Answer:
66.67% probability of selecting a black marble from the bag.
Step-by-step explanation:
Initially there are 16 marbles, 10 of which are black and 6 of which are red.
A red marble is drawn and not put back. So now there are 15 marbles, of which 10 are black.
So there is a 10/15 = 2/3 = 0.666% 7 = 66.67% probability of selecting a black marble from the bag.
So 20% of 30 is 6
30% * 30 is 9

$21,000-16%
16% of $21,000 is $3,360
$21,000-$3,360=$17,640
1st year would be $17,640
16% of $17,640 is $2,822
$17,640-$2,822 is $14,817
2nd year would be $14,817
16% of $14,817 is $2,370
$14,817-$2,370=$12,446
3rd year would be $12,446
$12,446 rounded would be $12,447
So A) $12,447

Answer:
< 1 = 112 degrees
< 2 = 68 degrees
Step-by-step explanation:
< 1 = x
< 2 = x - 44
x + x - 44 = 180
2x = 180 + 44
x = 224/2
x = 112
