Please help me with question 25. And please include an explanation.

The answer is D) Smaller  Set B's standard deviation is expected to be smaller than Set A's due to its tighter range.

To determine whether Set A's standard deviation is smaller, larger, or about the same as Set B's, we can analyze the spread of the values in each set. The standard deviation measures the dispersion or variability of a data set.

Looking at Set A, we can see that the values range from 1 to 25, with a progression that is relatively spread out. On the other hand, Set B has values ranging from 9 to 18, with a more limited range.

Based on this observation, we can infer that Set B's values are more tightly grouped together compared to Set A. Consequently, Set B is expected to have a smaller standard deviation since the values are less dispersed around the mean.

Therefore, the answer is D) Smaller. Set B's standard deviation is likely to be smaller than Set A's. However, to precisely determine the standard deviations and compare them, it would be necessary to calculate the actual values using the formulas for standard deviation or use statistical software.

The equation of line AC in the form ax + by + c = 0, where a, b, and c are integers, is:

5x + y - 3 = 0.

To determine the equation of line AC in the form ax + by + c = 0, where a, b, and c are integers, we need to find the coordinates of point C.

Since triangle ABC is right-angled at point A, we know that the slope of line BC[tex](m_{BC})[/tex] multiplied by the slope of line AC [tex](m_{AC})[/tex]  is equal to -1 (because the two lines are perpendicular to each other).

The equation of line BC is given as 5y - x = 15.

By rearranging it in the form y = mx + b, we can determine its slope.

The slope of BC[tex](m_{BC})[/tex] is 5.

Using the perpendicularity condition, we have:

[tex]m_{BC} \times m_{AC} = -1[/tex]

[tex]5\times m_{AC} = -1[/tex]

[tex]m_{AC} = -1/5[/tex]

Now, let's find the coordinates of point C.

We have the coordinates of points A and B, so we can find the slope between points A and C using the formula:

[tex]m_{AC} = (N - (-2)) / (m - 1)[/tex]

-1/5 = (N + 2) / (m - 1)

Cross-multiplying, we get:

-5(m - 1) = N + 2

-5m + 5 = N + 2

-5m - N = -3

Rearranging this equation, we obtain:

5m + N = 3

Step-by-step explanation:

In terms of length, 218 inches is greater than 6 yards.

To determine which is more, 6 yards or 218 inches, we need to convert one or both of the measurements to a common unit of measurement. In this case, we can convert yards to inches or inches to yards for comparison.

Since there are 36 inches in a yard, we can convert 6 yards to inches by multiplying it by 36:

6 yards * 36 inches/yard = 216 inches.

Now, we can compare the converted measurements: 216 inches and 218 inches.

Since 218 inches is greater than 216 inches, we can conclude that 218 inches is more than 6 yards.

This comparison can also be verified by considering the conversion factors. 6 yards is equivalent to 216 inches, which is smaller than 218 inches.

It is important to note that when comparing measurements, it is crucial to ensure that both measurements are in the same unit for an accurate comparison. Converting them to a common unit helps provide a clear understanding of which value is greater or smaller.

The value of a/b is 10/3.

We start by simplifying the expression under the square root:

√((4/5) * (5/4) * (6/5) * (x/a) * (b/x)) = 2

We can observe that the terms (4/5) and (5/4) cancel out, leaving us with:

√(6/5 * (x/a) * (b/x)) = 2

Next, we square both sides of the equation to eliminate the square root:

6/5 * (x/a) * (b/x) = 2²

Simplifying the right hand side, we get:

6/5 * (x/a) * (b/x) = 4

Multiplying both sides by 5/6, we get:

(x/a) * (b/x) = (5/6) * 4

x and b cancel out, and we are left with:

a = 10/3

Therefore, the value of a/b is:

a/b = (10/3) / 1

a/b = 10/3

The analysis above, graph (B) best represents the function g(x) = 3^(2x-1) as it demonstrates the expected exponential growth behavior as x increases.

The function g(x) = 3^(2x-1) is an exponential function with a base of 3. In this case, the base is raised to the power of (2x-1).

To determine the behavior of the function, we can analyze the exponent (2x-1).

When x is a positive number, 2x-1 will increase as x increases. This means that the function will experience exponential growth as x increases.

When x is a negative number, 2x-1 will decrease as x decreases. This indicates that the function will exhibit exponential decay as x decreases.

Now, let's analyze the options to identify the graph that best represents the function g(x).

Graph (A): This graph shows exponential decay. As x increases, the function decreases. However, the rate of decay seems to be slower than what we would expect for the given function g(x)=3^(2x-1). Therefore, graph (A) does not accurately represent the given function.

Graph (B): This graph shows exponential growth. As x increases, the function increases. The rate of growth appears to match the behavior we would expect for the function g(x)=3^(2x-1). Therefore, graph (B) is a potential candidate.

Graph (C): This graph shows exponential decay. As x increases, the function decreases. However, the rate of decay seems to be faster than what we would expect for the given function g(x)=3^(2x-1). Therefore, graph (C) does not accurately represent the given function.

Considering the analysis above, graph (B) best represents the function g(x) = 3^(2x-1) as it demonstrates the expected exponential growth behavior as x increases.

The midpoint of segment YZ is (-a, -2b).

Given the coordinates of the rhombus WXYZ:

W(0, 4b)

X(2a, 0)

Y(0, -4b)

Z(-2a, 0)

The midpoint formula is given by:

Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)

Substituting the coordinates of Y and Z:

Midpoint of YZ = ((0 + (-2a)) / 2, (-4b + 0) / 2)

= (-a, -2b)

Therefore, the midpoint of segment YZ is (-a, -2b).

To demonstrate that the segments joining the midpoints of the rhombus are perpendicular, we need to prove that the slopes of these segments are negative reciprocals of each other.

Let's consider the segments joining the midpoints:

Segment joining the midpoints of WX and YZ:

Midpoint of WX: ((0 + 2a) / 2, (4b + 0) / 2) = (a, 2b)

Midpoint of YZ: (-a, -2b)

Slope of WX = (2b - 4b) / (a - 0) = -2b / a

Slope of YZ = (-2b - (-4b)) / (-a - 0) = 2b / a

The slopes of WX and YZ are negative reciprocals of each other, indicating that these segments are perpendicular.

We have shown that the segments joining the midpoints of a rhombus are perpendicular to each other and have equal lengths. Therefore, these segments form a rectangle.

Additionally, the midpoint of segment YZ is (-a, -2b).

The yearly installment that Thabo has to pay to the bank is c. R202.

We shall use the formula for calculating the amortized loan payment to estimate the yearly installment that Thabo has to pay to the bank:

Installment = (Loan amount (L) * Interest rate (I)) / (1 - (1 + Interest rate)^(-Number of years (N))):

In short: Installment = (L * I) / (1 - (1 + I)⁽⁻ⁿ⁾)

Given:

L = R700

I = 6% = 0.06

N = 4

Plugging the values into the formula, we have the yearly installment:

Installment = (700 * 0.06) / (1 - (1 + 0.06)⁽⁻⁴⁾)

= 42/(1 - (1 + 0.06)⁽⁻⁴⁾ )

= 42/ (1 - (1.06)⁽⁻⁴⁾ )

= 42/(1 - 0.792)

= 42 / 0.2079 ≈ 202.01

A = 139°

B = 139°

You can see A and B are coefficients of each other, which means they have the same angle because they are opposite each other on the straight line. just like the two 41° angles are.

The angle around a point always add up to 360°, so add the 41° angles.

41 + 41 = 82°

Then minus this by 360°.

360 - 82 = 278°

And to work out one angle, which gives you the angle for both, divide 278 by two.

278 ÷ 2 = 139°

Both A and B have an angle of 139°

Example:

To find the value of two intersecting lines, you need to know the equations of both lines. Then, you can set the equations equal to each other and solve for the variable x. This will give you the x-coordinate of the point where the lines intersect. To find the y-coordinate, you can plug the value of x into either equation and solve for y. For example, if one line is y = 3x - 5 and another line is y = -2x + 7, then you can set 3x - 5 = -2x + 7 and solve for x:

3x - 5 = -2x + 7

5x = 12

x = 12/5

Then, plug x = 12/5 into either equation and solve for y:

y = 3(12/5) - 5

y = 36/5 - 25/5

y = 11/5

Therefore, the point of intersection is (12/5, 11/5).

If one of the lines has a given angle, such as 41 degrees, then you can use trigonometry to find its equation. For example, if one line passes through the origin and has an angle of 41 degrees with the positive x-axis, then you can use the slope formula to find its equation:

slope = tan(41 degrees) ≈ 0.87

y = mx + b

y = 0.87x + 0

Then, you can use the same method as before to find the point of intersection with another line.

If each bus holds ten students and there are three buses, then the total number of students going to the show is 10 x 3 = 30 students.

The mass of the bus, 1900, is most likely measured in kilograms (kg) because kilograms are a commonly used unit for measuring the mass of large objects like vehicles.

If there are five rows in the theatre and Mr. Murray wants an equal number of students to sit in each row, then the number of students in each row would be the total number of students (30) divided by the number of rows (5), which is 30 / 5 = 6 students per row.

Answer:

[tex]f=\frac{N^2-H}{6}[/tex]

Step-by-step explanation:

[tex]N^2=6f+H\\\mathrm{or,\ }6f=N^2-H\\\mathrm{or,\ }f=\frac{N^2-H}{6}[/tex]

Step-by-step explanation:

I'm assuming the sides can only be integers.

The most optimal area would be a square. We need to distribute 800 to 3 sides, which of course is not possible with integers. We will have to distribute the 800 as evenly as possible.

800/3 = 266.666666667.

We can let 2 sides be 267 and 1 side be 266. This will distribute it evenly. However, notices that the river side can be any length. Meaning that we can make one side be 268 and the other 2 sides be 266. This still satisfies our 800 feet of fencing, while being larger than 267 * 266.

Shorter side: 266 ft

Longer side: 268 ft

Greatest Possible Area: 71288
