Step-by-step explanation:

The repairs have indeed changed the nature of the output of the machine, with an overall improvement in the quality of the parts produced.

To determine if the repairs have changed the nature of the output of the machine, we can compare the percentages of excellent, good, and unacceptable parts before and after the repairs.

Before repairs:
- 80% excellent
- 16% good
- 4% unacceptable

After repairs, we can calculate the percentages based on the sample of 200 parts:
- 157 excellent parts: (157/200) * 100 = 78.5% excellent
- 42 good parts: (42/200) * 100 = 21% good
- 1 unacceptable part: (1/200) * 100 = 0.5% unacceptable

Comparing these percentages, we can see that the output has changed after the repairs:
- Excellent parts decreased from 80% to 78.5%
- Good parts increased from 16% to 21%
- Unacceptable parts decreased from 4% to 0.5%

The approximate probability that the market will have a proportion of fish with dangerously high levels of mercury that is more than two standard errors above 0.20 is 0.23.

The proportion of fish with high levels of mercury can be found using the formula np and this can be used to find the mean. The standard deviation can be found using the formula sqrt(np(1-p)). With these formulas, the problem can be solved.

The approximate Probability that the market will have a proportion of fish with dangerously high levels of mercury that is more than two standard errors above 0.20:

According to the problem, there are 250 fish that were randomly sampled from the population of edible freshwater fish and the problem asks to find the approximate probability that the market will have a proportion of fish with dangerously high levels of mercury that is more than two standard errors above 0.20.

Let’s first calculate the mean of the proportion of fish with high levels of mercury using the formula np. n = 250 and p = 0.20

np = 250 x 0.20 = 50

The mean is 50.

Let’s now calculate the standard deviation using the formula √(np(1-p)). n = 250 and p = 0.20

Standard deviation =√(250 x 0.20 x (1 - 0.20))

= √(40) = 6.324

Let X be the proportion of fish with high levels of mercury. To find the probability that the market will have a proportion of fish with dangerously high levels of mercury that is more than two standard errors above 0.20, we need to find P(X > 0.20 + 2 x 6.324/250)

P(X > 0.246)

Using the normal distribution table, we find that P(Z > 0.746) = 0.2266 approximately.

Therefore, the approximate probability that the market will have a proportion of fish with dangerously high levels of mercury that is more than two standard errors above 0.20 is 0.23.

(a) To find a nonzero vector orthogonal to the plane through the points P, Q, and R, we can take the cross product of two vectors in the plane.

Let's take vectors PQ and PR. Vector PQ is given by:

PQ = Q - P = (-1, -2, 1) - (1, -4, 5) = (-2, 2, -4)

Similarly, vector PR is given by:

PR = R - P = (4, 1, -3) - (1, -4, 5) = (3, 5, -8)

Taking the cross product of PQ and PR:

N = PQ × PR = (-2, 2, -4) × (3, 5, -8)

Using the cross product formula, we get:

N = (2*(-8) - (-4)*5, -4*3 - (-2)*(-8), (-2)*5 - 2*3)

  = (-16 - (-20), -12 - 16, -10 - 6)

  = (4, -28, -16)

So, a nonzero vector orthogonal to the plane through the points P, Q, and R is (4, -28, -16).

(b) To find the area of the triangle PQR, we can use the magnitude of the cross product of vectors PQ and PR, divided by 2.

The magnitude of the cross product N can be calculated as:

|N| = √(4^2 + (-28)^2 + (-16)^2)

    = √(16 + 784 + 256)

    = √1056

    ≈ 32.50

Therefore, the area of triangle PQR is:

Area = |N|/2

    ≈ 32.50/2

    ≈ 16.25

So, the area of triangle PQR is approximately 16.25 square units.

To calculate the moment of inertia of an object, you need to know its mass and the distance it is from the axis of rotation. In this case, the object has a mass of 12 kg and is distributed 4 meters from the axis of rotation. The formula to calculate the moment of inertia is I = mr^2, where the moment of inertia, m is the mass, and r is the distance from the axis of rotation.

Using this formula, we can calculate the moment of inertia of the object:

I = 12 kg x (4 m)^2

I = 192 kgm^2

Therefore, the moment of inertia of the object is 192 kgm^2.
To calculate the moment of inertia for an object, you can use the following formula:

Moment of Inertia (I) = Mass (m) × Distance² (r²)

Given the object's mass is 12 kg and the mass is distributed 4 meters from the axis of rotation, we can plug these values into the formula:

I = 12 kg × (4 m)²

Now, we'll square the distance:

I = 12 kg × 16 m²

Finally, multiply the mass and the squared distance:

I = 192 kg·m²

So, the moment of inertia of the object is 192 kg·m².

To determine the sign of the sum of two integers when one integer is positive and the other is negative, we can follow a simple rule based on their magnitudes.

If the magnitude of the positive integer is greater than the magnitude of the negative integer, the sum will be positive. This is because the positive integer outweighs the negative integer, resulting in a positive value.

On the other hand, if the magnitude of the negative integer is greater than the magnitude of the positive integer, the sum will be negative. In this case, the negative integer dominates and determines the sign of the sum.

In both scenarios, the sign of the larger magnitude integer takes precedence and determines the sign of the sum. It is important to note that the sum will always have the sign of the integer with the larger magnitude, regardless of the specific values of the integers involved.

By considering the magnitudes of the integers, we can easily determine the sign of their sum when one integer is positive and the other is negative.

Answer:

  (x, y) = (3, -7)

Step-by-step explanation:

You want to solve these equations, -x+y=-10 and 3x+4y=-19, using elimination.

The "elimination" method of solving a system of equations combines the equations in such a way that one of the variables is eliminated. Here, we can eliminate the x-variable by adding 3 times the first equation to the second:

  3(-x+y) +(3x+4y) = 3(-10) +(-19)

  7y = -49 . . . . . . . . . simplify; note x is eliminated from the equation

  y = -7 . . . . . . . . . . . divide by 7

The value of x can be found from the first equation by substituting for y:

  -x +(-7) = -10

  x = 10 -7 = 3 . . . . . . . add x+10 to both sides

The solution to these equations is (x, y) = (3, -7).

The solution is x=3, y = -7

From the question, we have

-x+y=-10 ...........(i)

3x+4y=-19 ..............(ii)

Multiplying equations (i) by 3, we get

-3x+3y=-30................(iii)

Adding both the equation (ii) and (iii), we get,

3x+4y-3x+3y  = -19-30

⇒7y = -49

⇒y = -7

Substituting the value of y in equation (i), we get

-x+y=-10

⇒-x-7=-10

⇒x=3

Elimination Method:

One method for resolving a system of linear equations is the elimination method. In this approach, the equation in one variable is obtained by either adding or subtracting the equations. We can add the equation to delete a variable if its coefficients are the same and have the opposite sign from the other variables. Similar to this, we can subtract the equation to get the equation in one variable if the coefficients of one of the variables are the same and their signs are the same.

This is my working out, I used the balance method

Answer:

B. \(\frac{RY}{RS}\) = \(\frac{RX}{RT}\) = \(\frac{XY}{TS}\), must be true.

Step-by-step explanation:

Similar figures are figures whose angles and sides are similar with respect to a definite ratio when compared.

From the given question, note that ΔRXY is within ΔRST. Given that the two triangles are similar, then their sides can be compare in a form of ratio as:

\(\frac{RY}{RS}\) = \(\frac{RX}{RT}\) = \(\frac{XY}{TS}\)

Therefore by comparing the length of sides of the triangles, option B must be true.

The dimensions of one of two triangles that are similar can be obtained

from the other triangle by multiplying by a scale factor.

Reasons:

The given relationship between the triangles are;

Line XY is drawn within ΔRST to form ΔRYX.

XY is parallel to ST

Given that we have;

Point X on side RT and point Y on side RS of ΔRST

ΔRST is similar to ΔRYX, we get;

The ratio of the corresponding sides are equal, which gives;

\(\displaystyle \frac{RY}{RS} = \frac{RX}{RT} = \frac{XY}{TS}\)

Therefore;

The option that gives the statement that must be true is; \(\displaystyle \underline{\frac{RY}{RS} = \frac{RX}{RT} = \frac{XY}{TS}}\)

The system is consistent since it has an infinite number of solutions.

*There is at least one row of the coefficient matrix that does not have a pivot position. This means the augmented matrix, which will have the form 0 000 0 o 0 0, so the system is consistent.

A coefficient matrix is a matrix that contains the coefficients of the variables in the linear equations of a system.

An augmented matrix is a matrix that contains the coefficient matrix's column and the constant vector's column.The system of equations has a unique solution if there is one pivot column for each row in the coefficient matrix.

In this case, a row echelon form can be used to convert the coefficient matrix. The augmented matrix will be used to identify whether a system of equations is consistent.

Suppose a 5 x 8 coefficient matrix for a system has five pivot columns. Then there is at least one row of the coefficient matrix that does not have a pivot position, as stated in option D. This implies that in the row echelon form of the coefficient matrix, there will be at least one row with zeros, indicating that there are an infinite number of solutions to the system.Therefore, the system is consistent since it has an infinite number of solutions.
