Step-by-step explanation:
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.
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

Vincent has already finished 5 oil changes today, and can complete more at a rate of 1 oil change per hour. Warren just came on shift, and can finish 2 oil changes every hour. Sometime during the day, the friends will be tied, with the same number of oil changes completed. How long will that take? How many oil changes will Vincent and Warren each have done?
Answer:
Oil changes = 5
Vincent = 10 oil changes
Warren = 10 oil changes
Step-by-step explanation:
Vincent = 5 + h
Warren = 2h
Where,
h = number of oil changes
How long will that take?
Vincent = Warren
5 + h = 2h
5 = 2h - h
5 = h
h = 5
Number of oil changes = 5
How many oil changes will Vincent and Warren each have done?
Vincent = 5 + h
= 5 + 5
= 10 oil changes
Warren = 2h
= 2(5)
= 10 oil changes

Step-by-step explanation:
The temperature in the morning was -2 degrees. The temperature is dropping at a constant rate, and 4 hours later the temperature is now -22 degrees. How many degrees did the temperature change each hour?
Given:
Temperature in the morning = -2 degrees.
Temperature is dropping at a constant rate.
Temperature after 4 hours = -22 degrees.
To find:
The rate of change of temperature.
Solution:
Let y be the temperature after x hours from the morning.
Temperature in the morning is -2 degrees. It means, the ordered pair is (0,-2).
4 hours later the temperature is now -22 degrees. It means, the ordered pair is (4,-22).
Now, formula for average rate of change or slope is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-22-(-2)}{4-0}[/tex]
[tex]m=\dfrac{-22+2}{4}[/tex]
[tex]m=\dfrac{-20}{4}[/tex]
[tex]m=-5[/tex]
Therefore, the change in temperature is -5 per hour. It means the permutate is decreasing by 5 degrees per hour.
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
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.

Move the decimal after the number 1.
O Move the decimal after the number 9.
O Drop all of the zeroes following the number 9.
O Count the number of positions to move the decimal place.
Answer:
i think it is Move the decimal after the number 1.
Step-by-step explanation:
it the text it says
"To convert our example, 602,200,000,000,000,000,000,000, into a scientific notation, the first step is to place a decimal after the digit 6, and then drop all the zeros after the 2. This will leave us with a coefficient of 6.022. Next, to find the exponent, count the number of times you had to move the decimal point until it landed after the first digit of the coefficient. The answer is 23; therefore, the scientific notation is 6.022 x 1023. In cases where the numbers are multiples of 10, only the base number 10 and the exponent can be used. For instance, the number 1,000,000,000, can be written as 109. Now you try it. What is the scientific notation for a light year, which has been estimated at 9,500,000,000,000 km? As you read the information in this lesson, challenge yourself by converting the large numbers into scientific notations."
Awnser:
(C) Move the decimal after the number 1.

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.

If 30/t = 18/r, then t/r =
Answer:
5/3
Step-by-step explanation:
30/t = 18/r
Multiplying by r both sides,
30*r /t = 18
Dividing by 30 both sides,
r/t = 18/30 = 3/5
So, t/r = 5/3
9514 1404 393
Answer:
t/r = 5/3
Step-by-step explanation:
Every proportion can be written 4 ways. I like to think of them as "upside down and sideways." They are ...
[tex]\dfrac{30}{t}=\dfrac{18}{r}\qquad\dfrac{t}{30}=\dfrac{r}{18}\\\\\dfrac{30}{18}=\dfrac{t}{r}\qquad\dfrac{18}{30}=\dfrac{r}{t}[/tex]
__
Knowing this, you can simply rewrite your proportion as ...
t/r = 30/18
t/r = 5/3
_____
More formally, you could multiply both sides by t/18:
(30/t)(t/18) = (18/r)(t/18)
30/18 = t/r . . . . as above
Reducing the fraction gives ...
t/r = 5/3
__
Additional comments
The usually-recommended procedure for solving something like this is to "cross-multiply" as a first step. That will give ...
30r = 18t
Of course, that is equivalent to multiplying both sides by rt, the product of the denominators.
From here, to get t/r, you need to divide both sides by 18r.
(30r)/(18r) = (18t)/(18r)
30/18 = t/r
The combination of the two steps, multiply by rt, divide by 18r, is equivalent to multiplying by (rt)/(18r) = t/18, as we did above. That is, you can save some work by doing both steps at once--or by simply rewriting the proportion.

Step-by-step explanation:
Roberto has $200 in spending money. He wants to buy some video games that cost $25.50 each. Write and solve an inequality to find the number of games that Roberto can buy.
Step-by-step explanation: Each game is $25.50 which in math means it has an "x"
So if x=1 then 25.50x says that 1 video game is $25.50
Set up the equation:
200 = 25.50x (divide both sides by 25.50 to isolate the x)
200/25.50 = 7.84
x = 7.84
You can't have 0.84 of a video game, so Roberto can only buy 7 of them. The answer is correct good job!
The number of games that Roberto can buy [tex]\boldsymbol{8}[/tex] video games.
"To understand the calculation, check below."
Solve an InequalityWhen two values are compared, an inequality shows whether one is less than, greater than, or simply not equal to the other.
It's a relation that compares two integers or other mathematical expressions in a non-equal way.
Total amount with Roberto [tex]=\$ 200[/tex]
Let [tex]x[/tex] denotes number of games that Roberto can buy.
Cost of each video game [tex]=\$25.50[/tex]
So,[tex]25.50x\leq 200\\x\leq 7.8[/tex]
Therefore, Roberto can buy [tex]\boldsymbol{8}[/tex] video games.

In this activity, Julieta's students had to build triangles with these straws, without cutting them. How many different triangles could each of Julieta's students form with these straws?==========================================================
Triangle inequality theorem says that no any side of a triangle can be longer or equal to the sum the other two sidesGiven measures:
2 cm, 3 cm, 7 cm, 8 cmWe see that:
