What is the probability of choosing a number greater than 21 if a number is randomly chosen between 1 and 50?
Assuming the uniform continuous distribution, the answer is 29/49. With the uniform discrete distribution, the answer is 29/50.
How does increasing the wave speed affect the frequency?
Assuming a constant wavelength, then increasing the wave speed will increase the frequency.
How do you find the frequency if you only have seconds and height of a wave?
Assuming that seconds refers to the period, the frequency is the reciprocal (1 / period in seconds). The height of the wave is irrelevant in this case.
What is the name of an angle measuring more than 180?
A reflex angle. Assuming the angle is also less than 360 degrees.
How many 4x8 sheets of plywood you needed to cover a rectangle shaped floor measuring 16 feet by 12 feet?
Assuming you mean sheets measuring 4 feet x 8 feet... Six sheets exactly.
What is the probability of choosing a number greater than 21 if a number is randomly chosen between 1 and 50?
Assuming the uniform continuous distribution, the answer is 29/49. With the uniform discrete distribution, the answer is 29/50.
What is the past continuous of think?
Assuming that "past continuous" means the same thing as "past progressive", the answer is "was thinking".
What happens to the frequency of a wave when the wavelength goes up?
Frequency drops, assuming the velocity stays the same.
What is the lowest frequency for humans?
Assuming you mean the lowest frequency humans can hear, that's about 20 Hz.
How does increasing the wave speed affect the frequency?
Assuming a constant wavelength, then increasing the wave speed will increase the frequency.
Describe how the frequency of a wave changes as the wavelength changes?
it is directly proportional to frequency so if frequency increases wavelength also increases
What happens to the period of a wave when the frequency decreases?
The period and frequency of a wave are inversely related, i.e. the period is the time it takes for wave to go through a cycle, and the frequency is the number of cycles in a certain time period. For example, a wave with a period of 0.5 seconds would have a frequency of 2 per second. Since these properties are the inverse of each other, than they will be opposite when changing. If the period decreases (i.e. gets shorter, faster) than the frequency increases. Or vice versa.
What is the frequency if the λ equals 5cm and the f equals -5 Hz?
10
What percentage of the data in a normal distribution is represented by 1 SD of a sample?
Assuming that we have a Normal Distribution of Data, approx. 65% of the data will fall within One Sigma.
Which wavelength of light has the lowest frequency?
Assuming you mean visible light, that would be red light.
What is the frequency of light with a wavelength of 6.14x10-7?
Frequency=velocity of light/wavelength We know that the velocity of light is 3x10^8m/s From your wavelength, I am assuming that the number is in meters Thus the frequency =(3x10^8)/(6.14x10^-7) frequency = 4.8859x10^14 Hz
What is the frequency of the sound wave is?
The frequency of a sound wave is the characteristic of the wave that gives rise to the sensation of pitch, assuming that the wave is not so complex that it is perceived as white noise.
