Explore forming triangles with different
2 answers:
Answer:
(A) No
(B) Yes
Step-by-step explanation:
(A) Using centimeters for example, it is not possible to create a closed or full triangle with side lengths 1cm, 5cm and 3cm. [See attachment for illustration]
(B) It is possible to create a triangle of side lengths 3cm, 4cm and 5cm. [See attachment also]
The Pythagoras Rule also applies in this case.
The sum of the squares of the lengths of the 2 shorter sides (the opposite side and the adjacent side) is equal to the square of the longest side (the hypotenuse).
(3×3) + (4×4) = (5×5)
9 + 16 = 25

The probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.
<h3>What is probability of an event?</h3>It is the ratio in an event of the number of favorable outcome to the total number of outcome of that event.
As the probability of an event can not be more than the number 1. Thus, he probability of failure of a event is equal to the difference of the 1 to the success of the event.
Mickey tosses a coin 50 times and records 27 heads. Thus, the probability of getting a head is,
The probability of not getting a head or getting a tail is,
Now, Mickey tosses the same coin three more times. The probability of getting three tails in these tosses are,
Thus, the probability of getting three tails in three tosses When Mickey tosses a coin 50 times and records 27 heads is 12,167:125,000.
