The probability of selecting red marble is 0.444.

Probability is calculated using the formula :

Probability = number of favourable outcomes ÷ total number of outcomes

Number of favourable outcomes = number of red marbles in box

Number of favourable outcomes = 8

Total number of outcomes = total number of marbles

Total number of outcomes = 8 + 4 + 6

Total number of outcomes = 18

Keep the values in formula of probability to find the probability of selecting red marble

Probability = 8 ÷ 18

Performing Division by 2

Probability = 4/9

Representing in decimal round to three decimal places = 0.444

Hence, the probability of selecting red marble is 0.444.

Suppose $2000 is deposited in a bank account with an annual compound interest rate of 3%. After two years, we will have accumulated 121.80 in interest on your initial 2000 deposit.

Compound interest is, to put it simply, interest that is earned on interest. Compound interest is interest that is earned on both the initial principal and interest that builds up over time in a savings account.

There may be a difference in the timing of when interest is paid out and compounded. For instance, interest on a savings account may be paid monthly but compounded daily. The account balance plus any interest that has accrued but has not yet been paid out are used by the bank to determine your daily interest earnings.

For the above question:

Account Balance = Principal x (1 + interest rate (decimal))^number of the years. With given information this is:  [tex]2000 (1.03)^2[/tex] = 2,121.80.  So we will earn 121.80 in interest after the 2 years on your original 2000 deposit.

Answer:

last one h babysat for 6 hours

1) A heart is equal to 5 units, a star to 13 units and a square to 20 units.

2) A star is equal to 66 units, a circle to 30 units and a triangle to 14 units.

Herein we find two case of systems of elements which have to be solved on the fact that each element represents a quantity. Now we proceed to represent each system:

Case 1

x - Heart

y - Star

z - Square

The algebraic representation of the system is shown below:

18 - x = y                      (1)

2 · x = 10                     (2)

z - y - 2 = x                  (3)

By (2):

x = 5

By (1):

y = 18 - 5

y = 13

By (3):

z = x + y + 2

z = 5 + 13 + 2

z = 20

Case 2

x - Triangle

y - Star

z - Circle

The algebraic representation of the system is shown below:

2 · x = 28                   (1)

80 - x = y                   (2)

y + x - z = 50             (3)

By (1):

x = 14

By (2):

y = 80 - 14

y = 66

By (3):

z = y + x - 50

z = 66 + 14 - 50

z = 30

By taking the quotient between the total debt and the number of people, we conclude that the debt per person is $2,622

To find the amount of debt per person, we need to find the quotient between the total amount of debt and the number of people.

Here the total debt is:

$6.39 billion = $6.39*10^9

And the total number of people is:

2.437 million = 2.437*10^6

Then the quotient is:

Q = ($6.39*10^9)/( 2.437*10^6) = $2.622*10^3

The debt per person is:

The equation that can be used to find the y-intercept of the line is

b = y - mx, and the y-intercept for this equation will be -12

In this question, It is given that a line passes through a given point (1,-8), and the slope of the line is given 4. We know the equation of Slope-point form : (y - y₁) = m(x - x₁), Where m = slope = 4 and (x1,y1) = (1,-8)

Now, putting these values into the slope-point form equation, We get :

            => (y - y₁) = m(x - x₁)

            => (y - (-8) = 4(x - 1)  => (y +8) = 4x -4

            => y = 4x -12          ---> Equation (1)

We got the slope-intercept form for the following situation.

We can find out the y-intercept value by comparing the

            => y = mx + b to Equation (1).

            => b = -12

Hence, b = y - mx will be used to find out the y-intercept and the y-intercept for this line will be -12

Figure B is similar but not congruent to Figure A.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

Answer:

LK = 7

Step-by-step explanation:

We are using segment addition

NM + ML + LK = NK

x-6  + 9 +  2x-19  = 23

Combine like terms

x+2x   -6+9-19 = 23

3x -16 = 23

Add 16 to each side

3x-16+16 = 23+16

3x = 39

Divide each side by 3

3x/3 = 39/3

x = 13

We want to find the value of LK

LK = 2x-19

     =2(13) -19

     = 26 -19

    = 7

Answer:

[tex]\sf \: LK = 7 \: units[/tex]

Step-by-step explanation:

It's clear that,

[tex] \sf \: NM + ML + LK = NK[/tex]

Given that,

NM ---> x - 6

ML ---> 9

LK ---> 2x - 19

NK ---> 23

First, let us find the value of x using these values.

[tex] \sf \: NM + ML + LK = NK \\ \sf x - 6 + 9 + 2x - 19 = 23 \\ \sf \: combine \: like \: terms. \\ \sf \: 3x - 16 = 23 \\ \sf3x = 23 + 16 \\ \sf3x = 39 \\ \sf \: divide \: both \: sides \: by \: 3. \\ \sf \: x = 13[/tex]

And now we have to find out the length of LK.

As we mentioned before,

LK = 2x - 19

So, to find the length of LK, we have to replace x with 13 and solve the equation.

Let us solve now.

[tex] \sf \: LK = 2x - 19 \\ \sf \: LK = 2 \times 13 - 19 \\ \sf \: LK = 26- 19 \\ \sf \: LK = 7 \: units[/tex]

Since the able that need to be found lies at 25 units side, the base side will be that only.

So, we get that:

Base side = B = 25 units

Perpendicular side = P = 10 units

We know that:

tan θ = P / B

tan θ = 10 / 25

tan θ = 2 / 5

Acceleration of the ball is 10 [tex]m/s^{2}[/tex].

The relation between initial velocity , final velocity , acceleration and time can be written as,

v = u + at

Here, v is the final velocity, u is the initial velocity, a is the acceleration and t is the time

Time taken by ball to reach the ground = t = 2 seconds.

As it starts from rest , initial velocity of ball = u = 0 m/s.

Final velocity of ball = v = 20m/s.

v = u + at                                                               equation 1

Put value of v = 20m/s , u = 0m/s and t = 2 seconds in equation 1.
