natima [27]

Answer:

  • <em>Mode is 0</em>
  • <em>Median is 1 </em>
  • <em>Mean is 2.625</em>

Step-by-step explanation:

  • <em>To find the mode, or modal value, it is best to put the numbers in order. A number that appears most often is the mode.</em>
  • <em>0, 0, 0, 1, 2, 4, 7, 7 = mode is 0</em>

<em></em>

  • <em>To find the Median, place the numbers in value order and find the middle number.</em>
  • <em>0 , 0 , 0 , 1 , 2 , 4 , 7 , 7 = median is 1</em>

<em></em>

  • <em>The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are.</em>
  • <em>0 + 0 + 0 + 1 + 2 + 4 + 7 + 7 / 8 = mean is 2.625</em>

Answer:

It would be <u>97.50</u> square deckles.

Step-by-step explanation:

Given:

1 deckle = 75.9 yodels.

Now, to get the square deckles.

As given, 1 deckle = 75.9 yodels.

So, to get the square deckles by using conversion factor:

<em>75.9 yodels = 1 deckle.</em>

7400 yodels² = 7400\div 75.9

                       = 97.50\ deckels ^2.

Therefore, it would be 97.50 square deckles.
