Read the passage.
the wild gander leads his flock through the cool night,
ya-honk he says, and sounds it down to me like an invitation . .
what element of style is used in this passage from “song of myself” by walt whitman?

Onomatopoeia Is the Answer.

The onomatopoeia is a literary device where the author uses a word to imitate or suggest the sound that is describing, this make the description more communicative and fascinating, It drives the reader to actually picture the sound, in this case Whitman uses “Ya-honk” as an onomatopoeia to create this effect.

- Preventive Maintenance

Explanation:

Given that,

No. of breakdowns          0      1       2       3      4

Frequency                        9      2       4       4      1

So,

No. of breakdowns          Monthly probability

      0                                        0.45

       1                                         0.10

       2                                         0.20

        3                                        0.20

        4                                        0.05

 Total                                          1.00

As per the above data,

The breakdowns expected every month = (0 * 0.45) + (1 * 0.10) + (2 * 0.20) + (3 * 0.20) + (4 * 0.05)

= 1.30

∵ The cost expected for the breakdowns every month = 1.30 * $400

= $ 520

Now,

Per month cost of preventive maintenance = (0.5 * $400) + $200

= $ 400

Thus, preventive maintenance would be more economical.
