Answer:

0

Step-by-step explanation:

Assuming there is no typo in your question, the slope is 0 because the function is a horizontal line.

To determine the 95% energy bandwidth (B) of the signal g(t) = [0.5sinc²(0.5 t) cos(2 t)], we can apply Parseval's Theorem. Parseval's Theorem states that the total energy of a signal in the time domain is equal to the total energy of the signal in the frequency domain. Mathematically, it can be expressed as:

∫ |g(t)|² dt = ∫ |G(f)|² df

In this case, we want to find the frequency range within which 95% of the energy of the signal is concentrated. So we can rewrite the equation as: 0.95 * ∫ |g(t)|² dt = ∫ |G(f)|² df

Now, we need to evaluate the integral on both sides of the equation. Since the given signal is in the form of a product of two functions, we can separate the terms and evaluate them individually. By applying the Fourier transform properties and integrating, we can find the value of B.

For part (b), when we consider g(2t), the time domain signal is compressed by a factor of 2. This compression results in a corresponding expansion in the frequency domain. Therefore, the 95% energy bandwidth of g(2t) will be twice the value of B determined in part (a). This can be justified by considering the relationship between time and frequency domains in Fourier analysis, where time compression corresponds to frequency expansion and vice versa.

The first two numbers in each row of the relative frequency table represent the percentage of cars and trucks of a particular color out of the total number of vehicles in the parking lot.

To create a relative frequency table, we need to divide the frequency of each color by the total number of vehicles (65) and then multiply by 100 to get a percentage.

Relative Frequency Table by Color:

The first two numbers in each row must add up to 100% because we are calculating the relative frequency of each color with respect to the total number of vehicles (65). Therefore, the percentage of cars and trucks of each color must add up to 100% of that color's total frequency. The total row must also add up to 100% because it represents the entire population of vehicles.

The mathematical expression with unequal sides is known as an inequality in mathematics. Inequality is referred to in mathematics when a relationship results in a non-equal comparison between two expressions or two numbers. In this instance, any of the inequality symbols, such as greater than symbol (>), less than symbol (), greater than or equal to symbol (), less than or equal to symbol (), or not equal to symbol (), is used in place of the equal sign "=" in the expression. Polynomial inequality, rational inequality, and absolute value inequality are the various types of inequalities that can exist in mathematics. A linear inequality looks precisely like a linear equation, but the symbol connecting two expressions is different.

Let x represent the number of roast beef dinners and y represent the number of teriyaki chicken dinners.

The total cost of the roast beef dinners is 5x dollars and the total cost of the teriyaki chicken dinners is 3y dollars.

Therefore, the total cost of all the dinners is 5x + 3y dollars.

We know that the total cost of all the dinners must be less than or equal to $1200, so we can write the inequality:

5x + 3y <= 1200

We also know that we must serve at least 240 customers, which means that we must serve at least 240 dinners. Since we are serving two different meals, this means that we must serve at least 120 of each meal. Therefore, we can write the following system of inequalities:

Answer:

x = 84°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

129° is an exterior angle of the triangle, thus

x + 45° = 129° ( subtract 45° from both sides )

x = 84°

The 2 triangles formed by the tree/ shadow and Jordan/ shadow are similar and ratio of corresponding sides are equal, that is

let h be the height of the tree, then

\(\frac{h}{7}\) = \(\frac{50}{10}\) = 5 ( multiply both sides by 7 )

h = 35

The height of the tree is 35 ft

The opposite side of the right triangle (x) is approximately 6.888 inches long.

To solve this problem, we can use the trigonometric ratio for the sine function, which is opposite/hypotenuse. We have the hypotenuse as 12 inches and the opposite angle as 35 degrees, so we can set up the equation:

sin(35) = opposite/12

To solve for the opposite, we can multiply both sides by 12:

opposite = 12 * sin(35)

sin(35) as approximately 0.574:

opposite = 12 * 0.574

opposite ≈ 6.888

Therefore, the opposite side of the right triangle (x) is approximately 6.888 inches long.

A triangle has sides with lengths of 6 kilometers, 7 kilometers, and 10 kilometers is not a right triangle.

To determine if a triangle is a right triangle, you can use the Pythagorean Theorem. The Pythagorean Theorem states that "In a right-angled triangle, the sum of the square of the two shorter sides is equal to the square of the longest side." It can be written as:

a² + b² = c², where 'a' and 'b' are the lengths of the two legs of a right triangle, and 'c' is the length of the hypotenuse.

In this triangle, the two shorter sides have lengths of 6 kilometers and 7 kilometers and the longest side is 10 kilometers.

The square of 6 kilometers is 36 kilometers and the square of 7 kilometers is 49 kilometers.

The sum of 36 kilometers and 49 kilometers is 85 kilometers.

The longest side of the triangle has a length of 10 kilometers, and the square of 10 kilometers is 100 kilometers.

Since 85 kilometers is not equal to 100 kilometers, this triangle is not a right triangle.

We need to utilize the concept of the z-score and the properties of the normal distribution. Given that the distribution is normal and the population variance is known, we can calculate the z-score, proportions, margin of error, and confidence interval.

a. To calculate the z-value for a person who spends 74 euros, we use the formula:    z = (x - μ) / σ    where x is the value, μ is the mean, and σ is the standard deviation.   z = (74 - 80) / √6 ≈ -2.45    The z-value of -2.45 indicates that the person's spending of 74 euros is approximately 2.45 standard deviations below the mean. It suggests that the person's spending is relatively low compared to the average.

b. To calculate the z-value for a person who spends 84 euros, we use the same formula:

  z = (84 - 80) / √6 ≈ 1.63

  The z-value of 1.63 indicates that the person's spending of 84 euros is approximately 1.63 standard deviations above the mean. It suggests that the person's spending is relatively high compared to the average.

c. To find the proportion of people who spend no more than 74 euros, we calculate the cumulative probability using the z-score:

  P(X ≤ 74) = P(Z ≤ -2.45)

  Using a standard normal distribution table or calculator, we find that P(Z ≤ -2.45) ≈ 0.0071

  Therefore, approximately 0.71% of people spend no more than 74 euros for online shopping.

d. To find the proportion of people who spend more than 84 euros, we calculate the complementary probability:

  P(X > 84) = 1 - P(X ≤ 84) = 1 - P(Z ≤ 1.63)

  Using a standard normal distribution table or calculator, we find that P(Z ≤ 1.63) ≈ 0.9474

  Therefore, approximately 5.26% of people spend more than 84 euros for online shopping.

e. To find the proportion of people who spend between 74 and 84 euros, we calculate the difference between cumulative probabilities:

  P(74 < X < 84) = P(X ≤ 84) - P(X ≤ 74)

  P(74 < X < 84) = P(Z ≤ 1.63) - P(Z ≤ -2.45)

  Using a standard normal distribution table or calculator, we find that P(Z ≤ 1.63) ≈ 0.9474 and P(Z ≤ -2.45) ≈ 0.0071

  P(74 < X < 84) ≈ 0.9474 - 0.0071 ≈ 0.9403

  Therefore, approximately 94.03% of people spend between 74 and 84 euros for online shopping.

f. The obtained result in question e means that approximately 94.03% of people fall within the range of 74 to 84 euros for online shopping.

g. To find the margin of error at a 5% significance level, we use the formula:

  Margin of Error = z * (σ / √n)

  Since the sample size is not provided, we assume it to be the same as the number of analyzed people, which is 50.

Answer:

3.5 : 7 > 1.2 : 2.5.

Step-by-step explanation:

1. Compare the ratios 4 : 5 and 2 : 3.

Solution:

Express the given ratios as fraction

4 : 5 = 4/5 and 2 : 3 =2/3

Now find the L.C.M (least common multiple) of 5 and 3

The L.C.M (least common multiple) of 5 and 3 is 15.

Making the denominator of each fraction equal to 15, we have

4/5 = (4 ×3)/(5 ×3) = 12/15 and 2/3 = (2 ×5)/(3 ×5) = 10/15

Clearly, 12 > 10

Now, 12/15 > 10/15

Therefore, 4 : 5 > 2 : 3.

2. Compare the ratios 5 : 6 and 7 : 9.

Solution:

Express the given ratios as fraction

5 : 6 = 5/6 and 7 : 9 =7/9

Now find the L.C.M (least common multiple) of 6 and 9

The L.C.M (least common multiple) of 6 and 9 is 18.

Making the denominator of each fraction equal to 18, we have

5/6 = (5 ×3)/(6 ×3) = 15/18 and 7/9 = (7 ×2)/(9 ×2) = 14/18

Clearly, 15 > 14

Now, 15/18 > 14/18

Therefore, 5 : 6 > 7 : 9.

3. Compare the ratios 1.2 : 2.5 and 3.5 : 7.

Solution:

1.2 : 2.5 = 1.2/2.5 and 3.5 : 7 =3.5/7

1.2/2.5 = (1.2 ×10)/(2.5 ×10 ) = 12/25 and 3.5/7 = (3.5 ×10)/(7 ×10) = 35/70 = 1/2

[We removed the decimal point from the ratios now, we will compare the ratio]

Now find the L.C.M (least common multiple) of 25 and 2

The L.C.M (least common multiple) of 25 and 2 is 50.

Making the denominator of each fraction equal to 50, we have

= 12/25 = (12 ×2)/(25 ×2) = 24/50 and 1/2 = (1 ×25)/(2 ×25) = 25/50

Now, 25/50 > 24/50

Therefore, 3.5 : 7 > 1.2 : 2.5.
