The values of the missing angles and sides after dilation are:

m∠C'B'D' = 95°,  CQ = 6 and  B'D' = 11.

m∠C'B'D = 180° - m∠B'C'D' - m∠B'D'C'

m∠B'C'D = m∠BCD, m∠B'D'C' = m∠BDC  (dilation)

m∠C'B'D = 180° - 34° - 51° = 95°

Thus, by way of scale factor we can say that:

BC/B'C' = BD/B'D' = 36/18 = 2

B'D' = ¹/₂BD = ¹/₂ * 22 = 11

ΔC'P'Q ∼ ΔCPQ

Thus:

C'Q'/CQ = C'D'/CD = D'Q'/DQ

CQ = 2C'Q' = 2 * 3 = 6

Therefore, m∠C'B'D' = 95°,  CQ = 6 and  B'D' = 11.

Step-by-step explanation:

The equation of the line that is perpendicular to line m and passes through the point (3, 2) is y = (2/5)x + 4/5.

To find the equation of a line that is perpendicular to line m, we need to know the slope of line m.

The slope of line m can be found using the two given points on the line, (0, -3) and (-2, 2):

slope of line m = (change in y) / (change in x) = (2 - (-3)) / (-2 - 0) = 5 / (-2) = -5/2

A line perpendicular to m will have a slope that is the negative reciprocal of -5/2. The negative reciprocal is obtained by flipping the fraction and changing its sign.

slope of line perpendicular to m = -1 / (-5/2) = 2/5

Now we have the slope of the line perpendicular to m and a point that it passes through, (3, 2). We can use the point-slope form of the equation of a line to find its equation:

y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope.

Substituting in the values we have:

y - 2 = (2/5)(x - 3)

Simplifying:

y - 2 = (2/5)x - (6/5)

y = (2/5)x - (6/5) + 2

y = (2/5)x + 4/5

The dilation is centered at the origin and has a scale factor of 0.5.

Here are the steps to find the image coordinates using a dilation centered at the origin with a scale factor of 0.5:

Write down the coordinates of the pre-image points.

P(-4, 2), L(2, 4), A(2, -4), Y(-4, -2)

Multiply each coordinate by the scale factor of 0.5.

P' = (0.5 × -4, 0.5 × 2) = (-2, 1)

L' = (0.5 × 2, 0.5 × 4) = (1, 2)

A' = (0.5 × 2, 0.5 × -4) = (1, -2)

Y' = (0.5 × -4, 0.5 × -2) = (-2, -1)

Write down the image coordinates.

P'(-2, 1), L'(1, 2), A'(1, -2), Y'(-2, -1)

Therefore, the dilation centered at the origin with a scale factor of 0.5 maps the points P(-4, 2), L(2, 4), A(2, -4), Y(-4, -2) to their respective images P'(-2, 1), L'(1, 2), A'(1, -2), Y'(-2, -1).

Answer:

Step-by-step explanation:

Given the inequality  4x - 2y < 22, to get the ordered pair of the inequality, we will have to set x = 0 and y = 0 and then solve for the corresponding inequalities as shown;

when x = 0;

4(0)-2y < 22

-2y < 22

Divide both sides by -2

-2y/-2 > 22/-2

y > -11

When y = 0

4x - 2(0)<22

4x < 22

x < 22/4

x < 11/2

Hence the ordered pair for the inequality expression are y > -11 and x< 11/2

Answer:

Route A is 0.75 km longer than route B.

Step-by-step explanation:

Length of route A is 1.5 times the length of route B.

a = 1.5b

\(\frac{a}{b}=\frac{15}{10}\)

\(\frac{a}{b}=\frac{3}{2}\) --------(1)

Here, a = Length of route A

b = Length of route B

Length of route A is \(\frac{3}{4}\) of route C.

a = \(\frac{3}{4}c\)

\(\frac{a}{c}=\frac{3}{4}\) ------(2)

Here, c = Length of route C

Length of route C = 3 km

Length of route A = \(\frac{3}{4}\times 3\) [From equation (2)]

                             = 2.25 km

Length of route B = \(\frac{2}{3}\times 2.25\) [From equation (1)]

                             = 1.5 km

Difference in route A and route B = 2.25 - 1.5

                                                       = 0.75 km

Therefore, route A is 0.75 km longer than route B.

The correct answer is

\(\[\boxed{\begin{array}{l}G = \left[ {\begin{array}{*{20}{c}}1&0&0&0&1&1\\0&1&0&1&0&1\end{array}} \right]\end{array}}\].\)

The wrong answer on Chegg for the generator matrix is due to swapped values.

Given that the convolutional code is (2, 1, 2) with:

\(\[\begin{array}{l}g^{(1)} = \left( {\begin{array}{*{20}{l}}0&1&1\end{array}} \right)\\g^{(2)} = \left( {\begin{array}{*{20}{l}}1&0&1\end{array}} \right)\end{array}\]\)

Here we can see that there are two generator matrices, which are given as

:g1 = [0 1 1]g2 = [1 0 1]

We have to find the generator matrix (G) for the above convolutional code (2, 1, 2).

Formula to calculate generator matrix G for convolutional code is:

G = [I_k | T] , where T = [g1, g2 g1 + g2].

Here k is the number of states in the convolutional encoder, which is equal to 2 in this case.

Since we have g1 and g2, we can find T as follows:

\(\[T = \left[ {\begin{array}{*{20}{c}}0&1&1&1&0&1\end{array}} \right]\]where g1 + g2 is equal to [1 1 0].\)

Since we have the matrix T, we can now calculate G as follows:

\(\[G = \left[ {\begin{array}{*{20}{c}}1&0&0&0&1&1\\0&1&0&1&0&1\end{array}} \right]\]\)

Thus, the generator matrix G for the convolutional code (2, 1, 2) is:

\(\[G = \left[ {\begin{array}{*{20}{c}}1&0&0&0&1&1\\0&1&0&1&0&1\end{array}} \right]\]\)

Therefore, the correct answer is

\(\[\boxed{\begin{array}{l}G = \left[ {\begin{array}{*{20}{c}}1&0&0&0&1&1\\0&1&0&1&0&1\end{array}} \right]\end{array}}\].\)

Step-by-step explanation:

The road would need to be plowed 7 times for there to be less than 1/2 inch of snow left on it. After each plowing, the amount of snow left on the road reduces progressively.

The snowplow removes three fourths of the snow on the road each time it goes down. Starting with 24 inches of snow, we can calculate the amount of snow left after each plowing.

After the first plowing, three-fourths of 24 inches of snow is removed, leaving 24 * (1 - 3/4) = 6 inches of snow on the road. After the second plowing, three-fourths of the remaining 6 inches of snow is removed, leaving 6 * (1 - 3/4) = 1.5 inches of snow on the road. After the third plowing, three-fourths of the remaining 1.5 inches of snow is removed, leaving 1.5 * (1 - 3/4) = 0.375 inches of snow on the road.

This process continues for each subsequent plowing. After the seventh plowing, the amount of snow left on the road would be less than 1/2 inch, which is the desired condition.

The experimental probability of selecting a red marble is 12/20, which simplifies to 3/5 or 0.6 as a decimal.

The theoretical probability of selecting a red marble can be calculated by dividing the number of red marbles by the total number of marbles:

P(red) = number of red marbles / total number of marbles

In this case, there are 27 red marbles out of 70 total marbles:

P(red) = 27/70

Therefore, the theoretical probability of selecting a red marble is 27/70, which cannot be simplified further as a fraction. As a decimal, it is approximately 0.386.

The mean of X is 365, the variance is 364, and the standard deviation is approximately 19.1.

(a) The probability mass function (pmf) of X, which represents the number of people needed to find someone with the same birthday as yours, follows a geometric distribution.

The pmf is given by P(X=k) = (365/365) * (364/365)   (365-k+1)/365 for k = 1, 2, 3, where the fractions represent the probability of not finding a matching birthday in the first k-1 individuals and the probability of finding a matching birthday with the kth individual.

(b) The mean of X is E(X) = 365, the variance is Var(X) = 365, and the standard deviation is SD(X) = √365.

(a) The pmf of X follows a geometric distribution because we are interested in the number of trials (people asked) needed to achieve the first success (finding someone with the same birthday as yours).

The probability of not finding a matching birthday with each individual is (365-1)/365 = 364/365, as there are 364 days other than your birthday. Therefore, the pmf is given by P(X=k) = (365/365) * (364/365) * ... * (365-k+1)/365 for k = 1, 2, 3, ....

(b) The mean of a geometric distribution is given by E(X) = 1/p, where p is the probability of success. In this case, p = 1/365, so E(X) = 1 / (1/365) = 365.

The variance of a geometric distribution is Var(X) = (1-p) / p^2, which simplifies to Var(X) = (364/365) / (1/365)^2 = 364. The standard deviation is the square root of the variance, so SD(X) = √364 ≈ 19.1.

Hence, the mean of X is 365, the variance is 364, and the standard deviation is approximately 19.1.

Measure of angle E, m ∠E = 46°

Measure of angle D, m ∠D = 46°

The correct option is the third option m∠E = 46°, m∠D = 46°

From the question, we are to determine the measure of each angle.

From the given information,

The measure of ∠E, the angle of elevation from point A to point B, is (3x + 1).

The measure of ∠D, the angle of depression from point B to point A, is 2(x+8).

This means

The measure of ∠E = The measure of ∠D

(3x + 1)° = 2(x + 8)°

Solve for x

3x + 1 = 2(x + 8)

3x + 1 = 2x + 16

3x - 2x = 16 - 1

x = 15

Measure of ∠E = (3x + 1)°

Measure of ∠E = (3(15) + 1)°

Measure of ∠E = (45 + 1)°

Measure of ∠E = 46°
