Answer:

0.6832

Step-by-step explanation:

Given :

Mean, m = 52

Standard deviation, s = 7

-1.2 standard deviation of average = 57 - 1.2(7) = 57 - 8.4 = 48.6

2 standard deviations of average = 57 + 2(7) = 57 + 14 = 71

Zscore = (48.6 - 52) / 7 = - 0.486

Zscore = (71 - 52) / 7 = 2.714

P < -0.486) = 0.31348

P < 2.714 = 0.99668

P < 2.714 - P < -0.486 = (0.99668 - 0.31348) = 0.6832

When looking at 1:2 you can see that 1 + 1 = 2 from this we can easily tell that the answer will be like this. 8 + 8 = 16 and 9 + 9 = 18 but 4 + 4 = 8 and not 6.

Once we have categorized an object, our memory of the object increasingly resembles the category is B) prototype. This means that when we categorize an object, our memory of it begins to resemble the prototype or typical example of that category. For example, if we categorize a bird as a robin, our memory of the bird will increasingly resemble the characteristics of a typical robin.

This happens because our brain uses prototypes as a shortcut to process information and make sense of the world around us. We use prototypes to quickly identify objects and make assumptions about their characteristics based on their category.

our memory of an object after categorization is influenced by the prototype of the category. This helps us to quickly process and make sense of information, but it can also lead to errors and biases in our thinking.


A prototype is a mental image or best example of a category. When we categorize an object, our memory of the object increasingly resembles the prototype because we tend to recall the most representative or typical example of the category.

Once we categorize an object, our memory of the object becomes more like the prototype, which is the best example of the category. This is because we tend to remember the most representative or typical examples of a category.

The amount of space within the cylinder not taken up by the tennis balls is 18.9 \(inches^3\)

The volume of a tennis ball:

The circumference of the tennis ball is 8 inches.

The tennis ball is the form of sphere whose circumference is given by formula \(2\pi r\) , where r is the radius.

Thus, if r is the radius then according to condition,

\(2\pi r\)  = 8 or

r = 8/2\(\pi\) inches.

Now, the volume of the sphere of radius r is \(\frac{4}{3}\pi r^3\) hence, find the volume of the given tennis ball by substituting r  = 8/2\(\pi\) inches in \(\frac{4}{3}\pi r^3\) and simplify:

Volume = \(\frac{4}{3} \pi\) × \((\frac{8}{2\pi } )^3\)

Volume = 8.65 \(inches^3\)

Hence the required volume of the tennis ball is 8.65 \(inches^3\)

The volume of three tennis balls is (3 × 8.65) \(inches^3\)  = 25.96 \(inches^3\)

Find the volume of the cylinder:

The volume of the cylinder with radius r units and height h units is given by  \(\pi r^2h\) Hence the volume of the given cylinder with radius 1.32 inches , 8.2 height inches is:

\(\pi (1.32)^2\) × 8.2

= 3.14 × \((1.32)^2\) × 8.2

= 44.86 \(inches^3\)

Hence the volume of the cylinder is 44.86 \(inches^3\)

Find the amount of space within the cylinder not taken up by the tennis balls.

The required volume can be obtained by subtracting the volume three tennis balls from the volume of the cylinder as follows:

Volume of cylinder - volume of three tennis balls = (44.86 - 25.96) = 18.9 \(inches^3\)

Hence, the amount of space within the cylinder not taken up by the tennis balls is 18.9 \(inches^3\).

First you have to find the radius.

3.5 divide by 2 = 1.75

v= 4/3 pi r ^3

v = 4/3 (3.14) (1.75)^3

v= 4/3 (3.14) (5.36)

v= 4/3 (16.83)

v= 4/3 (16.83) = (4/3) (16.83/1)

v= (4/3) (16.83/1) = 67.32/3 = 22.44

Optimal path and trajectory planning for serial robots involves finding the most efficient and effective way for a robot to move from one position to another. This is important in tasks such as industrial automation, where time and energy efficiency are crucial.

Inverse kinematics is a mathematical technique used to determine the joint angles required to achieve a desired end effector position and orientation. It is particularly useful for redundant robots, which have more degrees of freedom than necessary to perform a task. Inverse kinematics allows for optimizing the robot's motion to avoid obstacles, minimize joint torques, or maximize performance metrics.

Fast solutions of parametric problems involve efficiently solving optimization or control problems with varying parameters. This is often necessary in real-time applications where the robot's environment or task requirements may change.

In summary, optimal path and trajectory planning for serial robots involves using inverse kinematics to determine joint angles, especially for redundant robots. Fast solutions of parametric problems enable real-time adaptation to changing conditions. These techniques improve the efficiency and effectiveness of robotic systems.

Hello There!

\(GraceRosalia\) is here to help you!

We are given that

d=8 in.

We know that the radius is 1/2 of d or r=d/2. So the radius is 4.

However, we have to find the area.

The formula for the area of a circle is:

A=\(\pi\)\(r^{2}\)

We know that r=4, so all we have to do is plug it into the formula:

A=\(\pi (4)^{2}\)

Remember that only the radius is squared.

A=\(\pi *16\)

A=50.265

Let's round to the nearest tenth:

A=50.3

The cost of the calculator before the total is $24.95

From the question, we have the following parameters that can be used in our computation:

Total cost = $28.19

Tax = 13%

Using the above as a guide, we have the following:

Total cost = Initial cost * (1 + Tax)

substitute the known values in the above equation, so, we have the following representation

Initial cost  * (1 + 13%) = 28.19

So, we have

Initial cost   = 28.19/(1.13)

Evaluate

Initial cost = 24.95

Hence, the cost of the calculator before the total is $24.95

The solution to the original equation is approximately 1.4422.

To continue with the bounds found in part d, we need to use the interval [1.4, 1.5] as the initial approximation for the next iteration. Using the Newton-Raphson method, we get the following approximations:

- Iteration 2: x1 = 1.4428
- Iteration 3: x2 = 1.4422

Based on these two iterations, we can conclude that the solution to the original equation is approximately 1.4422. This is because the difference between the approximations in the last two iterations is only 0.0006, which is a small enough difference to suggest that the approximation has converged to a solution.

In other words, the Newton-Raphson method has been successful in finding a solution to the equation f(x) = x^3 - x^2 - x - 1 = 0 within the given interval [1.4, 1.5]. The method works by using the tangent line to the graph of f(x) at each iteration to approximate the root of the equation. By repeating this process, we are able to get closer and closer to the actual solution.

The number of ways a six-sided die can be constructed with different markings on each side is 720.

If we have a six-sided die, each side can be marked differently with dots. This means that we can have six different options for the first side, five different options for the second side (since one of the dots has already been used), four different options for the third side (since two of the dots have already been used), three different options for the fourth side, two different options for the fifth side, and only one option left for the sixth side.
Therefore, to find the number of ways a six-sided die can be constructed if each side is marked differently with dots, we need to multiply all of these different options together. That is, we need to find the product of 6 x 5 x 4 x 3 x 2 x 1, which is equal to 720.
Therefore, there are 720 different ways that a six-sided die can be constructed if each side is marked differently with dots. This is because there are 720 different permutations of six objects, where each object can only appear once, and the order matters.

To simplify the expression 48 + x + 30 - 3(3x + 2), we can follow the order of operations (PEMDAS) and combine like terms:

48 + x + 30 - 3(3x + 2)

First, simplify the expression within the parentheses:

= 48 + x + 30 - 9x - 6

Next, combine like terms:

= (48 + 30) + (x - 9x) - 6

= 78 + (-8x) - 6

= -8x + 72

So the simplified expression is -8x + 72.

Step-by-step explanation:

Melanie's account balance after t years is, A = 500 x \((1 + 0.00425)^{4t\).

Compound interest is when you receive interest on both your interest income and your savings.

Given:

Initial deposit = $ 500

Interest rate = 1.7 % = 0.017/4 = annual compounded quarterly

Now, Account balance = Initial deposit x \((1 + r)^{4t\)

                                   A = 500 x \((1 + 0.00425)^{4t\)

Where:

A = Account balance

4t = Number of quarters (4 x Number of t years)

Suppose we want to calculate the account balance after 4.5 years, then we substitute this way:

A = 500 x \((1 + 0.00425)^{4(4.5)\)
