Answer:
Mean = Sum of all values / number of values.
Mean is usually known as the best measure of central tendency because it takes all values into account. However, it is easily affected by any extreme value or outlier. The Mean can only be defined on interval and ratio level of measurement
. In simpler terms: "The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers."
Median is the mid point of data when it is arranged in order. It is typically when the data set has extreme values or is skewed in some direction. The median is defined on ordinal, interval and ratio level of measurement
. In simpler terms: "The "median" is the "middle" value in the list of numbers.
"
Mode is the most frequently occurring point in data. It is best for nominal data set in which both median and mode are undefined. The mode is defined on nominal, ordinal, interval and ratio level of measurement. In simpler terms: "The "mode" is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list."
Hope this helps!
Answer:
3.12 *
Step-by-step explanation:
Scientific notation requires a decimal with only a ones digit and decimal digits with a power of 10.
0.000000312 can be written as 3.12 times a power of 10.
Since you would have to move the decimal point of '3.12' 7 times to the left in order to get '0.000000312', the power of ten should be -7.
Your answer should be 3.12 * .

Answer:
(8,6)
Step-by-step explanation:
All you need to do is to evaluate the location of the dot:
The format of an ordered pair is (x,y).
x is the horizontal axis, going from <em>left to right.</em> This means that Boston is 8 to the right of the center, meaning that the x value is 8.
y is the vertical axis, going from <em>down to up.</em> This means that Boston is 6 up from the center, meaning that the y value is 6.
Overall, this gives you the coordinates of (8,6).
Find the amount of water in liter for a year
3,000 gallons = 3,000 × 3.8 liters
3,000 gallons = 11,400 liters
There are 11,400 liters of water for a year
Find the amount of water in liter for a month
11,400 liters/12 months = 950 liters/month
There are 950 liters of water in a month
