Ateacher asks her 20 students to each write a book report, but 6 students do not complete the assignment. the teacher randomly chooses 5 students to present their reports. what is the approximate probability the teacher has selected only students who completed the assignment? 8% 13% 17% 19%

13%

Step-by-step explanation:

When the teacher selects the first student, there is a 14/20 probability that the student completed the assignment.

When the teacher selects the second student, there is a 13/19 probability that the student completed the assignment.

Repeating the pattern, the total probability is:

P = (14/20) (13/19) (12/18) (11/17) (10/16)

P = 0.13

yes

step-by-step explanation:

yes

$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
