What is the measure of arc e f c? 107° 180° 253° 270°
Answers
The value of arc EFC is 253 degree.
We have the arc :
Arc EFC
Arc CD
Arc DE
And, we know that sum of circular angle is 360 degree.
Arc EFC + Arc CD + Arc DE = 360
If we examine the figure again, we can see that the central angle of an intercepted arc is identical to the arc's measure.
Arc CD is 90 degrees since the central angle is 90 degrees given
Arc DE is 17 degrees
Arc EFC + Arc CD + Arc DE = 360
If we input all the figures
Arc EFC + 90 + 17 = 360
Arc EFC + 107 = 360
Arc EFC = 360 - 107
Arc EFC = 253
Therefore, Arc EFC = 253°

a real estate agent has 12 properties that she shows. she feels that there is a 40% chance of selling any one property during a week. the chance of selling any one property is independent of selling another property. compute the probability of selling more than 5 properties in one week. round your answer to four decimal places.
Answers
The probability of selling more than 5 properties in a week is 0.7494 (rounded to four decimal places).
The probability of selling more than five properties in a week would be calculated using the binomial distribution method. Binomial distribution is used to calculate the probability of an event happening, given a specific number of trials and assuming that each trial is independent of the others. In this case, we want to know the probability of selling more than five properties in a week.
The formula for the probability of selling more than five properties in a week is:
P(X > 5) = 1 - P(X ≤ 5)
Where P is the probability of selling any one property in a week, and X is the number of properties sold in a week.
Using the binomial probability formula, we can determine the probability of selling exactly k properties in one week:
P(X = k) = (n choose k) * p^k * (1-p)^(n-k)
where
n = 12 (total number of properties)
k = number of properties sold
p = 0.40 (probability of selling any one property in a week)
We can now calculate the probability of selling more than 5 properties in a week:
P(X > 5) = 1 - P(X ≤ 5)
P(X > 5) = 1 - (P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5))
P(X > 5) = 1 - [(12 choose 0) * (0.40)^0 * (0.60)^(12-0) + (12 choose 1) * (0.40)^1 * (0.60)^(12-1) + (12 choose 2) * (0.40)^2 * (0.60)^(12-2) + (12 choose 3) * (0.40)^3 * (0.60)^(12-3) + (12 choose 4) * (0.40)^4 * (0.60)^(12-4) + (12 choose 5) * (0.40)^5 * (0.60)^(12-5)]
P(X > 5) = 1 - [0.000015 + 0.0003 + 0.003 + 0.018 + 0.068 + 0.161]
P(X > 5) = 1 - 0.250583
P(X > 5) = 0.749417

Why was southern agriculture economically devastated by the civil war?
southern farmers no longer had enslaved people to work their plantations.
confederate casualties in the civil war outnumbered union casualties.
the north had over twice as many people as the south did.
the federal government encouraged people to move west.
Answers
Southern agriculture was economically devastated by the Civil War primarily because they no longer had enslaved people to work their plantations.
With the abolition of slavery, plantation owners struggled to find laborers who would work for low wages. Additionally, the Confederate casualties outnumbered Union casualties, leaving the South with fewer able-bodied men to work the land. The North, on the other hand, had a larger population and a more diversified economy. Finally, the federal government encouraged people to move west, further reducing the labor supply in the South. As a result, Southern agriculture was left in a state of ruin, with many plantations abandoned or left fallow. This dramatically increased labor costs and reduced production capacity. Additionally, Confederate casualties further depleted the available labor force. The South's smaller population compared to the North also limited its ability to recover. Lastly, the federal government's encouragement of westward expansion attracted potential labor away from the region, further hampering the South's agricultural recovery.

From the given information,
Mr. David gave Ross a number and asked him to divide it by 15.
Let the number be x
That is,
x/15
The quotient and remainder obtained by ross are 341 and 12 respectively
That is,
x/15 = 341 + 12/15
Now, we will solve the equation for x
x/15 = 341 + 12/15
Multiply through by 15
x = 15×341 + 12
x = 5115 + 12
x = 5127

Exercise 1. Two servers (S. and Ss) with exponential service time and same service rate are busy completing service of two jobs at time t = 0. The server that completes service first is referred to as the winning server (Sw), the other is referred to as the losing server (St). Jobs must complete their service before departing from the queue. A) Compute the probability of S to be the winning server, i.e., P(S = S1) = P(S = S2). Compute the probability of S, to be the winning server, i.e., P(S = Sx) = P(S = Si) (pt. 10). B) Compute the expected departure time of the winning server, defined as ty > 0 [pt. 10). C) Compute the expected departure time of the losing server, defined as t > t pt. 10).
Answers
A) Here, we have two servers: Server 1 (S1) and Server 2 (S2). And we need to compute the probability of S to be the winning server, i.e., P(S = S1) = P(S = S2).Since we have two servers with the same service rate, the jobs have equal chances of being assigned to either server.
Therefore, P(S = S1) = P(S = S2)
= 1/2.
(Both servers have equal probabilities of winning).
B) Expected departure time of the winning server, defined as ty > 0. It is also called the mean service time (MST) or the expected value of the service time. The expected value of an exponential distribution is equal to the reciprocal of the service rate. Thus, if the service rate of both servers is μ, then the expected departure time of the winning server will be 1/μ.
C) Expected departure time of the losing server, defined as t > t0. Since the two jobs can't leave until their services are complete, the service time of the winning server will be the total time taken by both jobs. Thus, the expected departure time of the losing server can be calculated by taking the expected departure time of the winning server (which is 1/μ) and subtracting the mean service time (MST) of a single job, which is 1/2μ. Therefore, the expected departure time of the losing server will be 1/μ - 1/2μ = 1/2μ.

convert million gallons per day to cubic feet per second
Answers
The flow rate of 5 MGD is equivalent to 7.73615 cfs
To convert million gallons per day (MGD) to cubic feet per second (cfs), we need to use the conversion factor between the two units. The conversion factor is 1 MGD = 1.54723 cfs.
Therefore, to convert MGD to cfs, we can multiply the given value of MGD by the conversion factor. For example, if we have a flow rate of 5 MGD, we can convert it to cfs as follows:
5 MGD x 1.54723 cfs/MGD = 7.73615 cfs
So, the flow rate of 5 MGD is equivalent to 7.73615 cfs. Similarly, we can convert any given flow rate in MGD to cfs by using the same conversion factor.
It is important to note that these units are commonly used in the context of water supply and distribution systems, where flow rates are a crucial factor in the design and operation of such systems. Therefore, knowing how to convert between different flow rate units is essential for engineers and technicians working in this field.

What is incenter?The incenter of a triangle is the point of intersection of all the three interior angle bisectors of the triangle. This point is equidistant from the sides of a triangle.
Angle ARU = 40 degree
Length of AU = 20
Angle QPA = 35 degree
Since, AR is angle bisector of angle URK.
So, ∠ARU = ∠ARK = 40 degree
Since, incenter point is equidistant from the sides of a triangle.
So, AT = AU = AK = 20
Since, PA is angle bisector of angle QPU.
So, ∠QPA = ∠UPA
3x + 2 = 4x - 9

∠ KLM is an exterior angle of the triangle , then
∠ KLM = ∠ LJK + ∠ JKL , that is
5x - 11 = x + 9 + x - 2
5x - 11 = 2x + 7 ( subtract 2x from both sides )

a lake initially contains 4000 fish. suppose that in the absence of predators or other causes of removal, the fish population increases by 7% each month. however, factoring in all causes, 500 fish are lost each month. how many fish will be in the pond after 8 months? (don't round until the very end.)
Answers
According to calculations made using the provided data, there will be 5557 fish after 8 months.
It is estimated that the lake initially contains 5000 fish.
Since a1 is the population after the first month and the fish population rises by 10% per month while losing 80 fish, it follows that
a1 = ( a0 + 7/100a0) - 500
= (a0 + 0.07a0 ) - 500
=1.07a0 - 500
and ,
a2 = 1.07a0 - 500
Therefore. after eight months, the fish population's recurrence relation will be,
aₙ = 1.07a0 - 500 I (i)
a1 = 1.07( 4000) - 500
= 3780
Similarly,
a2 = 4080
a3 = 4400
a4 = 4111
and
a5 = 1.07( 4621) - 500
= 4444
a6 = 1.07( 4945) - 500
= 4791
a7 = 1.07( 5291) - 500
= 5161
a8 = 1.07( 5661) - 500 = 5557
Thus, there are 5557 fish total after 8 months.
