A family that owns two automobiles is selected at random. Suppose that the probability that the older car is American is 0.80, the probability that the newer car is American is 0.70, and the probability that both the older and the newer cars are American is 0.60.

Answers

Answer 1

Answer:

Probability [New car is also American] = 0.75

Explanation:

Given:

P(Older) = 0.80

P(New) = 0.70

P(Older and New) = 0.60

Find:

Probability [New car is also American]

Computation:

P(Older and New) = P(Older)[P(New given Old)]

P(New given Old) = 0.60  / 0.80

P(New given Old) = 0.75

Probability [New car is also American] = 0.75

Compute the weight fraction of graphite, in a 3 wt% C Ferritic Gray cast iron, assuming that all the carbon exists as the graphite phase. Assume densities of 7.9 and 2.3 g/cm3 for ferrite and graphite, respectively.

Answers

Answer:

9.60%

Explanation:

Computation for the weight fraction of graphite

First step

Computation for the mass fraction for Wa using this formula

Wa=Cg-Co/Cg-Ca

Let plug

Wa=10-3/100-0

Wa=0.97

Computation for the mass fraction for Wg using this formula

Wg=Co-Ca/Cg-Ca

Let plug in the formula

Wg=3-0/100-0

Wg=0.03

Second step is to convert the mass fraction to Volume Fraction using this formula

Volume Fraction =[Wg/Pg÷(Wa/Pa)+(Wg/Pg)]*100

Let plug in the formula

Volume =[0.03/2.3 ÷(0.97/7.9)+(0.03/2.3)]*100

Volume=[0.0130435÷0.1227848+0.0130435]*100

Volume=[0.0130435÷0.135828]*100

Volume=0.096*100

Volume=9.60%

Therefore the weight fraction of graphite will be 9.60%

How many flip-flop values are complemented in an 8-bit binary ripple counter to reach the next count value after: 0110111 and 01010110?

Answers

Answer:

- Four (4) flip-flop values will complemented

- one (1) flip-flop value will complemented

Explanation:

To find how many flip flop number of bits complemented, we just need to figure out what the next count in the sequence is and find how many bits have changed.

taking a look at the a) 00110111

we need to just 1 to the value,

so

00110111 +  0000001  = 00111000        

So here, only the first four bits are complemented.

Therefore Four (4) flip-flop values will complemented

Next

b) 01010110

we also add 1 to the value

01010110  + 00000001  = 01010111

only the first bit is complemented.

Therefore one (1) flip-flop value will complemented

1. Discuss how products incorporate aesthetic design and why this appeals to target markets 2. Discuss how the universal design process has impacted engineering design and the impact these expectations will have on the future of product design.

Answers

Explanation:

Remember, to say a product is incorporated with aesthetic design implies that its overall appearance is designed to look beautiful to the eyes of the user/buyer. For example, a clothing company whose target market is mainly focused on women's clothing would need to take into consideration that certain colors like pink, blue, etc are attractive to women more than men. So they'll have to ensure the colors of their clothing are suitable to the needs of their target market.

The Universal Design process involves building products that can be used by a wide range of users at ease. For example, you may ask yourself: Is my product/service easily accesible to those with disabilities?

Other processes include;

Defining who the users (or universe) are of the products. Involve consumers in the design.Follow the existing standards of product designEvaluate and review your universal design methods

Determine the size of memory needed for CD recording of a piece of music, which lasts for 26 minutes, is done with a 20-bit Analog-to-Digital Converter (ADC) in stereo (2 channels), at the rate of 44.1 kSa/s, with the compression factor 6 (allow 10% error margin).

Answers

Answer: the size of memory needed for the CD recording is 28.7 MB

Explanation:

so in the case of stereo, the bitrate is;

⇒ 26 × 60 × 44.1 × 10³ × 2

=   137592 × 10³  

for 10 bit

⇒ 137592 × 10³ × 10

= 1375920 × 10³ bits

now divide by 8 (convert to bytes)

⇒ (1375920 × 10³) / 8

= 171,990,000 BYTE

divide by 1000 (convert to kilobytes)

= 171,990,000 / 1000

= 171,990 KILOBYTES

now Given that, the compression ratio is 6      

so  

171,990 / 6

= 28665 KB

we know that. 1 MB = 1000 KB

x MB = 28665 KB

x MB = 28665 / 1000

⇒ 28.665 MB ≈ 28.7 MB

Therefore the size of memory needed for the CD recording is 28.7 MB

A system will never enter a deadlocked state if:__________A) the system chooses to ignore the problem altogether.B) the system uses the detection and recovery technique.C) the system uses the deadlock avoidance technique.D) None of the above.

Answers

the answer is B :))))

A system will never enter a deadlocked state if the system uses the detection and recovery technique. Thus the correct option is B.

What is deadlocked state?

A deadlock in desktop software happens when a procedure or task enters a waiting state as a result of another waiting process holding the requested system resource.

When a group of processes is in a wait state, a deadlock occurs because each process is awaiting a resource that is being held by another waiting process.

The wait-for graph must be maintained by the system in order to detect deadlocks, and the system periodically runs an operation that looks for cycles in the wait-for graph.

There is no method used by the OS to avoid or stop deadlocks. The OS checks the system on a regular basis for any deadlocks in an effort to break them. Therefore, option B is appropriate.

700.0 liters of a gas are prepared at 760.0 mmHg and 100.0 °C. The gas is placed into a tank under high pressure. When the tank cools to 32.0 °C, the pressure of the gas is 20.0 atm. What is the volume of the gas?

Answers

Answer:

The volume of the gas is 11.2 L.

Explanation:

Initially, we have:

V₁ = 700.0 L

P₁ = 760.0 mmHg = 1 atm

T₁ = 100.0 °C

When the gas is in the thank we have:

V₂ =?

P₂ = 20.0 atm

T₂ = 32.0 °C      

Now, we can find the volume of the gas in the thank by using the Ideal Gas Law:

[tex] PV = nRT [/tex]

[tex]V_{2} = \frac{nRT_{2}}{P_{2}}[/tex]    (1)

Where R is the gas constant

With the initials conditions we can find the number of moles:

[tex] n = \frac{P_{1}V_{1}}{RT_{1}} [/tex]    (2)

By entering equation (2) into (1) we have:

[tex] V_{2} = \frac{P_{1}V_{1}}{RT_{1}}*\frac{RT_{2}}{P_{2}} = \frac{1 atm*700.0 L*32.0 ^{\circ}}{100.0 ^{\circ}*20.0 atm} = 11.2 L [/tex]

Therefore, When the gas is placed into a tank the volume of the gas is 11.2 L.

It is desired to produce and aligned carbon fiber-epoxy matrix composite having a longitudinal tensile strength of 630 MPa. Calculate (a) the critical fiber length, and (b) the volume fraction of fibers necessary if (1) the average fiber diameter is 0.030 mm, (2) the average fiber length is 2.4 mm, (3) the fiber fracture strength is 5100 MPa, (4) the fiber-matrix bond strength is 17 MPa, (5) the matrix stress at fiber failure is 17.5 MPa.

Answers

Answer:

The answer is below

Explanation:

Given that:

Diameter (D) = 0.03 mm = 0.00003 m, length (L) = 2.4 mm = 0.0024 m, longitudinal tensile strength [tex](\sigma_{cd})=630\ MPa = 630*10^6\ Pa[/tex], Fracture strength

[tex](\sigma_f)=5100\ MPa=5100*10^6\ Pa,fiber-matrix\ stres(\sigma_m)=17.5\ MPa=17.5*10^6\ Pa,matrix\ strength=\tau_c=17\ MPa=17 *10^6\ Pa[/tex]

a) The critical length ([tex]L_c[/tex]) is given by:

[tex]L_c=\sigma_f*(\frac{D}{2*\tau_c} )=5100*10^6*\frac{0.00003}{2*17*10^6}=0.0045\ m=4.5\ mm[/tex]

The critical length (4.5 mm) is greater than the given length, hence th composite can be produced.

b) The volume fraction (Vf) is gotten from the formula:

[tex]\sigma_{cd}=\frac{L*\tau_c}{D}*V_f+\sigma_m(1-V_f)\\\\V_f=\frac{\sigma_{cd}-\sigma_{m}}{\frac{L*\tau_c}{D}-\sigma_{m}} \\\\Substituting:\\\\V_f=\frac{630*10^6-17.5*10^6}{\frac{0.0024*17*10^6}{0.00003} -17.5*10^6} \\\\V_f=0.456[/tex]

An astronomer of 65 kg of mass hikes from the beach to the observatory atop the mountain in Mauna Kea, Hawaii (altitude of 4205 m). By how much (in newtons) does her weight change when she goes from sea level to the observatory?

Answers

Answer:

[tex]0.845\ \text{N}[/tex]

Explanation:

g = Acceleration due to gravity at sea level = [tex]9.81\ \text{m/s}^2[/tex]

R = Radius of Earth = 6371000 m

h = Altitude of observatory = 4205 m

Change in acceleration due to gravity due to change in altitude is given by

[tex]g_h=g(1+\dfrac{h}{R})^{-2}\\\Rightarrow g_h=9.81\times(1+\dfrac{4205}{6371000})^{-2}\\\Rightarrow g_h=9.797\ \text{m/s}^2[/tex]

Weight at sea level

[tex]W=mg\\\Rightarrow W=65\times 9.81\\\Rightarrow W=637.65\ \text{N}[/tex]

Weight at the given height

[tex]W_h=mg_h\\\Rightarrow W_h=65\times 9.797\\\Rightarrow W_h=636.805\ \text{N}[/tex]

Change in weight [tex]W_h-W=636.805-637.65=-0.845\ \text{N}[/tex]

Her weight reduces by [tex]0.845\ \text{N}[/tex].

This fossil evidence suggests that In the days since she and her family had sailed away from Germany and the refugee camp, Liisi had spent many hours staring out at the ocean waves from the deck. Somehow, in the back of her mind, she had always believed they would return home to Estonia after the war. Yet, every time she had mentioned this to her parents, they just frowned and changed the subject. After they had escaped the Russians and fled to Germany, there had been no real home for them except the cramped apartment in the little German town of Geislingen where the U.S. Army housed Estonian refugees. Liisi had made good friends thereher Girl Scout troop of five had been inseparablebut now they were all scattered to the winds. Two of the girls had stayed in Germany, and the other two were going to Canada. Here she was all alone sailing to America. Feeling mighty lonely, Liisi reached into the inside pocket of her coat and pulled out a photograph. On it was her Girl Scout troop, all dressed in traditional Estonian costumes for a dance they had organized at the refugee camp. The dress Liisi wore was too small, as she had worn it back in Tallinn when she was younger. Liisi ran her thumb over the image of herself and closed her eyes as she remembered. "Liisi, hold still while I button your dress!" Her mother scolded. But Liisi was so eager to join the other kids in Tallinn's town square, she could not stop moving. At 10, she was just old enough to join in the folk dances as the city celebrated JaanipevJohn's Day, or Midsummer's Eve. The June 23 festival always made her giddy with delight, and as her mother finally released her, she gave her a swift hug and flew out the door. The square was just a few blocks away, and Liisi could hear the cheers of the crowd as she raced down the cobblestone streets. As she rounded the last corner and entered the square, the dancing had already begun. She was so glad she had paid attention when her mom taught her the traditional steps. Making her way to the front of the crowd, Liisi's school friends waved to her. She caught up to them just as the band started playing, and they arranged themselves in a line for the next dance. At that moment, Liisi could not imagine ever living anywhere else. The wind had picked up, and the ocean spray woke Liisi from her reverie. A tear had made its way down her cheek, and she wiped it away before replacing the photo in her pocket. "That was then," she told herself sternly and pushed those other thoughts away.
