Answer:

There are 11550 possible selections

Step-by-step explanation:

Given

$Men = 7$

$Women = 11$

Required

How many ways can 4 men and 4 women be selected

The keyword in the question is SELECTION and it means COMBINATION;

So, number of selection is:

$Number = Men * Women$

$Number = ^7C_4 * ^{11}C_4$

This gives

$Number = \frac{7!}{(7-4)!4!} * \frac{11!}{(11-4)!4!}$

$Number = \frac{7!}{3!4!} * \frac{11!}{7!4!}$

$Number = \frac{7 * 6 * 5 * 4!}{3!4!} * \frac{11 * 10 * 9 * 8 * 7!}{7!4!}$

$Number = \frac{7 * 6 * 5}{3!} * \frac{11 * 10 * 9 * 8}{4!}$

$Number = \frac{7 * 6 * 5}{3 * 2 * 1} * \frac{11 * 10 * 9 * 8}{4 * 3 * 2 * 1}$

$Number = \frac{7 * 6 * 5}{6} * \frac{11 * 10 * 9 * 8}{4 * 3 * 2 * 1}$

$Number = 7 * 5 * \frac{11 * 10 * 9 * 8}{4 * 3 * 2 * 1}$

$Number = 7 * 5 * \frac{7920}{24}$

$Number = 7 * 5 * 330$

$Number = 11550$

Hence;

<em>There are 11550 possible selections</em>

The gas tank of the truck holds 30 gallons the gas tank of a passenger car holds 50% less how many gallons does it hold?

love history [14]

Answer:

15 gallons

Step-by-step explanation:

To find how much the passenger car holds, we need to first find what 50% of the trucks gas tank holds.

Truck Gas Tank = 30 gallons

Now we find how much 50% of 30 is:

50% = 0.50

Total = 30 x 0.50

Total = 15 Gallons

So the passenger car holds 15 gallons of gas.

Which of the following stocks had the biggest increase in price from the previous day

SCORPION-xisa [38]

Answer:

Step-by-step explanation:

Without any calculations, you can eliminate Apple and Google: both of them suffered looses. Neither went up. They went down. eBay went up ever so slightly (0.09 on nearly 21 dollars). At least it did not loose money on the day. So it is possible.

Netflix went up $2.73 on a stock that was about 118 on it's close. So while ebay only made $.09, Netflix was the winner on the day both in absolute and % terms.
