Option A is correct i.e., Regression with class performance as the dependent variable would be the most beneficial statistical procedure for identifying key factors in a student's success in statistics class.

Using this strategy, you may pinpoint the crucial independent factors that are most closely linked to academic achievement and gauge the degree and direction of those associations.

Contrarily, using the success in statistics class as an independent variable would prevent you from identifying the additional factors that affect class success, while confidence intervals and hypothesis testing would not reveal information on the particular independent variables that are most crucial.

The following system of two equations: 4.0x + 7.5y = 3 2.5x + 8.0y =9, The value of y in the given system of equations is y = 0.8.

To solve the system of equations, we can use the method of substitution or elimination. Here, we'll use the method of elimination:

Multiply the first equation by 2.0 and the second equation by -4.0 to eliminate the x term:

(8.0x + 15.0y = 6)

- (10.0x + 32.0y = -36)

This simplifies to: -17.0y = -42

Dividing both sides of the equation by -17.0, we get: y = 42/17 ≈ 0.8

Therefore, the value of y in the given system of equations is y = 0.8.

Answer: The mean increases by 1.6°.

Step-by-step explanation:

The mean is the average or the sum of all the data divided by the amount of data.

58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 = 965

There are 12 data points so...

965 / 12 ≈ 80.4

To find the new mean add 101 to 965, then divide by 13.

965 + 101 = 1066

1066 / 13 = 82

The mean increases by 1.6°.

The probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring, this statement is false.

The union of two or more sets refers to the set with all the elements belonging to each set. An element is said to be in the union if it lies to at least one of the sets.

The intersection of two or more sets refers to the set of elements universal to each set. An element is in the intersection if it occurs in all of the sets.

The event that both A and B occur is the intersection of the events A occurs and B occurs. As such, it is a subset of each and cannot, therefore, have a larger probability than either one individually.

All the real values of p such that 2(x - 4)(x - 2p) has a minimum value of -18 over all real values of x is p = 1 and p = -5.

Given that:

2(x + 4)(x - 2p)

It is required to find the values of p such that this expression has a minimum value of -18.

Expand the given expression.

2(x² + 4x - 2px - 8p)

2(x² + (4 - 2p)x - 8p)

2x² + (8 - 4p)x - 16p

The minimum value of the function can be found by first, setting the derivative equal to 0.

Differentiating,

4x + (8 - 4p) = 0

4x = 4p - 8

x = p - 2

Substitute x = p - 2 to the function 2(x + 4)(x - 2p).

When the value of the function is -18,

2(p - 2 + 4)(p - 2 - 2p) = -18

2(p + 2)(-p - 2) = -18

(p + 2)(-p - 2) = -9

(p + 2)² = 9

p + 2 = ±3

When p + 2 = 3, p = 1.

When p + 2 = -3, p = -5.

Hence the p values are 1 and -5.

Answer: y = 5x + 26

Step-by-step explanation:

To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Substituting the values, we get:

y - 1 = 5(x - (-5))

Simplifying further:

y - 1 = 5(x + 5)

Expanding the brackets:

y - 1 = 5x + 25

Rearranging the equation to the slope-intercept form (y = mx + b):

y = 5x + 26

Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

The graph of the sine function f(x) = sin(400πx) is given by the image at the end of the answer.

The sine function in this problem is defined as follows:

f(x) = sin (y × 2πx).

In which the relevant variable for the graph is the variable y, which is the number of cycles in a single second of the wave.

In this problem, it is states that the note has a frequency of 440 Hz, meaning that it has 440 cycles in one second, thus the equation is:

f(x) = sin (440 × 2πx).

f(x) = sin (880πx).

The function is not multiplied by any value, hence the amplitude is of 1, meaning that the function oscillates between 0 and 1, and also there is not any phase shift or vertical shift, meaning that it oscillates between -1 and 1 starting at the origin.

a) The high temperature for today using a 3-day moving average = 92.7 degrees.

b) The high temperature for today using a 2-day moving average = 91.5 degrees.

c) The mean absolute deviation based on a 2-day moving average = 1.5 degrees.

d) The mean squared error for the 2-day moving average = 2.25 degrees².

e) The mean absolute percent error (MAPE) for the 2-day moving average = 2.9%.

To calculate the high temperature for today using a 3-day moving average, we sum the high temperatures of the last three days (90, 93, and 95), and then divide the sum by 3. This gives us an average of 92.7 degrees, rounded to one decimal place.

For a 2-day moving average, we sum the high temperatures of the last two days (90 and 93), and divide the sum by 2. This gives us an average of 91.5 degrees, rounded to one decimal place.

To calculate the mean absolute deviation based on a 2-day moving average, we first find the absolute difference between each high temperature and the 2-day moving average (91.5 degrees). The differences are 1.5, 1.5, 1.5, 2.5, 3.5, and 1.5. Then, we calculate the average of these differences, which is 1.5 degrees, rounded to one decimal place.

The mean squared error for the 2-day moving average is calculated by squaring the differences between each high temperature and the 2-day moving average (91.5 degrees), and then finding the average of these squared differences. In this case, the squared differences are 2.25, 2.25, 2.25, 6.25, 12.25, and 2.25. The average of these squared differences is 4.83 degrees^2, rounded to one decimal place.

The mean absolute percent error (MAPE) for the 2-day moving average is calculated by finding the absolute difference between each high temperature and the 2-day moving average (91.5 degrees), dividing this difference by the high temperature, and then finding the average of these percentages. The percentages are 1.6%, 1.6%, 1.6%, 2.6%, 3.7%, and 1.6%. The average of these percentages is 2.9%, rounded to one decimal place.

Statistics computed for larger random samples tend to be less variable compared to statistics computed for smaller random samples.

This statement is based on the concept of the Central Limit Theorem (CLT) in statistics. According to the CLT, as the sample size increases, the distribution of the sample mean approaches a normal distribution regardless of the shape of the population distribution. This means that the variability of the sample mean decreases as the sample size increases.

The variability of a statistic is commonly measured by its standard deviation or variance. When working with larger random samples, the individual observations have less impact on the overall variability of the statistic. As more data points are included in the sample, the effects of outliers or extreme values tend to diminish, resulting in a more stable and less variable estimate.

In practical terms, this implies that estimates or conclusions based on larger random samples are generally considered more reliable and accurate. Researchers and statisticians often strive to obtain larger sample sizes to reduce the variability of their results and increase the precision of their statistical inferences.

Matsu should use feet as the unit of measurement to eliminate the need to write the values in scientific notation.

Measurement units are standardized quantities used to express the size, amount, or degree of something. They are essential for communicating and comparing measurements consistently across different fields, disciplines, and countries.

Measurement units fall into two categories:

Basic units: These are the fundamental units of measurement that are used as the building blocks to create other units. Examples of basic units include the meter (for length), the kilogram (for mass), the second (for time), the kelvin (for temperature), the mole (for amount of substance), and the candela (for luminous intensity).

Derived units: These are units that are created by combining one or more basic units. Examples of derived units include the Newton (for force, which is a combination of mass and acceleration), the Joule (for energy, which is a combination of force and distance), and the Watt (for power, which is a combination of energy and time).

Matsu should use feet as the unit of measurement to eliminate the need to write the values in scientific notation. Feet are a larger unit of measurement than inches, and they are commonly used for measuring dimensions of larger objects such as gardens. Cups and tons are units of measurement used for measuring volume and weight, respectively, and are not appropriate for measuring the dimensions of a garden.

The probability that all four songs are liked will be 0.03418 and the probability of not liking the next four songs will be 0.99658.

The probability of an event occurring is defined by probability.

Probability is also called chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

As per the given,

Total songs = 53

Like songs = 14

Probability of selecting and liking the first song = 14/53

Now since repetition is not allowed and one like the song has been chosen out of 14 thus, the remaining songs = 13, and total songs = 43 - 1 = 52

Probability of selecting liking the second song = 13/52

Probability of selecting liking the third song = 12/51

Probability of selecting liking the fourth song = 11/50

a)

The probability of liking all songs will be 14/53 x 13/52 x 12/51 x 11/50 = 0.03418.

b)

The probability of not liking the next four songs =1 - The probability of liking all songs

The probability of not liking the next four songs = 1 - 0.03418 = 0.96582.
