what is the mean age of the 8 golfers

Answers

Answer:

27.25 Years Old

Step-by-step explanation:

Find the total age of the 17 golfers.

52(17) = 884

Find total age of the 9 golfers.

9(74) = 666

Subtract.

884 - 666 = 218

Divide by the 8 golfers.

 which equation represents the line that passes through the points (3, 7) and (-1, -1)?

Answers

points: (3, 7) and (-1, -1)

slope (m) :

[tex]\sf \dfrac{y_2-y_1}{x_2-x_1}[/tex]

========

[tex]\hookrightarrow \dfrac{-1-7}{-1-3}[/tex]

[tex]\hookrightarrow \dfrac{-8}{-4}[/tex]

[tex]\hookrightarrow 2[/tex]

Equation:

[tex]\sf y-y_1 = m(x-x_1)[/tex]

==============

[tex]\rightarrow \sf y-7 = 2(x-3)[/tex]

[tex]\rightarrow \sf y = 2x-6+7[/tex]

[tex]\rightarrow \sf y = 2x+1[/tex]

Answer:

[tex]y = 2x- 1[/tex]

Step-by-step explanation:

To determine which equation passes through the points (3, 7) and (-1, -1), we need to determine the slope of the equation. Then, we shall use point slope form to determine the equation of the line.

Determining the slope of the line:

[tex]\text{Slope} = \dfrac{\text{Rise}}{\text{Run} } =\dfrac{\text{y}_{2} - \text{y}_{1} }{\text{x}_{2} - \text{x}_{1} }[/tex]

Substituting the points in the slope formula:

[tex]\text{Slope} =\dfrac{-1 - 7 }{-1- 3 }[/tex]

Simplifying the slope:

[tex]\text{Slope} =\dfrac{-1 - 7 }{-1- 3 }[/tex]

[tex]\text{Slope} =\dfrac{-8}{-4 } = 2[/tex]

Determining the equation of the line:

We shall use point slope form to determine the equation of the line.

[tex]\text{Point slope form:} \ y - y_{1} = m(x- x_{1} )[/tex]

Substitute the slope and the coordinates of any two points stated above.

[tex]y -7= 2(x- 3 ) \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\text{Using the point (3,7)}][/tex]

Simplify the equation and organize it to slope intercept form:

[tex]y -7= 2x- 6[/tex]

[tex]y = 2x- 6 + 7[/tex]

[tex]y = 2x+ 1[/tex]

5               1

6               1

Because the median is 2, and the data points to the left and right are not symmetrical, the data set is not symmetrical.

From the given data set

4 has a frequency of 2

5 has a frequency of 1

Then the range of the dot plot can be from zero to seven because it covers the given data set.

A web browser is open on your computer screen. The area of the browser window is 24 square inches. Find the length of the browser window x. The browser covers 3/13 of the screen. What are the dimensions of the screen?

Answers

We will see that the length of the browser window is 4.9 inches, and the screen is a square of sidelength 10.2 in

How to find the length of the browser window?

We know that the area of the browser window is 24 in^2, we will assume that the window is a perfect square, then the area is equal to the square of the length x, we have:

x^2 = 24 in^2

x = √(24 in^2) = 4.9 in

How to get the dimensions of the screen?

We know that the browser covers 3/13 of the screen, so the area of the screen is 13/3 times the area of the browser:

A = (13/3)*24 in^2 = 104 in^2

Again, if the screen is square of sidelength s, we have:

s^2 = 104 in^2

s = √(104 in^2)  = 10.2 in

If the first marble drawn is yellow, that happens with a probability of 8/18

So the important thing to note is that now there are 17 marbles,

Now a red marble is drawn. We didn't replace the yellow.

There are 6 red marbles.

So the chances of getting a red marble is 6/17

This is an arithmetic series with first term 18 and common difference 3.

The nth term is

18 + 3(n - 1)

The 32nd term is the number of seats in the 32nd row:

The quadratic regression equation of company X sales would have a degree of 2

The quadratic regression equation is y = -507.61x^2 +23372.94x -170697.85The profit for selling at $22.75 is $98316.63

The quadratic regression equation

To determine the quadratic regression equation, we make use of a graphing calculator

From the graphing calculator,we have the following calculation summary

a = -507.61b = 23372.94c =  -170697.85

A quadratic regression equation is represented as:

y = ax^2 + bx + c

So, we have:

y = -507.61x^2 +23372.94x -170697.85

Hence, the quadratic regression equation is y = -507.61x^2 +23372.94x -170697.85

The profit for selling at $22.75

This means that:

x = 22.75

So, we have:

y = -507.61 * 22.75^2 + 23372.94 * 22.75 -170697.85

Evaluate

y = 98316.63
