Answer:

The speed of the periodic wave is 3 meters per second.

Step-by-step explanation:

Given that:

Wavelength of the periodic wave = 1 m

Frequency of the periodic wave = 3 Hz

We have to find the speed of the wave.

Speed of wave = Wavelength * Frequency of wave

Speed = fλ

Speed = 1*3

Speed = 3 m/s

Hence,

The speed of the periodic wave is 3 meters per second.

A company has 125 personal computers. The probability that any one of them will require repair on a given day is 0.15.
mariarad [96]

Answer:

a. the probability that any one of the computers will require repair on a given day is constant

Step-by-step explanation:

The following properties must be true in order for a distribution to be binomial:

- A fixed number of trials (125 computers)

- Each trial is independent of the others (one computer requiring repair does not interfere with the likelihood of another requiring repair).

There are only two outcomes (requires repair or do not require repair)

The probability of each outcome remains constant from trial to trial (All computers have the same likelihood of requiring repair, 0.15).

Therefore, the alternative that better fits those properties is alternative a. the probability that any one of the computers will require repair on a given day is constant

A die is rolled and the results are 1, 2, 1, 4, 5, 6, 1, 3, 6, 6, 5, 2, 3.
ANTONII [103]
<h3>Answer: True</h3>

We have A = 2 copies of "2" showing up out of B = 13 rolls total

A/B = 2/13 = 0.1538 is the experimental probability of rolling a 2

Compare this with 1/6 which is the theoretical probability of rolling a 2 (since there is one side labeled "2" out of 6 sides total)

1/6 = 0.167 approximately

Comparing 0.1538 with 0.167 is fairly close

or you could argue that 2/13 is close to 2/12 = 1/6
