what is the rule for finding the sum of two negative integers

The correct option is "O Increase the precision." The statement that is not a reason for having a simple tree structure is to "Increase the precision". A tree structure is a structure in which different nodes are connected in the shape of a tree.

A node that has no parent node is referred to as the root node. The degree of a node is the number of edges connecting it to the children. Every parent node has more than one child node in a tree structure. A decision tree is a tree-shaped graph that is employed to create a model of decisions and their related consequences. The need for a simple tree structure is as follows: Easy to interpret: It is simple to interpret and understand the decision rules in a simple tree structure. Avoid over-fitting: When a decision tree is too complex, it is prone to overfitting.

As a result, a simpler tree structure is required to avoid this. A simpler tree structure aids in preventing overfitting and allowing for more generalized results. Increase the model robustness: A model's performance can be improved by keeping it simple. A simple model is usually more stable and consistent than a complex model that is prone to overfitting. Increase precision is not a reason for having a simple tree structure.

The value of x in the chord intersection is 16 units.

The intersecting chord theorem  states that the products of the lengths of the line segments on each chord are equal. In other words, If two chords intersect in a circle , then the products of the measures of the segments of the chords are equal.

Therefore, lets find the value of x in the intersecting chords as follows:

15 × x = 24 × 10

15x = 240

divide both sides of the equation by 15

x = 240 / 15

x = 16

multiply the length value by 4

Answer:

57.15 cm

Step-by-step explanation:

FORMULA  

multiply the value by 2.54

Hope this helps! have a great day :)

Answer:

57.15 cm

Step-by-step explanation:

Use the appropriate conversion factor:

22.5 in     2.54 cm

----------- * -------------- = 57.15 cm

      1            1 in

So the final expression is: (change in y/y) = n (change in a/a).

We can start by taking the natural logarithm of both sides of the equation:

ln(y) = ln(aⁿ)

Using the rule that ln(aⁿ) = n ln(a), we can simplify this to:

ln(y) = n ln(a)

Next, we can take the derivative of both sides with respect to a:

d/d(a) ln(y) = d/d(a) (n ln(a))

Using the chain rule, we can simplify the right-hand side to:

d/d(a) ln(y) = n (1/a)

Now, we can multiply both sides by a/y:

a/y * d/d(a) y = n(a/y) * (1/a)

Simplifying, we get:

dy/y = n da/a

50% of Susan's trips to class would take more than 50 minutes.Answer: 50%.

Given data: The average time it takes for Susan to get to her class is 50 minutes. And the standard deviation is 5 minutes. We have to find the proportion of Susan's trips to class would take more than 50 minutes.

Solution:To find out the required proportion, we need to calculate the Z-score first.

\(Z-score = (X - μ)/σ\)

where, X = the value of the random variable (Susan's time to get to class)

μ = the population mean (average time)σ = the standard deviation

Here, X = 50 minutes

μ = 50 minutes

σ = 5 minutes

Z-score = (X - μ)/σ

= (50 - 50)/5

= 0

The Z-score table indicates that the area under the standard normal distribution curve for a Z-score of 0 is 0.5. Therefore, 50% of Susan's trips to class would take more than 50 minutes.Answer: 50%.

Answer:

A spring stretches 2.5 inches for each ounce of weight. Use this information for problems 9-11. 9. Determine a function that represents this situation.

Step-by-step explanation:

Answer: y = 17x + 114

Step-by-step explanation:

The equation for the slope-intercept form is y = mx + b.

Arrange the equation so that it resembles y = mx + b.

You will do this by multiplying and subtracting so y is on the left side of the equation and mx + b is on the right side of the equation.

y + 5 = 17(x + 7)

y + 5 = 17x + 119

y + 5 - 5 = 17x + 119 - 5

y = 17x + 114

Answer:

Y = 17x + 114

Step-by-step explanation:

1. Y + 5 = 17 (x+7)

2. Y + 5 = 17x + 119   [Multiply the numbers in parenthesis by 17.]

3. Y = 17x + 114.     [To keep the balance and move the 5 over, subtract it from 119.]

(Original price) - 0.30p = 84

Let p = Original Price of the watch

p - 0.30p = 84

0.70p = 84

p = 84 ÷ 0.70

p = 120

The original price of the watch is $120.

Answer:

The original price was $120.

Step-by-step explanation:

Let the original price of the watch be w.  

Then the discount is 0.30w and the discounted price is (1-0.30)w, or 0.70w.

Writing an equation in w, we get 0.70w = $84.

Solving this for w, we divide both sides by 0.70:

w = (84)/0.70 = $120

The original price was $120.

Answer:

s = -3

Step-by-step explanation:

note: no matter what you do to an equation, as long as you repeat it on both sides the equation will still be true.

6 = 4s + 18

subtract 18 from both sides of the equation

6 - 18 = 4s + 18 - 18

6 - 18 = 4s

-12 = 4s

divide both sides of the equation by 4

-12/4 = 4s/4

-12/4 = s

The equivalent operation is: b = (a < 5) ? 12 : (d = 30);

The original if/else statement is:

if (a < 5)

   b = 12;

else

   d = 30;

In this statement, the condition (a < 5) is evaluated. If the condition is true (i.e., if the value of a is less than 5), then the statement b = 12; is executed. Otherwise, if the condition is false (i.e., if the value of a is greater than or equal to 5), then the statement d = 30; is executed.

The equivalent operation using the conditional (ternary) operator is:

b = (a < 5) ? 12 : d = 30;

In this statement, the condition (a < 5) is evaluated. If the condition is true, the value 12 is assigned to b. This is indicated by ? in the statement. The : separates the true and false cases.

If the condition is false (i.e., if the value of a is greater than or equal to 5), the value 30 is assigned to d. This is the value assigned after the : in the statement.

The ternary operator statement (a < 5) ? 12 : d = 30; achieves the same outcome as the original if/else statement, providing an alternative way to write the logic based on the condition a < 5.

Answer:

i. The angle measure of Imogen's leftover should not be larger than \(98^{o}\)

ii. The maximum number of slices that Imogen can fit is 2.

Step-by-step explanation:

The leftover in Madeline's box forms angle = 203°

The leftover in Tyra's box forms angel = \(59^{o}\)

Sum of angles formed = 203° + \(59^{o}\)

                                      = \(262^{o}\)

Given that one box =  1 full circle of 360°. Then,

the angle formed by the leftover in Imogen's box = 360° - \(262^{o}\)

                                                       = \(98^{o}\)

Thus, the angle measure of Imogen's leftover slices should not be larger than \(98^{o}\).

If each slice has an angle of \(40^{o}\), the maximum number of slice that Imogen can fit = \(\frac{98}{40}\)

          = 2 \(\frac{9}{20}\)

          = 2.45

The maximum number of slices that Imogen can fit is 2.

Using the concept of bearing and displacement, the seal is 3.276km from it's starting point.

To determine how far north the seal is from its starting point, we need to find the northward component of its displacement.

Given that the seal swims on a bearing of 055 degrees, we can consider this as the direction with respect to true north. To find the northward component, we need to calculate the sine of the angle.

The northward component can be found using the formula:

Northward component = Displacement * sin(Bearing)

In this case, the displacement is 4 km, and the bearing is 055 degrees.

Northward component = 4 km * sin(55 degrees)

Using a calculator, we find that sin(55 degrees) ≈ 0.8192.

Northward component ≈ 4 km * 0.8192

Northward component ≈ 3.276 km

Therefore, the seal is approximately 3.2768 km north of its starting point.

The rule of depreciation function for the machine is f(x) = 146600 - (146600 - 55320) * (x / 8). The machine will be worth approximately $89,521.88 after 5 years.

The rule of depreciation function for the machine can be determined by using the formula for linear depreciation. Linear depreciation assumes that the value of the machine decreases evenly over time. The formula for linear depreciation is:

f(x) = V - (V - S) * (x / n)

Where:

f(x) is the value of the machine at a given time x

V is the initial value of the machine (in this case, $146,600)

S is the scrap value of the machine (in this case, $55,320)

x is the time period in years

n is the total depreciation period in years (in this case, 8 years)

Therefore, the rule of depreciation function for this machine would be:

f(x) = 146600 - (146600 - 55320) * (x / 8)

The domain of the depreciation function represents the valid input values for the time period x. In this case, the machine will be depreciated over an 8-year period. Therefore, the domain of the function is the set of real numbers from 0 to 8, inclusive.

To determine the value of the machine after 5 years, we can substitute x = 5 into the depreciation function:

f(5) = 146600 - (146600 - 55320) * (5 / 8)

Simplifying the equation, we get:

f(5) = 146600 - 91325 * (5 / 8)

     = 146600 - 57078.125

     ≈ $89521.88

Therefore, the machine will be worth approximately $89,521.88 after 5 years.

In summary, the rule of depreciation function for the machine is f(x) = 146600 - (146600 - 55320) * (x / 8). The domain of the function is the set of real numbers from 0 to 8, inclusive. The machine will be worth approximately $89,521.88 after 5 years.

For the angular velocity of the gear, you'll need to gather relevant information about the gear, calculate the linear velocity, and use the formula = v / r. The velocity of the center "O" is always 0 as it does not move linearly.

To determine the angular velocity and the velocity of the center 'O' of the gear at the given instant, you will need to follow these steps:

Step 1: Identify the relevant information.
First, gather information about the gear, such as its radius, the speed at which it is rotating, and any other relevant details. To determine the angular velocity of the gear and the velocity of its center at the instant shown, we need to know the radius of the gear and the speed of its rotation. The angular velocity of the gear can be calculated by dividing the speed of rotation by the radius of the gear. The velocity of the center of the gear can be calculated by multiplying the angular velocity by the radius of the gear.

Step 2: Calculate the angular velocity.
Angular velocity () can be calculated using the formula  = v / r, where 'v' is the linear velocity at the edge of the gear and 'r' is the radius of the gear.

Step 3: Find the linear velocity at the edge of the gear.
This can typically be given or can be determined based on the information provided.

Step 4: Calculate the angular velocity.
Plug the values of linear velocity (v) and radius (r) into the formula  = v / r to find the angular velocity.
Angular velocity = (speed of rotation) / (radius of gear)
Velocity of center = (angular velocity) x (radius of gear)

Step 5: Determine the velocity of the center 'O'
Since the center 'O' of the gear is the point around which the gear rotates, its velocity is 0, as it does not move linearly.

In summary, to find the angular velocity of the gear, you'll need to gather relevant information about the gear, calculate the linear velocity, and use the formula  = v / r. The velocity of the center "O" is always 0 as it does not move linearly.
