Statement Reason
4d = 1/3(c - d) Given
12d = c - d Multiplication property
13d = c Addition property
c = 13d Symmetric property
Explanation:
The initial equation is
4d = 1/3(c - d)
Then, we need to multiply both sides by 3, so
3(4d) = 3(1/3)(c-d)
12d = c - d
Finally, add d to both sides of the equation
12d + d = c - d + d
13d = c
Then,
c = 13d
Therefore, the answer is
Statement Reason
4d = 1/3(c - d) Given
12d = c - d Multiplication property
13d = c Addition property
c = 13d Symmetric property

area of a trapizium is 84m².its pararrell sides are 12m and 9m. find its hiegh
Answer:
8m
Step-by-step explanation:
We can convert the trapezium into a rectangle to make finding the area easier.
Say that the top side is 9m, and that the bottom side is 12m.
12 - 9 = 3
3/2* = 1.5
*Note that we are dividing by two to get the "overhang" of the bottom side.
Now that we have our overhang, we can find the length of the "t-rect"**.
**"T-rect" refers to a rectangle that has been formed by changing a trapezium into a rectangle.
12 - 1.5 = 10.5
9 + 1.5 = 10.5
The length of the t-rect is 10.5.
84/10.5 = 8
The height of the t-rect is 8m.
Since the height of the original trapezium is equal to the height of the t-rect***,
***Since we have only adjusted the length
this also means that 8m would also be the height of the original trapezium.
Now, there is a second way of doing this.
Find the median of 12 and 9.
9, 10, 11, 12
10, 11
The median is 10.5.
84/10.5 = 8
You get the same answer. These methods could be used as a solve-then-check method to another problem like these.

when is stochastic gradient descent preferred over deterministic gradient descent
Stochastic Gradient Descent is that it does the calculations faster than gradient descent and batch gradient descent that is where stochastic gradient descent preferred over deterministic gradient descent.
One of the most widely used techniques for selecting the model that best fits the training data is gradient descent. Typically, that model is the one that minimizes the loss function, such as in a linear regression by minimizing the Residual Sum of Squares. Stochastic Gradient Descent is a variation on gradient descent that is stochastic, or probabilistic. It performs significantly better in large datasets and fixes Gradient Descent's flaws. It is therefore frequently employed as the optimization algorithm in extensive, online machine learning techniques like Deep Learning. SGD is a method of generalization outside of the training set and is an extension of the gradient descent algorithm.

y=−2x+8
Answer:
y = 2x - 2
Step-by-step explanation:
Answer:
y= 2x -2
Step-by-step explanation:
x + 2y= 16
1.) rearrange the formula in the form y=mx + c
x + 2y = 16(subtract x on both sides)
2y = 16-x(divide by 2 on both side)
y = 8 - x/2

Neglect a is constructive response to job satisfaction. True False
Neglect a is constructive response to job satisfaction is the false statement.
Neglect is not a constructive response to job satisfaction. It refers to a situation where employees feel ignored, unappreciated, or unsupported in their work, which can negatively impact their job satisfaction. Constructive responses to job satisfaction involve addressing concerns, providing support, and promoting a positive work environment.
Job satisfaction refers to an individual's level of contentment and fulfillment with their job. It is influenced by various factors such as work environment, compensation, relationships with colleagues, opportunities for growth, and alignment with personal values.
When employees experience job dissatisfaction, they may respond in different ways. One possible response is neglect, which refers to a passive and disengaged attitude towards work. Neglectful employees may become indifferent, withdraw their effort, or mentally check out from their responsibilities.

Answer:
The answer is that the ball was in the air for 0.56 seconds when it was 54 feet above the ground. This was determined by using the Quadratic Formula to solve the equation 54 = -16s^2 + 96s for the variable s.
Step-by-step explanation:
To solve this equation, we can use the Quadratic Formula, which states that for a quadratic equation in the form ax^2 + bx + c = 0, the solutions are given by:
x = (-b +/- sqrt(b^2 - 4ac)) / (2a)
In this case, a = -16, b = 96, and c = -54. Plugging these values into the Quadratic Formula, we get:
s = (-96 +/- sqrt(96^2 - 4 * -16 * -54)) / (2 * -16)
= (96 +/- sqrt(9216 + 4352)) / -32
= (96 +/- sqrt(13,568)) / -32
Since we want the time (in seconds) that the ball was in the air, we need to find the positive solution to this equation. Thus, we have:
s = (96 + sqrt(13,568)) / -32
= (96 + 120) / -32
= 0.5625 seconds
Rounding this value to the nearest hundredth of a second, we get 0.56 seconds. This means that the ball was in the air for 0.56 seconds when it was 54 feet above the ground.
To solve this equation, we used the Quadratic Formula. This method allowed us to find the time (in seconds) that the ball was in the air by solving for the value of the variable s in the given equation. This helped Vue answer his question by providing a numerical value for the amount of time that the ball was in the air when it was 54 feet above the ground.
Prove that if a sequence (a n

If a sequence (aₙ) is convergent, then either there exists k such that aₖ = sup{aₙ | n ∈ N} or there exists k such that aₖ = inf{aₙ | n ∈ N}, or both.
The sequence (aₙ) is convergent, and let L be its limit. We want to show that one of the following two cases must hold:
Case 1: There exists k such that aₖ = sup{aₙ | n ∈ N}.
Suppose this is not the case. Then for every k, there exists a term in the sequence, denoted by aₖ, that is greater than sup{aₙ | n ∈ N}. Since (aₙ) is convergent and L is its limit, there exists an N such that for all n > N, |aₙ - L| < |aₖ - L|. However, this contradicts the assumption that aₖ is greater than sup{aₙ | n ∈ N}. Therefore, there must exist a k such that aₖ = sup{aₙ | n ∈ N}.
Case 2: There exists k such that aₖ = inf{aₙ | n ∈ N}.
Similarly, assume that this is not the case. Then for every k, there exists a term in the sequence, denoted by aₖ, that is smaller than inf{aₙ | n ∈ N}. Since (aₙ) is convergent and L is its limit, there exists an N such that for all n > N, |aₙ - L| < |aₖ - L|. However, this contradicts the assumption that aₖ is smaller than inf{aₙ | n ∈ N}. Therefore, there must exist a k such that aₖ = inf{aₙ | n ∈ N}.
Hence, if a sequence is convergent, there either exists k such that aₖ = sup{aₙ | n ∈ N} or there exists k such that aₖ = inf{aₙ | n ∈ N}, or both.

The keys 12,18,13,2,3,23,5 and 15 are inserted into an initially empty hash table of length 10 using open addressing with hash function h(k)=k mod 10 and quadratic probing. What is the resultant hash table? 3.(2 pts) Insert the keys 79, 69, 98, 82, 14, 72, 59 into the Hash Table of size 13. Resolve all collisions using Double Hashing where the first hash-function is h(k)=kmod13 and second hashfunction is g(k)=1+(kmod11) ? The required probe sequences are given by: i
∗
probe =(h(k)+i
∗
g(k))mod TableSize
To determine the resultant hash table using open addressing with quadratic probing, let's go through the steps for each key:
1. Initialize an empty hash table of length 10.
2. Insert the first key, 12, into the hash table. Since h(12) = 12 mod 10 = 2, and the slot at index 2 is empty, we place 12 there.
3. Insert the next key, 18. Since h(18) = 18 mod 10 = 8, and the slot at index 8 is empty, we place 18 there.
4. Insert 13. Since h(13) = 13 mod 10 = 3, and the slot at index 3 is empty, we place 13 there.
5. Insert 2. Since h(2) = 2 mod 10 = 2, and the slot at index 2 is already occupied by 12, we perform quadratic probing to find the next available slot. We start at index 2 and probe using the sequence: 2, 5, 10, 17, 26, ... The next available slot is at index 5, so we place 2 there.
6. Insert 3. Since h(3) = 3 mod 10 = 3, and the slot at index 3 is already occupied by 13, we perform quadratic probing. We start at index 3 and probe using the sequence: 3, 6, 11, 18, 27, ... The next available slot is at index 6, so we place 3 there.
7. Insert 23. Since h(23) = 23 mod 10 = 3, and the slot at index 3 is already occupied by 13, we perform quadratic probing. We start at index 3 and probe using the sequence: 3, 6, 11, 18, 27, ... The next available slot is at index 11, so we place 23 there.
8. Insert 5. Since h(5) = 5 mod 10 = 5, and the slot at index 5 is already occupied by 2, we perform quadratic probing. We start at index 5 and probe using the sequence: 5, 8, 13, 20, 29, ... The next available slot is at index 8, so we place 5 there.
9. Insert 15. Since h(15) = 15 mod 10 = 5, and the slot at index 5 is already occupied by 2, we perform quadratic probing. We start at index 5 and probe using the sequence: 5, 8, 13, 20, 29, ... The next available slot is at index 13, but since the hash table has a length of 10, we wrap around to index 3 and continue probing. The next available slot is at index 0, so we place 15 there.
The resultant hash table after inserting all the keys using open addressing with quadratic probing is:
Index: 0 1 2 3 4 5 6 7 8 9
Value: 15 12 18 13 23 5
Now let's move on to the second part of your question. We need to insert keys into a hash table of size 13 using double hashing, with the first hash function h(k) = k mod 13 and the second hash function g(k) = 1 + (k mod 11). We'll resolve collisions by probing using the sequence i * g
(k), where i starts from 0 and increments by 1 for each probe.
1. Initialize an empty hash table of size 13.
2. Insert the key 79. Since h(79) = 79 mod 13 = 11, and the slot at index 11 is empty, we place 79 there.
3. Insert 69. Since h(69) = 69 mod 13 = 4, and the slot at index 4 is empty, we place 69 there.
4. Insert 98. Since h(98) = 98 mod 13 = 12, and the slot at index 12 is empty, we place 98 there.
5. Insert 82. Since h(82) = 82 mod 13 = 9, and the slot at index 9 is empty, we place 82 there.
6. Insert 14. Since h(14) = 14 mod 13 = 1, and the slot at index 1 is empty, we place 14 there.
7. Insert 72. Since h(72) = 72 mod 13 = 10, and the slot at index 10 is empty, we place 72 there.
8. Insert 59. Since h(59) = 59 mod 13 = 10, and the slot at index 10 is already occupied by 72, we perform double hashing probing. Using g(59) = 1 + (59 mod 11) = 1 + 4 = 5, we probe using the sequence: 0, 5, 10, 15, ... The next available slot is at index 15 % 13 = 2, so we place 59 there.
The resultant hash table after inserting all the keys using double hashing is:
Index: 0 1 2 3 4 5 6 7 8 9 10 11 12

As each trial has a 0.375 probability, the probability for three successes is 0.05273 and for six successes is 0.00278.
What is probability?Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, if we are unclear of how an event will turn out. Statistics is the study of occurrences subject to probability. The number of possible outcomes is divided by the total number of possible outcomes to determine probability. Odds are not the same as probability. Odds are calculated by dividing the probability of a given event by the probability that it won't. By dividing the number of preferable outcomes by the total number of potential outcomes, probability, which measures the likelihood that an event will occur, is obtained.
Here,
The probability of success in each trial=3/8
For 3 success,
P(3)=(3/8)³

Dylan is at a water park getting ready to go down a water slide. The slide is 150 feet long and the ladder to the top of the slide is 58 feet high. To the nearest tenth of a foot, find the distance from the bottom of the slide to the bottom of the ladder.
The distance from the bottom of the slide to the bottom of the ladder is approximately 160.9 feet.
We can use the Pythagorean theorem to find the distance from the bottom of the slide to the bottom of the ladder. 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 other two sides. In this case, the hypotenuse is the distance we want to find, and the other two sides are the length of the slide (150 feet) and the height of the ladder (58 feet). Therefore, we have:
Distance² = 150² + 58²
Distance²= 22,500 + 3,364
Distance² = 25,864
Taking the square root of both sides, we get:
Distance = 160.9 feet (rounded to the nearest tenth)
Therefore, the distance from the bottom of the slide to the bottom of the ladder is approximately 160.9 feet.

For one solution,2x + 9 + 3x + x = 15
For infinitely many solutions,2x + 9 + 3x + x = 6x + 9
Based on the given conditions,
(1) No solutions :
There will be no solutions when the left side is inconsistent with the right side:
2x + 9 + 3x + x = _ x + _
We can sum of difference,
6x + 9 = 6x
Subtract 6x from both sides,
6x - 6x = -9
9 = 0
9 = 0 which is absurd and hence the equation has no solution.
(2) One solutions :
There will be one solution when the left side and right side are not inconsistent and not the same.
2x + 9 + 3x + x = 15
6x + 9 = 15
Subtract 9 from both sides.
6x = 6
Divide both sides by 6.
x = 1 and this is the only solution.
(3) Infinity solutions :
There will be an infinite number of solutions when the equation is true for any value of x. This will be the case when the left side and right side are identical.
2x + 9 + 3x + x = 6x + 9
6x + 9 = 6x + 9
Subtract 6x from both sides,
9 = 9, both sides are balanced which means, the equation has infinitely many solutions.
Therefore,
For no solution,2x + 9 + 3x + x = 6x
For one solution,2x + 9 + 3x + x = 15

Step-by-step explanation:
Step 1:
First of all find the determinate.
Cross multiply the number 11 ✖ -1
detA = 11 × -1= -11 ---eq1
And now cross multiply the number 3 ✖ - 5
detA = 3 × -5= -15 ---eq2
Now we use eq 1 and 2
detA = (-11)-(-15)
Minus cancels minus
So it becomes
detA = -11 + 15
= 4
Step 2:
We find adjacent of the given.
[11 -5]
adjA= [ ]
[3 -1 ]
We change the places. The number 11 goes to in place of -1. -1 goes in place of 11.
And we change the signs of -5 and 3. -5 becomes 5 and 3 becomes -3.
We get
[-1 5]
adjA = [ ]
