Answer:

x = -12 and x = 12.

Step-by-step explanation:

To solve for x, we need to take the square root of both sides of the equation:

x² = 144

√(x²) = √144

since sqaure root gives both positive and neagtive value, so

x = ±12

So the solutions for x are x = -12 and x = 12.

System of linear equation have no solutions both when both the lines are parallel(not intersecting or coincident).

Percy is wrong since system will have no solution for any real numbers except k = 7, because at k = 7, both lines become same, thus having infinite solutions.

When both the lines(represented by both the equations) are parallel and not coincident, then that system of linear equations have no solutions as there is no common point on both line.

If they are coincident(lying over each other), then there will have infinite solution since in that case, they will have infinite points in common.

Thus, if two lines are not in any of above case, they intersect at single point and in that case, the considered system of equation has unique single solution.

The first equation is

this can be rewritten as:

\(6x + 4y = 14\\ \\ \text{Dividing by 2 on both sides}\\ \\ 3x + 2y = 7\)

Writing in slope-intercept form:
\(3x + 2y = 7\\ 2y = 7-3x\\\\ y = -\dfrac{3}{2}x + \dfrac{7}{2}\)

The second equation is

\(3x + 2y =k\)

If k = 7, then both equation become same thus infinite solution.

\(3x + 2y = k\\ 2y = k - 3x\\\\ y = \dfrac{k}{2} -\dfrac{3}{2}x\\\\ y = -\dfrac{3}{2}x +\dfrac{k}{2}\)

If k is not 7, then the y intercept  of both the lines will be different but slope will be same. The same slope denotes lines are  parallel and different y-intercept shows that the lines are not same(not coincident).

Thus, there are infinite solutions for all values of k except 7.

Thus, Percy is wrong since system will have no solution for any real numbers except k = 7, because at k = 7, both lines become same, thus having infinite solutions.

The amount that the customer be charged before tax and tip is $25.55

Given,

The markup on a restaurant = 250%

The cost of a meal to produce = $7.30

We have to find the amount will the customer be charged before tax and tip;

The markup price = 250/100 × 7.30 = 5/2 × 7.30 = 2.5 × 7.30 = 18.25

The Markup price on a restaurant is $18.25

Now,

The amount that the customer be charged before tax and tip = The cost of a meal to produce + The markup price

= 7.30 + 18.25

= 25.55

That is,

The amount that the customer be charged before tax and tip is $25.55

Yes, you can show significant differences using superscripts in an ANOVA (Analysis of Variance) single-factor test.

In an ANOVA test, superscripts are commonly used to indicate significant differences between the means of different groups or treatments.

Typically, letters or symbols are assigned as superscripts to denote which groups have significantly different means. These superscripts are usually presented adjacent to the mean values in tables or figures.

The specific superscripts assigned to the means depend on the statistical analysis software or convention being used. Each group or treatment with a different superscript is considered significantly different from groups with different superscripts. On the other hand, groups with the same superscript are not significantly different from each other.

By including superscripts, you can visually highlight and communicate the significant differences between groups or treatments in an ANOVA single-factor test, making it easier to interpret the results and identify which groups have statistically distinct means.

The given statement "An algorithm is a calculation that determines how long it will take to solve a problem." is False.

An algorithm is not just a calculation that determines how long it will take to solve a problem. An algorithm is a step-by-step set of instructions or a process used to solve a problem or perform a specific task. It is a systematic approach that allows a computer or human to break down a problem into smaller, manageable parts and reach a solution effectively.

Algorithms are the foundation of computer programming and can be applied in various fields such as mathematics, data processing, and problem-solving. They can be simple, like finding the largest number in a list, or complex, like solving a Rubik's Cube.

Efficiency is a key factor in evaluating algorithms. The time and resources required for an algorithm to solve a problem can vary greatly depending on the method used. However, the primary purpose of an algorithm is to provide a clear and concise procedure to reach a solution, rather than just estimating the time needed to solve a problem.

In summary, an algorithm is a well-defined process designed to perform a specific task or solve a problem, rather than just calculating the time required to do so. Its effectiveness depends on its efficiency, accuracy, and the simplicity of the steps involved.

The predicted number of runs for the player with 149 hits is roughly 81 runs. The predicted number of runs for the player with 86 hits is roughly 43 runs.

To calculate this, you can use a linear regression equation which is R = (H*b) +a, where R is the predicted number of runs, H is the number of hits, b is the slope of the line, and a is the intercept.

Using the above formula, we can say that:

R= (81*149) - 80*(149)

= 81.

Similarly for 2nd part:

R= (43*86) - 85*43

= 43.

The matrix [0 3 7] is not diagonalizable.

The matrix [0 3 7] is not diagonalizable. Diagonalization is a process in linear algebra that transforms a matrix into a diagonal form using eigenvectors. To determine if a matrix is diagonalizable, we need to find its eigenvalues and eigenvectors. In this case, the matrix [0 3 7] has a single eigenvalue of zero, but it lacks additional linearly independent eigenvectors. Diagonalizable matrices require a complete set of linearly independent eigenvectors. Without these additional eigenvectors, the matrix cannot be diagonalized. Diagonalizable matrices are desirable as they simplify calculations and reveal important properties of the system they represent.

The volume of the solid generated by revolving the region in the first quadrant bounded by the coordinate axes is V = π∫ln 8eˣdx,

The volume of a solid generated by revolving a region about a line is calculated by using the method of slices.

In this case, we have a region in the first quadrant bounded by the coordinate axes, the curve y = eˣ and the line x = ln 8, which is being revolved about the line x = ln 8.

To find the volume of this solid, we need to take slices perpendicular to the line of rotation and calculate the area of each slice.

The volume can then be calculated by multiplying the area of each slice by its corresponding distance from the line of rotation and summing up the results.

The volume of this solid is calculated by the equation

=> V = π∫ln 8eˣdx,

Answer:

Step-by-step explanation:

To find the missing numbers in the table, we need to calculate the number of items and the cost of each item for the missing row.

Let the missing row be for boots.

Boots

Cost of each (£)

Number bought

Total cost (£)

To find the cost of each pair of boots, we need to divide the cost of the known items (gumshields, headguards, shoulder pads) by the corresponding number of items bought and then take the average.

The total number of gumshields, headguards, and shoulder pads bought is:

7 + 10 = 17

The total cost of the gumshields, headguards, and shoulder pads is:

£194.85 + £149.90 = £344.75

The cost of each pair of boots can be calculated as follows:

Cost of each pair of boots = (Total cost of gumshields, headguards, and shoulder pads) / (Total number of gumshields, headguards, and shoulder pads)

Cost of each pair of boots = £344.75 / 17

Cost of each pair of boots = £20.28 (rounded to two decimal places)

To find the number of pairs of boots bought, we can divide the total cost of all items (£2006) by the cost of each pair of boots (£20.28):

Number of pairs of boots = Total cost / Cost of each pair of boots

Number of pairs of boots = £2006 / £20.28

Number of pairs of boots = 98.8

Therefore, the missing numbers in the table are:

Boots

Cost of each (£)

20.28

Number bought

A) The area of parallelogram 1 is 4 square units greater than the area of parallelogram 2.

The area of parallelogram 1 is 2 square units greater than the area of parallelogram. Option 2 is correct.

The space filled by a flat form or the surface of an item is known as the area.

The number of unit squares that cover the surface of a closed-form is the figure's area. Square centimeters and other similar units are used to measure area.

A₁ is the area of parallelogram 1

A₁ is the area of parallelogram 2

l₁ is the distance between the points (2,6),(0,2)

l₂ is the distance between the points (4,0)(0,2)

b₁ is the distance between the points (2,0),(0,-2)

b₂ is the distance between the points (2,6),(4,-6)

A₁ =  l₁ × b₁

A₁=4.47 ×4.47

A₁  = 19.89 sq.unit

A₂=l₂×b₂

A₂=2.82 × 6.342

A₂=17.88 sq.unit

A₁-A₂ = 19.89 sq.unit - 17.88  sq.unit'

A₁-A₂= 2.01

The area of parallelogram 1 is 2 square units greater than the area of a parallelogram.

Hence,option 2 is correct.
