When to the left of the decimal point, zeros mean nothing: 2010 has 3 sig figs (counting 201 as individual numbers 2, 0, and 1 which equals 3). When to the right, they do mean something: 0.0045 has 4 sig figs (counting 0045 as individual numbers 0, 0, 4, and 5 which equals 4).
0.4846
It is y = 0
They don't necessarily. Deviations from the median in an asymmetric data set will not sum to 0. The mean is the sum of observations divided by the number of observations and some simple algebra will show that the sum of deviations from this equals 0. Unfortunately, the browser used by this site is useless for showing such work.
The z score, for a value y, is (y - 18.6)/4
If you mean 5 times 0 then it equals to 0
0 equals Equator on The Meridian Line (0 degrees)
It just means that the value of 0 is equal to the value of 0, which is correct. It's like saying 2 equals 2, or 6 equals 6, or 52657 equals 52657... you get the point.
anything multiplied by 0 equals 0
the sum of all answers is equal to 0
EF=0 means when the net force on something is 0 (zero).
It means 3 multiplied by 0, the answer to this is 0 because anything multiplied by 0 equals 0.
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
If you mean why, that is because e1 = 0. Remember that logarithm is the inverse operation to exponentiation.
yes
When x = 0, the point that has (0, y) coordinates will be on the y-axis for any y.
