Answer:

35%

Step-by-step explanation:

The percent error can be found using the

|Experimental value - Theoretical value| divided by |Theoretical value| and multiplied by 100.

I hope this helps

Here, the experimental probability is 1/4 and theoretical probability is 1/18.Then the percent difference between the theoretical probability and the experimental probability is 56%.

The probability is a measure of chances that an event to take place.

Given that,

red marbles = 3

blue marbles =1

yellow marbles = 2

Then.

theoretical probability of selecting a blue marble followed by a yellow marble is:

P(blue and yellow) = P(blue) x P(yellow) = (1/6) x (2/6) = 1/18

Since the marbles are replaced after each draw, the probability of this event is the same for every draw.

The experimental probability of selecting a blue marble followed by a yellow marble after 40 attempts is:

(3/6) x (2/6) x (40 attempts) = 10

Therefore, the experimental probability is 10/40 = 1/4

The percent difference between the theoretical probability and the experimental probability is:

| (experimental probability - theoretical probability) / theoretical probability | x 100%

= | (1/4 - 1/18) / (1/18) | x 100%

= 0.583 x 100%

= 58.3%

Therefore, the percent difference between the theoretical probability and the experimental probability is approximately 58.3%, which is closest to the option 56%.

Hi there!

[tex]\large\boxed{\text{ sum = 180(n - 2)}}[/tex]

This is the formula for finding the sum of interior angles for a polygon with a number of sides "n".

We can also prove this from the table:

Triangle ⇒ 3 sides: 180(3 - 2) = 180°

Quadrilateral ⇒ 4 sides: 180(4 - 2) = 360°

Pentagon ⇒ 5 sides: 180(5 - 2) = 540°

...And so forth. We can write this as for any polygon with "n" sides:

180(n - 2) = sum (°)

Answer:

$356

Step-by-step explanation:

To solve this problem, use this: (200 * 3.78) - (200 * 2)

(200 * 3.78) - (200 * 2)

200 * 3.78 is the same as 2 * 378, which is 756.

756 - (200 * 2)

200 * 2 is the same as 4 * 100, which is 400.

756 - 400

Subtract 400 from 756 to get 356.

YW = [tex]\sqrt{1322}[/tex]

ZX = ([tex]\sqrt{1322}[/tex]) / 2

VX = [tex]\sqrt{1322}[/tex]

Step-by-step explanation:

[tex]YW^{2}[/tex] = [tex]19^{2}[/tex] + [tex]31^{2}[/tex]

[tex]19^{2}[/tex] + [tex]31^{2}[/tex] = 1322

ZX = YW/2 = VX/2

 Measures of the different sides of the rectangle will be,

YX = 31 units

WX = 19 units

VW = 36.36 units

ZX = 18.18 units

VX = 36.36 units

Quadrilateral VWXY is a rectangle.

Properties of a rectangle,

YX = VW = 31 units

VY = WX = 19 units

By applying Pythagoras Theorem in right triangle ΔWXY,

(Hypotenuse)² = (Leg 1)² + (Leg 2)²

(WY)² = (WX)² + (XY)²

YW = [tex]\sqrt{19^2+31^2}[/tex]

      = [tex]\sqrt{1322}[/tex]

      = 36.36 units

ZX = [tex]\frac{1}{2}(YW)[/tex]

     = [tex]\frac{1}{2}(36.36)[/tex]

     = 18.18 units

VX = YW = 36.36 units

Answer:

377/29

Step-by-step explanation:

this is the answer for plato, i took the test btw

For the given value of sin, the value of cosΘ will be 0.73.

A right-angle triangle's sides, angles, and relationship to each other are the subject of the mathematical discipline of trigonometry. The pair ratio of a right-angled triangle is known as the trigonometric ratio.

It is given that, sinΘ= -4√29 / 29

Θ=sin⁻¹(-4√29 / 29)

Θ= -0.74

The value of cosΘ is obtained as,

=cosΘ

=cos( -0.74)

=0.73

Thus, the value of cosΘ will be 0.73.

The value of x = -2

Step-by-step explanation:

Given equation:

2x + 4 = 0

Find:

The value of x

Computation:

We know that given equation 2x + 4 = 0 is a liner equation with only one variable.

So, we can solve this by elimination method

2x + 4 = 0

Step 1 :

Subtract 4 from both side

2x + 4 - 4 = 0 - 4

2x = -4

Divide 2 from both side

2x / 2 = -4 / 2

x = -2

The value of x = -2

Answer: (x + 4)^2 + (y - 3)^2 = 50

Step-by-step explanation:

Given: x^2 + y^2 + 8x - 6y - 25 =0, which the general form of the circle.

Solution:

Complete the square formula: (x - h)^2 + (y - k)^2 = r^2

Group similar term together on the left side of the equation and move the constant to right side of the equation ( remember to change the sign of the constant.

x^2 + y^2 + 8x - 6y - 25 =0

x^2 + 8x + y^2 - 6y = 25

Complete the Square: (x^2 + 8x + _____) + (y^2 - 6y + _____) = 25

Take half of the coefficient of the linear term for each variable, square the quotient, and add the answer to both side of the equation.

half of the coefficient of the linear term: ( 8/2)^2 = 16 and (-6/2)^2 = 9

(x^2 + 8x + 16) + (y^2 - 6y + 9) = 25 + 16 + 9

Each quality is a trinomial square and need to be factored

(x + 4)^2 + (y - 3)^2 = 50

Answer:

Step-by-step explanation:

There are no real roots and the graph contains point (2,5). Notice it is in vertex form. So there must be a point at x = 2 and y = 5. However, if it is the vertex and it opens upwards, that means it cannot intersect the x axis. So 2 and 4 are the correct answers I believe.
