The correct answer is x^2-2x+2=0

The explanation is shown below:

1. To solve the problem shown in the figure above, you must apply the following proccedure:

2. You have that the roots of the quadratic equation shown in the figure attached in the problem are:

x=-1±i

3. Then, you know the quadratic formula to solve quadratic equations, which is:

(-b±√(b^2-4ac))/2a

4. You can see in the figure that a=1 and c=2; then, by analizing this, you can conclude that the coefficient b is:

b=-2

5. Therefore, you can conclude tha the quadratic equation is:

x^2-2x+2=0

6. If you want to verify it, apply the quadratic formula to the quadratic equation shown above and you will obtain the roots shown in the figure.

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

Tomtit [17]

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)
