Mark got 54 out of 66 correct in his test. What fraction of the marks did he get correct? Give your answer in its simplest form
elixir [45]

Answer:

\texttt{Fraction of the marks did he get correct}=\frac{9}{11}

Step-by-step explanation:

Mark got 54 out of 66 correct in his test.

We need to find what fraction of the marks did he get correct,

Total number of questions = 66

Total number of correct answers = 54

\texttt{Fraction of the marks did he get correct}=\frac{\texttt{Total number of correct answers}}{\texttt{Total number of questions}}\\\\\texttt{Fraction of the marks did he get correct}=\frac{54}{66}\\\\\texttt{Fraction of the marks did he get correct}=\frac{9}{11}

How many ways can a committee of 6 be selected from a club with 10 ​members
Ratling [72]

Answer:

210

Step-by-step explanation:

The general formula for picking k items from a total of n is

_{n}C_{k} = \frac{n! }{(n-k)!k! }

Thus, if we want to select a committee of six people from a club with 10 members, the number of combinations is

_{10}C_{6} = \frac{10! }{(10-6)!6! }

= \frac{10! }{4!6! }

= \frac{10\times9\times8\times7}{4\times3\times2\times1 }

= \frac{5040 }{24 }

= 210

The committee can be selected in 210 separate ways.
