Using theoretical probability, the probability of selecting green ball is 3/11, not selecting green ball is 8/11, selecting orange ball is 6/11 and not selecting orange ball is 5/11.

In the given question,

A bag has 2 red, 3 green, and 6 orange balls.

So total number of balls = 2+3+6 = 11

We have to find the theoretical probability.

(a) We have to find the theoretical probability of selecting green ball.

P(G) = Total number of green balls/Total number of balls

P(G) = 3/11

Hence, the probability of selecting green ball is 3/11.

(b) Now we have to find the theoretical probability of not selecting green ball.

Except green ball there is having red and orange i.e.

Total remaining balls except green = 2+6 = 8

P(G) = Total number of balls except green balls/Total number of balls

P(G) = 8/11

Hence, the probability of not selecting green ball is 8/11.

(c) Now we have to find the theoretical probability of selecting orange ball.

P(G) = Total number of orange balls/Total number of balls

P(G) = 6/11

Hence, the probability of selecting green ball is 6/11.

(d) Now we have to find the theoretical probability of not selecting orange ball.

Except orange ball there is having red and green balls i.e.

Total remaining balls except orange = 2+3 = 5

P(G) = Total number of balls except orange balls/Total number of balls

P(G) = 5/11

Hence, the probability of not selecting orange ball is 5/11.

Answer: x=-y+9

Step-by-step explanation:

Answer:

the 4th one

Step-by-step explanation:

because we determined by Pythagorean theorem (the square root of 11)2 + 7 the power of 2 =

(the square root of 60)2 .....square root cancelled by power of 2

11 + 49 = 60

60 = 60

Answer:

c(x) = .19x + 32.50

Step-by-step explanation:

The cost depends on the number of copies.  The x value is the number of copies and the y value is the cost

c(x) = mx + b  We need to find the rate of change.

(50,42) (150.61)  The rate of change is the change in y over the change in x.

The y values are 61 and 42.  The x values are 150 and 50

[tex]\frac{61-42}{150-50}[/tex] = [tex]\frac{19}{100}[/tex] = .19

We also need the y intercept.  We will use the slope of .19 and the x and y values of one of the points. We could use either point, I am going to use the point (50,42)

y = 42

x = 50

m =.19

y=mx + b

42 = .19(50) + b

42 = 9.5 + b  Subtract 9.5 from both sides

32.50 = b

y = mx + b

y = .19x + 32.50 or

c(x) = .19x + 32.50

The range of six numbers is 8

According to the question,

Total number of Number = 6

Mean of number = 8

Ratio of numbers = 1 : 1 : 2 : 2 : 3 : 3

Let the common factor in numbers be "x"

Then , sum of number will be x + x + 2x + 2x + 3x +3x

=> 12x

Mean = sum of quantity / Number of quantity

8 = 12x / 6

Calculating the value of x,

12x = 48

=> x = 4

Substituting the value of x,

Number will be : 4 , 4 , 8 , 8, 12 , 12

Range = highest number - smallest number

We solved the system of equations graphically by graphing both equations and identifying the intercept.

The solution is:

(2.41, -1.03)

Here we have only one system of equations, which is:

-x²*y = 6

-x + 2y⁶ = 0

There are multiple ways of solving this, for example, we could isolate the variable "y" on the first equation:

y = -6/x^2

And replace that in the second equation, so we have an equation that only depends on x, but there is an easier way.

We can just graph both equations on the same coordinate axis and see in which points do the graphs intercept. Each intercept will be a solution of the system.

The graph can be seen below, there we can see that the only intersection point is at (2.41, -1.03), so that is the solution of the system.

Equation of circle:

The center is the radius long distance from the x- axis to left and y-axis up same distance, this makes it in the second quadrant.

So the coordinates of the center are:

The equation is:

Answer:

[tex](x+8)^2+(y-8)^2=64[/tex]

Step-by-step explanation:

Required conditions:

If the circle is tangent to both axes, its center will be the same distance from both axes.  That distance is its radius.

If the center of the circle is in quadrant II, the center will have a negative x-value and a positive y-value → (-x, y).

Therefore, the coordinates of the center will be (0-r, 0+r) where r is the radius.

If the radius is 8 units, then the center is (-8, 8).

[tex]\boxed{\begin{minipage}{4 cm}\underline{Equation of a circle}\\\\$(x-a)^2+(y-b)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(a, b)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}[/tex]

Substitute the found center and given radius into the formula to create an equation for the circle that satisfies the given conditions:

[tex]\implies (x-(-8))^2+(y-8)^2=8^2[/tex]

We could finish this question by applying the linar programming concept.

The profit function for the business is P(x) = 7x - 161

The number of units must be produced for the business to break even is

To find the formula of profit function, we have to understand first that profit is the remaining of revenue after being reduced by costs. Hence we could write this equation:

Profit = Revenue - Costs

Profit = R(x) - C(x)

If we create a new function P(x) that represent profit function, hence we could rewrite the profit function into:

P(x) = R(x) - C(x) ... (i)

Based on the question, we have both revenue and costs formulas as stated below:

R(x) = 24x ... (ii)

C(x) = 17x + 161 ...(iii)

We could subtitute equations (ii) and (iii) into equation (i) to get the profit formula:

P(x) = R(x) - C(x)

P(x) = 24x - (17x+161)

P(x) = 7x - 161 ... (iv)

To get the units must be produced, we have to understand that Break Even is a condition where the revenue is exactly the same of its costs, or when the profit is 0 (zero). Hence we could write the equation:

P(x) = 0 ...(v) --> Break Even

Then we would subtitute the equation (iv) into equation (v) to find the units must be produced (x) to achieve the break even.

P(x) = 0

7x - 161 = 0

7x = 161

Step-by-step explanation:

Take -1 as common form the denominator then cancel out the whole term i.e x²-x-1 and -1 remains.

The value of the functions f(-1), f(2), and f(5) are -2, 4, -2 respectively.

What is the function?

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable). The number of dependent variables for a function is 1 and the number of independent variable for a function is 1.

Given function is:

[tex]f(x)=\left\{\begin{matrix}-2 & \text{if } x \ne2 \\ 4 & \text{if } x=2\end{matrix}\right.[/tex]

The meaning of the above function is when x is not equal 2, then the value of f(x) is -2 and when x is equal 2, then the value of f(x) is 4.

The dependent variable is f(x). The independent variable is x.

So the value of f(-1) is -2 since x = - 1 ≠ 2.

So the value of f(2) is 4 since x = 2.

So the value of f(5) is -2 since x = 5 ≠ 2.
