A volleyball team had 6 boys and 5 girls on it. The team needed 2 equipment managers. The coach selected 1 player at random to b
stiks02 [169]
Ok, so first of all there are 11 players to start off with. So, the first time the coach selects a player, there is a 5/11 chance, that there will be a girl picked. After this, the number on the bottom goes down to 10. Assuming there was a girl picked, the top number is now a 4, because there is now one less girl to be chosen. So now, you multiply the first number by the second number. This is because the first condition has to happen for the second condition to occur. I hope that explains everything.

vodka [1.7K]

Answer:

3

Step-by-step explanation:

Given:

If fifteen less than two times a number is divided by six more than the number, the result is four less than 9 times the reciprocal of the number.

Question asked:

Find the number ?

Solution:

Let the number be x

As given that:-

<u>15 less than 2 times a number </u>\div<u> 6 more than the number = 4 less than 9 times the reciprocal of the number</u>

Then the equation will be:-

\frac{2x-15}{6+x} =9\times\frac{1}{x} -4\\\\ \frac{2x-15}{6+x} =\frac{9}{x} -4\\\\ \frac{2x-15}{6+x} =\frac{9-4x}{x} \\ \\

By cross multiplication:-

x(2x-15)=(6+x)(9-4x)\\2x^{2} -15x=6(9-4x)+x(9-4x)\\2x^{2} -15x=54-24x+9x-4x^{2} \\2x^{2} -15x=54-15x-4x^{2} \\

By adding both sides by 15x

2x^{2} =54-4x^{2} \\

Adding both sides by 4x^{2}

6x^{2} =54

Dividing both sides by 6

x^{2} =9

Taking root both sides

\sqrt[2]{x^{2} } =\sqrt[2]{9} \\x=\sqrt[2]{3\times3} \\x=3

Thus, the number is 3.
