Data Insights Question of the Day

_____________________________
That's what I thought. ­Thank you!

Idk if this is still a doubt or not but based on what i understand if you sort the table by time and if the difference between 2 "time of update"s is less than 3 mins then the length of download is always more than 3 mins for those people.

Think of it as if u get the most of your wifi speed when you alone are on the network however if everyone around you is using the wifi too then the speed drops and your download slows down.

I apologize for the analogy in advance xD

hello. is there any way i can subscribe for DI question of the day and get it in my email?

New Table questions from OG DI Review posted in the following links. di-butler-425510.html the-entire-list-of-table-questions-from-di-review-official-guide-427334.html

is this one simply try and error ? or is there a specific method ?

The question has E written all over. The variables are not restricted so they can assume any value and answer could be yes or May not be yes. For any value of t, one could get any answer. Say t=1, so is R=a+b+c = 0? R=1-3+2=0..yes a=1, b=-3 and C=2, while R=3+1+2=6..no a=3, b=1 and C=2… E

That question is discussed here: the-rate-r-at-which-a-chemical-reaction-in-a-certain-industrial-proces-423297.html

­The rate R at which a chemical reaction in a certain industrial process proceeds is a function of time t and is given by \(R = at^3 + bt^2 + c\), where a, b, and c are constants and t > 0. Is there a positive value of t for which R = 0 ?

If we leave all that mambo jumbo out, the question essentially asks whether \(at^3 + bt^2 + c = 0\), has a solution for t, where t > 0.

(1) a > b

If all three constants are positive and t is positive, then \(at^3 + bt^2 + c\) becomes the sum of three positive values and cannot equal 0. So, in this case, no value of positive t would satisfy \(at^3 + bt^2 + c = 0\).

However, in other cases, for example, if a = 0, b = -1, and c = 1, the equation becomes t^2 = 1, which has a positive t satisfying it (t = 1).

Not sufficient.

(2) c > 0.

Similarly, we can deduce the insufficiency of this statement.

(1)+(2) Combining the statements, we still lack sufficient information. Again, we can consider the cases:

If all three constants are positive and t is positive, then \(at^3 + bt^2 + c\) becomes the sum of three positive values and cannot equal 0. So, in this case, no value of positive t would satisfy \(at^3 + bt^2 + c = 0\).

However, in other cases, for example, if a = 0, b = -1, and c = 1, the equation becomes t^2 = 1, which has a positive t satisfying it (t = 1).

Not sufficient.

Answer: E.­

­Hey - sorry for my curiosity but how much did you get in the final GMAT exam? If I may ask?

Hello! Can someone help me solve this question?

E?
