a. The probability of the system being down in the next hour of operation, if it is initially running, is 0.10.
b. The steady-state probabilities of the system being in the running state (T1) and in the down state (T2) are approximately 0.67 and 0.33, respectively.
a. To find the probability of the system being down in the next hour, refer to the transition probabilities given: From Running to Down = 0.10. So, the probability is 0.10.
b. To find the steady-state probabilities, use the following system of equations:
T1 = 0.80 * T1 + 0.20 * T2
T2 = 0.10 * T1 + 0.90 * T2
And T1 + T2 = 1 (as they are probabilities and must sum up to 1)
By solving these equations, we get T1 ≈ 0.67 and T2 ≈ 0.33 (rounded to two decimal places).
The probability of the system being down in the next hour of operation, if initially running, is 0.10. The steady-state probabilities of the system being in the running state and in the down state are approximately 0.67 and 0.33, respectively.

The price of a suit is reduced by 20%. By what percentage must the reduced price be increased so that the new price is 12% higher than the original price? Show how to use an equation to prove your answer.
Answer:
the reduced price must be increased by 32% to have a 12% higher price than the original price
The percentage that must the reduced in the reduced price so that the new price is 12% higher than the original price is 40%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Let the price of the suit = 100
Reduced = 20%
Now,
The reduced price of the suit.
= 100 - (20% of 100)
= 100 - (20/100 x 100)
= 100 - 20
= 80 _____(1)
Now,
New price.
= 100 + (12% of 100)
= 100 + 12
= 112
Now,
From (1)
100% = 80
Multiply 112/80 on both sides.
112/80 x 100% = 112
140% = 112
This means,
40% increased
Thus,
40% increase in the reduced price.

Answer: 9
Step-by-step explanation:
Endpoint B is (9,4). The slope of AB is 1/3. Point P is 5/6 the directed path of BA.
A is (_,_) and P is (_,_)
P divides BA in the ratio of _:_
Endpoint A has coordinates (3,12) since the slope of AB is 1/3 and B is (9,4). Point P has coordinates (7,8) since P is 5/6 the directed path of BA.
Point P divides BA in the ratio of 5:6.
What is Ratio?How much of one quantity is in the other can be found by comparing two amounts of the same unit and calculating the ratio. Ratios can be categorized into two groups. Part to part ratio is the opposite of part to whole ratio. A two distinct things or groupings are related to one another as shown by the part-to-part ratio. For instance, the boy-to-girl ratio in a class is 12:15, but the part-to-whole ratio describes how one group of people compares to the total population. For instance, five out of ten people say they like to read. The ratio of the part to the whole is therefore 5: 10, which indicates that 5 out of every 10 people enjoy reading.

What does inequality really mean?In mathematics, an inequality is a linear connection or a collection of numbers even when there is no equal sign. Equity always comes after equilibrium. When two numbers are not equal, inequality exists. Between equality and inequality, there exist differences. The most common symbol was chosen because when parameters aren't the same or comparable (). Values can be compared using a variety of disparities, no matter how few or numerous they are. Many fundamental inequality problems can be addressed by flipping the two aspects until only the variables are left

5. Comparing Steelers in the modern NFL, teams emphasize the passing game much more than teams in the 1970s
did, which were more run-oriented. This makes it very difficult to compare the performances of quarterbacks
from these eras - even when they both played for the same team. In 1979, Terry Bradshaw threw for a career-
high 3724 yards. In 2014, Ben Roethlisberger threw for a career-high 4952 yards. 36 Whose performance was
better, relatively speaking?
a. In 1979, the top quarterback for each of the 28 teams threw for an average of 2789 yards with a
standard deviation of 752 yards. Calculate and interpret the z-score for Terry Bradshaw's performance in
1979.
b. In 2014, the top quarterback for each of the 32 teams threw for an average of 3447 yards with a standard
deviation of 970 yards. Calculate and interpret the z-score for Ben Roethlisberger's performance in 2014.k
A z-score is used to measure how many standard deviations an individual value is from the mean of a given set of data.
Whose performance was better, relatively speaking?Terry Bradshaw's performance in 1979 had a z-score of 1.21, which means his performance was 1.21 standard deviations above the mean for all quarterbacks in the NFL that year.Ben Roethlisberger's performance in 2014 had a z-score of 1.31, which means his performance was 1.31 standard deviations above the mean for all quarterbacks in the NFL that year.Terry Bradshaw's performance in 1979 had a z-score of 0.98, which indicates that his performance was slightly above average. This indicates that, while his performance was impressive in 1979, it was still slightly below what other quarterbacks in the league were doing at the time. Ben Roethlisberger's performance in 2014 had a z-score of 1.51, which indicates that his performance was significantly above average. This indicates that his performance was significantly better than what other quarterbacks in the league were doing in 2014. This is a testament to the increased emphasis on the passing game in the modern NFL.To calculate the z-score for Terry Bradshaw's performance in 1979, we subtract the mean of 2789 yards from his performance of 3724 yards and divide by the standard deviation of 752 yards. This yields a z-score of 1.95. This means that his performance was 1.95 standard deviations higher than the average of other quarterbacks in the same year. Similarly, to calculate the z-score for Ben Roethlisberger's performance in 2014, we subtract the mean of 3447 yards from his performance of 4952 yards and divide by the standard deviation of 970 yards. This yields a z-score of 1.63. This means that his performance was 1.63 standard deviations higher than the average of other quarterbacks in the same year. Therefore, while both performances were impressive, Roethlisberger's performance was slightly less impressive than Bradshaw's.To learn more about numerical value refer to:

In a tournament, a professional golfer knows that she is 200 yards from the hole. A spectator is watching her play and is 140 yards away from the golfer. Triangle with vertices labeled golfer and spectator and hole, with the distance from the golfer to the spectator measuring 140 yards and the distance from the golfer to the hole measuring 200 yards and the vertex of the spectator measuring 120 degrees If the spectator has an angle of 120° between the golfer and the hole, what is the angle that the golfer has between the spectator and the hole?
The angle that the golfer has between the spectator and the hole is cos^-1((a^2 + b^2 - c^2)/(2ab))
How do we determine the angle?The angle that the golfer has between the spectator and the hole can be found using the Law of Cosines. The Law of Cosines states that for a triangle with sides a, b, and c and angle C opposite side c, the following equation holds:
c^2 = a^2 + b^2 - 2ab * cos(C)
In this case, we know that a = 140 (the distance from the golfer to the spectator), b = 200 (the distance from the golfer to the hole), and C = 120 (the angle between the golfer and the spectator).
We can use these values to solve for c, which is the distance from the spectator to the hole. Once we have this value, we can use the Law of Cosines again to find the angle between the golfer and the hole.
c^2 = 140^2 + 200^2 - 2 * 140 * 200 * cos(120)
c = sqrt(140^2 + 200^2 - 2 * 140 * 200 * cos(120))
Now we can use this value of c to find angle A:
A = cos^-1((a^2 + b^2 - c^2)/(2ab))
Note that the angle A is what we're looking for, the angle between the golfer and the hole.

What is the additive inverse of 4 /- 7?
For the number -(4 / 7), the additive inverse would be (4 / 7).
The additive inverse of a number is the number that when added to the original number, the result is 0. In other words, it is the opposite of the original number.
To see this, let's add -(4 / 7) and (4 / 7) together:
-(4 / 7) + (4 / 7) = 0
This is because the negative sign in front of the fraction indicates that the fraction is the opposite of (4 / 7). So adding the two fractions together cancels out the opposite and results in 0.
In summary, the additive inverse of -(4 / 7) is (4 / 7) because adding the two fractions together results in 0, which is the definition of an additive inverse.

Recall that a reinforcement beam will extend from one trut to the other when the two trut are 2 feet apart. Algebraically determine the x -value of where the beam hould be placed. (15 point)
The x-value of where the beam should be placed is X = (x1+x2)/2.
Given: the distance between the two trusses is 2 feet and the reinforcement beam will extend from one truss to the other.
We can set up an equation using the distance formula to determine the x-value of where the beam should be placed.
The distance formula is: d = √((x2 - x1)² + (y2 - y1)²)
Let's assume that the trusses are located at point (x1, y1) and (x2, y2) and the beam is located at point (x, y).
We know that the distance between the trusses is 2 feet, so we can set d = 2.
We can use the coordinates of the trusses and the point where the beam is located to set up the equation:
d = √((x2 - x1)² + (y2 - y1)²) = 2
Since the trusses are located on the same line and only the x-coordinate changes, we can assume that y1=y2
Therefore the equation can be simplified to √((x2 - x1)²) = 2
Square both sides: (x2 - x1)² = 4
x2 - x1 = 2
Now we know that the difference between the x-coordinates of the two trusses is 2 feet.
So, to find the x-value of the point where the reinforcement beam should be placed, we can take the average of the x-coordinates of the two trusses.
x = (x1+x2)/2
We don't know the values of x1 and x2, so we can't solve for x. But we know that the reinforcement beam should be placed exactly in the middle of the trusses.
Thus, The x-value of where the beam should be placed is X = (x1+x2)/2.

6. 555 is divisible by three but not by 9: True.
7. 2772 is a multiple of 9 but not of 3: False.
What are the multiplicity rules?A number is divisible by 9 if the sum of the digits of the number is divisible by 9.
6 x 7 = 42 -> not divisible by 9 -> 9 is not a factor of 777,777.
A number is divisible by 3 if the sum of the digits of the number is divisible by 3.
1 + 2 + 3 + 4 + 5 = 15 -> divisible by 3 -> 3 is a factor of 12,345.
A number is a multiple of 5 if it finishes in either 0 or 5. 245+712 finishes in 7, hence it is not a multiple of 5.
3a+15b is divisible by 3 for any values of a and b, as the factors 3 and 15 are both divisible by 3.
11 is a factor of 11³, as:
11³/11 = 11².
As nine is a multiple of 3, all the multiples of 9 are also multiples of 3.

The surface areas for each of the cylinders are;
1) S = 10178.8 millimeters squared
2) S = 955.0 inches squared
3) S = 157.1 centimeters squared
4) S = 351 square inches
How to find the surface area of a cylinder?The formula for surface area of a cylinder is;
S = 2πr² + 2πrh
1) We are given;
radius; r = 30 mm
height; h = 24 mm
Thus;
S = 2π(30)² + 2π(30*24)
S = 10178.8 millimeters squared
2) We are given;
radius; r = 8 in
height; h = 11 in
Thus;
S = 2π(8)² + 2π(8*11)
S = 955.0 inches squared
3) We are given;
radius; r = 1 cm
height; h = 9 cm
Thus;
S = 2π(1)² + 2π(1*9)
S = 157.1 centimeters squared
4) We are given;
radius; r = 4 in
height; h = 10 in
Thus;
S = 2π(4)² + 2π(4*10)
S = 351 square inches
