(3) 8

Step-by-step explanation:

Note that ∆ADE is similar to ∆ABC. As such, the ratios of their legs are equal. Also note that AD = AB + BD.

BC/AB = DE/AD

BC/10 = 12/(10 + 5) = 12/15 = 4/5

or

BC = 10(4/5) = 8

A man claims to have extrasensory perception (ESP). As a test, a fair coin is flipped 23 times, and the man is asked to predict
spin [16.1K]

The probability that he would have done at least this well if he had no ESP is 4/23.

<h3>How to illustrate the information?</h3>

Probability refers to possibility. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

It should be noted that from the information, the man claims to have extrasensory perception and as a test, a fair coin is flipped 23 times, and the man is asked to predict the outcome in advance and he gets 19 out of 23 correct.

Therefore, the probability that he would have done at least this well if he had no ESP will be:

= 1 - (19 / 23)

= 4/23

Therefore, the probability is 4/23.

The formula used to find the length of a line segment is the same formula as the Pythagoras theorem.

We take CD as the hypotenuse of the right-angled triangle and the distance between the x-coordinates and y-coordinates as the length of two short sides.

We can write the formula as
CD = \sqrt{( x_{1}- x_{0})  ^{2}+ ( y_{1}- y_{0})  ^{2}  }
CD = \sqrt{(a-0)^{2}+ (b-b)^{2}  }
