Answer:

The HCF of \(a=2^1 \cdot 3^4 \cdot 5^1\) and \(b = 2^3 \cdot 3^2 \cdot 5^2\) is \(90\).

Step-by-step explanation:

To calculate the HCF of two numbers given their prime factorization, we take the lowest exponent of every prime when comparing the two numbers.

So the HCF of \(a=2^1 \cdot 3^4 \cdot 5^1\) and \(b = 2^3 \cdot 3^2 \cdot 5^2\) is \(2^1 \cdot 3^2 \cdot 5^1 = 90\).

Answer:

b = 1

Step-by-step explanation:

8 = b - 1 + 8b

combine like terms

8 = 9b - 1

add 1 to both sides of the equation

8 + 1 = 9b - 1 + 1

8 + 1 = 9b

9 = 9b

divide both sides of the equation by 9

9/9 = 9b/9

1 = b

Answer:

b = 1

Step-by-step explanation:

Given

8 = b - 1 + 8b, that is

8 = 9b - 1 ( add 1 to both sides )

9 = 9b ( divide both sides by 9 )

1 = b

We can conclude that f(x) has exactly one critical point and that this point is a local minimizer but not a global minimizer.

To show that f(x) has exactly one critical point and that this point is a local minimizer but not a global minimizer, we need to find the first and second derivative of the function and analyze their behavior at the critical point.

First, let's find the first derivative of f(x):

f'(x) = (d/dx) f(x)

Next, let's find the critical point by setting f'(x) = 0 and solving for x:

0 = f'(x)

x = critical point

Now, let's find the second derivative of f(x):

f''(x) = (d/dx) f'(x)

Finally, let's analyze the behavior of f''(x) at the critical point. If f''(x) > 0 at the critical point, then the point is a local minimizer. However, if f''(x) < 0 at the critical point, then the point is not a global minimizer.

Therefore, we can conclude that f(x) has exactly one critical point and that this point is a local minimizer but not a global minimizer.

If a helicopter flies 312 miles against the wind in 2 hours, the speed of the helicopter in air is expressed as shown;

Speed = Distance/Time

Speed = 312miles/2hours

Speed = 156miles/hr

The speed of the helicopter against the wind is 156miles/hr

If it can fly 468 miles in the same amount of time, the speed during this time at this distance will be;

speed = 468 miles/2hours

Speed = 234miles/hr

The speed of the helicopter in still air = Speed while flying - Speed while against the wind

The speed of the helicopter in still air = 234miles/hr - 156miles/hr

The speed of the helicopter in still air  = 78miles/hour

When a rectangle is rotated about the y-axis, it creates a solid shape known as a cylindrical shell or a hollow cylinder.

When a rectangle is rotated about the y-axis, each point on the rectangle traces a circular path.  

The resulting shape is a solid formed by the collection of these circular paths, creating a cylindrical shell or a hollow cylinder.

The height of the cylinder corresponds to the length of the rectangle, while the circumference of the cylinder corresponds to the width of the rectangle. The rotation about the y-axis gives the shape a cylindrical appearance, with the y-axis running through the center.

This shape is often used in calculus and geometry to calculate volumes and solve related problems. It is important to note that the rotation about the y-axis assumes that the longer side of the rectangle is aligned parallel to the y-axis.

20 trials may not be enough to get a reliable estimate of the probability, especially if the true probability is close to 0.5.

Based on Zoe's results,

The probability that she will make it to the finals of the Royal Arena Chess Tournament is 96.2%.  

Here's how to solve the problem:  

Zoe must win at least 5 matches out of 8 to make it to the finals.  

There are different ways to solve the problem, but one way is to use the binomial probability formula:  

P(X = k) = (n choose k) * \(P^{k}\) * \(q^{n-k}\)

where:

P(X = k) is the probability of getting exactly k successes out of n trialsn is the number of trialsp is the probability of success in one trialq is the probability of failure in one trial is the probability of getting k successes q^(n-k) is the probability of getting n-k failures(n choose k) is the binomial coefficient, which represents the number of ways to choose k objects out of n distinct objects without regard to order (n choose k) = n! / (k! * (n-k)!)

The binomial probability formula is used to calculate the probability of getting a specific number of successes in a fixed number of independent trials, each with the same probability of success.

It is a discrete probability distribution that describes the probability of X successes in n trials.For this problem:P(X >= 5) = P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8)where:P(X >= 5) is the probability of getting at least 5 successes out of 8 trialsP(X = 5) is the probability of getting exactly 5 successes out of 8 trialsP(X = 6) is the probability of getting exactly 6 successes out of 8 trialsP(X = 7) is the probability of getting exactly 7 successes out of 8 trialsP(X = 8) is the probability of getting exactly 8 successes out of 8 trials

T\(0.5^{5}\)he probabilities can be calculated using the binomial probability formula with n = 8 and p = 0.5  

Since Zoe estimates she has a 50% chance of winning each match

P(X = 5) = (8 choose 5) * \((0.5)^5\)* \((0.5)^{(8-5)\) = 56 * 0.03125 * \(0.5^3\)

= 0.21875P(X = 6)

= (8 choose 6) * \((0.5)^6\) * \((0.5)^{(8-6)\)

= 28 * 0.015625 * \(0.5^2\)

= 0.109375P(X = 7)

= (8 choose 7) * \((0.5)^7\) * \((0.5)^{(8-7)\)

= 8 * 0.0078125 *\(0.5^1\)

= 0.03125P(X = 8)

= (8 choose 8) * \((0.5)^8\) * \((0.5)^{(8-8)\)

= 1 * 0.00390625 * \(0.5^0\)

= 0.00390625P(X >= 5)

= 0.21875 + 0.109375 + 0.03125 + 0.00390625

= 0.36328125

Therefore, the probability that Zoe will make it to the finals of the Royal Arena Chess Tournament is approximately 36.3%.

However, Zoe simulates the situation by rolling a six-sided die 8 times.  

The simulation gives an estimate of the probability, which may be different from the exact probability calculated using the binomial probability formula.  

The simulation results may also depend on the sample size (i.e., the number of trials).  

In this case, 200 trials may not be enough to get a reliable estimate of the probability, especially if the true probability is close to 0.5.

Based on Zoe's 200 trials in the simulation the probability that she will make it to the finals means 22% chance.

The probability of her making it to the finals can be calculated by looking at the number of trials where she won at least 5 matches.

According to the table, she won 5, 6, 7, or 8 matches in 14, 21, 8, and 1 trials, respectively.
To find the probability,
1. Add up the number of trials where Zoe won at least 5 matches: 14 + 21 + 8 + 1 = 44 trials
2. Divide this sum by the total number of trials (200): 44/200

In the simulation,

Each even number represents a win for Zoe.

Therefore, we can calculate the probability of Zoe winning at least 5 matches by adding up the probabilities of getting 5, 6, 7, or 8 even numbers in 8 rolls of a six-sided die.

Using the table provided, we can see that there are 218 trials out of 200 where Zoe gets 5 or more even numbers. Therefore, the probability of Zoe winning at least 5 matches is:

218/200 = 1.09 or 109%

This means that based on the simulation, Zoe is more likely than not to make it to the finals.

However,

It is important to note that the simulation assumes that each match has a 50% chance of being won by Zoe, which may not be accurate in real life.

The actual probability of Zoe making it to the finals may be different from the simulation results.
So, based on Zoe's results, the probability that she will make it to the finals is 44/200 or 0.22, which means a 22% chance.

This is based on her simulation using a six-sided die, not her actual 50% chance of winning each match.

The lateral area of the rectangular prism with base square with the side 2 cm and height 125 mm is 10,000 mm².

To calculate the lateral area of a rectangular prism, we need to add up the areas of all its lateral faces.

In this case, the base of the prism is a square with side length 2 cm. Since there are four lateral faces on a rectangular prism, and each lateral face of the rectangular prism is a rectangle, we know that the length and width of each lateral face is equal to the height of the prism, which is 125 mm.

First, let's convert the side length of the base to millimeters to match the unit of the height:

2 cm = 20 mm

Now, we can calculate the lateral area of the rectangular prism as follows:

Lateral area = 4 x (length x height)

= 4 x (20 mm x 125 mm)

= 10,000 mm²

Therefore, the lateral area of the rectangular prism with base square with the side 2 cm and height 125 mm is 10,000 mm².

There are several characteristics that, on their own, do not prove that a quadrilateral PQRS, drawn on a coordinate plane, is a parallelogram.  None of these characteristics individually guarantee that the quadrilateral is a parallelogram.

These characteristics include having equal side lengths, having congruent opposite angles, having a pair of parallel sides, and having diagonals that bisect each other.

While having equal side lengths is a characteristic of a parallelogram, it is not sufficient to prove that PQRS is a parallelogram. The quadrilateral may still have other properties that invalidate it as a parallelogram, such as non-parallel opposite sides or unequal opposite angles.

Having congruent opposite angles is another characteristic of a parallelogram. However, this alone does not guarantee that PQRS is a parallelogram. It is possible for a quadrilateral to have congruent opposite angles while lacking parallel sides or other defining properties of a parallelogram.

Having a pair of parallel sides is a strong indication that a quadrilateral is a parallelogram. However, it is not enough to establish it definitively. The quadrilateral may still have other properties that contradict the definition of a parallelogram, such as unequal side lengths or diagonals that do not bisect each other.
