What is the binary number for 14​

Answer:

x = 5°

EF = 58°

GH = 55°

Step-by-step explanation:

From The diagram :

Recall ; Angle on a straight line = 180°

This means :

EF + FG + GH = 180

EF = (10x + 8)°

GH = (11x)°

FG = 67°

HENCE;

10x + 8 + 11x + 67 = 180

21x + 75° = 180°

21x = 180 - 75

21x = 105

x = 105 / 21

x = 5

EF = 10x + 8 = 50 + 8 = 58°

GH = 11x = 11 * 5 = 55°

If we know the DFT value for a certain index k (0 < k < M-1) of a real sequence x[n], we can determine the DFT value for another index k2 (0 < k2 < M-1) if k2 is related to k through complex conjugation. In other words, if k2 is the conjugate of k, then we can determine the DFT value for k2.

For a real sequence, the DFT values follow a symmetry property. If X[k] is the DFT value at index k, then X[M - k] is the DFT value at index k2, where k2 = M - k. The value of the DFT for k2 would be the complex conjugate of the DFT value for k, denoted as X[M - k] = X[k]*. The asterisk (*) represents complex conjugation.

In summary, if we know the DFT value for a certain index k in a real sequence, we can determine the DFT value for the index k2 = M - k, and the value of the DFT for k2 would be the complex conjugate of the DFT value for k.

If M is a minimal DFA accepting L, then the DFA Mˉ accepting the complement of L is also minimal.

(a) To prove that the class of regular languages is closed under complement, we need to show that for any regular language L, its complement Lˉ is also a regular language.

Let's assume that L is a regular language. This means that there exists a DFA (Deterministic Finite Automaton) M that accepts L. We need to construct a DFA M' that accepts the complement of L, Lˉ.

To construct M', we can simply swap the accepting and non-accepting states of M. In other words, for every state q in M, if q is an accepting state in M, then it will be a non-accepting state in M', and vice versa. The transition function and start state remain the same.

The intuition behind this construction is that M accepts strings that are in L, and M' will accept strings that are not in L. By swapping the accepting and non-accepting states, M' will accept the complement of L.

Since we can construct a DFA M' that accepts Lˉ from the DFA M that accepts L, we have shown that Lˉ is a regular language. Therefore, the class of regular languages is closed under complement.

(b) Now, let's assume that M is a minimal DFA that accepts the language L. We need to prove that Mˉ, the DFA accepting the complement of L, is also minimal.

To prove this, we can use a contradiction argument. Let's assume that Mˉ is not minimal, i.e., there exists a DFA M'' that accepts Lˉ and has fewer states than M. Our goal is to show that this assumption leads to a contradiction.

Since M is minimal, it means that there is no DFA M' that accepts L and has fewer states than M. However, we have assumed the existence of M'', which accepts Lˉ and has fewer states than M.

Now, consider the DFA M''', obtained by swapping the accepting and non-accepting states of M''. In other words, for every state q in M'', if q is an accepting state in M'', then it will be a non-accepting state in M''', and vice versa. The transition function and start state remain the same.

We can observe that M''' accepts L because it accepts the complement of Lˉ, which is L. Moreover, M''' has fewer states than M, which contradicts the assumption that M is minimal.

Therefore, our initial assumption that Mˉ is not minimal leads to a contradiction. Hence, if M is minimal, then Mˉ is also minimal.

In conclusion, we have proven that if M is a minimal DFA accepting L, then the DFA Mˉ accepting the complement of L is also minimal.

When h=9 and j=1/2 the q value is 1152.

Given that:

q is directly proportional to the square root of h and inversely proportional to the cube of​ j, and q=24 when h= 16 and j=2.

q ∝ \(\sqrt{h}\)/\(j^{3}\)

q = k \(\sqrt{h}\)/\(j^{3}\)

24 = k \(\sqrt{16}\)/\(2^{3}\)

24 = k 4/8

k = 24 *2

k = 48

q = 48 \(\sqrt{h}\)/\(j^{3}\)

substitute h = 9 and j = 1/2

q = 48\(\sqrt{9\)/\(1/2^{3}\)

q = 48 * 3/1/8

q = 48 * 3 * 8

q = 48 * 24

q = 1152

Therefore when h=9 and j=1/2 the q value is 1152.

To solve a proportion like x/a = b/c, you need to find the value of x that makes the two ratios equal. You can do this by cross-multiplying, which involves multiplying the numerator of one ratio by the denominator of the other ratio, and vice versa. We start by multiplying both sides by ac, giving us x = (ab)/c.

In summary, to solve a proportion of this form in just three steps, we multiply both sides by the product of the denominators, then simplify the resulting expression to get the value of x. To solve a proportion like x/a = b/c, you need to find the value of x that makes the two ratios equal. You can do this by cross-multiplying, which involves multiplying the numerator of one ratio by the denominator of the other ratio, and vice versa.

Following the cross-multiplying method, you multiply the two numbers that are diagonally opposite each other, then do the same for the remaining two numbers. In this case, multiply 'a' by 'c' and 'x' by 'b'. This results in the equation: x * b = a * c. To find the value of x, divide both sides of the equation by 'b'. This will give you the final equation: x = (a * c) / b. By plugging in the values for a, b, and c, you can easily solve for x and find the value that satisfies the proportion x/a = b/c.

Answer:

\(\boxed {x = 19}\)

Step-by-step explanation:

Solve for the value of \(x\):

\(3x - 4 = 15 + 2x\)

-Take \(2x\) and subtract it from \(3x\):

\(3x - 4 - 2x = 15 + 2x - 2x\)

\(x - 4 = 15\)

-Add \(4\) to both sides:

\(x - 4 + 4 = 15 + 4\)

\(\boxed {x = 19}\)

So, the value of \(x\) is \(19\).

Answer:

x +15 + x -1 =1

x+x +15-1 =1

2x-14=1

2x-14-14=1-14

2x =-13

The simplified expression is (-187.584x + 287.6672) / 6.8, which is equivalent to option A: -2.84x - 1.66.

To simplify the expression 5.3x - 8.14 / 3.6x - 9.8, we can first simplify the division by finding a common denominator for the fractions.

The common denominator for 3.6x and 9.8 is 3.6x * 9.8 = 35.28x.

Next, we can rewrite the expression using the common denominator:
5.3x * (35.28x/35.28x) - 8.14 * (35.28x/35.28x) / 3.6x * (35.28x/35.28x) - 9.8 * (35.28x/35.28x)

Simplifying further, we get:
(5.3 * 35.28x^2 - 8.14 * 35.28x) / (3.6 * 35.28x - 9.8 * 35.28x)

Now, we can simplify the numerator:
(187.584x^2 - 287.6672x) / (-6.8x)

Factoring out an x from the numerator, we have:
x(187.584x - 287.6672) / (-6.8x)

Finally, we can cancel out the x terms:
(187.584x - 287.6672) / -6.8

Therefore, the simplified expression is (-187.584x + 287.6672) / 6.8, which is equivalent to option A: -2.84x - 1.66.

Delaney  solve for X by isolating it,  or getting it by it self

Step-by-step explanation:

5x−2(x+1)=1/4 (distribute the 2)

5x-2x - 2 = 1/4  (subtract 2x from 5x)

3x -2 +2 = 1/4 +2 (add 2 to both sides)

3x = 2_1/4  (put 2 &  1/4 together)

3x = 9/4 (convert 2_1/4 to  9/4)

\(\frac{1}{3}\)*3*x =  \(\frac{1}{3}\)*\(\frac{9}{4}\)  ( mutilply both sides by  1/3)

Inverse variation can be defined as the relationship between two variables, so that if the value of one of the variable increases the value of the other variable decreases.

Example: If a varies inversely as b

This can be represented as;

a ∝ 1/b

Then,

ab = k

Where k is the proportionality constant

From the information given, we have that;

x ∝ 1/ y

Then,

xy = k

Substitute the values

476 (17) = k

k = 8092

If x = 1428 and k = 8092

Let's determine the value of y

y = k/x

y = 8092/1428

y = 5. 67 liters

Where is the Question?

Step-by-step explanation:

the probability that x falls between 65.75 and 68.75 is approximately 0.087 or 8.7%.

To find the probability that x falls between 65.75 and 68.75, we need to calculate the z-scores corresponding to these values and use the standard normal distribution.

The z-score is calculated using the formula:

z = (x - µ) / σ

where x is the value, µ is the population mean, and σ is the population standard deviation.

For 65.75:
z1 = (65.75 - 65) / 12 = 0.0625

For 68.75:
z2 = (68.75 - 65) / 12 = 0.2917

Using a standard normal distribution table or a calculator, we can find the probabilities corresponding to these z-scores.

P(0.0625 < z < 0.2917) = P(z < 0.2917) - P(z < 0.0625)

By looking up the values in the standard normal distribution table, we find that P(z < 0.2917) = 0.6159 and P(z < 0.0625) = 0.5289.

Therefore, P(0.0625 < z < 0.2917) = 0.6159 - 0.5289 = 0.087

Hence, the probability that x falls between 65.75 and 68.75 is approximately 0.087 or 8.7%.

According to the sample data, the best conclusion supported by the sample data is that approximately 30% of all largemouth bass in the pond weigh more than 2 pounds. The answer is (D) Approximately 30% of all largemouth bass in the pond weigh more than 2 pounds.

The conclusion that is best supported by the sample data is that approximately 30% of all largemouth bass in the pond weigh more than 2 pounds, which is based on the fact that the sample contained 150 largemouth bass, of which 30% weighed more than 2 pounds.

Therefore, options A and C are incorrect. The sample data does not provide enough information to determine the average weight of all fish in the pond, so option B is also incorrect.

The correct answer is D) Approximately 30% of all largemouth bass in the pond weigh more than 2 pounds. This conclusion is supported by the sample data because the study specifically included a sample of 150 largemouth basses, of which 30% weighed more than 2 pounds.

In a statistical inference method, you'll draw a conclusion in the end - you'll infer something - about the characteristics of what you're comparing.

Statistical inference is a process used in statistics to draw conclusions or make predictions about a population based on a sample. It involves using data from a sample to make inferences about the larger population from which the sample is drawn.

To perform statistical inference, you typically follow these steps:

1. Formulate a research question or hypothesis: Start by identifying what you want to investigate or test. For example, you might want to determine if there is a significant difference in test scores between students who receive tutoring and those who do not.

2. Collect data: Gather relevant data through surveys, experiments, or other methods. In the example above, you would collect test scores from both the tutoring and non-tutoring groups.

3. Choose an appropriate statistical inference method: There are various statistical inference methods available, such as hypothesis testing, confidence intervals, and regression analysis. Select the method that best suits your research question and data.

4. Analyze the data: Apply the chosen statistical inference method to the collected data. This involves performing calculations and statistical tests to draw conclusions about the population based on the sample.

5. Draw conclusions: Based on the results of the analysis, draw conclusions about the characteristics of the population you are studying. In our example, you might conclude that students who receive tutoring have significantly higher test scores than those who do not.

In summary, in a statistical inference method, you use data from a sample to draw conclusions or make predictions about the characteristics of a larger population. This process involves formulating a research question, collecting data, selecting an appropriate inference method, analyzing the data, and drawing conclusions based on the results.
