Answer:

∠ AED = 92°

Step-by-step explanation:

The chord- chord angle ADE is half the sum of the arcs intercepted by the angle and its vertical angle, that is

∠ AED = \(\frac{1}{2}\) ( arc AD + arc BC )

           = \(\frac{1}{2}\) (146 + 38)°

           = \(\frac{1}{2}\) × 184°

           = 92°

Answer:

length = 15

Width = 9

Step-by-step explanation:

In a rectangle opposite sides are equal.

5x - y- 8 =3x +5y + 4

5x - 3x  -y - 5y = 4 + 8

2x - 6y = 12

Divide the entire equation by 2

x  - 3y = 6  --------------(I)

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

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

x + 7y = 1 -------------(II)

Multiply equation (II) by (-1)

(I)            x - 3y = 6

(II)*(-1)    -x - 7y = -1   {Now add. 'x' will be eliminated}

                  -10y= 5

                      y = 5/(-10)

                     y = -0.5

Plugin y = -0.5 in equation (I)

x - 3*(-0.5) = 6

x  + 1.5 = 6

        x = 6 - 1.5

        x = 4.5

Length = 5x - y - 8

           = 5*4.5 - (-0.5) - 8

           = 22.5 + 0.5 - 8

            = 23 - 8

Length = 15

Width = 2x - 6y - 3

         = 2*4.5 - 6*(-0.5) - 3

         =  9 + 3 - 3

Width = 9

The value of the test statistic is -1.5.

Test statistic:

A test statistic is a statistic used in statistical hypothesis testing. A hypothesis test is typically specified in terms of a test statistic, considered as a numerical summary of a data set that reduces the data to one value that can be used to perform the hypothesis test.

The formula for test statistic:

Test statistic = z = \(\frac{P - P_{0} }{\sqrt{\frac{P_{0( 1 -P_{0} } }{n} } }\)

A sample of patients n = 150

Patients insured =x = 75

P = x/n

  = 75/ 150

  = 1/2

  = 0.5

\(P_{0}\) = 56/100

    = 0.56

Putting the values we get:

z = \(\frac{0.5 - 0.56}{\sqrt{\frac{0.56( 1- 0.56)}{150} } }\)

  = \(\frac{-0.06}{\sqrt{0.00164} }\)

  =   \(\frac{-0.06}{0.04}\)

  = - 1.5

Therefore the test statistic is -1.5.

To determine the size of the weight matrix for the given convolutional neural network (CNN), we need to consider the number of units in the first layer and the dimensions of the input grayscale images.

In a CNN, the weight matrix is used to perform the convolution operation, which involves applying filters to the input images. Each unit in the first layer corresponds to a specific filter or kernel. The size of the weight matrix will depend on the number of units in the layer and the dimensions of the filters.Let's assume that the number of units in the first layer is N, and the input grayscale images have pixel dimensions MxM. In this case, the weight matrix will have dimensions N x (K x K), where K represents the kernel size. Each row of the weight matrix corresponds to the weights associated with a specific unit in the first layer.The number of columns in the weight matrix is determined by the kernel size, which is typically a square matrix.

The values in the weight matrix represent the learnable parameters of the CNN.  By adjusting the weights in the matrix, the CNN can learn to extract meaningful features from the input images and make accurate predictions. Overall, the size of the weight matrix for the given CNN is N x (K x K), where N is the number of units in the first layer, and K is the kernel size. The rows of the weight matrix correspond to the units in the first layer, and the columns represent the weights associated with each pixel in the kernel used for convolution.

The quadratic equation that has a discriminant of 0 is x^2 - 4x + 4 = 0.

The discriminant of a quadratic equation is calculated using the formula b^2 - 4ac, where 'a', 'b', and 'c' are the coefficients of the quadratic equation in the form ax^2 + bx + c = 0.

For the quadratic equation x^2 - 12x + 38 = 0, the coefficients are: a = 1, b = -12, and c = 38. Calculating the discriminant, we have:

Discriminant = (-12)^2 - 4(1)(38) = 144 - 152 = -8

Since the discriminant is -8, it is not equal to 0.

However, for the quadratic equation x^2 - 4x + 4 = 0, the coefficients are: a = 1, b = -4, and c = 4. Calculating the discriminant, we have:

Discriminant = (-4)^2 - 4(1)(4) = 16 - 16 = 0

Since the discriminant is 0, this is the quadratic equation with a discriminant of 0.

The smaller tables can fit 2 people, the larger tables can seat 4 people.

Equation that describes the relationship between the quantity of small tables and the quantity of large tables, assuming exactly 110 people need seats.

Number of people×quantity (small table) + number of people×quantity (large table) = 110

Answer:

The given coordinate pairs are (7,-5), (-5, 4), (-8, 0), and (4, -9). We can use the distance formula to find the length of each side of the quadrilateral formed by these points.

The distance between (7,-5) and (-5, 4) is sqrt((7 - (-5))^2 + ((-5) - 4)^2) = sqrt(12^2 + (-9)^2) = 15.

The distance between (-5, 4) and (-8, 0) is sqrt((-5 - (-8))^2 + (4 - 0)^2) = sqrt(3^2 + 4^2) = 5.

The distance between (-8, 0) and (4, -9) is sqrt((-8 - 4)^2 + (0 - (-9))^2) = sqrt((-12)^2 + 9^2) = 15.

The distance between (4, -9) and (7,-5) is sqrt((4 - 7)^2 + ((-9) - (-5))^2) = sqrt((-3)^2 + (-4)^2) = 5.

So the perimeter of the quadrilateral is 15 + 5 + 15 + 5 = 40.

To find the area of the quadrilateral, we can divide it into two triangles by drawing a diagonal. Let’s use the diagonal between points (7,-5) and (-8,0). The length of this diagonal is sqrt((7 - (-8))^2 + ((-5) - 0)^2) = sqrt(15^2 + (-5)^2) = sqrt(225 + 25) = sqrt(250).

Now we can use Heron’s formula to find the area of each triangle. Let’s start with the triangle formed by points (7,-5), (-8,0), and (-5,4).

The semi-perimeter of this triangle is (15 + sqrt(250) + 5)/2. Let’s call this value s.

Using Heron’s formula, the area of this triangle is sqrt(s * (s - 15) * (s - sqrt(250)) * (s - 5)).

Now let’s find the area of the other triangle formed by points (7,-5), (-8,0), and (4,-9).

The semi-perimeter of this triangle is also (15 + sqrt(250) + 5)/2, which we have already called s.

Using Heron’s formula again, the area of this triangle is also sqrt(s * (s - 15) * (s - sqrt(250)) * (s - 5)).

So the total area of the quadrilateral is 2 * sqrt(s * (s - 15) * (s - sqrt(250)) * (s - 5)).

Answer:

12

Step-by-step explanation:

f(x)=16x-30

g(x)=14x-6

f(x) - g(x) = 16x-30 - (14x-6)

               = 16x - 30 - 14x +6

                = 2x -24

Set this equal to zero

2x-24 = 0

Add 24 to each side

2x-24 +24 = 0+24

2x = 24

Divide by 2

2x/2 =24/2

x = 12

x=12

Answer:

Solution given:

f(x)=16x-30 and g(x)=14x-6

(f-g)(x)=0

Answer:

Step-by-step explanation:

The key here is the "discriminant."  That's b^2 - 4ac, where a, b and c are the coefficients of the quadratic.

If the discriminant turns out to be positive, we have two real, different roots.

If the discriminant turns out to be zero, we have two real, equal roots.

Finally, if the discriminant turns out to be negative, we have two complex, different roots.  

Just supposing that a = 1 and b = 2, the discriminant would be

2^2 - 4(1)c.  Set this equal to 0 and solve for c:  4 - 4c = 0, or c = 1.  If c is greater than 1, the discriminant will be negative and we will have two comlex, different roots.

Answer:

270

Step-by-step explanation:

The formula for finding the area of a triangle is base · height ÷ 2, or \(\frac{bh}{2}\)

After plugging in the numbers given to the formula, we find that the area of the triangle is 27.

Then to account for the length, we multiply the area of the triangle by 10.

This gets us to 270.

(a) The number of pathways in the plane from point (0, 0) to point (110, 111) when each step consists of walking one unit up or one unit to the right is known as the number of ways to go to a point in a grid using just right and up moves.

This is a classic combinatorial problem known as a binomial coefficient. The binomial coefficient C(110+111, 110) = C(221, 110) = 221!/(110!111!) is the number of ways to travel from (0, 0) to (110, 111).

(b) The number of paths from (0, 0) to (210, 111) where each step consists of walking one unit up or one unit to the right and the path must pass through (110, 111) is the product of two binomial coefficients.

First, as calculated in section 1, the number of pathways from (0, 0) to (110, 111) is C(110+111, 110) = C(221, 110). Second, there are C(210+211, 210) ways to get from (110, 111) to (210, 111).

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The functions are given below.

g(n) = n² + 4n

h(n) = - 3n - 3

The function (g+h)(n) is calculated as,

(g+h)(n) = g(n) + h(n)

(g+h)(n) = n² + 4n - 3n - 3

(g+h)(n) = n² + n - 3

Put n = n - 4, then we have
