Find the mean of the first four test scores first.
(Add all numbers in set and divide by how many numbers there are)
81 + 87 + 71 + 89 = 328 / 4 = 82
Then, find the mean with the 85 added as the fifth term.
81 + 87 + 71 + 89 + 85 = 413 / 5 = 82.6
The impact that the 85 had on the mean test score was that the mean/average increased by 0.6.

<u>ANSWER: </u>
147.868 mL of water is required to make an ice cube.
<u>SOLUTION:
</u>
Given that, an ice cube is made up of 5 fluid ounces of water.
We need to find how many milli liters of water does it require to make an ice cube.
For, that we have to convert 5 fluid ounces in to units of milli liters.
We know that, 1 US fluid ounce equals to 29.5735 milli liters. i.e. 1 US fluid ounce = 29.5735 mL
Now,
An ice cube is made by 5 fluid ounces = 5 x 1 fluid ounce
= 5 x 29.5735 mL = 147.868 mL
Hence, 147.868 mL of water is required to make an ice cube.
