Tcecarenko [31]

Answer:

Mean = 242.83

Median = 265

Step-by-step explanation:

Looking at the data set, we see there are "24" numbers.

The mean is the average, which is sum of all the numbers divided by the number of numbers.

The median is the middle value when the numbers are arranged in ascending order. Since there are even number of numbers (24), the median would be the average of 12th number and 13th number.

First, lets arrange the numbers in ascending order:

90, 100, 100, 200, 203, 224, 233, 237, 245, 257, 264, 265, 265, 266, 277, 279, 285, 288, 290, 290, 291, 291, 300

The mean is the sum of all of them divided by 24:

Mean = 242.83

The median is the average of 12th number (265) and 13th number (265). So that is:

(265+265)/2 = 265

Thus,

Mean = 242.83

Median = 265

The logarithm of 10 to base 10 is 1

<h3>How to determine the logarithm?</h3>

The given parameters are:

Base = 10
Number = 10

So, the logarithm expression can be represented as:

$\log_{10}10$

The law of logarithm states that:

$\log_{x}x = 1$

The above means that;

When the base and the number are the same, the logarithm is 1

So, we have:

$\log_{10}10 = 1$

Hence, the logarithmic value is 1
