The given problem is about the motion of a cyclist on a straight road. The motion is divided into three parts, and different average speeds of the cyclist for each part are given.

The problem asks to calculate the total distance traveled by the cyclist and the average speed of the cyclist for the entire trip. Let's solve the problem:

Given data:

First part: time taken t1 = 25.8 min = 25.8 × 60 s = 1548 s.

Average speed v1 = 6.14 m/s.

Second part: time taken t2 = 37.5 min = 37.5 × 60 s = 2250 s.

Average speed v2 = 5.00 m/s.

Third part: time taken t3 = 5.51 min = 5.51 × 60 s = 331 s

Average speed v3 = 15.7 m/s(a) Total distance traveled by the cyclist:

To find the total distance traveled by the cyclist, we need to add the distance traveled in each part of the motion. We know that distance = speed × time.

First part: Distance1 = v1 × t1 = 6.14 m/s × 1548 s = 9483.12 m

Second part: Distance2 = v2 × t2 = 5.00 m/s × 2250 s = 11250.00 m.

Third part: Distance3 = v3 × t3 = 15.7 m/s × 331 s = 5190.70 m.

Total distance traveled by the cyclist = Distance1 + Distance2 + Distance3= 9483.12 m + 11250.00 m + 5190.70 m = 25923.82 mSo, the total distance traveled by the cyclist is 25923.82 m.

(b) Average speed of the cyclist: To find the average speed of the cyclist for the entire trip, we use the formula for average speed, which is Average speed = Total distance traveled / Total time taken.

Total time taken for the entire trip = t1 + t2 + t3 = 1548 s + 2250 s + 331 s = 3129 sNow, we can find the average speed of the cyclist:

Average speed = Total distance traveled / Total time taken= 25923.82 m / 3129 s = 8.28 m/s.

Therefore, the average speed of the cyclist for the entire trip is 8.28 m/s.

Total distance traveled by the cyclist is 25923.82 m. The average speed of the cyclist for the entire trip is 8.28 m/s.

The ordered triplet (x, y, z) or the following system of equations: x+3y + 2z = 1, 03x+y+5z=10, -2x-3y+z=7 is (-170/127, -89/127, 282/127).

Start with the first equation:

x + 3y + 2z = 1

Isolate x by subtracting 3y and 2z from both sides:

x = 1 - 3y - 2z

Substitute this expression of x into the second equation:

0.3x + y + 5z = 10

Substitute the value of x found in step 2 into this equation:

0.3(1 - 3y - 2z) + y + 5z = 10

0.3 -0.9y -0.6z + y + 5z = 10

0.1y + 4.4z = 9.7

y + 44z = 97

Solve for y by isolating it:

y = 97 - 44z

Substitute this expression of y into the first equation:

x + 3(97 - 44z) + 2z = 1

x + 291 - 132z + 2z = 1

Solve for x:

x = 130z - 290

Substitute this expression of x into the third equation:

-2(130z - 290) - 3(97 - 44z) + z = 7

-260z + 580 - 291 + 132z + z = 7

Solve for z:

127z = 282

z = 282/127

Substitute this value of z into the expression of y:

y = 97 - 44(282/127)

= -89/ 127

Substitute the values of z into the expression of x:

x = 130(282/127) - 290

= - 170/ 127

So the solution of the system of equations is: x = -170/127, y = -89/127, z = 282/127.

If f (x) < g(x) for all real 1; The expression that must be true is I f'(x)sg'(x) for all real x II. f'(x)≤g'(x) for all real x III. f(x)dx ≤ [8(x)dx is option D. I and II only

I. f(x) and g(x) have continuous first and second derivatives everywhere, so by the mean value theorem, there exists a point c in the interval (a, b) such that f'(c) = (f(b) - f(a)) / (b - a) and g'(c) = (g(b) - g(a)) / (b - a). Since f(x) < g(x) for all x, we have f(b) - f(a) < g(b) - g(a), so f'(c) < g'(c), and thus, f'(x) < g'(x) for all x.

II. f(x) and g(x) have continuous first and second derivatives everywhere, so by the mean value theorem, there exists a point c in the interval (a, b) such that f''(c) = (f'(b) - f'(a)) / (b - a) and g''(c) = (g'(b) - g'(a)) / (b - a). Since f'(x) < g'(x) for all x, we have f'(b) - f'(a) < g'(b) - g'(a), so f''(c) < g''(c), and thus, f''(x) < g''(x) for all x.

III. This statement is not necessarily true. The definite integral of f(x)dx is equal to the area between the curve and the x-axis, and the definite integral of g(x)dx is equal to the area between the curve and the x-axis. The definite integral of a function does not depend on the value of the function at each point, but on the overall shape of the curve, so it is not guaranteed that f(x)dx ≤ g(x)dx just because f(x) < g(x) for all x.

There are no remaining rolls, and the average approaching 3.5 is simply the current average of 3.51.

It is the average value of the set given.

It is calculated as:

Mean = Sum of all the values of the set given / Number of values in the set

We have,

To find the average approaching 3.5, we need to use the concept of the mean or expected value.

The expected value of a random variable is the long-run average value that we would expect to get if we repeat an experiment many times.

In this case, we can consider each roll of a die as an experiment, and the value of the die as the random variable.

Assuming that the die is fair and has six equally likely outcomes, each with a value between 1 and 6, the expected value of the die is:

E(X) = (1 + 2 + 3 + 4 + 5 + 6)/6 = 3.5

Therefore, if we roll the die many times, we would expect the long-run average value to be 3.5.

Now, if we have rolled the die 3200 times and the average so far is 3.51, we can calculate the sum of all the values rolled so far as:

Sum = (Average so far) x (Number of rolls) = 3.51 x 3200 = 11232

To find the average approaching 3.5, we need to calculate the average of the remaining rolls. Let's call the number of remaining rolls "n". Then we have:

Average approaching 3.5 = (Sum of remaining rolls) / n

We know that the total number of rolls is 3200, so the number of remaining rolls is:

n = 3200 - (number of rolls already rolled)

n = 3200 - 3200 = 0

Therefore,

There are no remaining rolls, and the average approaching 3.5 is simply the current average of 3.51.

Answer:

(x + 1)(3x - 10)

Step-by-step explanation:

Given

3x² - 7x - 10

Consider the factors of the product of the x² term and the constant which sum to give the coefficient of the x- term.

product = 3 × - 10 = - 30 and sum = - 7

The factors are + 3 and - 10

Use these factors to split the x- term

3x² + 3x - 10x - 10 ( factor the first/second and third/fourth terms )

3x(x + 1) - 10(x + 1) ← factor out (x + 1) from each term

(x + 1)(3x - 10), thus

y = (x + 1)(3x - 10) ← in factored form

Therefore, when y = 10 and z = 5, the value of the expression 0.3y + y/z is 5.

In mathematics, an expression is a combination of numbers, variables, and operators that are grouped together to represent a mathematical quantity or relationship. Expressions can be simple, such as a single number or variable, or they can be more complex, involving multiple operations and variables. Expressions are often used in mathematics to represent relationships between variables, to evaluate quantities, and to solve equations.

Here,

Substituting y = 10 and z = 5 in the given expression, we get:

0.3y + y/z = 0.3(10) + 10/5

we have given that the A population of N = 10 scores has μ = 50 and σ = 5. And we have to find the population variance.

So, For this purpose,

we know that the population variance can be defined as the average of the distances from each data point in a particular population to the mean squared, and it indicates how data points are spread out in the population.

Population variance = mean /(standard deviation/number of samples)

Population variance = μ / (σ /N )

The commonly used technique in problem solving is means-end analysis

One typical heuristic is to define subproblems or subgoals. Means-ends analysis, which entails determining how to close the gap between a goal and the actual situation, is another frequently employed heuristic. You can divide a problem into smaller problems and deal with each one separately by using means-ends analysis.

Heuristic problem-solving entails what?

A problem-solving heuristic is a non-formal, speculative process that, in certain circumstances, produces a solution but not in others. The strategy can be either more or less successful than employing an algorithm because the results of applying a heuristic are unpredictable.

A important goal of inferential statistical analysis is to generalize results from the study to the target population (option c).

An important goal of inferential statistical analysis is to generalize the findings and results obtained from a study or sample to the larger target population. Inferential statistics involves making inferences, drawing conclusions, and making predictions about a population based on the analysis of a sample.

When conducting a study, it is often impractical or impossible to collect data from the entire population of interest. Instead, a sample is typically selected and studied. Inferential statistics helps researchers make inferences about the population based on the sample data.

By analyzing the sample data using inferential statistical techniques, researchers can estimate population parameters, test hypotheses, determine the significance of findings, and make predictions about the larger population. This allows for generalization of the findings and helps in making informed decisions and drawing conclusions that extend beyond the specific sample studied.

Options A, B, and D are also important goals in statistical analysis, but they are not specific to inferential statistics. Analyzing and describing data (option A) is a goal of descriptive statistics. Determining the validity of theoretical constructs (option B) and measuring the reliability and validity of measurement tools (option D) are goals related to assessing the quality and soundness of research instruments and constructs, but they do not specifically address the goal of generalizing results to a larger population. The correct option is c.
