Two captains need to be chosen from a fifteen person team. if the captain positions are identical, how many different ways can the two captains be selected?

In 105 different ways

Step-by-step explanation:

To solve this problem we will use combinations without repetitions.

C(n k) = V(n k) / k!

In this case n = 15 and k = 2

C(15 2) = V(15 2) / 2! = 15 · 14 / 2 = 15 · 7 = 105

The two captains can be selected in the 105 different ways (combinations).

God with you!!!

hello i am doing good for you that it's summer in your country or state ; )

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
