A sound wave enters a new medium where sound travles faster. How does this affect the frequency and wavelength of the sound?
zhenek [66]

Answer:

The frequency doesn't change. If the wavespeed increases, then the wavelength must also increase ... It's just the distance the wave travels during each complete wiggle.

Step-by-step explanation:

  • Sound waves are a type of mechanical wave which requires a material medium for transmission. The transmission of such waves occurs as a result of vibration of particles in the material medium. The faster the vibration of the particles the higher the speed of the sound waves.
  • When a sound enters a new medium where the sound travels faster, it means the vibration of particles is high, and the wavelength of the waves increases which means the speed of the wave has increased. The frequency on the other hand will remain constant.

A department store wants to know what fraction of its customers in a certain market have store credit cards, and what their aver
bearhunter [10]

Answer:

The 98% confidence interval for the average credit card balance is

(564.04, 635.96).

Step-by-step explanation:

We have to calculate the 98% confidence interval on the average credit card balance.

The sample will consist of the n=30 customers that have credit card.

The sample has a mean of $600 and a standard deviation of $80.

As the population standard deviation is estimated from the sample standard deviation, we will use a t statistic.

The degrees of freedom are:

df=n-1=30-1=29

The critical value for a 98% CI and 29 degrees of freedom is t=2.463 (this can be looked up in a t-table).

Then, the margin of error is:

E=t\cdot s/\sqrt{n}=2.463*80/\sqrt{30}=197.04/5.48=35.96

Then, the upper and lower bounds of the confidence interval are:

LL=\bar X-E=600-35.96=564.04\\\\UL=\bar X+E=600+35.96=635.96
