As per the given parentage, the highest percentage saying the greens are too fast is females.

In math the term percentage is defined as the number or ratio that can be expressed as a fraction of 100.

Here we have know that the number male players are

Male Golfers                                    Greens Condition              

Handicap                               Too fast                        Fine

Under 15                                       10                             40

15 or more                                     25                           25

And the female players are,

Male Golfers                                     Greens Condition            

Handicap                               Too fast                         Fine

Under 15                                       1                                9

15 or more                                   39                              51

Then the total value of them is calculated as,

                      Too fast                   Fine             Total

Male                   35                          65               100

Female              40                           60               100

All of the angles in an acute triangle are less than 90 degrees. Triangles are referred to as right triangles when one of their angles is 90 degrees.

The three vertices of a triangle make it a three-sided polygon. The angles of the triangle are formed by the three sides' end-to-end connections at a point. 180 degrees is the sum of the triangle's three angles. With three sides and three vertices, triangles are a particular kind of polygon in geometry.

It has three straight sides and is a two-dimensional figure. As a 3-sided polygon, a triangle is included. Three triangle angles added together equal 180 degrees. In one plane, the triangle is contained. When three straight lines cross, a triangle is the result. There are always three sides and three corners to a triangle (angles). A triangle's vertex is the location at which two of its sides meet.

The person will have to place the compasses 6 feet away from the point they want the arch to start, and draw the arch with a radius of 9 feet.

The radius of the arch is 9 feet.

The formula for calculating the radius of an arch is [tex]R = (width / 2) / sin(90°)[/tex].

Therefore, the radius of the arch is:

R = (18 ft / 2) / sin(90°) = 9 ft

To calculate the radius of the arch he needs to draw, the person can use the formula R = (width / 2) / sin(90°). In this case, the width of the arch is 18 feet, so the radius of the arch is 9 feet, calculated as R = (18 ft / 2) / sin(90°). The person will have to place the compasses 6 feet away from the point they want the arch to start, and draw the arch with a radius of 9 feet.

The equation of the plane passing through (0, -3,1) that is orthogonal to the planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7 is 16x - 8y + 8z = 32

We know that the equation of plane passing through point (x₁, y₁, z₁) is given by,

A(x - x₁) + B(y - y₁) + C(z - z₁) = 0

where, A, B, and C are direction ratios

In the question,  the plane passes through point (0, -3,1)

Let (x₁, y₁, z₁)  = (0, -3,1)

Using above formula the equation of the plane will be in the form,

A(x -0) + B(y - (-3))+C(z - 1) = 0            

Ax + B(y + 3)+C(z - 1) = 0                   ..........(1)

The required plane is orthogonal to the planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7.

So, their normal to the required plane would be perpendicular to the normal of both the planes.

The normal to the required plane is a cross-product of the normals of planes.

A cross-product of the normals of planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7 is 16i - 8j + 8k

So, the direction ratios,

A = 16, B = -8, C = 8

So equation (1) becomes,

16x - 8(y + 3) + 8(z - 1) = 0  

16x - 8y - 24 + 8z - 8 = 0

16x - 8y + 8z - 32 = 0 is the required equation of the plane

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Total number of employees = 140

Male:

Number of male = 65

Right-handed.

= Total number of right-handed - Female right handed

90 - 44 = 46

Left-handed.

= 65 - 46

= 19

Female:

Number of females.

= Total employees - Number of males

= 140 - 65

= 75

Right-handed.

= 75 - 31

= 44

Left-handed.

= 31

Now,

The frequency table.

                                            RH = 46

                                            LH = 19

           Male = 65

The best statistical test to be used is multiple linear regression analysis.

Multiple linear regression is a statistical method that allows you to examine the relationship between two or more independent variables (in this case, level of education, gender, and annual income of the student's parents) and one dependent variable (annual income and student loan debt).

It will help you determine how much of the variation in the dependent variable is explained by the independent variables, and the strength and direction of the relationships between the variables.

In this case, this test will allow us to determine the impact of a student's level of education, gender, and the annual income of their parents on their annual income and student loan debt while accounting for the possible confounding effect of the annual income of their parents on these variables.

Assuming all the workers employed at the beanbag factory are of equal ability, the beanbag factory invest in more equipment to address the diminishing marginal returns it experiences after the hire of its third worker. So the option B is correct.

It is assumed that all of the factory's employed employees have the same level of skill. Additionally, it must follow that if they are working to their maximum ability, they will be able to accomplish the same amount of work as before.

Since the third man was hired, the quantity of work the three of them have completed has decreased, making it clear that he is to blame for the diminishing returns.

Therefore, it seems sense to fire the individual since he is either not performing to his full capacity or encouraging other employees to do the same.

Answer:

To find the coordinates of Q, we can use the concept of proportional division of line segments.

Given that MQ:ON = 2:3, it means that the ratio of the length of MQ to ON is 2:3.

Let's first find the vector that represents the direction of MN, which is the vector pointing from M to N. We can find this by subtracting the coordinates of M from the coordinates of N:

(8,10) - (-12,-5) = (20, 15)

This is the vector <20,15>

Now, we can find the point Q, which is located two thirds of the way from M to N, by multiplying the vector <20,15> by 2/5 and adding the result to the coordinates of M:

Q = M + (2/5) * <20,15>

= (-12,-5) + (2/5) * <20,15>

= (-12,-5) + <8,6>

= (8,1)

So, the coordinates of Q are (8,1)

Answer: To find the average of daily income of the week, we need to find the total income of the week and divide it by the number of days in the week.

We know that the average daily income of the week is Rs 1,300 and we know that he earned Rs 2,000 on Saturday. To find the total income for the week, we can add the Saturday income to the average daily income for the 6 days.

Therefore, the total income for the week = Rs 1,300 (average daily income) x 6 (days) + Rs 2,000 (Saturday income) = Rs 7,800 + Rs 2,000 = Rs 9,800

To find the average daily income for the week, we divide the total income by the number of days in the week (7)

Average daily income = Rs 9,800 / 7 = Rs 1,400

Therefore, the average daily income of the plumber for the week is Rs 1,400.
