Answer:
Option C, D and E
Step-by-step explanation:
=> An experiment to determine probability will include a number of trials. (it includes a number of trials. It is done multiple times having multiple trials.)
=> A probability experiment will count the number of times an event occurs. (Probability tells us how many times an event can occur.)
=> Experimental probability can be written in the form of a ratio. (Experimental Probability = )

Answer:
Step-by-step explanation:
We know that:
: The number of vibrations per second of the nylon guitar string.
: Tension.
: The length of the string.
Since varies directly with the square root of the
and inversely with
, the equation has the following form:
Where "k" is the constant of variation.
Knowing that when and
,
, we can find the value of "k":
Finally, in order to find the tension when the length is 0.3 meters and the number of vibrations is 12, you need to substitute these values and the value of "k" into and solve for
