Performing a Chi-Square test is a statistical tool used to determine if there is a significant difference between observed and expected data. The test helps to analyze categorical data by comparing observed frequencies to the expected frequencies. The p-value in a Chi-Square test refers to the probability of obtaining the observed results by chance alone.

If a p-value lower than 0.01 is obtained in a Chi-Square test, it means that the results are statistically significant. In other words, there is strong evidence to reject the null hypothesis, which states that there is no significant difference between the observed and expected data. This means that the observed data is not due to chance alone, but rather to some other factor or factors.

The mean, or average, is not directly related to the Chi-Square test or the p-value. The Chi-Square test is specifically used to determine the significance of the observed data. However, the mean can be used as a measure of central tendency for continuous data, but it is not applicable to categorical data.

In conclusion, obtaining a p-value lower than 0.01 in a Chi-Square test means that there is strong evidence to reject the null hypothesis, and that the observed data is statistically significant.

x = 7

Step-by-step explanation:

The 2 right triangles are similar by the AA postulate, then the ratios of corresponding sides are in proportion, that is

\(\frac{x}{4}\) = \(\frac{3.5}{2}\) ( cross- multiply )

2x = 14 ( divide both sides by 2 )

x = 7

Will recommend to see attached picture as name of angles are based on it.

\( \\ \)

We can only find value of x if both triangles i.e triangle DOC and triangle AOB are similar.

\( \\ \)

\(\sf \underline{In \: \triangle \: DOC \: and \: \triangle\:AOB: }\)

\( \\ \)

\( \sf1. \angle DOC = \angle AOB\)

Reason :-

VOC (Vertically opposite angle)

How to recognize either it is VOC (Vertically opposite angle) or not?

So it's basically very easy to recognize, when ever u see lines intersect each other just like a multiply sign ( × ) either horizontal or parallel they are considered as VOC ans are always equal.

\( \\ \)

\( \sf2. \angle CDO = \angle BAO\)

Reason:-

Both are of 90°.

So how we recognized that these both angles were in 90°?

When ever you see that angle is marked in square ( □ ) like shape instead of curve shape then it means the angle is 90°.

\( \\ \)

\(\sf\triangle \: DOC\simeq \triangle\:AOB: \)

By :- AA (angle angle)

\( \\ \\ \)

Now Finally Let's find value of x.

\( \\ \)

\( \dashrightarrow \sf\dfrac{DC}{AB} = \dfrac{OC}{OB} = \dfrac{OD}{OA} \)

Reason :- Corresponding sides of similar triangle are in proportion.

\( \\ \)

So:-

\( \\ \)

\( \dashrightarrow \sf\dfrac{DC}{AB} = \dfrac{OC}{OB}\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{2}{3.5} = \dfrac{4}{x}\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{3.5}{2} = \dfrac{x}{4}\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{35}{2 \times 10} = \dfrac{x}{4}\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{ \cancel{35}}{2 \times \cancel{10}} = \dfrac{x}{4}\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{7}{2 \times 2} = \dfrac{x}{4}\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{4 \times 7}{2 \times 2} = x\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{ \cancel4 \times 7}{\cancel2 \times 2} = x\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{ 2 \times 7}{1 \times 2} = x\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{\cancel 2 \times 7}{1 \times \cancel2} = x\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{1 \times 7}{1 \times 1} = x\)

\( \\ \\ \)

\( \dashrightarrow \sf\dfrac{7}{1 } = x\)

\( \\ \\ \)

\( \dashrightarrow \sf7= x\)

\( \\ \\ \)

\( \dashrightarrow \bf x = 7\)

Question: In a sale, the price of a book is reduced by 25%. The price of the book in the sale is £12. Work out the original price of the book

Answer: £16

Step-by-step explanation:

To determine the original price of the book, we can use the fact that the sale price is 75% (100% - 25%) of the original price. Let's denote the original price as x.

75% of x = £12

To solve for x, we can set up the equation:

0.75x = £12

To isolate x, we divide both sides of the equation by 0.75:

x = £12 / 0.75

x = £16

Therefore, the original price of the book was £16.

Answer:

11.2square feet

Step-by-step explanation:

Area of a sector = theta/360 * πr²

theta is the central angle = 80degrees

radius r = PC = 4ft

Substitute

Area of the sector = 80/360 * 3.14 * 4²

Area of the sector = 80/360 * 3.14 * 16

Area of the sector = 4,019.2/360

Area of the sector = 11.2ft²

Hence tthe area of the blue sector is 11.2square feet

The table that has the correct values for A, B, and C will be:

Step-by-step explanation:

32927372737347599939

Answer:

Step-by-step explanation:

Perimeter of a sector

The circumference of a circle is 2 pi r.

pi = 3.14

r = 21 cm

The angle of this particular sector is 60 degrees.

So the formula for this sector is P = 2*r + 60/360 * 2* pi * r

Now all you need do is plug the numbers in.

P = 2 * 21 + 1/6 * 2 * 3.14 * 21

P = 42 + 21.98

P = 63.98

Area of the sector

Area of a circle = pi * r^2

Area of a sector = theta / 360 * pi * r^2

theta = 60 degrees

area of this sector = (60/360) * 3.14 * 21^2

Area of this sector = (1/6) * 3.14 * 441

Area of this sector = 230.79

\(\bold{\huge{\pink{\underline{ Solution }}}}\)

We have ,

We know that,

[ Perimeter of sector = Arc length + radius + radius ]

\(\bold{\blue{ Perimeter \: of \: Sector = }}{\bold{\blue{\dfrac{\theta}{360°}}}}{\bold{\blue{× 2πr + r + r }}}\)

Subsitute the required values in the above formula :-

Length of the arc of OAB

\(\sf{=}{\sf{\dfrac{ 60°}{360°}}}{\sf{×2πr + 2r }}\)

\(\sf{=}{\sf{\dfrac{ 6}{36}}}{\sf{×2×21π + 2 × 21 }}\)

\(\sf{= }{\sf{\dfrac{1}{6}}}{\sf{ × }}{\sf{\dfrac{22}{7}}}{\sf{× 42 + 42 }}\)

\(\sf{= }{\sf{\dfrac{1}{3}}}{\sf{ × }}{\sf{\dfrac{11}{7}}}{\sf{ × 42 + 42 }}\)

\(\sf{= }{\sf{\dfrac{1}{3}}}{\sf{× 11×6 + 42 }}\)

\(\sf{ = 11 × 2 + 42 }\)

\(\sf{= 22 + 42 }\)

\(\bold{\red{= 64 \: cm}}\)

Thus, The perimeter of the sector OAB is 64 cm

We have to find the area of sector OAB

We know that,

\(\bold{\blue{ Area \: of \: sector = }}{\bold{\blue{\dfrac{\theta}{360°}}}}{\bold{\blue{× πr² }}}\)

Subsitute the required values in the above formula :-

Area of sector OAB

\(\sf{=}{\sf{\dfrac{60°}{360°}}}{\sf{× πr² }}\)

\(\sf{=}{\sf{\dfrac{6}{36}}}{\sf{× π × 21 × 21 }}\)

\(\sf{=}{\sf{\dfrac{1}{6}}}{\sf{× π × 21 × 21 }}\)

\(\sf{=}{\sf{\dfrac{1 }{6}}}{\sf{× 441π}}\)

\(\sf{=}{\sf{\dfrac{1}{6}}}{\sf{× 441 × }}{\sf{\dfrac{22}{7}}}\)

\(\sf{=}{\sf{\dfrac{1}{6}}}{\sf{ × 63 × 22}}\)

\(\sf{=}{\sf{\dfrac{1}{6}}}{\sf{× 1386 }}\)

\(\bold{\red{= 231 \: cm²}}\)

Hence, The area and perimeter of the sector OAB is 64 cm and 231cm²

To find the linear regression line for a set of values, we use the method of least squares to find the line that best fits the data points.

The linear regression line is represented by the equation y = mx + b, where m is the slope of the line and b is the y-intercept. The values of m and b are rounded to two decimal places.

To find the linear regression line, we use a calculator, spreadsheet, or statistical software that can perform regression analysis. We input the given values into the software, and it calculates the values of m and b that minimize the sum of the squared differences between the observed y-values and the predicted y-values on the regression line.

Once the calculations are done, the software provides the values of m and b, rounded to two decimal places. These values represent the slope and y-intercept of the linear regression line, respectively. The resulting equation of the linear regression line is then y = mx + b, where m and b are the calculated values. This line represents the best fit to the given data points and can be used for predicting y-values based on x-values.
