List the possible values of a for which va is between 6 and 7 and aen​

Step-by-step explanation:

The question is unclear as written. You haven’t defined va and aen. If the v is supposed to represent √, then you need to explain that. Even better, write “the square root of a” instead of “va”.

I can’t begin to guess what aen means.

6 < √a < 7

36 < a < 49

The answer is that there is no key to the graph that shows what 67 percent, 25, percent, 48 percent, or the 31 percent means. It could mean 67 percent of the people are happy, 67 percent of the animals are already fed, etc. A key would tell you what those percentages mean.
