The Arithmetic Mean and Median of the given set of data ( 2, 5, 13, 15, 19, 21 ) are 12.5 and 14 respectively.
<h3>What is Arithmetic mean?</h3>
Arithmetic mean is simply the average of a given set numbers. It is determined by dividing the sum of a given set number by their number of appearance.
Mean = Sum total of the number ÷ n
Where n is number of numbers
Median is the middle number in the data set.
Given the sets;
Mean = Sum total of the number ÷ n
Mean = (2 + 5 + 13 + 15 + 19 + 21) ÷ 6
Mean = 75 ÷ 6
Mean = 12.5
Median is the middle number in the data set.
Median = ( 13 + 15 ) ÷ 2
Median = 14
Therefore, the Arithmetic Mean and Median of the given set of data ( 2, 5, 13, 15, 19, 21 ) are 12.5 and 14 respectively.

Answer:
C. She left out a zero between the two and the five
Step-by-step explanation:
Given that Susan is expected to convert 12,050,000 to scientific notation, what Susan should have done is shown below:
Count the number of decimal places from your right up to before the first digit, and place the decimal point after the first digit. The number of decimal places counted would determine the exponent we are to use.
Here, we have 7 decimal places, counting from the right to the left, therefore, the exponent would be a positive 7.
What Susan should have is:
1.205 × 10⁷ NOT 1.25 × 10⁷.
1.25 × 10⁷ = 12,500,000, which is different from 12,050,000.
Her paper was marked wrong because: "she left out a zero between the two and the five"
It means the variable y is equal to the negative variable of x.
