Standardize every test score from Mr. Bowman's class, the new mean would be 0, the new standard deviation would be 1, and the shape of the distribution would remain the same as before.

Let's first understand what standardizing means.
Standardizing test scores involves transforming the original scores to a new scale, called z-scores.

This process is done by subtracting the mean (average) score from each test score and dividing the result by the standard deviation of the scores. The formula for finding the z-score is:
z = (X - μ) / σ
X is the original test score, μ is the mean, and σ is the standard deviation.
Now, let's discuss the properties of the standardized scores:
New mean:

Standardize the test scores, the new mean (average) of the z-scores will always be 0.

This occurs because we subtract the mean from each test score, making the sum of the differences equal to 0.
New standard deviation:

After standardization, the standard deviation of the z-scores will always be 1.

This is because we divide each score by the original standard deviation, results in the new standard deviation being equal to 1.
Shape of the distribution:

The shape of the distribution (i.e., the pattern of the scores) will not be affected by standardization.

If the original scores followed a bell-shaped curve, the standardized scores would maintain the same bell shape.

The measure of acute angle is π/7

The area of a sector of a circle is a fraction of the circle's total area, proportional to the measure of the central angle that subtends the sector.

The formula to calculate the area of a sector of a circle is:

=> A = (θ/360) × πr²

Where: A is the area of the sector

θ is the measure of the central angle in degrees

r is the radius of the circle

We can use this formula to calculate the area of the sector in the given problem

Here we have

Two distinct lines pass through the center of three concentric circles of radii 3, 2, and 1. The area of the shaded region in the diagram is 8/13 of the area of the unshaded region.

Let the area of the shaded part is 'S' and 'U' be the area of the unshaded part and the acute angle formed by the two lines be 'θ'

Hence, we can take => S + U = 9π

From the data, S = 8/13 U

=> 8/13 U + U = 9π

=>  21/13 U = 9π

=> 9π = 21/13 U

=> U = 117/21 π

=> U = 39π/7  and S = 24π/7

Now write the area of the shaded region in terms of θ

=> 2θ/2π · π + 2(π - θ)/2π (4π - π) + 2θ/2π (9π - 4π) = 24π/7

=> θ + 3π - 3θ + 5θ = 24π/7

=> 3θ + 3π = 24π/7  

=> 3θ = 24π/7 - 3

=> 3θ = 24π - 21π/7

=> 3θ = 3π/7  

=>  θ = π/7

Consider any such n-digit sequence. There are two cases to consider for the leftmost digit:

The leftmost digit is 0: In this case, we can append any valid (n-1)-digit sequence to the right, which gives us f(n-1)possibilities.

The leftmost digit is 2: In this case: f(n)=f(n−1)+f(n−2)as the second digit must be 0 (since no 1 can appear to the right of any 2). After the second digit, we can append any valid (n-2)-digit sequence to the right, which gives us[tex]$f(n-2)$[/tex] possibilities.

Answer:The number line should look like this:

<-----o----->

-3

Step-by-step explanation:

To solve the inequality x - 2 ≤ -5, we can follow these steps:

Add 2 to both sides of the inequality to isolate x on one side:

x - 2 + 2 ≤ -5 + 2

x ≤ -3

The solution to the inequality is x ≤ -3, which means that x is less than or equal to -3.

To plot the solution on a number line, we can place a closed dot on -3 to represent the "less than or equal to" condition, indicating that -3 is included in the solution set.

The number line should look like this:

<-----o----->

The closed dot on -3 indicates that -3 is included in the solution set.

Answer:

Part A:

The price of product A is determined by the function f(x) = 12500(0.82)^x. To determine whether the price is increasing or decreasing, we can look at the behavior of the function as x increases.

When x increases by 1 year, the value of the function is:

f(x+1) = 12500(0.82)^(x+1) = 10250(0.82)^x

To find the percentage change in price per year, we can calculate:

[(f(x+1) - f(x)) / f(x)] * 100%

= [(10250(0.82)^x - 12500(0.82)^x) / 12500(0.82)^x] * 100%

= -0.16 * 100%

= -16%

Therefore, the price of product A is decreasing by 16% per year.

Part B:

To determine which product recorded a greater percentage change in price over the previous year, we need to calculate the percentage change in price for each product from year to year.

For product B, the percentage change in price from year to year is:

   From year 1 to year 2: [(f(2) - f(1)) / f(1)] * 100% = [(3136 - 5600) / 5600] * 100% = -43.14%

   From year 2 to year 3: [(f(3) - f(2)) / f(2)] * 100% = [(1756.16 - 3136) / 3136] * 100% = -44.06%

   From year 3 to year 4: [(f(4) - f(3)) / f(3)] * 100% = [(983.45 - 1756.16) / 1756.16] * 100% = -43.99%

For product A, we already determined that the percentage change in price per year is -16%.

Therefore, product A recorded a smaller percentage change in price over the previous year compared to product B.

Town A is 8km far  apart from Town B.

Speed is measured as the ratio of distance to the time in which the distance was covered which does not give direction.

The formula = Distance/Time

How to determine this

Let d represent the distance covered

And let t represent the time covered

First,

To calculate the distance covered by the cyclist and Joggers

The cyclist and joggers travel the total distance at t hour

Distance = Speed * Time

The cyclist travels at 14t km

And Joggers at 10t km

So, d = 14t +10t

d = 24t

Then, the Cyclist meet the Jogger in 4 minutes i.e 4/60 hours = 1/15 hours and t + 1/15 until the cyclist meet the walker

So, using the formula Speed = Distance/Time

Distance = Speed * Time

The cyclist travels at 14(t + 1/15)

And the walker at 6(t + 1/15)

= 14(t + 1/15) + 6(t + 1/15)

= 20(t + 1/15)

So, when d = 24t and d = 20(t + 1/15)

24t = 20(t + 1/15)

24t = 20t + 20/15

24t - 20t = 4/3

4t = 4/3

12t = 4

t = 4/12

t = 1/3

Since t = 1/3 ,

d = 24t = 24(1/3)

d = 8km

Therefore, Town A is 8km far apart from Town B

Two normal-curves with similar forms but distinct spreads will have the same mean but different standard deviations.

Since the centre of a normal distribution is determined by the mean, the centre of both curves on the horizontal axis will be the same. The spread of a normal distribution is, nevertheless, determined by its standard deviation. A smaller standard deviation indicates that the distribution is more tightly concentrated around the mean, whereas a bigger standard deviation indicates that the distribution is more dispersed.

Since extreme values are more likely to occur, the normal curve with the larger standard deviation will have more area under the curve in the tails. Extreme values are less likely to occur for the normal curve with the smaller standard deviation, which will have less area under the curve in the tails.

When compared to a normal curve with a smaller standard deviation, the larger standard deviation normal curve will visually appear wider and flatter. Both curves will have a bell-shaped curve with the highest point at the mean that is symmetrical around the mean.

Similarities:

The mean of both normal curves, which symbolises the distribution's centre, will be the same.

The mean will be the centre of symmetry for both normal curves.

The area under the curve for both normal curves will be equal to one.

Differences:

Greater standard deviation results in a wider normal curve than smaller standard deviation does.

The data will be more dispersed over the normal curve with a higher standard deviation, whereas the data will be more firmly grouped along the normal curve with a smaller standard deviation.

The peak of the normal curve with a higher standard deviation will be flatter than the peak of the normal curve with a lower standard deviation.

Overall, the two normal curves are comparable in that they both have the same mean, but they differ mostly in terms of their standard deviation, which has an impact on both their spread and the possibility of extreme values.

The interquartile range (IQR) is better than the standard deviation as a measure of dispersion when dealing with skewed data or outliers.

The advantage of using IQR is that it is more resistant to outliers than standard deviation. Standard deviation measures the spread of data around the mean, and if there are outliers in the data, it can be heavily influenced by them.

On the other hand, IQR is calculated using the median and quartiles, which are not affected by outliers. This makes IQR a more robust measure of dispersion in such cases. Additionally, IQR provides information on the range of the middle 50% of the data, which can be more informative than the range of the entire dataset provided by the standard deviation.
