The numerator of the fraction is 2.

The fraction can be written as 2/7, and since the numerator is nine less than the denominator, when the fraction reduces to (1/7) it means that the numerator must be 2.

To solve this problem, first determine what is given in the question: a fraction with a numerator that is nine less than the denominator, and that reduces to (1/7).

Using this information, the goal is to determine the numerator of the fraction.

To do this, simply subtract nine from the denominator and the result will be the numerator. In this case, the denominator is 7, so subtracting 9 from 7 gives us 2, which is the numerator of the fraction.

Therefore, the numerator of the fraction is 2.

Step-by-step explanation:

it takes approximately 13.61 minutes for NASA's radio signals to reach the Curiosity rover on Mars.

To calculate the time it takes for NASA's radio signals to reach the Curiosity rover on Mars, we need to consider the speed of light.

The speed of light in a vacuum is approximately 299,792 kilometers per second or about 186,282 miles per second.

Given that the Curiosity rover is 152 million miles away from Earth, we can calculate the time it takes for the radio signals to travel this distance.

Time = Distance / Speed

Time = 152,000,000 miles / 186,282 miles per second

Converting miles to seconds:

Time = 152,000,000 miles / (186,282 miles/second) * (1 second/1 mile)

Time ≈ 816.62 seconds

To convert this to minutes, we divide by 60:

Time ≈ 816.62 seconds / 60 ≈ 13.61 minutes

the measurement of QP=8 CM

The circumference of the circle is approximately 31.4 meters.

The measurement of the circle's perimeter, also known as its circumference, is called the circle's boundary. The region a circle occupies is determined by its area.

To compute the circumference of a circle with radius 5 meters, using the value 3.14 for π, we can use the formula:

C = 2πr

where C is the circumference, π is the mathematical constant pi (approximately equal to 3.14), and r is the radius of the circle.

Substituting the given values, we get:

C = 2 × 3.14 × 5

C = 31.4 meters

Therefore, the circumference of the circle is approximately 31.4 meters.

The quadratic formula mentioned below is used to get the following solutions for x:

\(x = \frac{15y \pm \sqrt{225y^2 - 60y^3}}{15}\)

we can use these solutions of x to find the corresponding values of y:

\(y = \frac{6x \pm \sqrt{36x^2 - 60xy}}{6}\)

Partial derivative is a type of derivative that is taken with respect to one variable, with all other variables held constant.

The local extrema of the function f (x, y) = 3x2y y³−3x²−3y² 2  can be found by taking the partial derivative of the function with respect to x and y and then setting them equal to zero.

This gives us the following equations:

\(\frac{\partial f}{\partial x} = 6xy^3 - 6x = 0\)

\(\frac{\partial f}{\partial y} = 3x^2y^2 - 6y = 0\)

To solve these equations, we can set the partial derivatives equal to each other and solve for y:

\(6xy^3 - 6x = 3x^2y^2 - 6y\)

\(3x^2y^2 - 6y = 6xy^3 - 6x\)

\(3x^2y^2 - 6xy^3 = 6x - 6y\)

\(y(3x^2 - 6xy^2) = 6x - 6y\)

\(y = \frac{6x - 6y}{3x^2 - 6xy^2}\)

Next, we can substitute this expression for y into the equation for the partial derivative with respect to x to get a quadratic equation in x:

\(6xy^3 - 6x = 6x\left(\frac{6x - 6y}{3x^2 - 6xy^2}\right)^3 - 6x\)

\(6xy^3 - 6x = 6x\left(\frac{6x^2 - 36xy + 36y^2}{(3x^2 - 6xy^2)^2}\right) - 6x\)

\(6xy^3 - 6x = 6x\left(\frac{6x^2 - 36xy + 36y^2 - 3x^2 + 6xy^2}{(3x^2 - 6xy^2)^2}\right)\)

\(6xy^3 - 6x = 6x\left(\frac{3x^2 - 30xy + 30y^2}{(3x^2 - 6xy^2)^2}\right)\)

\(0 = 3x^2 - 30xy + 30y^2\)

This equation can be solved using the quadratic formula to get the following solutions for x:

\(x = \frac{15y \pm \sqrt{225y^2 - 60y^3}}{15}\)

Finally, we can use these solutions to find the corresponding values of y:

\(y = \frac{6x \pm \sqrt{36x^2 - 60xy}}{6}\)

Therefore, the local extrema of the function f (x, y) =3x2y y³−3x²−3y² 2  can be found by substituting the solutions for x and y into the original function and classifying them as either maximums or minimums depending on the sign of the function.

The two numbers are 4 and 8 and their product is 32, using algebra to solve for the unknown x and y to represent the numbers.

Let the two numbers be x and y such that we have the ratios;

x - y : x + y : x × y = 1: 3 : 8

(x + y)/xy = 3/8

3xy = 8(x +y) {by cross multiplication}

3xy = 8x + 8y ...(i)

also

(x - y)/xy = 1/8

xy = 8x - 8y {by cross multiplication}

xy = 8x - 8y ...(ii)

add equations (i) and (ii)

4xy = 16x {divide through by 4x}

y = 4

substitute the value of y = 4 in equation (ii)

4x = 8x - 8(4)

4x = 8x - 32

4x = 32 {collect like terms}

x = 32/4 {divide through by 4}

x = 8

Therefore, the unknown numbers are 4 and 8 and their product is 32.

A sampling technique used when groups are defined by their geographical location is cluster sampling. Hence, option A is correct.

Sampling technique refers to the method of selecting or choosing members from the given set of population.

Under cluster sampling method, population is divided or splitted into groups. The key objective is to minimize the cost and time taken.

For example: If a NGO wants to study the rural communities, the state is divided into small groups also known as clusters. Instead of visiting and studying all the locations a random cluster will be choosen and studied. Minimizing time and cost involved. However, it contains more sampling error as it might not represent the entire population accurately.

Close ties between the members of the group typically are formed during the norming stage of group development.

The norming stage of group development is the third stage, where the group begins to establish a sense of cohesion and unity. During this stage, members start to accept each other's ideas and opinions, develop relationships with one another, and establish patterns of communication and interaction. As a result of these positive developments, close ties between the members of the group often begin to form.

In the norming stage, group members also start to identify common goals and work together to achieve them. This shared sense of purpose can further strengthen the bonds between group members and contribute to the formation of close ties.

Overall, the norming stage is an important period of transition for groups as they move from the early stages of forming and storming to a more cohesive and productive group dynamic. The close ties formed during this stage can help to foster a supportive and collaborative environment that benefits the group as a whole.

The minimum wage set by the government at $7.50 per hour does not result in a pay cut for unskilled workers, as it is below the equilibrium wage of $8.00 per hour.

The wage rate remains unchanged, and the labor market remains in balance.

The statement is false.

False.

The equilibrium wage in the market for unskilled labor is $8.00 per hour, which means that the market naturally sets the wage rate at this level, based on the forces of supply and demand.

The government then sets a minimum wage at $7.50 per hour.

Since the minimum wage is below the equilibrium wage, it does not directly impact the wage rate for unskilled workers.
The equilibrium wage represents the point at which the supply of labor (the number of workers willing to work at a given wage) equals the demand for labor (the number of workers that employers are willing to hire at a given wage).

In this case, both workers and employers are satisfied with the $8.00 per hour wage, and the labor market is balanced.
The government sets a minimum wage below the equilibrium wage, it essentially sets a wage floor that is not binding. Employers are still willing to pay the equilibrium wage of $8.00 per hour, and workers are still willing to accept this wage.

The wage for unskilled workers remains at $8.00 per hour, and there is no pay cut of 50 cents per hour.
