Answer:
B. 0.602%
Step-by-step explanation:
Probability is essentially (# times specific event will occur) / (# times general event will occur). Here, we have a few specific events: draw a quarter, draw a second quarter, draw a penny, and draw another penny. The general event will just be the number of coins there are to choose from.
The probability that the first draw is a quarter will be 4 / (4 + 8 + 9) = 4/21.
Since we've drawn one now, there's only 21 - 1 = 20 total coins left. The probability of drawing a second quarter is: (4 - 1) / (21 - 1) = 3/20.
The probability of drawing a penny is: 9 / (20 - 1) = 9/19.
The probability of drawing a second penny is: (9 - 1) / (19 - 1) = 8/18.
Multiply these four probabilities together:
(4/21) * (3/20) * (9/19) * (8/18) = 864 / 143640 ≈ 0.602%
The answer is B.

Step-by-step explanation:
$1312.50×1.5%÷100
=20.25 that's taxable income
or
you can say $1312.50- 1.5%
=20.25
Answer:
Option 3.
Step-by-step explanation:
The given function is
where, h(t) is the height of a small rock falling from the top of a 124-ft-tall building and t is the time in seconds.
It is a downward parabola.
Equate the function equal to 0, to find the time at which the rock touch the ground.
If 
, the according to the quadratic formula
Using quadratic formula, we get
Time cannot be negative. So, the rock remain in the air in the interval 0 < t < 2.
Therefore, the correct option is 3.
