is the mean

The mean of 10, 12, 15, 11 is 12.

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.

Answer:

The result of the integration is $\frac{x^5}{5}$

Step-by-step explanation:

Integration of a power of x:

The integration of a power of x is:

$\int x^{n} dx = \frac{x^{n+1}}{n+1}$

In this question:

$n = 4$ . So

$\int x^{4} dx = \frac{x^{4+1}}{4+1} = \frac{x^5}{5}$

The result of the integration is $\frac{x^5}{5}$
