No, a sample size of only 5 young students in an elementary school is not likely to be representative of the school as a whole. In order to get a better understanding of the school population and have a more accurate representation, a larger and more diverse sample should be surveyed. The sample size should be large enough to ensure that it accurately reflects the diversity of the school, including different socio-economic backgrounds, ages, and races. Furthermore, it should also include a mix of genders and different academic abilities. If the sample size is too small or does not reflect the school population accurately, the results of the survey may not be reliable. Thus, a larger and more diverse sample should be used in order to get a more representative representation of the school.

The tendency to perceive meaningful patterns in random sequences of outcomes often leads us to underestimate the extent to which outcomes result from CHANCE .

The word "chance" describes unpredictability or the unexpected in relation to things like events that happen without a clear reason why and without human intention.

The conclusion is that chance is the tendency of people to recognize different kinds of significant patterns in a random order or sequence in addition to evaluating any kind of outcome. Because chance can also result in an underestimating of a system's conclusion or result, it is crucial to consider it when conducting an investigation.

Answer:

y = -19.5, x = -14.5

Step-by-step explanation:

We can form equations from this statement:

x + y = -34

x - y = 5

If we rearrange the second equation, we get:

x - y = 5

x = 5 + y

Then, we substitute this value into the other equation to get the answer.

x + y = -34

5 + y + y = -34

Then solve:

2y + 5 = -34

2y = -39

so, y = -19.5

now we can find x with y:

-19.5 + x = -34

-34 + 19.5 = x

x = - 14.5

Step-by-step explanation:

The line y = -x, passing through the origin in the xy-plane, forms a 45-degree angle with the positive x-axis.

The slope-intercept form of a linear equation is y = mx + b, where m represents the slope of the line. In this case, the equation y = -x has a slope of -1. The slope indicates the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

To determine the angle between the line and the positive x-axis, we need to find the angle that the line's slope makes with the x-axis. Since the slope is -1, the line rises 1 unit for every 1 unit it runs. This means the line forms a 45-degree angle with the x-axis.

The angle can also be determined using trigonometry. The slope of the line (-1) is equal to the tangent of the angle formed with the x-axis. Therefore, we can take the inverse tangent (arctan) of -1 to find the angle. The arctan(-1) is -45 degrees or -π/4 radians. However, since the line is in the positive x-axis direction, the angle is conventionally expressed as 45 degrees or π/4 radians.

The expected value is the long-term average outcome of a random variable. It is calculated by multiplying each possible outcome by its probability and summing them up. In simpler terms, it represents the average value we expect to get over many trials.

The expected value is a concept in probability and statistics that represents the long-term average outcome of a random variable. It is also known as the mean or average. To calculate the expected value, we multiply each possible outcome by its probability and sum them up.

For example, let's say we have a fair six-sided die. The possible outcomes are numbers 1 to 6, each with a probability of 1/6. To find the expected value, we multiply each outcome by its probability:

Summing up these values gives us:

1/6 + 2/6 + 3/6 + 4/6 + 5/6 + 6/6 = 21/6 = 3.5

Therefore, the expected value of rolling a fair six-sided die is 3.5. This means that if we roll the die many times, the average outcome will be close to 3.5.

(4k-9)(2k-2)

First you're going to want to multiply the 4k by the 2k & the -2. Then you're going to want to multiply the -9 by the 2k and the -2.

(4k-9)(2k-2)

4k * 2k = 8k^2

4k * -2 = -8k

-9 * 2k = -18k

-9 * -2 = +18

Since we have like terms (-8k and -18k) put those together.

-8k + -18k = -26k.

Now you're going to want to put all of these together in an equation.

You want to order the numbers from the highest number of exponents (8k^2) to the lowest.

8k^2 - 26k + 18

So the correct answer is 8k^2 - 26k + 18.

Step-by-step explanation:

The probability of winning the new boat is unlikely, since there is only one boat behind one of the five doors, while the other four doors have joke prizes. Assuming that each door has an equal chance of being selected by the contestant, the probability of choosing the door with the boat is 1/5 or 20%. However, the probability of not winning the boat is 4/5 or 80%. Therefore, it is unlikely that the contestant will win the boat.

The multifactor productivity measure for each of the weeks shown for the production of chocolate bars assuming a 40-hour week and an hourly wage of $16 and overhead costs 1.5 times labor cost is 0.127.

Multifactor productivity is an economic metric that calculates the ratio of an organization's total outputs to its total inputs used for production over a given period. It determines how efficiently the organization uses its resources in the production process, and it is calculated using the formula :

MFP = Total output / ( Labor cost + Material cost + Overhead cost)Where MFP stands for multifactor productivity. Overhead costs, labor costs, and material costs are the inputs used for production.

The data provided is shown in the table below:| Week | Output | Labor | Materials | Overhead | |------|--------|-------|-----------|----------| | 1 | 3000 | 100 | 6000 | 150 | | 2 | 4500 | 150 | 9000 | 225 | | 3 | 6000 | 200 | 12000 | 300 |For each week, we must first calculate the labor, material, and overhead costs.

Labor cost per week = number of hours worked x hourly wage

Labor cost per week = 40 x $16 = $640

Material cost per week is given.

Overhead cost per week = 1.5 x labor cost

Overhead cost per week = 1.5 x $640 = $960

Now that we have all of the necessary input data, we can use the MFP formula to calculate multifactor productivity for each week.MFP for Week 1 = 3000 / (100 x $16 + $6000 + $150 + $960)MFP for Week 1 = 0.127MFP for Week 2 = 4500 / (150 x $16 + $9000 + $225 + $960)MFP for Week 2 = 0.127MFP for Week 3 = 6000 / (200 x $16 + $12000 + $300 + $960)MFP for Week 3 = 0.127
