A bag contains 5 red marbles, 6 blue marbles, and 9 green marbles. About how many red marbles would you expect to draw if you did 100 draws?

Answers

Answer 1

Answer: 25

Step-by-step explanation: Add all of the marbles, which is 20 in total, it is 5/20, so the ratio is 5:20

5:20 is 10:40, 15:60, 20:80, and 25:100

The answer is correct because 5:20 is 25% and 25/100 is also 25%

The solution of the graphed system of equations y = -x² + x + 2 and y = -x + 3 is (1,2)

How to solve the equations?

The system of equations is given as:

y = -x² + x + 2

y = -x + 3

From the graph in the complete question, we have the following point of intersection between the equations

(x,y) = (1,2)

The point of intersection between the equations is the solution

Hence, the solution of the graphed system of equations is (1,2)

Describe the transformations necessary to transform the graph of f(x) into that of g(x).

Answers

Using translation concepts, it is found that the transformations necessary to transform the graph of f(x) into that of g(x) are given as follows:

Reflection over the y-axis. Horizontal stretch by a factor of 2.Shift left 3 units.Reflection over the x-axis.Shift down 1 unit.

What is a translation?

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

The original function f(x) is given by:

[tex]f(x) = \sqrt{x}[/tex]

The transformations are as follows:

Inside the domain, the function was multiplied by -1/2 and 3 was added. Hence the function was reflected over the y-axis, horizontally stretched by a factor of 2 and shifted left 3 units.Outside the domain, in the range, the function was multiplied by -1 and 1 was subtracted, hence the function was reflected over the x-axis and shifted down one unit.

The equation that models the exponential decline is y = 46348587109809610(0.9861)ˣ if the population over the past 20 years is provided.

What is the line of best fit?

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

Let's suppose the equation that models the exponential decline is:

[tex]\rm y = a(b^x)[/tex]

From the data given, we can calculate the value of a and b:

a = 46348587109809610

b = 0.9861

y = 46348587109809610(0.9861)ˣ

Thus, the equation that models the exponential decline is y = 46348587109809610(0.9861)ˣ if the population over the past 20 years is provided.

If (x+42)+3x = 90 what is x

Answers

Answer:

X=12

Step-by-step explanation:

First, take the term out parenthesis being careful to manage the sign of individual term carefully :

x+42+3x=90

Next , subtract 42 from each side of the equation to isolate the x term while keeping equation balance :

x+42-42+3x=90-42

x+0+3x=48

x+3x=48

(1+3)x=48

4x=48

Now, Divide both side of equations by 4 to slove of x while keeping equation balance :

4x/4=48/4

x=12

Solve the system with elimination.
x - 2y = 4
3x + y = 6
? ]

Answers

[tex]\bold{FULL ANSWER:}[/tex]
x = 16/7, y = -6/7

For elimination I will multiply the first equation by -3 to get the x to cancel

x - 2y = 4 --> -3x + 6y = -12

Now we bring back the other equation and treat it like an addition problem:

-3x + 6y = -12
3x + y = 6
+———————
7y = -6

y = -6/7

To get x we will use this y-value and plug it into one of the equations:

3x + y = 6,
3x + (-6/7) = 6
3x - 6/7 = 6
3x = 48/7
x = 16/7

So the solution is x = 16/7, y = -6/7, and if you are ever unsure you can put both of these values into both system of equations to see if the equations are true.

speed = 0.20 m/s

What is the speed of wave?

The wave equation is a linear second-order partial differential equation which describes the propagation of oscillations at a fixed speed in some quantity y.

The wave equation is given by:

we have,

angular number, k=20

and, angular frequency, ω=4.0 rad/s.

Thus, the speed of the wave is

so, when going from (-2, 3) to (-3, 1)

y changes by -2 (from 3 to 1).

What is the vertex of the quadratic function f(x) = (x-8)(x - 2)?

Answers

Answer:

The vertex is (5, -9).

Step-by-step explanation:

One way of approaching this problem consists of finding the roots.  Seet the quadratic equal to zero and solve for x:  {2, 8}.

The axis of symmetry is exactly halfway between 2 and 8:  x = 5.

Now find the y-component of the vertex by evaluating f(5):

f(5) = (5 - 8)(5 - 2) = -9

The vertex is (5, -9).  This is the minimum value of the function.  The graph of this quadratic opens up.
