How many ways can 15 people be chosen from a group of 22

anzhelika [568]

Answer:

$170544\text{ ways}$

Step-by-step explanation:

If we don't care about the order (like if we pick Bob then Joe vs Joe then Bob), then a formula is $\frac{n!}k!{(n-k)!}$ where we are picking k items from a list of n items

In our case, n=22 and k=15

Therefore, there are $\frac{22!}{15!(22-15)!}=$

$\frac{22*21*20*19*18*17*16}{(7)!}=$

$\frac{22*21*20*19*18*17*16}{7*6*5*4*3*2*1}=$

$\frac{2*11*7*3*5*4*19*6*3*17*16}{7*6*5*4*3*2*1}=$

$11*19*3*17*16=$

$170544\text{ ways}$

The federal tax code allows some items used for business purposes to be depreciated. That is, their taxable value decreases over

Phantasy [73]

Answer: T = 22,000 - 1,900n

Step-by-step explanation:

Taxable value is $22,000

The tax code allows for the depreciation of this van by $1,900 per year.

After n years therefore the total depreciation is;

= 1,900 * n

This depreciation will need to be removed from the taxable value of $22,000 to find out the taxable value left.

Formula is therefore;

T = 22,000 - 1,900n

LOOK AT THE SCREENSHOT PLS HELP!!!

Svetllana [295]

Answer:

x = 1.63 units

Step-by-step explanation:

For 30 degree angle,

Hypotenuse = x

Base = $\sqrt2$

We know that,

$\cos\theta=\dfrac{B}{H}$

B is base and H is the hypotenuse

So,

$\cos(30)=\dfrac{\sqrt2}{x}\\\\x=\dfrac{\sqrt2}{\cos(30)}\\\\x=1.63$

So, the value of x is equal to 1.63 units.
