Will mark base the question off this info: an experienced cashier at a grocery store takes 2 seconds to scan each item and 40 seconds to process the customer's payment. anna bought 31 items at the grocery store. there was a glitch in the computer system that caused the processing of the payment to take longer than usual. if the total time for anna's transaction took 2 minutes, how much time did the processing of the payment (p) take?

the time for processing the payment took 58 seconds.

Step-by-step explanation:

An experienced cashier at a grocery store takes 2 seconds to scan each item and 40 seconds to process the customer's payment. If Anna bought 31 items at the grocery store, the total time for Anna's transaction would be

(31 × 2) + 40 = 62 + 40 = 102 seconds.

The time to to process the Anna's payment took longer due to glitches. If the total time for Anna's transaction took 2 minutes = 120 seconds, then the amount of time it took to process the payment (p) would be

p = 120 - 62 = 58 seconds

step-by-step explanation:

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%
