Which set of data would be best illustrated with a bar graph

Hello. This question is incomplete. The full question is:

"Which set of data would be best illustrated with a bar graph?

the effect of hours spent exercising on heart rate . the number of skyscrapers in 5 different cities . an illustration of how the humidity in the air responds to the temperature of the air . data showing how the number of hours spent studying affects the score on an exam"

the number of skyscrapers in 5 different cities

Explanation:

Bar chart is composed of bars of proportional size to a specific value. This graph consists of several bars, each with its own value and consequently with its size, providing a comparison between the values of each bar.

As already mentioned, this graph is used when there is a need to compare different sets of values. This graph has two axes, one of which shows what is being evaluated while the other shows the value of each bar.

With that, in relation to the question above, we can say that the bar graph would be ideal to represent the number of skyscrapers in 5 different cities. That way it would be possible to compare the amount of spider-skies in each city.

cuz he is really really short, assuming an unorthodox and inherently unlucky configuration of elevator buttons…

explanation:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
