Answer:

150.72

Step-by-step explanation:

V=πr²h

V=3.14·4²·3

V=3.14·16·3

V=50.24·3

V=150.72

here is a 19.8% probability that for a random sample of 18 days, it will rain exactly 4 of those days.

The meteorologist can use probability to determine the likelihood of it raining on a certain number of days in a random sample of 18 days. Based on the past year's records, the probability of it raining on any given day is 21/365, or approximately 0.0575. Using the binomial distribution formula, the probability of it raining exactly 4 times in a random sample of 18 days is:

P(4) = (18 choose 4) * (0.0575)^4 * (1 - 0.0575)^(18 - 4)
P(4) = 0.198

Therefore, there is a 19.8% probability that for a random sample of 18 days, it will rain exactly 4 of those days.

This probability is based on the assumption that the weather patterns will remain similar to the past year's records.

Answer:

Question 1

The greatest number of treasure chest you can fill = 23

Step-by-step explanation:

Gold coins = 46

Diamonds = 115

Rubies = 184

To determine the greatest number of treasure chests you can fill, find the highest common factors of 46, 115 and 184

46 = 1, 2, 23, 46.

125 = 1, 5, 23, 115

184 = 1,2,4,8,23,46,92,184

The highest common factors of 46, 115 and 184 is 23

The greatest number of treasure chest you can fill = 23

Number of gold coins in each chest = 46/23

= 2

Number of diamonds in each chest = 115 / 23

= 5

Number of rubies in each chest = 184 /23

= 8

Question 2

Nickels = 246

Dimes = 312

Quarters = 204

Find the highest common factor of 246, 312, 204

246 = 1, 2, 3, 6, 41, 82, 123, 246

312 = 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312.

204 = 1, 2, 3, 4, 6, 12, 17, 34, 51, 68, 102, 204

The highest common factor of 246, 312, 204 is 6

How many are in your group?

6 members

There are 6 members in your group that each person got the same exact amount of each coin with no coins remaining.

Number of nickels each person receive = 246 / 6

= 41

Number of dimes each person receive = 312 / 6

= 52

Number of quarters each person receive = 204 / 6

= 34

The mean value theorem states that if a function f(x) is continuous on the interval [a, b] and differentiable on (a, b), then there exists a value c in (a, b) such that:

f'(c) = (f(b) - f(a))/(b - a)

In this case, the interval is [2, 6]. So, we need to find the value(s) of c that satisfy:

f'(c) = (f(6) - f(2))/(6 - 2)

We can make an estimate based on the graph of the function.

If the graph of f(x) is a straight line between (2, f(2)) and (6, f(6)), then the derivative is constant over the interval [2, 6]. In this case, we can use the formula:

f'(c) = (f(6) - f(2))/(6 - 2) = (y2 - y1)/(x2 - x1)

where (x1, y1) = (2, f(2)) and (x2, y2) = (6, f(6)).

Solving for c, we get:

c = (x1 + x2)/2 = (2 + 6)/2 = 4

This is the only value of c that satisfies the conclusion of the mean value theorem in this case.

If the graph of f(x) is not a straight line, then we cannot make a simple estimate for c based on the graph alone.
To estimate the value(s) of c that satisfy the conclusion of the Mean Value Theorem (MVT) on the interval [2, 6], you need to follow these steps:

1. Identify the function, f(x), that you're working with.

2. Ensure the function is continuous on the interval [2, 6] and differentiable on the open interval (2, 6). This is required for MVT to be applicable.

3. Calculate the average rate of change (mean value) of the function over the interval [2, 6] by using the formula (f(6) - f(2)) / (6 - 2).

4. Take the derivative of the function, f'(x).

5. Set f'(x) equal to the mean value calculated in step 3 and solve for the value(s) of x, which will give you the value(s) of c that satisfy the MVT.

Let's call x the pure antifreeze in gallons. This means 4 + x represents the new quantity of pure antifreeze.

According to the problem, 25% of the solution represents 4 gallons and 50% of the solution represents the new quantity of antifreeze.

Based on the given information, we can express the following.

Let's solve for x.

(a) Cylinder: x² + y² = r²

The Gauss map G sends each point on the cylinder to a point on the unit sphere Σ. For the cylinder, the unit normal vector field U will be perpendicular to the tangent plane at each point on the cylinder's surface. Since the cylinder is symmetric about the z-axis, the normal vector U will also be perpendicular to the z-axis.

Therefore, the Gauss map G(M) for the cylinder will send each point on the cylinder to a point on the unit sphere Σ such that the x and y coordinates of the points on the sphere will correspond to the x and y coordinates of the points on the cylinder. The z-coordinate on the sphere will depend on the height of the point on the cylinder.

(b) Cone: z = √(x² + y²)

For the cone, the unit normal vector field U will be perpendicular to the tangent plane at each point on the cone's surface. The Gauss map G(M) will map each point on the cone to a point on the unit sphere Σ such that the x and y coordinates of the points on the sphere will correspond to the x and y coordinates of the points on the cone. The z-coordinate on the sphere will depend on the height and distance from the origin of the point on the cone.

(c) Plane: x + y + z = 0

For the plane, the unit normal vector field U will be constant and perpendicular to the plane. The Gauss map G(M) will map each point on the plane to a single point on the unit sphere Σ. The direction of the normal vector U will determine the point on the sphere to which each point on the plane is mapped.

(d) Sphere: (x-1)² + y² + (z+2)² = 1

For the sphere, the unit normal vector field U will be perpendicular to the tangent plane at each point on the sphere's surface. The Gauss map G(M) will map each point on the sphere to a point on the unit sphere Σ such that the x, y, and z coordinates of the points on the sphere are normalized to lie on the unit sphere. The Gauss map for the sphere will preserve the spherical symmetry and map each point to its corresponding point on the unit sphere.

Answer:

Approximately 2.3 hours after 12 noon

Step-by-step explanation:

We are given
Stock A price at 9AM = $13.45
It increases by $0.08 per hour

Stock B at noon = $14.20
It decreases by $0.14 each hour

We have to find when the two prices will be the same.

Since the base time references are different - 9am for A and noon for B, we have to establish the same time reference

Let's do this by finding the price of stock A at noon, then we have the same time base reference of noon

9am - noon = 3 hours

In 3 hours stock A would have risen by 0.08 x 3 = $0.24

Price of stock A at noon is 13.45 + 0.24 = $13.69

Thereafter stock A continues to increase by the same rate of $0.08 per hour
The equation to model stock A price starting at noon is
13.69 + 0.08x where x is the number of hours elapsed after 12 noon

Stock B price is $14.20 at 12 noon and decreases by $0.14 per hour
Equation to model stock B price after 12 noon is

14.20 - 0.14x where x is the elapsed time after 12 noon

For both prices to be the same after the same x hours, we have
13.69 + 0.08x = 14.20 - 0.14x

Solving for x will tell us how many hours it will take for both stock prices to be the same

Solving
13.69 + 0.08x = 14.20 - 0.14x

So the two stock prices will be the same 2.3 hours after 12 noon or about 2 hours and 18 minutes after 12 noon or roughly around 2:18pm

I got 18 minutes by multiplying 0.3 x 60 = 18

ANSWER and EXPLANATION

B. We are to describe the relationship between bridge length and breaking weight.

To do this, we need to check the graph.

In doing that, we will see that the breaking weight appears to decrease as the Bridge length increases.

We can conclude then that the breaking weight and bridge length have an inverse relationship.

That is shown in the graph.

The highest value of the breaking weight is 14 and that is when the value of bridge length is at its lowest (4).

The lowest value of the breaking weight is 3 and that is when the value of the bridge length is at its highest (11)

Hence, there is an inverse relationship between them.4)

The expected number of games they'll play before Diesel wins six games is 4.

a. The probability that Diesel will win her 6 th game on the 18th game is the probability that Diesel will win exactly 5 of the first 17 games and then win the 18 th game. The probability that Diesel wins any particular game is 1 / 4, so the probability that she wins 5 of the first 17 games is:

\($$\left(\begin{array}{c}17 \\5\end{array}\right)\left(\frac{1}{4}\right)^5\left(\frac{3}{4}\right)^{12} \approx 0.202$$\)

Then, the probability that Diesel wins the 18th game is 1 / 4. Therefore, the probability that Diesel will win her 6 th game on the 18th game is:

\($$0.202 \cdot \frac{1}{4}=0.0505$$\)

b. We can approach this problem using the concept of a geometric distribution. Let X be the number of games they play before Diesel wins 6 games. Then, X has a geometric distribution with parameter p=1 / 4, since the probability that Diesel wins any particular game is 1 / 4.

The expected value of a geometric distribution with parameter p is:

\(E(X)=\frac{1}{p}=\frac{1}{1 / 4}=4$$\)

Therefore, the expected number of games they'll play before Diesel wins six games is 4 .

Step-by-step explanation:

The gas station serves 16 vehicles per hour, and 72 vehicles arrive in 4 hours. The vehicles will spend 4.50 hours at the gas station.



To find the total time the vehicles will spend at the gas station, we need to calculate the total number of vehicles that arrive and then divide it by the rate at which the gas station serves vehicles.

Given:

Arrival rate: 18 vehicles per hour

Service rate: 16 vehicles per hour

Time: 4 hours

First, let's calculate the total number of vehicles that arrive during the 4-hour period:

Total number of vehicles = Arrival rate * Time

                      = 18 vehicles/hour * 4 hours

                      = 72 vehicles

Since the gas station can serve 16 vehicles per hour, we can determine the time it takes to serve all the vehicles:

Time to serve all vehicles = Total number of vehicles / Service rate

                         = 72 vehicles / 16 vehicles/hour

                         = 4.5 hours

Therefore, the vehicles will spend 4.5 hours at the gas station. Rounded to 2 decimal places, the answer is 4.50 hours.

The width of the new rectangular field would be 0 meters, which means it would essentially be a line segment.

To find the length and width of another rectangular field that has the same perimeter but a larger area, we can use the following steps:

1. Calculate the perimeter of the given rectangular field:

  Perimeter = 2 * (Length + Width)

            = 2 * (120 meters + 80 meters)

            = 2 * 200 meters

            = 400 meters

2. Divide the perimeter by 2 to find the equal sides of the new rectangular field. Since the perimeter is divided equally into two sides, each side would be half of the perimeter length:

  Side length = Perimeter / 2

             = 400 meters / 2

             = 200 meters

3. Now, we have the side length of the new rectangular field. However, we need to determine the length and width that would yield a larger area. One way to achieve this is to make one side longer and the other side shorter.

4. Let's assume the length of the new rectangular field is 200 meters. Since both sides have the same length, the width can be calculated using the formula for the perimeter:

  Width = Perimeter / 2 - Length

        = 400 meters / 2 - 200 meters

        = 200 meters - 200 meters

        = 0 meters

5. Therefore, the width of the new rectangular field would be 0 meters, which means it would essentially be a line segment. However, note that the question asks for a rectangular field with a larger area. Since the width cannot be zero, we can conclude that it is not possible to have a rectangular field with the same perimeter but a larger area than the given field.

In summary, it is not possible to find another rectangular field with the same perimeter but a larger area than the rectangular field with dimensions 80 meters wide and 120 meters long.

To find two positive numbers with a product of 324 and whose sum is a minimum, we can use the fact that the two numbers that minimize the sum are the ones that are closest in value. Therefore, we need to find the square root of 324, which is 18. The two positive numbers are 18 and 18, which are already in increasing order.

We can then use 18 as one of the numbers and divide 324 by 18 to get the other number, which is 18 as well. Therefore, the two positive numbers with a product of 324 and whose sum is a minimum are 18 and 18.

To find two positive numbers with a product of 324 and whose sum is a minimum, follow these steps:

Step 1: Identify the required conditions.
- The product of the two numbers must be 324.
- The sum of the two numbers should be minimized.

Step 2: Write the given conditions as equations.
Let the two numbers be x and y.
- x * y = 324
- We need to minimize x + y.

Step 3: Rewrite one equation to solve for one variable.
From the first equation, we can solve for y:
- y = 324 / x

Step 4: Substitute the solved variable in the second equation.
- x + (324 / x) = x + y

Step 5: Find the minimum sum by considering the factors of 324.
- Factors of 324 are: (1, 324), (2, 162), (3, 108), (6, 54), (9, 36), and (18, 18).

Step 6: Calculate the sums of the factors.
- Sum of (1, 324) = 325
- Sum of (2, 162) = 164
- Sum of (3, 108) = 111
- Sum of (6, 54) = 60
- Sum of (9, 36) = 45
- Sum of (18, 18) = 36

Step 7: Identify the pair with the minimum sum.
The pair (18, 18) has the minimum sum of 36.

So, the two positive numbers are 18 and 18, which are already in increasing order.

The margin of error is 0.1415, where z is the critical value for the desired confidence level,

The margin of error can be calculated using the formula: Margin of error = z * (standard deviation / sqrt(n))

where z is the critical value for the desired confidence level, standard deviation is the population standard deviation (which can be estimated using the sample standard deviation), and n is the sample size.

For a 99.8% confidence level, the critical value is 2.967. Using the given values of x and n, we can calculate the sample proportion as 46/98 = 0.4694.

To estimate the population standard deviation, we can assume that the sample proportion is a good estimate of the population proportion, and use the formula:

standard deviation = sqrt(p*(1-p)/n)

where p is the sample proportion. Substituting the values, we get: standard deviation = sqrt(0.4694*(1-0.4694)/98) = 0.0519

Now we can plug in the values into the margin of error formula to get: Margin of error = 2.967 * (0.0519 / sqrt(98)) = 0.1415

Therefore, the margin of error is 0.1415.

It is important to note that the margin of error represents the amount by which the sample proportion may differ from the population proportion with a certain level of confidence.

It is also important to remember that the margin of error is not the same as the sampling error, which is the difference between the sample mean and the population mean.

The margin of error can be used to determine the sample size required for a given level of precision, or to compare different sample sizes to determine which is more likely to yield a representative sample.
