The velocity of the wave in the string is 7.43m/s

Step-by-step explanation:

Step 1:

Data obtained from the question.

Length (L) = 3.75m

Number of oscillation (n) = 20

Time (t) = 6.73 secs

Step 2:

Determination of the wavelength of the wave. This is illustrated below:

Since the wave made three (3) loops, the length is given by:

L = 3λ/2

L is the length

λ is the wavelength

Thus, we can obtain the wavelength (λ) as follow:

From the question,

Length (L) = 3.75m

Wavelength (λ) =?

L = 3λ/2

3.75 = 3λ/2

Cross multiply to express in linear form

3λ = 3.75 x 2

Divide both side by the 3

λ = (3.75 x 2)/3

λ = 2.5m

Step 3:

Determination of the frequency of the wave. This is illustrated below:

The frequency is the number of oscillations made in 1 second. Thus it can be represented mathematically as:

Frequency (f) = number of oscillation (n)/ time (t)

f = n/t

Number of oscillation (n) = 20

Time (t) = 6.73 secs

Frequency (f) =?

f = n/t

f = 20/6.73

f = 2.97s^-1

Step 4:

Determination of the velocity of the wave.

Velocity is related to the wavelength and frequency by the following equation:

Velocity = wavelength x frequency

V = λf

Wavelength (λ) = 2.5m

Frequency (f) = 2.97s^-1

Velocity (V) =?

V = λf

V = 2.5 x 2.97

V = 7.43m/s

Therefore, the velocity of the wave in the string is 7.43m/s

Now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event aâ†µect the mean and standard deviation of the wait time until success?
