Answer:
When the numbers in a chart vary widely from data series to data series, or when you have mixed types of data (price and volume), plot one or more data series on a secondary vertical (value) axis. The scale of the secondary vertical axis shows the values for the associated data series. A secondary axis works well in a chart that shows a combination of column and line charts. You can quickly show a chart like this by changing your chart to a combo chart.
Step-by-step explanation:
if you add 2 negatives together you get a smaller number,(farther away from zero) therefore, -3+(-1)= -4
Answer:
It will take 14.3 years
Step-by-step explanation:
Let the consumption of electricity presently be X kw/h
In the next three years, we would be expecting an increase to 3x kw/h
Since we do not know the number of years it will take, let us represent this by t years.
We can represent the consumption in the next three years by the equation;
x × (1 + 8%)^t = 3x
(1+0.08)^t = 3
(1.08)^t = 3
We can use natural logarithms to get what t is
take the natural logarithm of both sides
ln(1.08)^t = ln3
tln1.08 = ln3
t = ln3/ln1.08 = 1.0986/0.077
t = 14.3 years
<em>2.7 / 3 = 0.9.</em>
Is <em>0.9</em> greater than, or less than <em>1? </em>=)
