A mechanic's paycheck for a 5-day workweek is $490. A workday is 8 hours. What is the worker's hourly pay? Paycheck

12.25 an hour

Step-by-step explanation:

there are 24 hours in a day, 24*5 (days) = 120

24/8 (the number of hours he uses each day) is 3

divide 120 by 3 and you get the amount of hours he works a week, 40

$490 (the amount he makes in a week) divided by 40 (the amount of hours he works a week) and you get your answer of $12.25 an hour

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
