Alocal concert center reports that it has been experiencing a 15% rate of no-shows on advanced reservations. among 150 advanced reservations, find the probability that there will be fewer than 20 no-shows. round the standard deviation to three decimal places to work the problem.
a) 0.7967
b) 0.3187
c) 0.2451
d) 0.754

C

Step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

$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
