Paul is solving for x. He shows his work as follows:
Step 1: 3x + 2 = 7x - 2
Step 2: 2 = 4x - 2
Step 3: 4 = 4x
Step 4: X = 1
When Paul checks his answer, he thinks he’s made a mistake At which step did Paul make a mistake?
Answer:
This is correct
Step-by-step explanation:
Paul has made no mistakes but he probably is wondering if the 4x that he got in the equation is correct. He might second guess that he shouldn't have subtracted the 3x from the 7x but instead divided the two numbers.

THE PICTURE IS FOR QUESTION 4
Answer:
3. B. P = 134x + 20y
4. J. (10, 150), I(40, 120), G(60, 100), C(60, 0) and E(10, 0)
5. C. 60 mopeds 100 bicycles
Step-by-step explanation:
3. The given information are;
The number of mopeds the company must produce per month = 10
The number of mopeds the company can produce month = 60
The number of bicycles the company can produce per month = 120
The total sum of the produced mopeds and bicycles ≤ 160
The profit on a moped = $134
The profit on a bicycle = $20
Given that the number of moped produced = x and the number of bicycles produced = y
Therefore, we have;
Profit, P = $134 × x + $20 × y
Which gives;
B. P = 134x + 20y
4) From Desmos, using the following constraints;
x + y ≤ 160
10 ≤ x ≤ 60
0 ≤ y ≤ 120 we have;
The vertices of the constraint for the feasible region are;
J. (10, 150), I(40, 120), G(60, 100), C(60, 0) and E(10, 0)
5) We note that since the profit from each moped is more than the profit from the sale of each bicycle, the maximum possible number of moped should be produced, while the rest should be used to produce bicycles
Therefore, given that from the vertices, the maximum possible number of moped = 60, the number of bicycles to be produced should be 160 - 60 = 100 bicycles
Which gives;
C. 60 mopeds 100 bicycles.
3. The objective function should be option B. P = 134x + 20y
4. The vertices of the feasible region, given the constraints should be J(10, 150), I(40, 120), G(60, 100), C(60, 0) and E(10, 0)
5. The number of each product that should be manufactured per month should be option C. 60 mopeds 100 bicycles
Objective function, vertices, and number of each product:3.
Here we assume that the number of mopeds produced = x
and the number of bicycles produced = y
So, the profit equation should be
Profit, P = $134 × x + $20 × y
That provides P = 134x + 20y
4) From Desmos, we used the following constraints;
x + y ≤ 160
10 ≤ x ≤ 60
0 ≤ y ≤ 120 we have;
So, The vertices of the constraint should be
J. (10, 150), I(40, 120), G(60, 100), C(60, 0) and E(10, 0)
5) The maximum no of mopeds should be 60
And, the no of bicycles that need to be produced is
= 160 - 60
= 100 bicycles
That provides 60 mopeds 100 bicycles.

The number of bacteria growing in an incubation culture increases with time according to B() 9800 (3)x, where x is time in days. After how many days will the number of bacteria in the culture be 7,144,200?
After approximately 2.4744 days, the number of bacteria in the culture will reach 7,144,200.
To find the number of days (x) after which the number of bacteria in the culture reaches 7,144,200, we need to solve the equation B(x) = 7,144,200.
The given equation for the growth of bacteria is B(x) = 9800(3)^x.
Setting B(x) equal to 7,144,200, we have:
9800(3)^x = 7,144,200
To solve for x, we can take the logarithm of both sides using base 3 logarithm:
log₃(9800(3)^x) = log₃(7,144,200)
Using logarithmic properties, we can simplify the equation:
log₃(9800) + log₃(3)^x = log₃(7,144,200)
Since log₃(3)^x is equivalent to x (since log₃(3) = 1), we can rewrite the equation as:
log₃(9800) + x = log₃(7,144,200)
Now, we can solve for x by isolating it:
x = log₃(7,144,200) - log₃(9800)
Using a calculator, we can compute the values:
x ≈ 5.2456 - 2.7712
x ≈ 2.4744

In this question, you will build a matrix from the eigenvectors and eigenvalues, instead of the other way around. The matrix A has three eigenvalues: >1 = 8 with eigenvector u₁ = (1,1,0), 12 = -3 with eigenvector u2 = (1,-1, 1) and 13 = 12 with eigenvector uz (1,-1,-2). (a) Normalize the eigenvectors u; to give vi. Enter them in the usual format e.g. [1,2,3]. = 01: v2 = = v3 (b) Recall that you can build an orthogonal matrix P whose columns are that set of orthonormal eigenvectors. Then PT AP D, where D is a diagonal matrix that contains the eigenvalues along the diagonal. We now have P and D, so can find A from the formula A = PDPT. Enter the matrix A as a list of row vectors.
To construct the matrix A using eigenvectors and eigenvalues, we normalize the given eigenvectors to obtain orthonormal vectors. We then form an orthogonal matrix P by arranging the orthonormal eigenvectors as columns. Next, we create a diagonal matrix D with the eigenvalues along the diagonal. Finally, we compute A using the formula A = PDPT.
(a) To normalize the eigenvectors, we divide each vector by its magnitude to obtain unit vectors. The normalized eigenvectors are:
v₁ = [1/√2, 1/√2, 0]
v₂ = [1/√3, -1/√3, 1/√3]
v₃ = [1/√6, -1/√6, -2/√6]
(b) To construct the matrix A, we form an orthogonal matrix P using the orthonormal eigenvectors as columns:
P = [v₁, v₂, v₃] = [[1/√2, 1/√3, 1/√6], [1/√2, -1/√3, -1/√6], [0, 1/√3, -2/√6]]
Next, we create a diagonal matrix D with the eigenvalues along the diagonal:
D = diag, -3, 12])
Finally, we compute A using the formula A = PDPT:
A = PDPT = [[1/√2, 1/√3, 1/√6], [1/√2, -1/√3, -1/√6], [0, 1/√3, -2/√6]] diag([8, -3, 12]) [[1/√2, 1/√3, 1/√6].T, [1/√2, -1/√3, -1/√6].T, [0, 1/√3, -2/√6].T]
Performing the matrix multiplication, we obtain the matrix A:
A = [[4, 0, 0], [0, -1, 0], [0, 0, 12]]
Therefore, the matrix A, constructed using the given eigenvectors and eigenvalues, is:
A = [[4, 0, 0], [0, -1, 0], [0, 0, 12]]

96;100
To calculate the mean of a data set, we need to sum up all the values and then divide by the total number of values.
Sum of the data set = 33 + 42 + 49 + 49 + 53 + 55 + 55 + 61 + 63 + 67 + 68 + 68 + 69 + 69 + 72 + 73 + 74 + 78 + 80 + 83 + 88 + 88 + 88 + 90 + 92 + 94 + 94 + 94 + 94 + 96 + 100
Count of values = 31
Mean = (Sum of the data set) / (Count of values)
Now we can substitute the values and calculate:
Mean = (33 + 42 + 49 + 49 + 53 + 55 + 55 + 61 + 63 + 67 + 68 + 68 + 69 + 69 + 72 + 73 + 74 + 78 + 80 + 83 + 88 + 88 + 88 + 90 + 92 + 94 + 94 + 94 + 94 + 96 + 100) / 31

Subtract ¾ from 5/6

if you dont know how to find lowest common multiple by prime factorisation, you can make the common denominator 6x4 instead which is 24, so

===========================================================
Explanation:
The given set is in roster notation. Think of a baseball or football team (or any sports team) how their roster lists out all of the players. In this case, each number is like a player.
The idea here is to simplify the set so we don't have to write out every single item. Instead we have a rule to make things a bit simpler.
In this case, the set {7, 8, 9, 10, 11, 12, 13, 14} describes all natural numbers from 7 to 14
This means we can say {x | x is a natural number with 6 < x < 15}
Note how the endpoints x = 6 and x = 15 are not included. This is because there isn't a "or equal to" as part of the inequality sign. Sure enough 6 and 15 are not part of the original set.
An equivalent set would be [tex]\{ x | \text{ x is a natural number with } \ 7 \le x \le 14\}[/tex] and here we have "or equal to" involved. For this example, the endpoints x = 7 and x = 14 are included.
--------------
Something like choice A and choice D are not complete answers because we don't know if x is a whole number, natural number, rational number, real number, etc. If x was say a real number, then x = 10.75 would be involved with choice A. But 10.75 is not part of the original set.
