Suppose nate wins 40% of all chess games. (a) what is the probability that nate wins two chess games in a row? (b) what is the probability that nate wins five chess games in a row? (c) when events are independent, their complements are independent as well. use this result to determine the probability that nate wins five chess games in a row, but does not win six in a row.

$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

the answer is d   i just did this haha.

d.

180 m3

let x be number of half-dollars and y be number of dimes

total value: 0.5x + 0.1y = 3.60

total amount: x + y = 24

solving this system of equations, we get that x = 3 and y = 21. (a proof of this fact has been left to the reader.) so there are 3 half dollars and 21 dimes.
