Answer:
0.264 ; 0.079
Explanation:
Given that:
Sample size, n = 100
Probability of being active, p = 1% = 1/100 = 0.01
Using the binomial probability relation :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
Probability that more than 1 user will be active
P(x > 1) = 1 - [p(x=0) + p(x = 1)]
P(x = 0) = 100C0 * 0.01^0 * 0.99^100 = 0.366
P(x = 1) = 100C1 * 0.01^1 * 0.99^99 = 0.370
P(x > 1) = 1 - [0.366 + 0.370]
P(x > 1) = 0.264
2.)
Probability that more than 2 user will be active
P(x > 2) = 1 - [p(x=0) + p(x = 1) + p(x = 2)]
P(x = 0) = 100C0 * 0.01^0 * 0.99^100 = 0.366
P(x = 1) = 100C1 * 0.01^1 * 0.99^99 = 0.370
P(x = 2) = 100C2 * 0.01^2 * 0.99^98 = 0.185
P(x > 1) = 1 - [0.366 + 0.370 + 0.185]
P(x > 1) = 0.079

Merchandise without an expiration date like electronics, tools and home goods typically have a longer
Answer:
Shelf life.
Explanation:
In Business, an inventory is a term used to describe a list of finished goods, goods still in the production line and raw materials that would be used for the manufacturing of more goods in a bid to meet the unending consumer demands.
Simply stated, an inventory can be classified into three (3) main categories; finished goods, work in progress, and raw materials.
An inventory is recorded as a current asset on the balance sheet because it's primarily the most important source of revenue for a business entity.
Also, the three (3) main cost concept associated with an inventory are;
1. First In First Out (FIFO).
2. Last In First Out (LIFO).
3. Weighted average cost.
Shelf life can be defined as a measure of the length of time that a particular product could be kept or stored without it getting bad or becoming unsuitable for use by the consumers. Thus, the shelf life of a product is largely dependent on its expiration date.
Hence, merchandise without an expiration date like electronics, tools and home goods typically have a longer shelf life.
3 cm of water evaporated from a 200-hectare vertical walled reservoir during 24 hours. Storm water was added to the reservoir at a constant rate of 3 m3/s during this period. Determine the volume in ha-cm of water released during the period (through the bottom of the reservoir) if the water level was the same at the beginning and the end of the day.
Answer:
water released through the bottom of the reservoir in 24 hrs is 1992 ha-cm
Explanation:
Given the data in the question;
A = 200 hectare = 2 × 10⁶ m²
water evaporated Ve = 2 × 10⁶ m² × 3 × 10⁻² = 60000 m³ { in 24 hrs }
Water added by storm in 24hrs Vi = 3 × 24 × 3600 = 259200 m³
now let water released be Vr
ΔV = V_ini - V_final = 0
Vi - Ve - Vr = 0
Vr = Vi - Ve
Vr = 259200 m³ - 60000 m³
Vr = 199200 m³ = 19920000 m² - cm
Vr = 1992 ha-cm
Therefore, water released through the bottom of the reservoir in 24 hrs is 1992 ha-cm

An automobile having a mass of 1100 kg initially moves along a level highway at 120 km/h relative to the highway. It then climbs a hill whose crest is 80 m above the level highway and parks at a rest area located there. Use a reference with kinetic and potential energy each equal to zero for the stationary highway before the hill. Let g = 9.81 m/s^2.
For the automobile, determine its change in kinetic energy and its change in potential energy, both in kJ. For the automobile, determine its change in kinetic energy, in kJ.
a. -8594
b. -663.1
c. -6.63x10^5
d. 663.1
Answer:
[tex]-6111.11\ \text{kJ}[/tex]
[tex]863.28\ \text{kJ}[/tex]
Explanation:
m = Mass of automobile = 1100 kg
v = Velocity of car = 120 km/h = [tex]\dfrac{120}{3.6}\ \text{m/s}[/tex]
h = Height of hill = 80 m
g = Acceleration due to gravity = [tex]9.81\ \text{m/s}^2[/tex]
Change in kinetic energy
[tex]KE=\dfrac{1}{2}m(u^2-v^2)\\\Rightarrow KE=\dfrac{1}{2}\times 1100\times (0-(\dfrac{120}{3.6})^2)\\\Rightarrow KE=-611111.11\ \text{J}[/tex]
Change in kinetic energy is [tex]-6111.11\ \text{kJ}[/tex]
Change in potential energy is given by
[tex]PE=mgh\\\Rightarrow PE=1100\times 9.81\times 80\\\Rightarrow PE=863280\ \text{J}[/tex]
The change in potential energy is [tex]863.28\ \text{kJ}[/tex].

A communications system transmits a message. The probability that the message will be received is p. To be confident that a message is received at least once, the system transmits it n times. If a message is received, the receiver turns off and does not turn back on.
a. Assuming all transmissions are independent, what is the PMF of K, the number of times the pager receives the same message?
b. Assume p=0.8. What is the minimum value of n that produces a probability of 0.95 of receiving the message at least once?
Answer:
Follows are the solution to the given points:
Explanation:
In point a:
In the PMF of K, that pager receives its same message number of times, that is [tex]=\tiny \binom{n}{k}p^{k} (1-p)^{n-k}[/tex]
In point b:
The possibility of getting number of cultural at least once in x:
[tex]\to 1-P(\text{not receiving it at all})\\\\\to 1-(0.2)x\\\\\to 1-(0.2)x>0.95\\\\\to (0.2)x<0.05 \\\\[/tex]

Under conditions for which the same room temperature is maintained by a heating or cooling system, it is not uncommon for a person to feel chilled in the winter but comfortable in the summer. Consider a room whose air temperature is maintained at 24ºC throughout the year, while the walls of the room are nominally at 26°C and 16°C in the summer and winter, respectively. The exposed surface of a person in the room may be assumed to be at a temperature of 32°C throughout the year and to have an emissivity of 0.90. The coefficient associated with heat transfer by natural convection between the person and the room air is approximately 2 W/m2·K.
Answer:
Hello your question is incomplete below is the missing part of your question
Determine Heat flux due to convection
answer : 16 w/m^2
Explanation:
Room temperature = 24°c
Room temperature during summer = 26°c
Room temperature during winter = 16°c
surface temp of person = 32°C
emissivity = 0.90
coefficient ( h ) = 2 W/m2.K
Determine Heat flux due to convection
Q" = h ( Δ T ) = coefficient * ( surface temp of person - room temperature )
= 2 * ( 32 - 24 ) = 16 w/m^2
