Given the bar graph above, the difference in monthly electric cost appear to be great because of the choice of scale.

In scaling, the narrower the intervals of the axis, the larger the graph and the more highlighted the relative difference between the components of the graph.

Conversely, the wider the the intervals of the axis, the smaller the graph and the less highlighted the relative difference between the components of the graph.

Therefore, to make the difference in monthly electric cost appear not to be as great, we widden the intervals on the y-axis.
i.e. 'The interval on the y-axis could be changed to count by 20s.'

The answer is A) The scale on the y-axis could be changed to 0–150.

Because the y-axis starts at 95, it makes it seem like the change is huge but it's not actually.

Scilla [17]

Answer:

The sum is 1

Step-by-step explanation:

When you add a negative number to a positive number, it is basically just subtracting the negative from the positive. To make it simple, 5 + -4 is just 5 - 4.

Hannah was wrong in saying you take the sign of the larger number because it would not matter if the first number was a million, the signs don't change based on the size of numbers.

Is the difference of two positive rational number always positive explain

Dominik [7]

No . . . while the difference represents the absolute magnitude between two numbers . . . for example . . .

The difference between 5 and 2 is . . . 3
The difference between 6.4 and 9.5 is . . . 3.1

. . . there is still the chance that the difference may be zero . . . in which case the difference is neither positive nor negative

. . . so in short . . . the answer is . . . NO
