It is given that eyes blink 900 times each hour. To determine how many times you would blink your eyes in 8 hours multiply the number of times eyes blink in an hour by the number of hours. Multiplying 800 by 9 gives 800*9 = 7200. In 8 hours you would blink your eyes 7200 times.http://www.enotes.com/homework-help/eyes-blink-900-times-each-hour-about-how-many-455432Fri, 28 Nov 2014 08:34:45 PSTDomain and range represent all the `x` values and all the `y` values for...

Domain and range represent all the `x` values and all the `y` values for the given function. With straight line (linear) functions, the domain and range ordinarily extend between infinity and negative infinity. a) `f(x) = 2x- 3` As there are no restrictions or points given, the domain and range will be: `x in(- oo; oo)` (domain) and `y in(-oo; oo)` (range). `g(x) = 3x+1 therefore x in (-oo; oo) ` and `y in( -oo; oo)` b) `f(x) =...http://www.enotes.com/homework-help/f-x-2x-3-g-x-3x-1-b-f-x-sqrt-x-4-g-x-x-2-im-472786Fri, 28 Nov 2014 05:09:35 PSTDetermine `h(x)=(f(x))/(g(x)) ` , then determine the domain and range of...

Primary and secondary data fall within the scope of statistics and can be used as part of a research method. The collected data may assist a company in measuring, assessing and discussing the results of data collection for whatever purposes the information is required. This is where the differences between the two become relevant as some companies need a direct approach and therefore use primary data sources whereas others need previously...http://www.enotes.com/homework-help/what-primary-data-secondary-data-472774Thu, 27 Nov 2014 07:38:44 PSTWhat is primary data and secondary data in Statistics and research methods?

If I understand the game correctly, there are additional rules. At each turn, a player must choose at least one coin. Also, a player can only take coins from 1 row at a turn. Let the coins be: AABBBCCCC The first player can always win. The first move is to take three C's. (2a) Player 2 takes 1 A. Then player 1 takes 3 Bs leaving an A and C so player 1 wins (2b) Player 2 takes 2 As. Then player B takes 2 Bs leaving a B and a C.

F is an object which is a one-dimensional regular hexagon with an equilateral triangle inscribed, where the triangle and hexagon cannot move independently. The isometries of F (making up the symmetry group of F, S(F) ) are as follows - 6 rotational positions of the object, and 2 sides from which to view the object (back or front), making 12 isometries altogether. This is the same as the symmetric group of the hexagon S(Hexagon) assuming that...http://www.enotes.com/homework-help/figure-f-regular-hexagon-with-an-equilateral-472715Mon, 24 Nov 2014 19:45:20 PSTThe two line symbols meant to be right under each other in brackets, but...

The numbers N and M have to be determined such that the sum of M and N is 6 and the difference of M and N is 2. As the sum is 6, M + N = 6 The difference being 2 gives M - N = 2 and N - M = 2 Now M - N = 2 gives M = N + 2 and N - M = 2 gives N = M + 2 Substituting M = N + 2 in the equation M + N = 6 gives N + 2 + N = 6 or N = 2 The value of M is N + 2 = 4 Even if we were to take M = N + 2 the same two numbers would be obtained.
