4 1/7 divided by 2/3

Answer:

x2−x−6

Step-by-step explanation:

Answer:

(x-3)(x+2)

Step-by-step explanation:

The value of x from given linear equation is -4.

The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

For example, 2x+3=8 is a linear equation having a single variable in it.

Given that x + 16 + x = – 3 x – 4

To find the value of x solving the given linear equation

x + 16 + x = – 3 x – 4

⇒ 2x + 16 = -3x - 4

⇒ 2x + 3x = -4 -16

⇒ 5x = -20

⇒ x = -20/5

⇒ x = -4

Answer: The median of the players' heights is not affected.

Step-by-step explanation: B

The median of the players' heights is increased.

we need to consider the current arrangement of heights and the positions

of the new players in relation to the existing players' heights.

If we assume that the heights of the players are sorted in ascending order,

adding two additional players can affect the median in the following ways:

If both new players have heights lower than the current median:

In this case, adding the new players would not change the median.

The median would remain the same because the new players would be

added below the existing median, and the position of the median would

not shift.

If one new player has a height lower than the current median and the other

has a height higher than the current median:

In this case, the median would be increased.

Adding a taller player would shift the median towards the higher end of the data set.

If both new players have heights higher than the current median:

In this case, the  would be increased.

Both new players would be taller than the current median, causing the

median to shift towards the higher end of the data set.

The probability of rolling an odd number or rolling a 2 on a fair six-sided die is the fraction 2/3

The probability of an event occurring is the fraction of the number of required outcome divided by the total number of possible outcomes

A fair six-sided die has faces numbered 1 to 6, and there are only three numbers that are odd numbers, which are 1, 2, and 3.

so;

probability of rolling an odd number = 3/6

probability of rolling a 2 = 1/6

probability of rolling an odd number or a 2 = 3/6 + 1/6

probability of rolling an odd number or a 2 =4/6

probability of rolling an odd number or a 2 = 2/3

The volume of the parallelepiped with sides given by vectors A, B and C is 13 cubic cm, which is the final answer.

The given vectors are:

A = [-4, 3, 2] cm, B = [2,1,3] cm and C= [1, 1, 4] cm

In order to calculate the volume of parallelepiped, we will use vector triple product equation:

Volume = A . (BXC)|, where BXC represents the cross product of vectors B and C.

Step-by-step solution:

We have, A = [-4, 3, 2] cm

B = [2,1,3] cm

C = [1, 1, 4] cm

Now, let's find BXC, using the cross product of vectors B and C.

BXC = | i    j     k|                    2      1     3                            1      1     4        | i    j     k |  = -i + 5j - 3k

Where, i, j, and k are the unit vectors along the x, y, and z-axes, respectively.

The volume of the parallelepiped is given by:

Volume = A . (BXC)|

Therefore, we have: Volume = A . (BXC)

\(Volume = [-4, 3, 2] . (-1, 5, -3)\\Volume = (-4 \times -1) + (3 \times 5) + (2 \times -3)\\Volume = 4 + 15 - 6\\Volume = 13\)

Answer:

He raised $25.50 over his fund raising goal

Step-by-step explanation:

Here, we want to calculate his fund raising goal.

Let his fund raising goal be $x

We are told that he raised 151% of his fundraising goal;

Thus,

mathematically;

151% of x = 75.5

151/100 * x = 75.5

151x = 100 * 75.5

Step-by-step explanation:

Groups A, B, and C have means of 4, 6, and 8, respectively. There are 15 cases in total, with equal sample sizes in each group. Within is 120. 16-7. 16-4a, the value of omega-squared is 0.25.

What is omega-squared?

       In statistics, omega-squared is a measure of effect size that can be used for one-way ANOVA to determine how much variance is due to the treatment or independent variable. It is calculated by dividing the between-group variance by the total variance, which includes both the within-group and between-group variance.

       Omega-squared is used to determine the percentage of variance accounted for by a particular factor or treatment. It is represented as ω2 and ranges from 0 to 1, with higher values indicating a stronger relationship between the independent variable and the dependent variable.

       The formula for omega-squared is as follows:

                         ω2=SSBetween / SSTotalSSWithin

                              = SSTotal - SS Between

         Where SSTotal is the sum of squares for the total variance.SSBetween is the sum of squares between the groups, and within is the sum of squares within the groups.

     The given information is:

                       Mean of group A = 4Mean of group

                                                 B = 6Mean of group

                                                 C = 8Total cases

                                                    = 15SSWithin

                                                    = 120

             We can calculate the sum of squares between the groups as follows:

                        SSTotal = SSBetween + SSWithinSSTotal

                                      = (nA + nB + nC - 1) × (σA² + σB² + σC²)SSBetween

                                      = SSTotal - SS Within SS Between

                                      = (3 - 1) × (42 + 62 + 82) - 120SSBetween

                                      = 80 Next,

           we can calculate the total variance as:

                      SSTotal = SSWithin + SSBetweenSSTotal

                                    = 120 + 80SSTotal

                                     = 200

            Now, we can calculate omega-squared as follows:

                     ω2 = SSBetween / SSTotalω2

                           = 80/200ω2

                           =0.4

       Hence, the value of omega-squared is 0.25.

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.

The machine lifts the block 2 m high if 15 N of force was applied.

When an object is moved over a distance by an external force, at least a portion of that force must be applied in the direction of the displacement. The SI unit of work is the joule. A joule is the amount of effort that a force of one newton does to move an object one meter. Sometimes, newton meters are used to measure work (N-m). Work is not a vector quantity but a scalar one.

Given:

The0 by the block and the tackle machine = 30 Joules

The force applied by the block and tackle machine = 15 N

We know that W=FD

Here W=30 J

F= 15 N

True. Parametric tests are a category of statistical tests that can only be applied to data that meets certain criteria.

They make use of normal distribution assumptions when analyzing data, which means that a significant proportion of the data must follow a normal distribution for the test to produce valid outcomes

.A sample is a subset of the population that is being examined. The size of the sample has an impact on the accuracy of the study. If the sample size is insufficient, it may not be representative of the entire population. In small sample sizes, the main assumptions of parametric tests may be violated, and the results of the test may be skewed.

A sample is a group of individuals or objects from a population that are chosen for a study. The size of the sample is critical since it has a direct impact on the statistical accuracy of the data. A small sample size can cause the primary assumptions of parametric tests to be broken.

Parametric tests are a type of statistical test that can only be used with specific kinds of data. When parametric tests are used to evaluate data, it is assumed that the data follows a normal distribution. In general, this means that the data should be symmetric around the mean, with the majority of the data values being near the mean and fewer outliers. However, when the sample size is small, the accuracy of these assumptions may be in doubt.

As a result, it's crucial to ensure that you choose the proper statistical test based on the size of your sample and the distribution of your data.

If (2, 0) is a solution of the linear equation \(\displaystyle\sf 2x - 5y = k\), we can substitute the values of \(\displaystyle\sf x = 2\) and \(\displaystyle\sf y = 0\) into the equation to find the value of \(\displaystyle\sf k\).

Substituting \(\displaystyle\sf x = 2\) and \(\displaystyle\sf y = 0\) into the equation, we get:

\(\displaystyle\sf 2(2) - 5(0) = k\)

Simplifying:

\(\displaystyle\sf 4 - 0 = k\)

\(\displaystyle\sf 4 = k\)

Therefore, the value of \(\displaystyle\sf k\) is 4 when (2, 0) is a solution of the linear equation \(\displaystyle\sf 2x - 5y = k\).

The answer is:

4 = k

Work/explanation:

Since we know the values of both x and y, we can plug them into the equation and solve for k:
