Please help #2! I’ll give first and correct brainliest!

Confused as well

Step-by-step explanation:

If there are hypothetically 10 hours a day with 100 minutes an hour and 100 seconds per minute

at 6 pm there would be 18 hours gone in the day

18 normal hours are equal to 18*60*60 = 64800 seconds

(64800 seconds) / 10000 ( for hours)

6:48 would be the replacement  time

but this answer is wrong bc it's not an option

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
