One spool contains 423 yards of twine. A second spool contains 11 feet of twine.

How much twine do the two spools contain altogether?

14 ft

15 2/3 ft

25 ft

35 1/3 ft

0.23

Step-by-step explanation:

Given that while investigating customer complaints, the customer relations department of Sonic Air found that 15 percent of the flights arrive early and 25 percent arrive on time.

i.e. remaining 60% arrive late.

Overbooked = 65%

Hence not overbooked = %

Late or not overbooked = 72%

Late of not overbooked = Late+not overbooked - both

Probability for late and not overbooked = 23% = 0.23
