	A deck that is half an ellipse		2016-02-28
		Steve pose la question : On your website, I was reading a question and your response from a girl named Angela in which you provided a formula by which her father, a welder, could figure out points on an arc corresponding to equal 3' intervals on a 30' chord where the vertex was 1' off the chord. Is there an equivalent formula when working with an ellipse? I suspect this change will make the calculations significantly more complex. I am building a deck that is half an oval, and would like to be able to mark out the perimeter by measuring the distance from regular intervals on the primary access to a corresponding point on the perimeter. I will then connect the points on the perimeter and cut a reasonably smooth arc. The length of the primary access will be 22' and width of the deck at the vertex is 9'. I would like to be able to know the distance from the primary axis to a point on the perimeter at equal intervals of 6" along the primary axis. Can you help? Penny Nom lui répond.

	More than half of the people said...		2013-08-26
		Lucy pose la question : Hi, The question is: Samoa 23% Brazil 41% Sri Lanka 52% Senegal 39% Armenia 37% Croatia 20% Why is the following statement true for the data above: More than half of the people said they were interested in Sri Lanka. The reason I don't understand the problem is that because the percentages add up to be greater than 100%, that means that the 500 people(as stated in the question) who participated in the survey got to pick more than once. Therefore, it is not 52% out of 100% anymore. Thanks for taking the time to answer my question. Robert Dawson lui répond.
	Expressing 0.5%		2012-02-06
		Kenneth pose la question : Hello: It is correct to express 0.5% as 5 tenths of one percent. Is it also correct to express 0.5% as 5 tenths of one-hundred percentage points or 5 tenths of one percentage point? I think it would be 5 tenths of one percentage point because 5 tenths of one-hundred percentage points would be 50 percentage points, but I'm not sure. I thank you for your reply. Penny Nom lui répond.
