What kind of reaction is a plus bc b plus ac?
associative? single replacement
What basic type of reaction is illustrated by the general equation A BC ---- B AC?
Without an equality sign the information given can't be considered as an equation
A and b are events with complements ac and bc and if p of a is point 3 and p of b is point 5 find p of ac and bc?
The probability of ac and bc is 1/5.
Why does distributive property of addition over multiplication only works when the fractions are equal to 1?
There is no distributive property of addition over multiplication. The equation works if a + (b * c) = (a + b)*(a + c) = a2 + ab +ac +bc => a + bc = a2 + ab +ac +bc ie a = a2 + ab + ac = a*(a+b+c) and that, in turn requires that a = 0 or a+b+c = 1 If a, b and c are fractions than the second condition requires the fractions to sum to 1 - not be equal to 1.
How is a plus b over a minus b equals c plus d over c minus d?
(a + b)/(a - b) = (c + d)/(c - d) cross multiply(a + b)(c - d) = (a - b)(c + d)ac - ad + bc - bd = ac + ad - bc - bd-ad + bc = -bc + ad-ad - ad = - bc - bc-2ad = -2bcad = bc that is the product of the means equals the product of the extremesa/b = b/c
