Answer:

The median, mean, and mode of the data set are 5, 4.8, and both 4 and 5 respectively.

Step-by-step explanation:

To find the median of a data set, line up all values from greatest to least and find the number in the center. For example, in the set 1; 2; and 3, 2 would be the median. In this case, the order would be 2, 4, 4, 4, 5, 5, 5, 6, 6, 7. The two numbers in the middle are 5 and 5, their average is 5, so that would be the median. The mean of a data set is the average of all data values in a set. In this case, there are 10 data values, and their total sum is 48, so the mean of this data set is 4.8. The mode of a data set is the value that occurs the most in a set. In this case, 2 occurs once, 4 occurs three times, 5 occurs three times, 6 occurs twice, and 7 occurs once, so the mode of this data set is both 4 and 5.

Answer:

The rate of change is 28.

The correct answer is: O Yes, distance and angle measure are preserved.

When a triangle ABC is reflected across the line y = x, the pre-image and image are congruent.

This is because the line y = x is the perpendicular bisector of the segment joining each corresponding point of the pre-image and image.

Reflection across the line y = x is a type of transformation known as an isometry, which preserves both distance and angle measure.

Here's why:

Distance preservation:

When a point is reflected across the line y = x, the distance between the original point and its reflection remains the same.

This holds true for all corresponding points of the triangle.

Therefore, the distance between any two corresponding points in the pre-image and image triangle will be equal, resulting in distance preservation.

Angle preservation: When a line segment is reflected across the line y = x, the angle between the line segment and the line y = x is preserved. This means that the corresponding angles in the pre-image and image triangle will be congruent.

Since both distance and angle measure are preserved during reflection across the line y = x, the pre-image and image triangles are congruent.

It's important to note that congruence under reflection across a line holds only when the line of reflection is the same for both the pre-image and image.

If the line of reflection were different, the triangles would not be congruent.

It will take approximately 28.67 years for Talwar's investment of R5,800 to grow to R26,100 at a simple interest rate of 12.2% per annum.

To calculate the number of years it will take for Talwar's investment to grow to R26,100 at a simple interest rate of 12.2% per annum, we can use the formula for simple interest:

Simple Interest = Principal × Rate × Time

Given that the principal (P) is R5,800, the rate (R) is 12.2% (or 0.122 as a decimal), and the desired amount (A) is R26,100, we need to find the time (T) it will take. Rearranging the formula, we get:

Time = (Amount - Principal) / (Principal × Rate)

Plugging in the values, we have:

Time = (R26,100 - R5,800) / (R5,800 × 0.122)

= R20,300 / R708.6

≈ 28.67 years

The resistance of 19.0m of the given copper pipe is 1.19 x \(10^{-6}\) ohm.

The resistance of a pipe is given by the formula:

R = (p * L) / (A * n)

where R is the resistance, p is the resistivity of the material (in this case, copper), L is the length of the pipe, A is the cross-sectional area of the pipe, and n is the number of conductors (in this case, 1).

To find the cross-sectional area of the pipe, we first need to find the radius of the pipe. We can do this by taking the difference between the outside diameter and the inside diameter and dividing by 2:

r = (d_outside - d_inside) / 2

r = (5.00 cm - 3.00 cm) / 2

r = 1.00 cm

Now we can find the cross-sectional area of the pipe:

A = pi * \(r^2\)

A = pi * \((1.00 cm)^2\)

A = 3.14

Next, we can use the resistivity of copper, which is 1.68 x\(10^{-8}\) ohm-cm. Now we have all the values required to find the resistance of the pipe:

R = (p * L) / (A * n)

R = (1.68 x \(10^{-8}\) ohm-cm * 19.0 m) / (3.14 \(cm^2\) * 1)

R = (1.68 x \(10^{-8}\) ohm-cm * 19.0 m) / (3.14 \(cm^2\))

R= 1.19 * \(10^{-6}\) ohm

Therefore, the resistance of 19.0m of this pipe is 1.19 x \(10^{-6}\) ohm.

\(K=76\)

Step-by-step explanation:

Starting with a few basic things we know, we know that all of a triangles angles add up to 180.

Therefore, we can set up and solve this equation for \(x\).

\((2x-6)+(x+22)+x=180\)

\(4x+16=180\)

\(4x=164\)

\(x=41\)

By plugging \(x\) back into all of the angles, we can verify that they all do indeed add up to 180.

\((2*41-6)+(41+22)+41=180\)

\((82-6)+(41+22)+41=180\)

\(76+63+41=180\)

\(180=180\)

Knowing that \(x=41\), we can use this information to find K.

\(K=(2x-6)\)

\(K=(2*41-6)\)

\(K=(82-6)\)

\(K=76\)

Answer: 76

Step-by-step explanation:

If you add all the angles they add up to 180

x+ (2x - 6) + (x + 22) = 180      

x+ 2x - 6 + x + 22 = 180                         >Combine like terms

4x + 16 = 180

4x = 164

x = 41

<K = 2x -6

<K = 2(41) - 6

Answer:

1). x = 2.67 units

2). x = 4.80 units

3). x = 6.00 units

Step-by-step explanation:

1). By applying Pythagoras theorem,

 Hypotenuse² = [Leg(1)]² + [leg(2)]²

  12² = x² + b² [Let the base of both the triangles = b units]

  144 = x² + b² ------(1)

  Similarly, 13² = (x + 3)² + b²

  169 = x² + 6x + 9 + b²

  169 - 9 - 6x = x² + b²

  160 - 6x = x² + b² ------(2)

  From equation (1) and (2)

  144 = 160 - 6x

  6x = 160 - 144

  x = \(\frac{16}{6}\)

  x = 2.67 units

2). By applying Pythagoras theorem,

  10² = x² + h² [Let the height of the triangle = h]

  100 = x² + h² ------(1)

  13² = (2x)² + h²

  169 = 4x² + h² -----(2)

  By substituting equation (1) from equation (2),

  169 - 100 = (4x² + h²) - (x² + h²)

  69 = 3x²

  x² = 23

  x = √23

  x = 4.795

  x ≈ 4.80 units

3). By applying Pythagoras theorem,

  9² = x² + h² [Let the height of the triangle = h units]

  81 = x² + h² ------(1)

  7² = (x - 4)² + h²

  49 = x² + 16 - 8x + h²

  49 - 16 = x² + h² - 8x

  33 + 8x = x² + h² -------(2)

  From equation (1) and (2)

  81 = 33 + 8x

  8x = 48

   x = 6.00 units

By making x the subject of the formula in this equation u = cos(0.5x)​ gives x = 2cos⁻¹(u).

In Mathematics and Geometry, an equation can be defined as a mathematical expression which shows that two (2) or more thing are equal. This ultimately implies that, an equation is composed of two (2) expressions that are connected by an equal sign.

In this exercise, you are required to make "x" the subject of the formula in the given mathematical equation by using the following steps.

By taking the arc cosine of both sides of the equation, we have the following:

u = cos(0.5x)

cos⁻¹(u) = 0.5x

By multiplying both sides of the mathematical equation by 2, we have the following:

Here; a = 6, b = 3, and c = -1.

Let's substitute these values into the quadratic formula:

\(x = \frac{-b \±\sqrt{b^2-4ac} }{2a}\\\\ x= \frac{-3 \±\sqrt{3^2-4\ *\ 6\ *\ -1} }{2*6}\\\\x = \frac{-3 \±\sqrt{9+24} }{12}\\\\x = \frac{-3 \±\sqrt{33} }{12}\\\\x = -0.73, \ x=0.23\)

Step-by-step explanation:

To determine which statement is true, we need to compare the number of students who prefer each game relative to the total number of students surveyed.

The total number of students surveyed is:

14 + 16 + 28 + 14 + 8 = 80

A) To find the probability of a student preferring tic tac toe or connect 4 versus checker or jenga, we add the number of students who prefer tic tac toe or connect 4:

28 + 8 = 36

And add the number of students who prefer checker or jenga:

14 + 16 + 14 = 44

Therefore, statement A is false.

B) To find the probability of a student preferring connect 4 versus tic tac toe, we divide the number of students who prefer connect 4 by the number of students who prefer tic tac toe:

28/8 = 3.5

Therefore, statement B is false.

C) To find the probability of a student preferring tic tac toe versus checkers, we divide the number of students who prefer tic tac toe by the number of students who prefer checkers:

8/16 = 0.5

Therefore, statement C is true.

D) To find the probability of a student preferring jenga or tic tac toe versus checkers or bean bag toss, we add the number of students who prefer jenga or tic tac toe:

28 + 8 = 36

And add the number of students who prefer checkers or bean bag toss:

14 + 16 = 30

Therefore, statement D is true.

Therefore, the correct answer is option D: a student is less likely to prefer checkers or bean bag toss than jenga or tic tac toe.
