Answer: 2,-2 is the real asnwer!

Answer:

The probability that she takes out a red marble the first time and a green marble the second

P(E₁ ∩ E₂ ) = P(E₁) P(E₂)

                [tex]= \frac{5 X 5}{20} = \frac{25}{20} = \frac{5}{4} ways[/tex]

Step-by-step explanation:

Step(i):-

Given a bag of marbles contains 5 red marbles, 5 green marbles, 5 yellow marbles and 5 blue marbles

Total balls n(S) = 5red +5green +5yellow + 5blue  =  20

Total numbers cases

                         n(S) = 20C₁ = 20 ways

Step(ii):-

Let E₁ be the event of drawing one red marble from 5 red balls

                       n(E₁) = 5C₁

Let E₂ be the event of drawing one green marble from 5 green balls

                       n(E₂) = 5C₁

The two events are independent events

P(E₁ ∩ E₂ ) = P(E₁) P(E₂)

                =[tex]= \frac{5 X 5}{20} = \frac{25}{20} = \frac{5}{4} ways[/tex]

Final answer:-

 The probability that she takes out a red marble the first time and a green marble the second

P(E₁ ∩ E₂ ) = P(E₁) P(E₂)

                =[tex]= \frac{5 X 5}{20} = \frac{25}{20} = \frac{5}{4} ways[/tex]

Answer:

  y = -1/3x +(7 2/3)

Step-by-step explanation:

The 2-point form is a good place to start.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (6 -8)/(5 -(-1))(x -(-1)) +8

  y = -2/6(x +1) +8

  y = -1/3x +(7 2/3)

-3/8 = x

Step-by-step explanation:

90% sure this is correct but my simple math may be wrong

Answer: x=9

Step-by-step explanation:

x^2-8x-9=0...

we can simplify this by adding 9 to each side... so it turns into this: x^2-8x=9

Then, we can turn x^2 to x*x because we know that anything to the power of two is itself multiplied by itself. So our new equation will be this:

x*x-8x=9

Now we know x has to be 9 because 8 is 1 less than 9. Therefore, our answer would be x (9)...

Let’s test this out... first, let’s substitute x with the number 9:

9^2-8*9-9=0. Simplify this:

81-72-9=0. We can then simplify furthers and we get:

0=0. This means that the equation is true

Answer:

  the n-th root of the ratio of ending to starting values, less 1

Step-by-step explanation:

When I have starting and ending values over a time period, I usually use those directly in the exponential equation. If you're asked for a percentage growth rate, then you have to convert the growth factor to a growth rate.

__

The exponential equation can be written ...

  f(t) = (initial value) × ((final value)/(initial value))^(t/(time period))

In your example case, this would be ...

  f(t) = 2 × (20/2)^(t/18)

  f(t) = 2(10^(t/18)) . . . . . . simplified

__

To convert this to the form ...

  f(t) = 2(1 +(growth rate))^t

recognize that ...

  (1 +(growth rate)^t = (10^(1/18))^t

So, you need to find the value of ...

  10^(1/18) = 10^(1/18) ≈ 1.13646 = 1 + 13.646%

Then the growth rate is about 13.6% each week.

__

Sometimes, you want to use this in the form ...

  f(t) = (initial value)×(1 + (growth rate))^t

and sometimes you want the form ...

  f(t) = (initial value)×e^(kt)

When you solve for k, you find it is ...

  k = ln(1 + (growth rate)) . . . . . . . . where ln(x) is the natural logarithm of x

Here, that is ...

  k = ln(10^(1/18)) = ln(10)/18 ≈ 0.12792

__

Your final growth equation could be any of ...

  f(t) = 2(10^(t/18)) . . . . . . . my personal favorite, as no rounding is involved

  f(t) = 2(1.13646^t)

  f(t) = 2e^(0.12792t)

Answer:

.25+.25+.25+.25+.25

Answer:

3/64

Step-by-step explanation:

The distance from C to G is 32 units and this can be determined by using the properties of the circumcenter of a triangle.

Given :

AG = 4x + 16

BG = 10x - 8

The following steps can be used in order to determine the distance from C to G:

Step 1 - Remember in the given diagram G is the circumcenter because all the perpendicular bisector intersects at point G.

Step 2 - Now, if G is the circumcenter then:

AG = BG = CG

Step 3 - Now, substitute the value of AG and BG in the above expression.

4x + 16 = 10x - 8

24 = 6x

x = 4

Step 4 - Now, use the relation BG = CG in order to determine the value of CG.

10(4) - 8 = CG

CG = 32

Answer:

(-3,5) (6,2) (Plug in these points into (y2-y1)/(x2-x1) to find the slope)

2-5/6-(-3)

-3/9

-1/3 is the slope

y - y1 = m(x -x1) (this is point slope form)

y - 5 = -1/3 (x +3) (you plug in the x &y values from the first set of coordinates)

y -5 = -1/3x -1  (you get to slope intercept form by solving from point slope)

y = -1/3x +4 (this is slope intercept form)

Answer:

x-intercept(s):  ( 0 , 0 )

y-intercept(s):  ( 0 , 0 )

Explanation:

To find the x-intercept, substitute in  0  for  y  and solve for  x .

To find the y-intercept, substitute in  0  for  x  and solve for  y .

Answer:

y = 1/3x - 1

Step-by-step explanation:

We can put this information in slope intercept form [ y = mx + b ], where m = slope and b = y-intercept. We are given both the slope and y-intercept so m = 1/3 and b = -1. Put this into the formula; y = 1/3x - 1
