A teacher dropped 8 coins on the table and counted the number of tails to simulate the number of questions a student might guess

correctly on a true/false quiz with 8 questions. The dot plot below shows the results of one hundred trials. Based on this data, which number of correct answers is most unlikely? a dot plot labeled 0, 1, 2, 3, 4, 5, 6, 7, 8 along the bottom. Above the zero is 4 dots. Above the 1 is 13 dots. Above the 2 is 12 dots. Above the 3 is 10 dots. Above the 4 is 8 dots. Above the 5 is 4 dots. Above the 6 is 17 dots. Above the 7 is 15 dots. Above the 8 is 12 dots.

Answer:

Get 0 tails (correct answers in the test)

Get 5 tails (correct answers in the test)

Step-by-step explanation:

This is a problem of empirical probability calculation, since the teacher tries to find by means of the experimental method, the number of correct answers that a student could correctly guess in a true / false test with 8 questions.

If the teacher throws the 8 coins and then counts the number of tails, the graph shows the frequency with which 1, 2, 3, 4, 5, 6, 7 and 8 tails are obtained in the 100 attempts.

Therefore, the least probable result was the one that was obtained less frequently in the experiment or, in other words, the one that contains fewer points in the diagram, which in this case are:

Get 0 tails (correct answers in the test)

Get 5 tails (correct answers in the test)

Sam wants to make 4 gallons of vegetable bean soup. The recipe below makes 13 gallon of soup. Help Sam make his grocery list for
Zolol [24]

The proportion of the recipe required to make the grocery list is obtained from the recipe for the beans soup.

The grocery list is therefore;

  • <u>15 cups of honey beans</u>
  • <u>9 cups carrots</u>
  • <u>12 cups cherry tomato</u>
  • <u>192 oz. vegetable broth</u>
  • <u>10.5 cup turnips</u>
  • <u>6 teaspoon salt</u>
  • <u>8 cups potato onions</u>
  • <u>1.25 teaspoons thyme</u>
  • <u>12 teaspoons garlic</u>

Reason:

Amounts of beans soup Sam wants to make = 4 gallons

<em>The recipe for the beans soup is as follows as obtained from an online home work document are</em>;

<em>Vegetable Bean Soup that Serves 4 with volume of 0.</em>\overline 3<em> gallons</em>

<em>1.25 cups of honey beans</em>

<em>0.75 cup carrots</em>

<em>1 cup cherry tomato</em>

<em>16 oz. vegetable broth</em>

<em>0.875 cup turnips</em>

<em>0.5 teaspoon salt</em>

<em />0.\overline 6<em> cup potato onions</em>

<em>0.125 teaspoon thyme</em>

<em>1 teaspoon garlic</em>

The amount of each ingredient Sam needs is given by the ratio of amount of soup Sam wants to make and the given amount of soup made by the ingredients as follows;

Multiple \ of \ ingredient \ amount = \dfrac{4}{0. \overline 3} = \dfrac{4}{\dfrac{1}{3} } = 4 \times 3 = 12

Therefore, Sam has to buy twelve times the amount of each ingredient as follows;

Vegetable Bean Soup that Serves 4 with volume of 0.\mathbf{\overline 3} gallons

12 × 1.25 = 15 cups of honey beans

12 × 0.75 = 9 cups of carrots

12 × 1 = 12 cups of cherry tomato

12 × 16 = 192 oz. vegetable broth

12 × 0.875 = 10.5 cup turnips

12 × 0.5 = 6 teaspoon salt

12 × 0.\overline 6 = 8 cups of potato onions

12 × 0.125 = 1.25 teaspoons thyme

12 × 1 = 12 teaspoons garlic

The grocery list is therefore;

  • 15 cups of honey beans
  • 9 cups carrots
  • 12 cups cherry tomato
  • 192 oz. vegetable broth
  • 10.5 cup turnips
  • 6 teaspoon salt
  • 8 cups potato onions
  • 1.25 teaspoons thyme
  • 12 teaspoons garlic
