Answer:

  330

Step-by-step explanation:

nCk can be computed from the formula ...

  nCk = C(n, k) = n!/(k!(n-k)!)

Here, that is

  11C7 = 11!/(7!(11-7)!) = 11·10·9·8/(4·3·2·1) = 11·10·3 = 330

_____

<em>Additional comment</em>

Many graphing or scientific calculators have probability functions that will compute this for you.

X subtract 9 equals 3 / 5X
Korvikt [17]

Answer:

x=22\frac{1}{2}=22.5

Step-by-step explanation:

x-9=\frac{3}{5}x

  • First, lets get rid of the fraction. I did this by multiplying both sides by 5.

5(x-9)=5(\frac{3}{5}x)\\5x-45=\frac{5}{1} *\frac{3}{5}x\\5x-45=\frac{15}{5}x\\5x-45=3x

  • We want to isolate x on one side of this equation. Let's put any values with x on one side of the equation, and normal integers on the other.

2x=45

  • Divide both sides by 2.

x=\frac{45}{2}

  • If your teacher wants you to leave your final answer as an improper fraction, your final answer is this. If they want it to be a mixed number or decimal, your final answer will be:

x=22\frac{1}{2}=22.5
