Let'S keep track of how many people have good, just only good g p, only a good g mat and not a good g p, both good, so i'm just going to put a check for a good bath good or both bad. Those are our categories, so i'm going to put an x both bad, so we're just going to count up these people. We know a total there's going to be 10 in the sample, so a good g p. A! U was just refreshed. I think a good g p, a was 9.0 and a good g mat was 600 point, so first person, 599 and 9.6, not a good g mat, even though its really close had to be above 600 but g p, a 9.6. That'S a good g p. So we have 1 person in this category of good g p, but not a good g mat then 689 and 8.8. That is a good g mat, but not a good g p. So then, 58410 good g p now to go at 6317.4.

The complete question is:

Graduate Management Admission Test is required of students applying to MBA schools (GMAT). One of the most important indicators of how well a student would likely perform in the MBA program is the GMAT score, which is used by university admissions committees. A sample of 10 graduates was chosen to assess how well the GMAT score predicts MBA achievement. Below are their GMAT scores (which range from 200 to 800) and grade point averages (ranging from 0 to 12) for the MBA program (See Picture).

Suppose that university admissions committees consider a GMAT score higher than 600 as an indicator of a good candidate, and a GPA higher than 9.0 as a good performance. find the probability distribution table that correctly summarizes the data.

The variance is 13.84. Variance is a measure of dispersion that considers the spread of all data points in a data collection, in contrast to range and interquartile range.

The following data set's variance should be calculated: 2, 7, 3, 12, and 9.

The mean must be calculated first. There are 5 data points and the total is 33. The mean is therefore 33 x 5 = 6.6. The next step is to take each data point in the set, subtract the mean, and square the result. For the first value, as an illustration:

(2 - 6.6)2 = 21.16

All values' squared differences are added.

21.16 + 0.16 + 12.96 + 29.16 + 5.76 = 69.20

Next, divide the total by the number of data points:

69.20 ÷5 = 13.84

It varies by 13.84. You must calculate the square root of the variance, which is 3.72, to obtain the standard deviation.

The surface area of pyramid is 229.6 [tex]m^2[/tex] and volume is  164.26 [tex]m^3[/tex].

What is surface area and volume?

The total of a regular pyramid's lateral face areas makes up the lateral surface area. A regular pyramid's total surface area is the sum of the surfaces of its lateral sides and base. The area of a pyramid's base is multiplied by the pyramid's height to determine its volume, which is then divided by 3.

Here Length a = 8 m , Height b = 11.2 m and slant height s= 11m.

Now using surface area of the Pyramid = [tex]\frac{1}{2} (ab)+\frac{3}{2} (bs)[/tex] square unit

=> Surface area = [tex]\frac{1}{2}(8\times 11.2)+\frac{3}{2}(11.2\times 11)[/tex]

=> Surface area = (4×11.2)+(3×5.6×11)

=> surface area = 44.8+184.8 = 229.6 [tex]m^2[/tex]

Now volume of the pyramid =[tex]\frac{1}{3}[/tex] base area ×Height cubic unit

=> volume = [tex]\frac{1}{3}[/tex] × [tex]\frac{1}{2}[/tex]×8×11×11.2 = 164.26 [tex]m^3[/tex]

Answer: 180

Step-by-step explanation:

Answer:

Tangent B = AB/BC = (67^(1/2))/(78^(1/2))

To simplify this fraction, we can multiply both the numerator and denominator by the square root of the denominator's denominator (in this case, 78^(1/2)), which will cancel out the square root in the denominator:

Tangent B = (67^(1/2))/(78^(1/2)) * (78^(1/2))/(78^(1/2)) = (67)/78

Therefore, the tangent of angle B is 67/78 in simplified, rationalized form.

The perimeter of its varignon parallelogram is 30 units.

Diagonal of varignon parallelogram cross at right angle i.e., 90°.

This makes the parallelogram a rhombus.

now, all sides of the rhombus are equal.

When you cut a trapezium into three pieces it is made up of a central rectangle of height 4 units and 2 congruent right-angled triangles whose hypotenuse is 13 units and side is 5 units.

Using Pythagoras theorem,

Another side = √13∧2-5∧2

=√144

=12

Hence the height of the triangle= 12 units.

Now, consider one of the congruent triangles

Half part of the base is included in the other diagonal but the other half is not.

Since the base is 5 so other diagonal is 2.5.

But there are two right triangles so 2.5*2=5 units from the base are not in the other diagonal.

So the diagonal is 14-5=9 units

Hence the diagonal of the rhombus is 12,9 units

and half of the diagonal is 6 and 4.4 respectively

Again, using Pythagoras theorem,

side of the rhombus is equal to 7.5

Hence perimeter = 4x7.5

perimeter = 30

Therefore, The perimeter of its varignon parallelogram is 30 units.

|x| = -x, x < 0.

It measures the distance of a point x to the origin, that is, |2| = |-2| = 2.

For this problem, the number is of $3.96, that is:

|x| = 3.96.

Hence:

Short of $3.96 means that x = -3.96.

The opposite is the other solution, of x = 3.96.

Answer: To find the value of c in the expression n² + 38n + c, we need additional information. Without any additional information, it is not possible to determine the value of c.

In general, c is the constant term in a polynomial equation, it is the coefficient of the term x^0. In this case, c is the coefficient of the term n^0.

However, when c is not given a specific value, it can be any real number, and therefore it cannot be determined without more information.

Step-by-step explanation:

The total number of solutions to a polynomial equation can be determined by analyzing its degree and the number of times that the variable equals to zero. A polynomial equation of degree n will have at most n solutions.

Here is the general rules for finding the number of solutions to a polynomial equation:

If the polynomial is a degree-n equation and has n distinct roots, then it will have n solutions.

For example, the polynomial 5x^3 - x +2 has 3 solutions as it is third-degree polynomial.

It's worth noting that these rules are based on the assumptions that the polynomial is defined over the field of complex numbers, which means that the solutions can be complex numbers, and not just real numbers.

There are several methods to find the solution of a system of two equations with two variables. Some of the most common methods include:

1. Substitution method: In this method, you solve one equation for one variable, and then substitute that value into the other equation. You then solve for the remaining variable, and check your answer by substituting it back into the original equations.

2. Elimination method: In this method, you add or subtract the equations so that one variable is eliminated and you are left with an equation in one variable. You then solve for that variable, and check your answer by substituting it back into the original equations.

3. Graphing method: In this method, you graph both equations on the same coordinate plane, and find the point of intersection, which is the solution of the system.

4. Matrix method: It consists on writing the system in the form of matrix and using specific mathematical operations like Gaussian elimination or Cramer's rule to find the solution.

It's worth to mention that not always systems of two equations have unique solutions, they can have no solutions or infinite solutions, depending on the relative position of the lines that represent the equations.
