Which excerpt from "Good Country People" is the best example of figurative language? The reason for her keeping them so long was
Tomtit [17]

The excerpt from Good Country People that is an example of figurative language is D. Mrs. Hopewell had no bad qualities of her own but she was able to use other people’s in such a constructive way that she never felt the lack.

  • Figurative language refers to how writers compare things by linking words or phrases with something else in order to create meaning. There are several figurative languages such as simile, metaphor, irony, personification, hyperbole, symbolism, etc.

  • In this case, the figurative language used is irony. Irony simply means when a person says something but does something that's different. It's when there's a contrast between reality and expectation.

  • Based on the book, despite the fact that Mrs. Hopewell had no bad qualities, as she was known to be good, she influenced other people to carry out her bad acts.

In conclusion, the correct option is that Mrs. Hopewell had no bad qualities of her own but she was able to use other people’s in such a constructive way that she never felt the lack.

Assume that thermometer readings are normally distributed with a mean of 100o F and a standard deviation of 0.15o F. a) Draw and
son4ous [18]

The parameters of the normal distribution of the thermometer readings are its mean and the standard deviation

The probability that a thermometer reading is between 99.86o F and 100.07o F is 0.5403

<h3>The sketch of the normal distribution of the thermometer</h3>

The given parameters are:

  • Mean, μ = 100
  • Standard deviation, σ = 0.15

Next, we draw the normal distribution using a graphing calculator.

See attachment for the sketch of the normal distribution of the thermometer

<h3>The probability that a thermometer reading is between 99.86o F and 100.07o F</h3>

This means that:

x = 99.86 and x = 100.07

The probability is calculated as:

P(99.86 < x < 100.07) = P(x > 99.86) - P(x < 100.07)

Using the attached graph, we have:

P(99.86 < x < 100.07) = 0.5403
