We require both to ascertain whether the findings are independent, this criterion is applied.

Statistics frequently employs the binomial distribution as a discrete distribution. When compared to a binomial distribution, the normal distribution is continuous. The chance for 'x' success of an investigation in 'n' trials is represented by the binomial distribution.

As per the given information in the question,

The normal distribution can be used to approximate the binomial distribution. The situation when performing a normal approximation is as follows:

np ≥ 10 and,

np(1 - p) ≥ 10

This criterion is used to determine whether the results are independent.

The solution of the given system of equation is (3, 2).

In the given question we have to find the solution to the system of equations:

y = 4x − 10 and y = 2

We can solve the system of equation using the substitution method.

In substitution method we have to put the the value of one variable from one equation to the other equation.

We have to equations:

y = 4x − 10........................(1)

y = 2...................................(2)

Now putting the value of y from the equation 2 in equation 1

2 = 4x − 10

Add 10 on both side, we get

4x = 12

Divide by 4 on both side, we get

x = 3

Now putting the value of x in equation 1

y = 4(3) − 10

y = 12 − 10

y = 2

Hence, the solution of the given system of equation is (3, 2).

A dilation is a type of transformation causes the image to be larger or smaller than the pre-image.

A dilation is a type of transformation that changes the size of a figure without changing its shape. Dilations can make a figure larger or smaller.

In a dilation, the original figure is called the preimage. The dilated figure is called the image. Figures are dilated from a fixed point, called the center of dilation.Dilations also scale all sides of a figure by the same factor. As a result, dilations preserve angle measures and the ratio between corresponding parts.When dilating a figure, the different parts of the figure are multiplied by the scale factor.

In a dilation, the scale factor refers to the ratio between the corresponding sides of the preimage and the image. Therefore, the scale factor, k, can be calculated by dividing the length of one part in the image with the corresponding part in the preimage. The length of the preimage part should always be in the denominator as it belongs to the original figure.

A dilation is a type of transformation causes the image to be larger or smaller than the pre-image.

The rational roots of the given polynomial are +/- 1, +/- 2, +/- 3, +/- 4, +/- 6, +/- 12, +/- 1/2, +/- 1/4, +/- 1/5, +/- 1/10, and +/- 1/20.

To find the rational roots of the polynomial, we can use the Rational Root Theorem. This theorem states that if a polynomial of the form a_n*x^n + a_{n-1}x^{n-1} + ... + a_1x + a_0 has a rational root, then that root must be of the form p/q, where p is a divisor of a_0 and q is a divisor of a_n.

In this case, the polynomial is

f(x) = 20x^4 - 8x^3 - x^2 + 12x,

so a_0 = 12 and a_4 = 20. The divisors of 12 are 1, 2, 3, 4, 6, and 12. The divisors of 20 are 1, 2, 4, 5, 10, and 20. Therefore, the possible rational roots of the polynomial are

p/q = +/- 1, +/- 2, +/- 3, +/- 4, +/- 6, +/- 12, +/- 1/2, +/- 1/4, +/- 1/5, +/- 1/10, and +/- 1/20.

We can then test each of these values to see if they are actually roots of the polynomial. If a value is a root, then substituting it into the polynomial will result in a value of 0.

Therefore, the rational roots of the given polynomial are +/- 1, +/- 2, +/- 3, +/- 4, +/- 6, +/- 12, +/- 1/2, +/- 1/4, +/- 1/5, +/- 1/10, and +/- 1/20.

Bisection in geometry is the division of an object into two equal or congruent halves, typically by a line, which is subsequently referred to as a bisector. The segment bisector and the angle bisector are the two forms of bisectors that are most frequently used. 

LMO+NMO = LMN,

x+34 + NMO = 6x-28

But, MO bisects LMN, so LMO=NMO

x+34 + x+34 = 6x-28

2x+68 = 6x-28

4x = 96

x = 24

That would makem it

The roots of the quadratic equation 2x² + 5x - 2 = 0 are -2.7 and 1.3.

The quadratic equation is 2x² + 5x - 2 = 0.

We can solve this equation using the Quadratic Formula:

x = [-b ± Â√(b² - 4ac)] / 2a

Where a = 2, b = 5, and c = -2.

Substituting these values into the formula, we get:

x = [-5 ± Â√(5² - 4(2)(-2))] / 2(2)

x = [-5 ± Â√41] / 4

x = [-5 ± Â√41] / 4

x = [-5 ± 6.4] / 4

x = -2.7 or 1.3

step 2: Multiply the answer by 10

step 3:  

To solve this equation, use the distributive property to rewrite it as 4x - 2y = 12. Then, solve the equation using either addition or subtraction.

To solve the equation 4x 2y = -12, the first step is to use the distributive property to rewrite the equation as 4x - 2y = 12. This allows us to solve the equation using either addition or subtraction. If we choose to use addition, we can add 2y to both sides of the equation to get 4x + 2y = 12. We can then subtract 2y from both sides to get 4x = 12 - 2y. Dividing both sides of the equation by 4 gives us the solution x = (12 - 2y)/4. If we choose to use subtraction, we can subtract 2y from both sides of the equation to get 4x - 2y = 12. We can then add 2y to both sides to get 4x = 12 + 2y. Dividing both sides of the equation by 4 gives us the solution x = (12 + 2y)/4. In either case, the solution is x = (12 ± 2y)/4.

Addition:

4x + 2y = 12

4x = 12 - 2y

x = (12 - 2y)/4

Subtraction:

4x - 2y = 12

4x = 12 + 2y

x = (12 + 2y)/4

angles in a triangle are 180

180-130=50

Answer:50 degrees

Step-by-step explanation: The 105degrees angle forms a supplementary angle with the missing degrees in the triangle

so the missing value which is not requested is 180degrees-105 degrees=75 degrees

No we have two angles inside the triangle. We can now work out the missing angle for x

Answer: -6

Step-by-step explanation:

If x:(x+3) = 2:3, we can set up the following equation:

x / (x+3) = 2/3

Next, we can multiply both sides of the equation by 3 to get rid of the fraction on the right side:

3 * (x / (x+3)) = 3 * (2/3)

This gives us:

x / (x+3) = 2

Finally, we can multiply both sides of the equation by (x+3) to get rid of the fraction on the left side:

x = 2 * (x+3)

We can then solve for x by rearranging the terms on the right side of the equation:

x = 2x + 6

Subtracting 2x from both sides gives us:

x - 2x = 6

This simplifies to:

-x = 6

Finally, we can divide both sides of the equation by -1 to solve for x:

x = -6

Therefore, x = -6.
