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.

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.

Answer:

Step-by-step explanation:

The maximum that the company can expect for returned items is C. $5972.65

How to calculate the value?

From the information, the average daily profit of an electronics store is $31,435 and the company estimates that 15% is lost each day to returns, with a margin of error of ±4%.

In a random survey sample, a margin of error is a statistical measurement that takes into account the discrepancy between actual and anticipated findings. Simply said, you may determine the degree of unpredictability in data and research results using the margin of error.

The maximum the company can expect for returned items will be:

= (15% + 4%) × Profit

= 19% × $31,435

= 0.19 × $31,435

= $5972.65

The expression 2(3+4) can be expressed as 2×7

A factor is a number that divides another number, leaving no remainder. In other words, if multiplying two whole numbers gives us a product, then the numbers we are multiplying are factors of the product because they are divisible by the product.

For example the factors of 8 are 1,2,4,8. i.e 1×8=8, 2×4= 8

considering the expression 2(3+4), the value is 2(7)= 14

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.

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

We know that the ratio of yes votes to no votes was 4 to 3, so from each 7 votes, 4 are yes and 3 are no.

Then if we take the total number of votes, and we multiply it by (4/7), we will get the total number of yes votes.

In this case we know that the total number of votes is 6706, then the number of yes votes is:

The slope of the line that passes through the points (1, 6) and (1, 31) is, ∞

Slope is a ratio of change in y-coordinate w.r.t. change in x-coordinate. The net change in y coordinate is written as, Δy and the net change in x coordinate is written as, Δx.

So formula for the slope is,

m = change in y coordinate/change in x coordinate = Δy/Δx = y₂-y₁/x₂-x₁

Given that,

the line passes through the points, (1,6) and (1,31)

So, we can calculate slope for the line by using formula when two are given,

m =  y₂-y₁/x₂-x₁

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
