What is the median of 0.8, 1.0, 2.7, 2.8, 3.1, 13.3
tresset_1 [31]

Answer:

2.75

Step-by-step explanation:

<u>Step 1:  Determine the median</u>

0.8, 1.0, 2.7, 2.8, 3.1, 13.3

The median of a set is the middle of the set.  In this instance, we have 6 numbers so we don't have a number directly in the set representing the median.  Instead, we need to find the average or middle between the 3rd and 4th number.  So we take 2.7 and 2.8, add them together to get 5.5 and then we divide by 2 to get 2.75 which is our median.

Answer:  2.75

What is the median for the following set of data? 2, 3, 6, 8, 9, 10, 11
Inessa05 [86]

Answer:

The median value will be 8.

Step-by-step explanation:

The simplest way to think of a median is as a sort of "middle" value. We want to arrange our numbers from lowest to highest, then select the one in the middle. Here is another example:

3, 5, 2, 7, 3, 9, 1, 4, 7

The first step is to order these numbers from lowest to highest, like so:

1, 2, 3, 3, 4, 5, 7, 7, 9

The number in the middle of this set is 4.

The problem you have presented, as well as the above example, both deal with an odd amount of numbers. Your problem has seven numbers, and the example I gave has nine. For any odd amount of numbers, the median is the value in the middle. But what about an even amount of numbers?

Consider:

9, 4, 3, 7

Let's rearrange this:

3, 4, 7, 9

Now, there will be two "middle" values: 4 and 7. The median value will be the average of these two values:

\text{median} = \frac{4 + 7}{2} = \frac{11}{2} = 5.5

I hope that helps!

Answer:

  • Architect - $83000
  • Lawyer - $128000

Step-by-step explanation:

  • Salary of a lawyer = l
  • Salary of an architect = a

<u>According to the question we have:</u>

  • l = 2a - 38000
  • l + a = 211000

<u>Substitute l into the second equation and solve for a:</u>

  • 2a - 38000 + a = 211000
  • 3a = 211000 + 38000
  • 3a = 249000
  • a = 249000/3
  • a = 83000

<u>Find the value of l:</u>

  • l = 211000 - 83000
  • l = 128000
