What is the Correct Value of X in the Histogram Study?

AI Thread Summary
The discussion revolves around determining the value of X in a histogram study where 75% of students sent X or fewer messages out of a maximum of 80 calls. The initial calculation suggests that X should be 60, but the book states it as 62. Upon further review, it is clarified that the book indicates 75% sent less than 62 messages, not that 62 is the value of X. The confusion stemmed from a misinterpretation of the wording in the book. Ultimately, the issue was resolved, confirming that there was no error in the book's answer.

Homework Statement



There was study made, with a histogram shown below where the maximum number of calls made were 80, of the students who sent messages, 75% sent X or less, determine X.

Homework Equations



X/80= 0.75

The Attempt at a Solution



Now unless I'm missing something (which I'll proceed to lash myself if that's true) the answer should be 60, yet the book says 62.

Is this a misprint or am i missing something?

Are you able to upload the histogram you were provided?
 
I should have read the book answer more clearly, i just read it and it says 75% sent LESS than 62 messages, it didn't say 62 was the answer (i.e X)

Sorry folks false alarm, nothing to see here.
 

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...

Thread 'Making the denominator of a certain fraction real'

Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,## $$1+r\cos(x)+r^2\cos(2x)+r^3\cos(3x)...=\frac{1-r\cos(x)}{1-2r\cos(x)+r^2}$$ My first thought was to express it as a geometric series, where the real part of the sum of the series would be the series you see above: $$1+re^{ix}+r^2e^{2ix}+r^3e^{3ix}...$$ The sum of this series is just: $$\frac{(re^{ix})^n-1}{re^{ix} - 1}$$ I'm having some trouble trying to figure out what to...
