First, I would take into account the important parts of the question. I'm looking for an answer in the form of "a√10, where a is an integer". I would explain if not known that an integer is just...

I would first take into account all the variables - there are red, blue and purple counters, we know the ratio of red to blue and we know the probability of purple is 0.2.
As I know the probability t...

The irrational number e is one of the most important numbers in mathematics. The value of it is 2.718... but since it is irrational that is e to 4 significant figure, only. How can we calculate this numbe...

This can be solved simultaneously. This is about manipulating the equations until they're in a format that you can use.Label the equations:eq1: -3x + 10y = -100 and eq2: 13x + 10y = 60Now, eq1 - eq2 gives...

In this question we are looking for a solution to x where the equation will equal to 0.We can first try factorising this, in the framework: (x+a)(x+b). Remembering the method of FOILS (first, outer, inner...
