Answer:

9/f +6

Write 9/f as a fraction.

By using the least-squares regression line the equation will be y = 1.518x + 0.305.

Let us find the value of slope and y-intercept that suits the data y = mx + b

And then , we have to find the value of x² ,∑x,∑y,∑x²,∑xy also N

Then, we have to calculate the slope m

m = n∑(xy) - ∑x ∑y / n ∑(x²) - (∑x)²

= 5 X 236 -26 X 41 / 40 - 676

= 249 / 164

= 1.5183

Then , we hace to calculate the intercept b

b = ∑y - m∑x / n

= 41 - 1.5183 X 26 / 5

= 0.3049

After this we have to assemble it in the equation of line

y =mx + b

Therefore ,

y = 1.518x + 0.305

The correct answer is option D: A line passes through the point (0, 0) and continues through the point (12, 3)

For the first question:

The table shows a proportional relationship between x and y. To describe what the graph of this proportional relationship would look like, we can examine the given data points.

The data points are (12, 3), (8, 26), and (24, ?). We can observe that as x increases, y also increases. This indicates a positive correlation between the variables. Additionally, we can see that the ratio of y to x remains constant for each data point.

Now, let's analyze the answer options:

A. A line passes through the point (0, 0) and continues through the point (3, 12).

This answer option does not align with the given data because there is no data point with an x-value of 3 and a corresponding y-value of 12.

B. A line passes through the point (0, 0) and continues through the point (2, 8).

This answer option aligns with the given data because (2, 8) is a valid data point from the table, and the line passes through the origin (0, 0).

C. A line passes through the point (0, 0) and continues through the point (6, 24).

This answer option does not align with the given data because there is no data point with an x-value of 6 and a corresponding y-value of 24.

D. A line passes through the point (0, 0) and continues through the point (12, 3).

This answer option aligns with the given data because (12, 3) is a valid data point from the table, and the line passes through the origin (0, 0).

Based on the analysis, the correct answer is option D: A line passes through the point (0, 0) and continues through the point (12, 3). This accurately represents the graph of the proportional relationship given in the table.

For the second question, I'm sorry, but you didn't provide the multiple-choice options or the complete question. Could you please provide the question and options so that I can assist you further?

Answer:

Answer: 140

Step-by-step explanation:

The measure of the other arc, say y, enclosed by the two secants can be found by:

\(\frac{1}{2}(30^{\circ}-y^{\circ})=10^{\circ}\\30^{\circ}-y^{\circ}=20^{\circ}\\y=10^{\circ}\)

So the measure of the 30-degree arc, y, and X is 180 degrees (since it's half of the circumference). This means X = 180 - 30 - 10 = 140.

9.  The stamp duty payable on a property with a purchase price of K45,000 is K1,350.

10. The stamp duty payable on a property with a purchase price of K150,000 is K7,500.

To calculate the stamp duty payable on properties with a purchase price of K45,000 and K150,000, we need to apply the corresponding rates of stamp duty based on the given information.

Given:

Value of Property:

Up to K35,000: Stamp Duty Rate - 2%

K35,000 to K70,000: Stamp Duty Rate - 3%

K70,000 to K140,000: Stamp Duty Rate - 4%

Over K140,000: Stamp Duty Rate - 5%

9. Calculate the stamp duty payable on properties whose purchase price is K45,000:

Since the purchase price of K45,000 falls within the range of K35,000 to K70,000, the stamp duty rate applicable is 3%.

Stamp Duty Payable = Purchase Price * Stamp Duty Rate

= K45,000 * 3%

= K45,000 * 0.03

= K1,350

Therefore, the stamp duty payable on a property with a purchase price of K45,000 is K1,350.

10. Calculate the stamp duty payable on properties whose purchase price is K150,000:

Since the purchase price of K150,000 is above K140,000, the stamp duty rate applicable is 5%.

Stamp Duty Payable = Purchase Price * Stamp Duty Rate

= K150,000 * 5%

= K150,000 * 0.05

= K7,500

Therefore, the stamp duty payable on a property with a purchase price of K150,000 is K7,500.

One way to check for a mistake in your work without redoing the cross product is to use the anti- commutative property of the cross product

One property of the cross product is that it is anti-commutative, which means that the order of the vectors matters:

v × w = - (w × v)

Using this property, we can compute w × v and compare it to the result that we got:

w × v = -(2i-j+2k)×(i+2j−3k)

= -2i×i -(-j)×2j + 2k×(-3k)

= -\(2i^2\) -\(2j^2\) -\(6k^2\)

= -2(-1) -2(-1) -6(1)

= 2

Therefore, w × v = 2(-i+2j+3k)

If the result we got, v × w=i+8j−5k, is correct, then we should have:

v × w = - (w × v)

i+8j−5k = -(-i+2j+3k)

i+8j−5k = i-2j-3k

Simplifying this equation, we get:

10j - 8k = 0

This equation is not satisfied by the vector i+8j-5k, so we can say,  that there must be a mistake in our work.

The correct equation of the circle with center (0,0) that passes through the point (-6,-6) is:

(x + 6)² + (y + 6)² = 72

Please note that the equation represents the circle with center (0,0) and radius √72.\(\)

Answer:

The equation of a circle with center (0,0) that passes through the point (-6,-6) is:

(x - 0)² + (y - 0)² = r²

where r is the radius of the circle. Since the center of the circle is (0,0), we can use the distance formula to find the radius:

r = √(0 - (-6))² + (0 - (-6))² = √(6² + 6²) = √72

Therefore, the equation of the circle is:

x² + y² = 72

Answer:

Length of the rectangular lot = 60 meters

Width of the rectangular lot = 30 meters

Step-by-step explanation:

Let the width of the rectangular lot be x meters.

So, Length of the same = 2x metres.

\(A(rectangular \:lot) = (2x)(x)\)

\(\implies A(rectangular \:lot) = 2x^2\)

When length is increasEd by 40 m and width by 6 m. Then....

New length = \((2x + 40) \:m\)

New width =\((x + 6) \:m\)

According to the question:

\((2x + 40)(x + 6) = 2(2x^2)\)

\(\implies 2x(x + 6) + 40(x + 6) - 4x^2=0\)

\(\implies 2x^2+12x + 40x + 240 - 4x^2=0\)

\(\implies 2x^2- 4x^2+12x + 40x + 240 =0\)

\(\implies -2x^2+52x + 240 =0\)

\(\implies 2(x^2-26x - 120) =0\)

\(\implies x^2-26x - 120=0\)

\(\implies x^2-30x+4x - 120=0\)

\(\implies x(x-30)+4(x - 30)=0\)

\(\implies (x-30)(x+4)=0\)

\(\implies x-30=0,\: x+4=0\)

\(\implies x=30,\: x=-4\)

Since, x represents the side length, so its value can't be negative.

\(\implies x=30\)

\(\implies 2x=2(30)=60\)

Thus,

Length of the rectangular lot = 60 meters

Width of the rectangular lot = 30 meters

The square root of 138 lies between 11 and 12, as 11²=121 and 12²=144.

Number is a mathematical object used to count, measure, and label. Numbers are used in almost every field of mathematics and science, including algebra, calculus, geometry, physics, and computer science. Numbers can also be used to represent data, such as population, income, temperature, or time. In addition, numbers are used to represent abstract concepts, such as love, truth, beauty, and justice.

This is because the square root of a number is the number that, when multiplied by itself, produces the original number. Therefore, to find the square root of 138, we need to identify two consecutive integers such that one of them squared is smaller than 138 and the other squared is larger than 138.

To do this, we can work our way up from the integer closer to 0, in this case 11. 11 squared is 121, which is smaller than 138, so we know that the square root of 138 must be between 11 and a larger integer. Then, if we square 12, we get 144, which is larger than 138. Therefore, we can definitively say that the square root of 138 lies between 11 and 12.

Answer:

96.25%

Step-by-step explanation:

The empirical rule regarding mean and standard deviation is that

Therefore between mean and +2 standard deviation or between mean and -2 standard deviation you will find  approximately 95/2 = 47.5% of the values

Between mean and ± 3 standard deviations you will find approximately 97.5/2 = 48.75% of the values

Therefore between 2 standard deviations above and 3 standard deviations below you will find approximately 47.5 + 48.75 = 96.25% of values
