15th daily puzzle...

Time passes so quickly...
i've been blogging consistently for 15 days !
Hope you've found this entertaining...mildly ?
:P

Maths is a universal language.
No doubt.
But, still there are different symbols used for the same function/effect.
Today's puzzle is a good example.
In S'pore, we would read it commonly as 0.0666666666666666666666666666666666666666666666666666666666666666666666666666666...
Ok, well you get it.
The digit 6 recurrs endlessly... like crazy (that's why we call such numbers irrational.)

So, what's the mystery number, whose reciprocal is approximately 0.0667 (3 sig. fig.)

daily question

Now, here's a question you don't often see.
Do you understand the notation ?

Need an interpretation ?
Let's say, there are two sets. 
Set A is the modulus of 2x-3 equivalent to 13. 
Set B is -3x + 2 smaller than or equal to -4.
Both sets only contain elements that are real numbers.
(Do you remember what's a real number ?)
So, the question for today is: what elements appear in both sets A and B ?

Let's laugh !

If a smiling kangaroo's not smiling (cos she had a very bad migraine), then it's time for some humour (gotta relaxz) !





Here's some hospital jokes that my fren just emailed me today.
(Good things must share-share, right ?)

1. A man dashes into the A&E dept. and yells . . 'My wife's going to have her baby in the taxi'.
I grabbed my stuff, rushed out to the taxi, lifted the lady's dress and began to take off her underwear. Suddenly after protests from the lady I noticed that there were several taxis - - - and I was in the wrong one.

2. At the beginning of my shift, I placed a stethoscope on an elderly and slightly deaf female patient's anterior chest wall.
'Big breaths,'. I instructed.
'Yes, they used to be,'. . . replied the patient..

3 One day I had to be the bearer of bad news when I told a wife that her husband had died of a massive myocardial infarct. Not more than five minutes later, I heard her on her mobile phone reporting to the rest of the family that he had died of a 'massive internal fart.'

4. During a patient's two week follow-up appointment, he told me that he was having trouble with one of his medications.
'Which one ?'. . .. I asked.
'The patch; the Nurse told me to put on a new one every six hours and now I'm running out of places to put it!'
I had him quickly undress and discovered what I hoped I wouldn't see. Yes, the man had over fifty patches on his body!
Now, the instructions includes removal of the old patch before applying a new one.

5. A nurse was on duty in the A&E when a young woman with purple hair styled into a punk rocker Mohawk, sporting a variety of tattoos, and wearing strange clothing, entered . . It was quickly determined that the patient had acute appendicitis, so she was scheduled for an immediate operation..
When she was completely disrobed on the operating table, the staff noticed that her pubic hair had been dyed green, and above it there was a tattoo that read . .'Keep off the grass'
Once the surgery was completed, the surgeon wrote a short note on the patient's dressing, which read 'Sorry . . . had to mow the lawn.'
