1) Solve the proportion.
6/15=a/4

2) solve the two inequalities
1. 4k-1 ≥ -3
2. 4+x/2>2x

3) Solve each compound inequality
5m<-10 or 3m>9

4) solve each equation or inequality. If there is not solution, write no solution.
1. |y|=3
2. |5| ≤ 15

5) The ideal length of a certain nail is 20 mm. The actual length can vary from the ideal by at most 0.4 mm. Find the range of acceptable lengths of the nail.

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 %

15: 24

62.5%
