The value of the segment FE for the similar triangles is equal to 6.
How to calculate for FE for the similar trianglesThe triangles EFG and ECD are similar, this implies that the length FE of the smaller triangle is similar to the length CE of the larger triangle
and the length FG of the smaller triangle is similar to the length CD of the larger triangle
so;
FE/12= 6/2FE
2(FE)² = 12 × 6 {cross multiplication}
2(FE)² = 72
(FE)² = 72/2
(FE)² = 36
FE = √36 {take square root of both sides}
FE = 6.
Therefore, the value of the segment FE for the similar triangles is equal to 6.

assume z is a standard normal random variable. then p(1.41 < z < 2.85) equals . a. .4772 b. .3413 c. .8285 d. .0771
Answers
The value of P(1.41 < Z < 2.85) is 0.0771.
Hence, the correct answer is d.
A normally distributed random variable with mean μ= 0 and standard deviation σ= 1 is referred to as a standard normal random variable. The letter Z will always be used to represent it.
Because the Standard Normal Distribution is a probability distribution, the area under the curve between two points indicates the likelihood that variables will take on a range of values.
The whole area under the curve is one, or one hundred percent.
The mean and variance of a normal distribution are governed by two factors.
A standard normal distribution is a normal distribution with a mean of 0 and a standard deviation of 1.
The probability that a standard normal random variable Z is between 1.41 and 2.85 can be found using a standard normal table with a standard normal cumulative distribution function.
The answer is approximate:
P(1.41 < Z < 2.85)
= P(Z < 2.85) - P(Z < 1.41)
= 0.9927 - 0.9185
= 0.0742

A and B and C are three villages on a highway. The distance between A and B is 18km. A motorbiker moved from A at speed of 10km/hr. At the same time , another man at village B started moving at 4km/hr. How long does it take the motorbiker to catch up to the man ? If they both reach C at the same time then what is the distance between C and B.
Answers
Answer:
Let A B = x miles = 18
B C = y miles
t1 = (18 + y) / 10 time for biker 1 to reach C
t2 = y / 4 = y / 4
t1 = t2 both bikers reach C at same time
(18 + y) / 10 = y / 4
72 + 4 y = 10 y
y = 12 distance from B to C
Check:
A C = 12 + 18 = 30 km
t1 = (18 + 12) / 10 = 3 hr
t2 = 12 / 4 = 3 hrs
So both meet at C in 3 hrs

Capacity is very expensive, so it is run at high utilization. There is a lot of variability in arrivals and processing times. Waiting or throughput times are long for this process.
Gaining understanding of the trade-offs operations managers must make is a major contribution of OR/MS models. One such trade-off concerns capacity, inventory, and variability: while the firm would want to function at 100% capacity utilization with very no inventory and tolerate high levels of unpredictability, this is not realistic.
The trade-off between these three competing goals is demonstrated and clarified using the conventional G/G/1 queueing paradigm. This insight can be described as a relationship between capacity, inventory, and the third parameter of information in situations where greater information can be used to lessen the variability in services or in arrivals (rather than variability).
Adopting the terminology of Lovejoy (1998), this inter- relationship is referred to as the OM triangle. Finding her company's ideal location in relation to the OM triangle is the manager's responsibility, as was mentioned in this article.
With variable arrival and processing times, there is a long wait period. It should have high utilization because of expensive capacity.

the geometric series $a ar ar^2 \cdots$ has a sum of $12$, and the terms involving odd powers of $r$ have a sum of $5.$ what is $r$?
Answers
The sum of an infinite geometric series is given by a+ar+ar^2 where a is the first term and r is the common ratio.
The sum of the series can be represented by :
a / ( 1 - r) = 12
a = 12 ( 1- r ) (1)
So....note that the sum of the terms with odd powers of r can be represented by :
ar + ar^3 + ar^5 + ar^7 + ..... + ar^(2n - 1) = 5 (2)
And note that the sum of the terms with even powers of r can be represented by :
a + ar^2 + ar^4 + ar^6 + ar^8 + ..... + ar^(2n) = 7 (3)
Multiply (2) by r on both sides
ar^2 + ar^4 + ar^6 + ar^8 + ..... + ar^(2n ) = 5r (4)
Subtract (4) from (3)
a = 7 - 5r (5)
Sub (5) into (1)
7 - 5r = 12(1 - r)
7 - 5r = 12 - 12r
7r = 5 → r = 5/7
Check
a = 7 - 5(5/7) = 24/7
a / ( 1 - r) =

To solve this problem, we can set up an equation by considering the value of nickels and dimes. By solving the equation, we can find the number of nickels and the number of dimes.
Explanation:Let's assume the number of nickels as x.
The value of nickels is 0.05x dollars.
The number of dimes is stated as '5 more than twice the number of nickels,' which can be expressed as (2x + 5) dimes.
The value of dimes is 0.10(2x + 5) dollars.
Since the total value of the coins is $3.00, we can set up the equation:
0.05x + 0.10(2x + 5) = 3.00

Time taken to have both planes at same altitude = 1.2 seconds.
What is relative speed?Relative speed can be defined as the speed of a moving body with respect to another. When two bodies move in the same direction, their relative speed is computed by their difference. But when two bodies are moving in the opposite direction, the relative speed is calculated by adding the speed of both the bodies.
Given,
Plane A is at altitude of 3329 feet.
Plane B is at altitude of 4000 feet
Plane A is gaining altitude at Distance between them
= 4000 - 3329 feet
= 671 feet
Speed of plane A = 605 feet per second.
Speed of plane B = 45.25 feet per second
Since both plane are moving upwards
Relative speed = 605 - 45.25 = 559.75 feet per second
Time of both planes to be on same altitude

Number of players = 3
number of times game is repeated = 4
P( any person wins a game ) = 1/3
P ( any person does not win a game ) = 1 - 1/3 = 2/3
P ( any person wins no game in 4 attempts ) = ( 2/3 )^4 = 16/81
Note : each player has equal chance of winning
Find the probability that there is at least one person who wins no games
lets represent the probability of each player not wining a game with alphabet A
A1 = player 1 wins no game
A2 = player 2 wins no game
A3 = players 3 wins no game
Applying the inclusion-exclusion formula
P( A1 ∪ A2 U A3 ) = P(A1 ) + P(A2) + P(A3) - P( A1 ∩ A2 ) - P( A2 ∩ A3 ) - P( A1 ∩ A3 ) + P( A1 ∩ A2 ∩ A3 )

P ( A1 wins all games in 4 attempts ) = ( 1/3 )^4 = 1/81
P( A1 ∩ A2 ∩ A3 ) = P ( no players wins any game in 4 attempts ) = 0

(give the full number.) c. what is the range? (give the full number.) d. what is the standard deviation? (give the full number.)
Answers
a. The number of passengers for each cruise line in thousands:
4,133,000 passengers ÷ 1,000 = 4,133 passengers
2,369,000 passengers ÷ 1,000 = 2,369 passengers
1,295,000 passengers ÷ 1,000 = 1,295 passengers
928,000 passengers ÷ 1,000 = 928 passengers
679,000 passengers ÷ 1,000 = 679 passengers
So, the answer is 4,133; 2,369; 1,295; 928; 679.
b. The mean number of passengers can be found by adding the number of passengers for each cruise line and then dividing the total by the number of cruise lines, which is 5.
(4,133 + 2,369 + 1,295 + 928 + 679) ÷ 5 = 10,514 ÷ 5 = 2,102.8 passengers
So, the mean number of passengers is 2,102.8 passengers.
c. The range is the difference between the highest and lowest number of passengers, which is:
4,133 - 679 = 3,454 passengers
So, the range is 3,454 passengers.
d. The standard deviation can be calculated using the formula for the standard deviation of a sample. However, this calculation is quite complex and requires a significant amount of mathematical knowledge and computational resources. Without access to those resources, the standard deviation cannot be calculated
The standard deviation is a measure of the amount of variation or dispersion from the mean. It shows how spread out the values in a set of data are. To calculate the standard deviation, the difference of each value from the mean is squared and then divided by the number of items in the set. The standard deviation provides a way to quantify the degree of variation of the values around the mean. It is a useful tool for understanding how much each value in a set deviates from the average.

Answers
The correct option is A) No, because the center of a distribution and the spread are not related
How standard deviation depend on the value of the mean?The standard deviation is a measure of the spread or dispersion of a set of data. It is not directly related to the mean or average of the data.
The standard deviation is calculated based on the deviations of each data point from the mean, taking into account how many data points there are.
The mean does not affect the calculation of the standard deviation, as the formula for standard deviation is based solely on the data itself and not on any summary statistics like the mean.
The value of the standard deviation can remain the same even if the mean changes, and conversely, the mean can change without affecting the standard deviation.
Thus, option A) No, because the center of a distribution and the spread are not related is correct.

how many \textbf{nm} are there in 4.6 x 10^{-4} \textbf{m}? enter the appropriate exponent as a number and not a word.
Answers
There are 4.6×10⁵ nanometer present in "4.6×10⁻⁴ meter " .
The Unit nanometer (nm) is a very small unit of length measurement, used to measure the size of particles, proteins, and other small objects.
One meter is equivalent to 10⁹ nanometers, so converting from meters to nanometers is done by multiplying by 10⁹ .
To convert 4.6 × 10⁻⁴ meters to nanometers, we simply need to multiply the value by 10⁹ :
⇒ (4.6 × 10⁻⁴ meters)×(10⁹ nanometers/meter)
⇒ 46,000 nanometers = 4.6×10⁵ nanometers .
Therefore, 4.6×10⁻⁴ meter is equivalent to 4.6×10⁵ nanometers .

a scientist is studying bacteria whose cell population doubles at constant intervals, at which times each cell in the population divides simultaneously. four hours from now, immediately after the population doubles, the scientist will destroy the entire sample. how many cells will the population contain when the bacteria is destroyed?
Answers
Since the cell population doubles at constant intervals, we can use the formula for exponential growth: N = N0 * 2^(t/k), where N0 is the initial population, t is the time elapsed, and k is the doubling time.
Since we are told that the population will double four hours from now, and since we are not given the initial population or the doubling time, we cannot determine the final population when the bacteria will be destroyed.
As the division two hours ago and the division just now, the population quadrupled that is two doubling periods, so each doubling period is about an hour.

please solve for x.....
Answers
The values of x in the circles and secant lines are 2.3, 4 and 1
How to determine the values of xTo calculate x, we make use of the tangent-secant line theorem which stated that
c² = b * d
Using the above as a guide, we have the following:
Shape (10)
(14 + x + 2) * 14 = 16^2
This gives
16 + x = 18.3
Collect and evaluate the like terms
x = 2.3
Shape (11)
(4x + 9) * 9 = 15^2
This gives
4x + 9 = 25
Collect and evaluate the like terms
x = 4
Shape (12)
x * (x + 8) = 3^2
This gives
x^2 + 8x - 9 = 0
Factorize
(x + 9)(x - 1) = 0
So, we have
x = -9 and x = 1
x = -9 is invalid
Hence, the value is 1
