I'm trying to investigate this statement: The sum of n consecutive numbers is always divisible by n.
I've found already that it's only true when the total amount of numbers is an odd number. I've also found that the median and mean are the same with consecutive numbers. I can not prove that the...
I have attached a screenshot of the question. The methodology and answer that makes sense to me is the following:
29 (Total number of pupils) / 3 (Number of pupils who speak 3 languages) = 9.7 (1 d.p)
The answer given:
3 / 29 = 0.1 (1 d.p)
Have a misunderstood the question here? Any help is...
I understand that cos-1 = pi/3. However I'm very confused regarding the rest. I understand using the radius to work out the hypotenuse of the triangle (Formed at the circle's centre) and the segment height is the same as the triangle's base.
I'm unsure about denoting the angle at the centre...

Thank you Nascent Oxygen,
That has really cleared things up for me. I have two questions for you, if you don't mind answering them. The first question refers to the answer having to be exact form...
Just to check I understand correctly. I would calculate the approximate area of the segment area and the approximate area of the triangle and add them together.
Segment area (2.4567) + Triangle area (1.7320) = Sector area (4.1887)
4 * pi / 3 +...

Hello Nascent Oxygen,
Thank you for your feedback, I appreciate it.
The only methods I can think to check if the answer is correct is to use one of the following equations. I...
