There is two ordered pair greater tan 12 i.e., (2, 8) and (-6,0).

Given,

The equation is :

-5x - 3y = 12

To find the which ordered pair is a solution of above equation.

Now, According to the question:

-5x - 3y = 12

Value is (3, 9) of (x , y)

Substitute in above equation:

-5(3) - 3(9) = 12

-15 - 27 = 12

-42  ≠ 12

Values of (x , y)                                  Equation : -5x -3y = 12

(-5, 5)                                                         = - 10 < 12                                            

(3, -6)                                                         = -33 < 12

(-2, -5)                                                        = -25 < 12

(2, 8)                                                          =  14 > 12

(-6, 0)                                                         = 30 > 12

Question:

Identify which expression is correct.

Solution:

By cross-multiplication notice that:

then, the correct answer is :

To find the minimum score required for an A grade, we need to determine the cutoff point that corresponds to the top 13% of scores.

Given that the scores on the test are normally distributed with a mean of 69.5 and a standard deviation of 9.5, we can use the standard normal distribution to calculate the cutoff point. Using a standard normal distribution table or a statistical calculator, we find that the z-score corresponding to the top 13% is approximately 1.04. To find the corresponding raw score, we can use the formula:

x = μ + (z * σ)

where x is the raw score, μ is the mean, z is the z-score, and σ is the standard deviation. Plugging in the values, we have:

x = 69.5 + (1.04 * 9.5) ≈ 79.58

Rounding this to the nearest whole number, the minimum score required for an A grade would be 80. Therefore, a student would need to score at least 80 on the test to achieve an A grade according to the professor's grading scheme.

Answer:

x=50

Step-by-step explanation:

Answer:

x = 50

Step-by-step explanation:

So the equation is 2x+25=125. you first subtract the 25 from the 125 which you'll get 100 and then divided by 2 which leaves the x alone and so 100/2 = 50 so x= 50

The range of the function g(x) = |x - 12| - 2 is {y | y > -2}, indicating that the function can take any value greater than -2.

To find the range of the function g(x) = |x - 12| - 2, we need to determine the set of all possible values that the function can take.

The absolute value function |x - 12| represents the distance between x and 12 on the number line. Since the absolute value always results in a non-negative value, the expression |x - 12| will always be greater than or equal to 0.

By subtracting 2 from |x - 12|, we shift the entire range downward by 2 units. This means that the minimum value of g(x) will be -2.

Therefore, the range of g(x) can be written as {y | y > -2}, which means that the function can take any value greater than -2. In other words, the range includes all real numbers greater than -2.

Visually, if we were to plot the graph of g(x), it would be a V-shaped graph with the vertex at (12, -2) and the arms extending upward infinitely. The function will never be less than -2 since we are subtracting 2 from the absolute value.

The radian measure 5π/6 is equivalent to 150 degrees. To convert radians to degrees, we can use the formula:

Degrees = Radians × (180/π)

In this case, we have the radian measure 5π/6. Plugging this into the formula, we get:
Degrees = (5π/6) × (180/π)

The π cancels out, leaving us with:
Degrees = (5/6) × 180

Simplifying further:
Degrees = (5/6) ×

180 = 150

Therefore, the radian measure 5π/6 is equivalent to 150 degrees.

To convert radians to degrees, we can use the formula

Degrees = Radians × (180/π). In this case, we have the radian measure 5π/6. Plugging this into the formula, we get Degrees = (5π/6) × (180/π). The π cancels out, leaving us with

The t-value is often used instead of the z-value in statistical tests because the assumptions of the z-value are violated when the sample size is 30 or less.

The t-value is preferred over the z-value in certain scenarios due to the violation of assumptions associated with the z-value when the sample size is small (30 or less). The z-value assumes that the population standard deviation is known, which is often not the case in practice. In situations where the population standard deviation is unknown, the t-value is used because it relies on the sample standard deviation instead. By using the t-value, we account for the uncertainty associated with estimating the population standard deviation from the sample.

Additionally, the t-value is easier to calculate and interpret compared to the z-value. The t-distribution has a wider range of degrees of freedom, allowing for more flexibility in analyzing data. Moreover, the t-value is more widely known among statisticians and is readily available in statistical software packages, making it a convenient choice for conducting hypothesis tests and confidence intervals.

Overall, the t-value is preferred over the z-value when the assumptions of the z-value are violated or when the population standard deviation is unknown.

Answer:its B

Step-by-step explanation:

No, the line passing through  (-4, 26) and (-2, 0) is  not parallel to line passing through (10, 18) and (5, 3) because slopes of both lines are different.

Line is possible in 2-d forms so, it has only x and y-co-ordinates. Z-co-ordinates is not possible.

We know very well that to prove any two lines are parallel to each other we need to prove only whether their slopes are equal or not.

Now, talking about the slopes we know that if any line is passing from point(x₁,y₁) and again passing from other point(x₂,y₂) then slope(m) of that line is given by the formula=(y₂-y₁) / (x₂-x₁)

So, for first line we have (x₁, y₁)=(-4,26)

and (x₂, y₂)=(-2,0)

So, slope(m₁) of first line is =(0-26)/(-2 - (-4))

                  =>m₁ = -26/2

                   =>m₁ = -13     ----(eq1)

Similarly, for second line, we have (x₁, y₁)=(10,18)

and (x₂, y₂)=(5,3)

So, slope(m₂) of second line is =(3-18) / (5-10)

                =>m₂ = -15/-5

                 =>m₂=     3   -------(eq2)

On comparing eq1 and eq2,we get

 =>m₁≠m₂.

A sample of matter experiences a decrease in average kinetic energy as it continues to cool. One would anticipate that the particles will eventually come to a complete stop. The temperature at which particles should theoretically stop moving is absolute zero. Thus, option B is correct.

What theory directly contradicts concept of absolute zero?

All molecules are predicted to have zero kinetic energy and, as a result, no molecular motion at absolute zero (273.15°C). Zero is a hypothetical value (it has never been reached).

Absolute zero signifies that there is no kinetic energy involved in random motion. A substance's atoms don't move relative to one another.

Therefore, Kinetic energy because it can create heat which goes against the absolute zero. A gas molecule's kinetic energy tends to zero when the temperature reaches absolute zero.

The statement is incorrect. Chi-square tests can be conducted for contingency tables of any size, not just limited to 2x2 tables.

Chi-square tests

are statistical tests used to determine the association or independence between two categorical variables. While the

2x2

contingency table is commonly used in chi-square tests, it is not the only size that can be analyzed.

Contingency tables

can have any number of rows and columns, representing different categories or levels of the variables being studied. The chi-square test of independence or goodness-of-fit can be performed on contingency tables of various dimensions, including larger tables.

For example, if we have a contingency table with three rows and four columns, it is still possible to conduct a chi-square test to examine the association between the two categorical variables represented by the table.

The chi-square test calculates the expected frequencies based on the null hypothesis of independence or a specified distribution, compares them with the observed

frequencies

, and determines if there is a significant difference. The test statistic follows a chi-square distribution with degrees of freedom determined by the table's dimensions.

Therefore, it is incorrect to state that chi-square tests can only be conducted for a 2x2 contingency table. These tests are applicable to contingency tables of any size, allowing for the analysis of associations and dependencies between categorical variables with multiple categories.

The percent markup is 25%.

Markup percentage is calculated by dividing the gross profit of a unit (its sales price minus it's cost to make or purchase for resale) by the cost of that unit.

Given that, A department store buys 300 shirts for a total cost of $7,200 and sells them for $30 each.

Cost of one shirt \(= 7200 \div 300 = \$24\)

And they sold at $30 each,

Percent markup \(= 30-24 \div 24 \times 100\)
