Assuming that the mechanical properties data given in appendix table a-9 for some carbon steels represents mean values, what is the value of the ultimate tensile strength for 4130 steel quenched and tempered at 400f if a reliability of 90% is required?
The required ultimate tensile strength for 4130 steel quenched and tempered at 400F is 138,000 psi with a reliability of 90 percentage.
The ultimate tensile strength of 4130 steel quenched and tempered at 400F can be calculated using the data given in Appendix Table A-9. First, we need to calculate the standard deviation of the ultimate tensile strength of 4130 steel which is 16,000 psi. Then, we need to calculate the margin of error at a reliability of 90 percentage. This is done by multiplying the standard deviation by 1.645, which gives us a margin of error of 26,120 psi. Finally, we need to add the margin of error to the mean value of ultimate tensile strength, which is 112,000 psi. This gives us a required ultimate tensile strength of 138,120 psi with a reliability of 90%.

3x^2-12x factorise in the form (x+b)(x-b)
Answer:
\(3x(x-4)\)
Step-by-step explanation:
\(3x^2-12x\) cannot be factorised in the form (x+b)(x-b) unless one of the b's is zero, so I wonder if the expression is incomplete?
To factorise \(3x^2-12x\), take out the common factor \(3x\):
\(\implies3x(x-4)\)
Therefore, x = 0 and x = 4
- - - - - - - - -
\(3x^2-12x\) factorised in the form (x+b)(x-b) would be \((3x+0)(x-4)\)
but it is not usual to have a zero in a factorised form.

If P(B)=0.3,P(A∣B)=0.5,P(B ′ )=0.7, and P(A∣B ′ )=0.8, find P(B∣A).
If P(B)=0.3, P(A|B)=0.5, P(B')=0.7and P(A|B')=0.8, then the value of the probability P(B|A)= 0.2113
To find the value of P(B|A), follow these steps:
The probability of B given A can be given by the product of the probability of A given B and the probability of B, divided by the total probability of B. So, the formula for P(B|A) = P(A|B) * P(B) / [P(A|B)*P(B)+P(A|B')*P(B')]. Substituting the values, we get P(B|A) = (0.5) (0.3) / [(0.5) (0.3) + (0.8) (0.7)] ⇒P(B|A) = 0.15 / [0.15 + 0.56] ⇒P(B|A) = 0.15 / 0.71 ⇒P(B|A) = 0.2113. Therefore, P(B|A) = 0.2113.Learn more about probability:

The length of the cut that Franklin made is 100 centimeters.
What is Pythagoras' theorem?
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
The cut that Franklin made is the length of the diagonal of the plywood, which we can find using the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
In this case, the plywood forms a right triangle with sides of length 80 cm and 60 cm. Therefore, the length of the diagonal (the hypotenuse) can be found as follows:
diagonal length = \(\sqrt{(80^2 + 60^2)\)
\(= \sqrt{(6400 + 3600)\)
\(= \sqrt{10000\)
= 100 cm
Therefore, the length of the cut that Franklin made is 100 centimeters.

What is the measure of angle C?

Right triangle A B C, with right angle C B A.
The measure of angle C is 10.39 degrees.In a right triangle, the sum of the measures of the angles is always 90 degrees. Since angle C is opposite the right angle, it is one of the acute angles in the triangle
To find the measure of angle C, we can use trigonometric ratios. In this case, we are not given any side lengths or specific trigonometric functions, so we cannot directly calculate the angle using trigonometry.However, if the angle measures are provided, we can determine the measure of angle C. In the given information, it is stated that the measure of angle C is 10.39 degrees.It is important to note that the measure of angle C in a right triangle can vary depending on the specific triangle's dimensions. In this case, the given measure of 10.39 degrees represents the specific angle C in the given right triangle A B C.In a right triangle, the sum of the angles is always 180°. Since we know that angle C is a right angle (90°), we can find the measure of angle A using the sum of angles property: Angle A = 180° - Angle C - Angle B In this case, Angle B is 90° since it is a right angle. Substituting the values: Angle A = 180° - 90° - Angle C Angle A = 90° - Angle C Now, we can use the fact that the sum of angles in a triangle is 180° to find the measure of Angle C.

The distance s s that an object falls varies directly with the square of time, t t, of the fall. If an object falls 16 16 feet in one second, how long for it to fall 256 256 feet
Answer:
It will take 16 seconds to fall 256 feet.
Step-by-step explanation:
The distance s that an object falls varies directly with the square of time t of the fall i.e.
\(s=kt\)
Where
k is the constant of proportionality
An object falls 16 feet in one second, it means,
16 feet = 1 second
1 feet = (1/16) seconds
To fall 256 feet,
\(t=\dfrac{256}{16}\\\\t=16\ s\)
So, it will take 16 seconds to fall 256 feet.

Using prime notation, the new coordinates after translation are;
New coordinates;
A': (-1, 1)
B': (-1, -2)

what is the length (in cm) of a pendulum that has a period of 0.537 s?
The length of the pendulum is approximately 24.99 cm.
The formula for the period of a pendulum is:
T = 2π√(L/g)
where T is the period in seconds, L is the length of the pendulum in meters, and g is the acceleration due to gravity (approximately 9.81 \(m/s^2\)).
To find the length L of the pendulum in centimeters, we can rearrange the formula as follows:
L = (T/2π\()^2\) * g
Substituting T = 0.537 s and g = 9.81 m/s^2 (which is equivalent to 981 cm/s^2), we get:
L = (0.537/(2π)\()^2\) * 981
L ≈ 24.99 cm
Therefore, the length of the pendulum is approximately 24.99 cm.

Tekan-Tekan Sdn. Bhd. has order for 200 Model AS-120 calculator for delivery on day 200. The calculator consists of three parts. Components 2 and 3 form subassembly 1 . Sub-assembly 1 and component 4 form the final assembly. Following are the work centers and times of each operation. Table Q3(a) shows routine file of the operation. Assuming: - Only one machine is assigned to each operation - The factory works on 8-hour shift, 5 days a week - All parts move in one lot of 200. (a) Illustrate the backward schedule based on the information given above. (12 marks) (b) Identify when component 3 must be started to meet the delivery date. (2 marks)
Component 3 must be started on day 197 to meet the delivery date of day 200.
To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.
(a) Backward schedule:
Operation | Work Center | Time (hours) | Start Day
--------------------------------------------------------
Final Assembly | Work Center 1 | 1 | 200
Sub-assembly 1 | Work Center 2 | 2 | 199
Component 4 | Work Center 3 | 3 | 197
Component 2 | Work Center 4 | 4 | 196
Component 3 | Work Center 5 | 3 | ????
(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.
From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.
Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.
Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

a. Bounded b. geometric c. arithmetic d. diverges
The correct option is a. bounded. According to the question The given sequence is \(\[ a_n = \frac{3}{2n + 1} \]\) is bounded and converges.
We need to determine whether the sequence converges, is bounded, geometric, arithmetic, or diverges.
a. Bounded: To check if the sequence is bounded, we can analyze the behavior of its terms. As n increases, the denominator \(\(2n + 1\)\) also increases. Consequently, the values of \(\(a_n\)\) will approach zero. Since \(\(a_n\)\) approaches zero but is never equal to zero, the sequence is bounded.
b. Geometric: A geometric sequence has a common ratio between consecutive terms. In this case, the sequence does not have a constant ratio between its terms, so it is not geometric.
c. Arithmetic: An arithmetic sequence has a constant difference between consecutive terms. Here, the sequence does not have a constant difference between its terms, so it is not arithmetic.
d. Diverges: Since we have already established that the sequence is bounded and not geometric or arithmetic, we can conclude that the sequence converges. Therefore, it does not diverge.
In summary, the given sequence is bounded and converges.
