Acomputer is programmed to scan the digits of the counting numbers. for example, if it scans  1 2 3 4 5 6 7 8 9 10 11 12 13  then it scanned 17 digits altogether. if the computer begins it's task and scans the first 1392 digits starting with 1, what is the last counting number scanned?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
