It’s the average distance to the Mean also measures how far is the data spread apart in the population.

What is Population?

In statistics, a population refers to the entire group or set of individuals, objects, or events that share a common characteristic or feature. The population can be any size, from a small group of people to an entire country or even the whole world.

In order to make statistical inferences about a population, it is often not practical or feasible to study the entire population. Instead, researchers typically take a sample from the population, which is a smaller subset of the population, and use the sample data to make predictions or draw conclusions about the population as a whole.

The average distance to the mean (or average) also measures how far the data is spread apart in the population.

This is commonly known as the standard deviation, which is a measure of the amount of variation or dispersion in a set of data values. A larger standard deviation indicates a greater amount of variability or spread in the data, while a smaller standard deviation indicates that the data points are closer to the mean.

Answer:2/9

Step-by-step explanation:

Answer:

12 units

Step-by-step explanation:

The probability that the result is a multiple of five and a multiple of two is 1/3, since there are only three multiples of five and two that can be produced on the spinner: 10, 6, and 2.

The spinner has 12 equal areas, numbered one through 12. The probability of getting a multiple of five and a multiple of two on one spin is 1/3, since there are only three multiples of five and two that can be produced: 10, 6, and 2. To calculate this probability, we need to look at the total number of possible outcomes and divide it by the number of outcomes that are multiples of five and a multiple of two. In this case, the total number of outcomes would be 12, and the number of outcomes that are multiples of five and a multiple of two is three (10, 6, and 2). Dividing 12 by 3 gives us the probability of 1/3.

Total number of outcomes = 12

Number of outcomes that are multiples of five and two = 3 (10, 6, and 2)

Probability = 3/12 = 1/3

Answer:

[tex]x \leq \frac{1}{3}[/tex] or [tex]x \geq \frac{1}{2}[/tex]

Answer:

Below

Step-by-step explanation:

From the graph below you can see that

x < = .33 3   and   x >= .5

combined

  .333  ≥  x  ≥  .5

The slope of the line that contains the points (10, 0) and (-20, -18) is: slope = (change in y)/(change in x) = 3/5.

The slope of a line is the measure of its steepness, and it's found by dividing the change in the y-coordinates by the change in the x-coordinates between two points on the line. In this case, the slope of the line that passes through the points (10, 0) and (-20, -18) can be calculated as follows:

slope = (change in y-coordinates) / (change in x-coordinates)

slope = (-18 - 0) / (-20 - 10)

slope = -18 / -30

slope = 3/5

Therefore, the slope of the line is 3/5.

Answer:

A)  Missing Table Values.  See the attached worksheet

B)  The car will be worth less than $8,000 in 9.8 years

Step-by-step explanation:

Part B:  Years until car is less than $8,000

 The new $25,000 car depreciates by 11% each year.  Expressed another way, it retains 89% of its value each year.  The value, y, after x years can be calculated from:

                                 y = ($25,000)*(0.89)^x

This function is graphed on the attached worksheet.  The line intersets the $800 on the y axis at 9.8 years.  The car will be worth less than $8,000 after 9.8 years.

One can also calculate the value of x:

                            $,8000 = ($25,000)*(0.89)^x

        x = 9.77, mathematically

Part A:  Table of values

See the attached worksheet.  The values are not exactly a straight line, but come close to f(x) = 8x+50, from which the missing values may be calculated.  Legally, however, this is a slightly more complex line, for which I'm unclear about the best approach for its derivation.

Answer:

B. inductive

Step-by-step explanation:

An inductive reasoning process involves making a generalization based on specific observations. In the case of the given question, the statement is: "A _______ is an educated guess based on patterns in data figures."

To use inductive reasoning to find the answer, we can follow these steps:

Look for patterns in the data figures. Identify the commonalities between different examples of educated guesses.

Based on these patterns, make an initial generalization about what the blank might be. For example, if we notice that all educated guesses involve making a prediction based on previous observations, we might guess that the missing word is "conjecture."

Test the generalization by looking at additional examples. Do these examples fit the pattern we identified earlier? If so, our initial guess might be correct. If not, we might need to revise our generalization or consider other options.

Continue testing and refining the generalization until we feel confident that it accurately describes the relationship between the given words.

In this case, using inductive reasoning, we can make an educated guess that the missing word is "conjecture," as it fits the pattern of being an educated guess based on patterns in data figures.

The domain and range for the function f(x) = 2x include the following:

Range = (-∞, ∞).

In Mathematics, a domain is the set of all real numbers for which a particular function is defined.

Additionally, the vertical extent of any graph of a function represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.

By critically observing the graph shown in the image attached above, we can reasonably and logically deduce the following domain and range:

The line that goes through the points (0, -2) and (4, -2) can be represented by the equation y = (-1/2)x - 2.

Since both points have the same y-coordinate of 5, the line must be a horizontal line passing through y = 5. Therefore, the equation of the line is y = 5.

Since both points have the same y-coordinate of 0, the line must also be a horizontal line passing through y = 0. Therefore, the equation of the line is y = 0.

The slope of the line passing through the two points can be found using the formula:

m = (y₂ - y₁) / (x₂ - x₁)

Substituting the given values, we get:

m = (-2 - 0) / (4 - 0) = -1/2

Using the point-slope form of the equation of a line, we can write the equation of the line as:

y - y₁ = m(x - x₁)

Substituting one of the given points, such as (0, -2), we get:

y - (-2) = (-1/2)(x - 0)

Simplifying, we get:

y + 2 = (-1/2)x

Therefore, the equation of the line passing through the points (0, -2) and (4, -2) is y = (-1/2)x - 2.

For the given equations, using slope formula option B: Lines 3 and 4 are parallel, is the correct option.

What is slope?

A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.

The four different equations are given.

To identify parallel lines, we need to compare their slopes.

If two lines have the same slope, they are parallel.

Line 1 is in slope-intercept form (y = mx + b) where the slope is m = 8.

Line 2 is in point-slope form (y - y1 = m(x - x1)) where the slope is m = 1/8.

Line 3 is in slope-intercept form where the slope is m = 3.

Line 4 is in slope-intercept form where the slope is m = 1/3.

Comparing the slopes, we see that -

Lines 1 and 2 have different slopes, so they are not parallel.

Lines 1 and 3 have different slopes, so they are not parallel.

Lines 1 and 4 have different slopes, so they are not parallel.

Lines 2 and 3 have different slopes, so they are not parallel.

Lines 2 and 4 have different slopes, so they are not parallel.

Lines 3 and 4 have the same slope (m = 3), so they are parallel.

Therefore, lines 3 and 4 are parallel.

Complex algorithms frequently employ a variable term to guarantee congruence with the two opposing assertions. Equations, which are academic expressions, are used to demonstrate the equality of different academic figures. In this instance, the normalise method provides b + 6 rather than merely expression separating 12 into two pieces for using the data from y + 6.

Here,

To begin, we can construct an expression to symbolise the circumstance:

=> y = 2x + 4

where x represents the number of hours that Quentin rents the shoes for and y represents the overall cost of the rental.

We can put y equal to 11 because we know that Quentin only has $11 to spend:

=> 11 = 2x + 4

We can now determine x:

=> 2x = 11 - 4

=> 2x = 7

=> x = 7/2

Quentin can therefore spend $11 to hire the shoes for 3.5 hours (7/2 hours).

He would have to pay either $10 or $12 to hire the shoes for either three or four hours. He can hire the shoes for three hours with his meagre $11 budget.

The population will take around 6.9 years to triple and 9.2 years to quadruple.

Let P(t) be the population at time t. According to the problem, the rate of increase of the population is proportional to the population itself, which means: dP/dt = kP

where k is the proportionality constant. This is a separable differential equation that can be solved by separating the variables and integrating both sides:

∫ dP/P = ∫ k dt

ln|P| = kt + C

where C is the constant of integration. Applying the initial condition that the population doubles in 4 years, we get:

ln|2p0| = k(4) + C

ln|p0| + ln|2| = 4k + C

ln|p0| + ln|2| - 4k = C

Substituting C into the previous equation and using it for the new population level, we get:

ln|3p0| = kt + ln|p0| + ln|2| - 4k

ln|3p0|/|p0| = kt - 4k + ln|2|

ln|3/2| = (k/ln2)t - 4k/ln2

ln|3/2|/(k/ln2) = t - 4/ln2

t = ln|3/2|/(k/ln2) + 4/ln2
