Lin is paid $90 for 5 hours of work. she used the following table to calculate how much she would be paid at this rate for 8 hours of work.

amount earned/time worked

i 90 i 5 i 1/5
i 18 i 1 i
i 144 i 8 i
i i i

why was the number 1/5 used as a multiplier?

It was used as the multiplier because the 5 represents the hours she's worked. If she uses the 1/5 graph she will find the unit rate of each time she gets paid an hour.

Step-by-step explanation:

7

step-by-step explanation:

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 %
