Answer:

  • See below and attachment
  • Correct answer options are in bold and underlined

Step-by-step explanation:

The histogram shows the sizes (in acres) of 44 vineyards.

<u>a. Approximately what percentage of these vineyards are at or over 210 acres? </u>

10+13 = 23 of the vineyards are at or over 210 acres. Total is 44, so

  • 23/44*100% = 52% rounded to the nearest percent

<u>b. Describe the distribution (shape, center, spread, unusual features). </u>

  • A. The distribution is uniform.
  • <u>B. The distribution is bimodal. </u>
  • C. The distribution is unimodal.

<u>Is the distribution symmetric or skewed? </u>

  • <u>A. The distribution is skewed to the left. </u>
  • B. The distribution is symmetric.
  • C. The distribution is skewed to the right.

<u>Which of the following best describes the center? </u>

  • A. The center is best described by the mean since the distribution is symmetric and there are no outliers.
  • B. The center is best described by the median since the distribution is skewed to the right and has an outlier.
  • <u>C. The center is best described by the median since the distribution is skewed to the left and has an outlier. </u>

<u>What is the spread?</u>

  • The acreage ranges from 30 to 270 acres.  
  • 30, 90, 120, 210, 240, 270

<u>Describe any unusual features. </u>

  • A. There are no unusual features.
  • B. Most of the vineyards have close to the same number of acres.
  • <u>C. There is one vineyard that has considerably fewer acres, 0 to 30 acres, than the rest.</u>

The function f(t)=-16 + 100 models the height of a ball, in feet, dropped from a 100-foot rooftop at time t, in seconds.
Mazyrski [523]

Using it's concept, it is found that the average rate of change of the function during the interval from 0 to 2 seconds is given by:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

r = \frac{f(b) - f(a)}{b - a}

In this problem, the function is given by:

f(t) = -16t² + 100.

The outputs are given as follows:

  • f(0) = -16(0)² + 100 = 100.
  • f(0) = -16(2)² + 100 = 36.

Hence the average rate of change is given by:

r = (36 - 100)/(2 - 0) = -32 ft/s.

And the correct option is:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.
