We need to find the number of combinations of the 15 members taken 4 at a time:
15C4=\frac{15!}{4!11!}=\frac{15\times14\times13\times12}{4\times3\times2\times1}=1365

Write 5% as a decimal.
jolli1 [7]
You cannot do it that way.  Make sure the question you wrote is correct, because you would divide 5 by 100, not 100 by 5.  A simple way is to move the decimal point two points to the left.  5% as a decimal is 0.05.  

The answer is false if the question is written this way.

The equation 2(5+7) = (2•5) + (2•7) illustrates what property?
wel

In this question, you're trying to figure out what property is being represented.

Your answer would be the Distributive Property

This is your answer because as you can see, you are "distributing" the 2 to the variables inside the parenthesis.

When you distribute the number, you would be multiplying, in which in this case there is multiplication.

Therefore, Distributive property would be the correct answer.
