Zero is always greater than any negative integer.

The standard form of the equation of the hyperbola with foci at (±5, 0) and asymptotes y = ±4/3x is (x^2 / 9) - (y^2 / 16) = 1.

To find the standard form of the equation of a hyperbola, we need to determine the distances and slopes associated with its foci and asymptotes.

The foci of the hyperbola are given as (±5, 0). The distance between the center (origin) and each focus is denoted by c. In this case, c = 5.

The asymptotes of the hyperbola are represented by the equations y = ±(a / b)x, where a and b are the lengths of the transverse and conjugate axes, respectively. The slopes of the asymptotes are given as ±4/3.

From the given information, we can determine the values of a and b. The distance between the center and each vertex is a, and since the transverse axis is horizontal, a = 5.

Using the relationship a^2 + b^2 = c^2, we can find b: (5^2) + b^2 = (5^2) + (4/3)^2. Solving this equation gives b = 4.

Finally, we can write the standard form of the equation of the hyperbola as (x^2 / a^2) - (y^2 / b^2) = 1. Substituting the values of a and b, we obtain (x^2 / 9) - (y^2 / 16) = 1.

Therefore, the standard form of the equation of the hyperbola is (x^2 / 9) - (y^2 / 16) = 1.

To write the constructor for the Digits class, follow these steps:

1. Create the class Digits and initialize an empty list named digitlist inside the class.
2. Define the constructor using the __init__ method, which takes the non-negative integer 'num' as a parameter.
3. Inside the constructor, convert the integer 'num' into a string to process each digit individually.
4. Iterate through each character in the string and convert it back to an integer, then append it to the digitlist.
5. Make sure that the elements in digitlist are Integer objects representing single digits and appear in the same order as the digits in 'num'.

Here's the code for the Digits class constructor:

Now, when you create a Digits object and pass a non-negative integer to the constructor, it initializes and fills the digitlist with the digits from that integer. The elements in digitlist will be Integer objects representing single digits, and they will appear in the same order as the digits in the given integer.

The decimal system value of the binary floating point representation [1, 1, 1, 0, 1, 1, 0, 1] with three bits used to represent the magnitude of the characteristic is -13.

To determine the decimal value of the given binary representation, we need to separate it into its three components: sign, characteristic, and mantissa.

The sign bit is the leftmost bit, which is 1, indicating a negative value.

The characteristic is the next three bits, which are [1, 1, 1]. To determine the decimal value of the characteristic, we convert it from binary to decimal. In this case, [1, 1, 1] in binary is equal to 7 in decimal.

The mantissa is the remaining bits, which are [0, 1, 1, 0, 1]. To determine the decimal value of the mantissa, we convert it from binary to decimal. In this case, [0, 1, 1, 0, 1] in binary is equal to 0.375 in decimal.

The decimal system value, v, can be calculated using the formula: v = (-1)^sign * (1 + mantissa) * 2^(characteristic - bias), where the bias is 2^(n-1) - 1, and n is the number of bits used to represent the characteristic.

In this case, the bias is 2^(3-1) - 1 = 3, and the values we have are:

sign = 1 (negative)

characteristic = 7

mantissa = 0.375

Plugging these values into the formula, we get:

v = (-1)^1 * (1 + 0.375) * 2^(7 - 3)

 = (-1) * 1.375 * 2^4

 = -1.375 * 16

 = -22

The decimal system value of the binary floating point representation [1, 1, 1, 0, 1, 1, 0, 1], with three bits used to represent the magnitude of the characteristic, is -13.

Step-by-step explanation:

The probability that a randomly selected user is online less than 15 hours a week is 0.1056 (approx).

As per the given statement, u.s. internet users spend an average of 18.3 hours a week online. If 95% of users spend between 13.1 and 23.5 hours a week, we need to determine the probability that a randomly selected user is online less than 15 hours a week.

To find the probability that a randomly selected user is online less than 15 hours a week, we need to use the Z-score formula, which is defined as:

Z = (X - μ) / σ

Where Z is the z-score, X is the value of the element, μ is the mean of the population, and σ is the standard deviation. Therefore, the probability of a randomly selected user being online less than 15 hours per week can be calculated as follows:Z = (15 - 18.3) / σ

We know that 95% of users spend between 13.1 and 23.5 hours per week, which means that the standard deviation is given by:

13.1 - 18.3 = 5.4 hours (lower bound)

23.5 - 18.3 = 5.2 hours (upper bound)

Therefore, σ = (5.4 + 5.2) / 4 = 2.65 hours

Hence, the z-score can be calculated as follows:Z = (15 - 18.3) / 2.65 = -1.25

Thus, the probability that a randomly selected user is online less than 15 hours a week is P(Z < -1.25). Using a standard normal distribution table, we can find that P(Z < -1.25) = 0.1056 (approx).

The hiker's resultant displacement can be calculated using vector addition. By considering the magnitudes and directions of the individual displacements, the resultant displacement can be determined.

The magnitude of the resultant displacement is approximately 3.8 km, rounded to the nearest tenth. The direction of the resultant displacement is approximately 7° south of west, rounded to the nearest whole degree.

To find the resultant displacement, we can break down the hiker's displacements into their respective components. The first displacement of 3.5 km at an angle of 55° south of west can be represented as -3.5 km westward and -3.5 km × sin(55°) = -2.9 km southward. The second displacement of 2.7 km at an angle of 16° east of south can be represented as +2.7 km southward and +2.7 km × sin(16°) = +0.7 km eastward.

To find the resultant displacement, we add the components in each direction separately. The westward components add up to -3.5 km, and the southward components add up to -2.9 km + 2.7 km = -0.2 km. Using the Pythagorean theorem, the magnitude of the resultant displacement is √((-3.5 km)² + (-0.2 km)²) ≈ 3.8 km (rounded to the nearest tenth).

To determine the direction of the resultant displacement, we can use trigonometry. The angle θ can be calculated as arctan((-0.2 km)/(-3.5 km)) ≈ 7°. Since the angle is measured south of west, the direction of the resultant displacement is approximately 7° south of west (rounded to the nearest whole degree).

The Domain of a function is the set of all possible input values (values of x) for which the function is defined and produces a valid output (value of y).

For the function g(x) = (x² - 3x - 18)/(x² − 4), the only restriction on the domain is the denominator (x² − 4) cannot be equal to 0. This is because division by zero is undefined.

So, the domain of the function g(x) is all real numbers except x = ±2, because if we substitute x = 2 or -2 , the denominator becomes 0 and hence undefined .

Bacterial cell is smaller than the amoeba cell by 70 times or 7^ 10 times

What is mathematical expression?

A mathematical expression is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

length of a bacterial cell = 5 x 10^-6 m

length of an amoeba cell = 3.5 x 10^-4 m

= 3.5 x 10^-4 x 100/100 m

= 350 x 10^-6 m

Now, comparing the length

= (350 x 10∧-6) / (5 x 10∧-6 )

= (350/5

= 70 times or 7^ 10 times

Based on the given information, the net amount your firm will receive on the next transaction date can be calculated by subtracting the variable interest rate from the fixed interest rate.

In the swap agreement, your firm pays a fixed interest rate of 5.50 percent and receives a variable interest rate equal to LIBOR (London Interbank Offered Rate) plus 150 basis points. LIBOR is currently 3.75 percent.

To calculate the net amount your firm will receive on the next transaction date, we need to subtract the variable interest rate from the fixed interest rate.

Fixed interest rate: 5.50%

Variable interest rate: LIBOR (3.75%) + 150 basis points (1.50%) = 5.25%

Therefore, the net amount your firm will receive on the next transaction date is the difference between the fixed interest rate and the variable interest rate, which is 0.25%.

Part 1: Kate should buy 100 coats to maximize profits.Part 2: The probability that the coats sell out is 0.25 (25%), and the probability that they do not sell out is 0.75 (75%).

To maximize profits, Kate should consider the scenario where she sells all the coats without any left over at the end of the season.

Since the sales are uniformly distributed between 100 and 400, buying 100 coats ensures that she meets the minimum expected sales of 100. Purchasing more than 100 coats would increase costs without a guarantee of higher sales, potentially leading to excess inventory and lower profits.

Given that the sales are uniformly distributed between 100 and 400 coats, Kate's purchase of 100 coats covers the minimum expected sales.

The probability of selling out can be calculated by finding the proportion of the range covered by the desired sales (100 out of 300). Therefore, the probability of selling out is 100/300 = 0.25 or 25%. The probability of not selling out is the complement, which is 1 - 0.25 = 0.75 or 75%.

a) Since the triangles are congruent, and ΔABC is congruent to ΔDEF, segments AB and DE have the same value. Therefore, you can use algebra to solve for x when using the knowledge that (12 - 4x) is equal to (15 - 3x).

To solve:

12 - 4x = 15 - 3x

12 = 15 + x

-3 = x

Therefore, x is equal to -3.

b) To find the value of AB, plug in the value of x found in part a).

12 - 4x

12 - 4(-3)

12 - (-12)

12 + 12 = 24

Thus, segment AB is equal to 24.

c) As shown in part b), plug in the value of x found in part a) to find the value of segment DE.

15 - 3x

15 - 3(-3)

15 - (-9)

15 + 9 = 24

Thus, segment DE is also equal to 24.

We can confirm the knowledge of the equal side lengths because the triangle are congruent. This means that all the side lengths in the triangle are the same, which is confirmed when algebraically plugging in the value of x to solve for the values of the segments AB and DE.
