Find the average of 1.11, 0.01, 0.101. 0.001, 0.11

Options

A. 0.2664
B. 0.2554
C. 0.1264
D. 0.1164

Answer

To find the average of the numbers 1.11, 0.01, 0.101, 0.001, and 0.11, we will follow these steps:

### Step 1: List the numbers
The numbers we need to find the average of are:
- 1.11
- 0.01
- 0.101
- 0.001
- 0.11

### Step 2: Calculate the sum of the numbers
Now, we will add all these numbers together:
\[ 1.11 + 0.01 + 0.101 + 0.001 + 0.11 \]

Calculating the sum:
\[ 1.11 + 0.01 = 1.12 \]
\[ 1.12 + 0.101 = 1.221 \]
\[ 1.221 + 0.001 = 1.222 \]
\[ 1.222 + 0.11 = 1.332 \]

So, the total sum is:
\[ 1.332 \]

### Step 3: Count the number of observations
Next, we count the number of observations. In this case, we have:
- 1.11
- 0.01
- 0.101
- 0.001
- 0.11

This gives us a total of 5 observations.

### Step 4: Calculate the average
Now, we can calculate the average using the formula:
\[ \text{Average} = \frac{\text{Sum of all observations}}{\text{Number of observations}} \]
Substituting the values we found:
\[ \text{Average} = \frac{1.332}{5} \]

Calculating the average:
\[ \text{Average} = 0.2664 \]

### Final Answer
The average of the numbers 1.11, 0.01, 0.101, 0.001, and 0.11 is **0.2664**.
