2. In the real-world, humans hear sound as an analog signal. This means the signal is a continuous
waveform, which is completely processable by human ears. However, machines 'hear' sound a little
differently, as they process sound digitally, which is a discrete waveform.
When sound is recorded or transmitted electronically, the continuous (analog) waveform is sampled to
convert it to a discrete (digital) sequence. Sampling is the process of reducing a continuous-time signal
to a discrete-time signal. As the sampling rate increases, the sound quality of the recording or
transmission will improve.
The graphs below represent two different samples of a pure tone. Sample 1 is taken 8 times per unit of
time. Sample 2 is taken 16 times per unit of time.

a) why would sample 2 reproduce a better replication of the pure signal?
b) write a sinusoid model for sample 2.

Answers

Answer:

a) Sample 2 records at a more frequent rate, so compared to 1 it's a continuous waveform.  

b) y = 7.75 • cos(π/8(x))+7.75

At the avonelea country club,72% of the members play bridge and swim, and 76% play in bridge . If a member is selected at random , find the probability that the number of swims given that member plays bridge . Please round the final answer to 2 or 3 decimal places

Answers

Answer:

0.947

Step-by-step explanation:

Given that :

Play bridge and swim = 72%

Play bridge = 76%

Let play bridge = B

Swim = S

Thus ;

P(B n S) = 0.72

P(B) = 0.76

Probability that member swims given that member plays bridge

P(S | B) = P(BnS) / P(B)

P(S | B) = 0.72 / 0.76

P(S | B) = 0.947

Ricardo has just taken over his parents' restaurant. He knows after working there for many years that one of the major concerns among employees is competitive pay. Specifically, Ricardo's servers think that they are paid less than servers in similar restaurants.

To help investigate this issue, Ricardo employs a company that specializes in gathering data about pay rates for similar positions across the state. The company provides Ricardo with the following box-and-whisker plot.


Ricardo's goal is to provide his servers with competitive pay compared to other restaurants in the state. He currently pays his servers hourly rates ranging from $8.50 to $11.50, depending on experience and seniority. His median server pay is $8.83. Based on what he sees in the plot above, which of the following is an appropriate conclusion for Ricardo?
A.
Ricardo's median is consistent with the state median. Ricardo should leave his servers' pay as it is.
B.
Most of Ricardo's servers are paid more than the state median. Ricardo should leave his servers' pay as it is.
C.
Ricardo's minimum, maximum, and median are all significantly less that those of the state. Ricardo should increase his servers' pay.
D.
Almost half of other servers across the state make more than the highest paid of Ricardo's servers. Ricardo should increase his servers' pay.

The area of a rectangle is 3/5 square meter. The width is 2/5 meter. A. What is the length of the rectangle? Write your answer as a fraction in simplest form. The length of the rectangle is meters. B. How many times greater is the length than the width? Write your answer in simplest form. The length is times greater than the width.

Answers

Answer:

Step-by-step explanation:

Area of a rectangle is represented as;

A = length * width

Given

Area = 3/5 m²

Width = 2/5 m

Required

Length = x

Get the length;

From the formula

L = A/W

L = 3/5 ÷ 2/5

L = 3/5 × 5/2

L = 3/2 m

Hence the length of the rectangle is 3/2 m

Take the ratio of the length to the width as shown;

L/W = 3/2÷2/5

L/W = 3/2 * 5/2

L/W = 15/4

L = 15/4 W

Hence the length is 15/4 times greater than the width

17th Street Surf shop buys t-shirts wholesale for $5 each. They sell them after a mark p of 75%. Find the amount of mark up and the retail price. markup price: retail price: please help me

Answers

Given:

Wholesale price = $5

They sell them after a markup of 75%.

To find:

The amount of mark up and the retail price.

Solution:

We have,

Wholesale price = $5

Markup% = 75%

[tex]Markup=5\times \dfrac{75}{100}[/tex]

[tex]Markup=5\times 0.75[/tex]

[tex]Markup=3.75[/tex]

Now,

Retail price = Wholesale price + Markup

[tex]\text{Retail price}=5+3.75[/tex]

[tex]\text{Retail price}=8.75[/tex]

Therefore, the markup price is $3.75 and retail price is $8.75.
