Rounding to the nearest whole number, we would expect approximately 251 Dutch men out of a random sample of 1000 to be taller than 190 cm.

To determine how many Dutch men we would expect to be taller than a certain height out of a random sample of 1000, we can use the normal distribution and the properties of the standard normal distribution. We are given that the average height of Dutch men is 183 cm with a standard deviation of 10.5 cm.

To find the probability of a Dutch man being taller than a certain height, we need to convert that height to a standard score or z-score using the formula:

z = (x - μ) / σ

where x is the height we are interested in, μ is the population mean height of Dutch men, and σ is the population standard deviation of Dutch men.

Once we have calculated the z-score, we can use a standard normal distribution table or calculator to find the probability of a Dutch man being taller than that height.

For example, if we want to find the number of Dutch men we would expect to be taller than 190 cm, we can calculate the z-score as:

z = (190 - 183) / 10.5 = 0.67

Using a standard normal distribution table or calculator, we can find that the probability of a standard normal variable being greater than 0.67 is approximately 0.2514.

To find the number of Dutch men we would expect to be taller than 190 cm out of a sample of 1000, we can multiply the probability by the sample size:

1000 * 0.2514 = 251.4

Complete question is:

Males in the Netherlands are the tallest, on average, in the world with an average height of 183 centimeters (cm) (BBC News website). Assume that the height of men in the Netherlands is normally distributed with a men of 183 cm and standard deviation of 10.5cm. out of a random sample of 1000 dutch men, how many would we expect to be taller than cm (rounded to the nearest whole number)?

Answer:

Step-by-step explanation:

We can start by simplifying the expression using the laws of exponents:

343^(2x) * 49^(-x/2) = 49^(x/2)

We can then simplify further by expressing everything in terms of 7 (since 7 is the common factor of both 343 and 49):

(7^3)^(2x) * (7^2)^(-x/2) = (7^2)^(x/2)

Applying the laws of exponents again, we get:

7^(6x) * 7^(-x) = 7^x

7^(6x - x) = 7^x

7^(5x) = 7^x

Now we can solve for x by equating the exponents on both sides:

5x = x

4x = 0

x = 0

Therefore, the solution to the equation is x = 0.

Answer:

x = 0

Step-by-step explanation:

343^(2x) * 49^(-x/2) = 49^(x/2)

(7^3)^(2x) * (7^2)^(-x/2) = (7^2)^(x/2)

7^(6x) * 7^(-x) = 7^(x)

Now, we can simplify the equation further by combining the like terms on both sides:

7^(6x - x) = 7^(x)

7^(5x) = 7^(x)

We can solve for x by equating the exponents on both sides of the equation:

5x = x

4x = 0

x = 0

Therefore, the solution to the equation is x = 0.

Total distance of 7m, which is the shortest distance between point P and point R.

Distance is the physical separation between two objects or points. It is usually measured in units such as meters, kilometers, feet, miles, or light-years. Distance is a key concept in physics, mathematics, engineering, and other scientific disciplines. It plays an important role in our everyday life, such as when we measure the distance between two cities, two buildings, or two places.

To determine the shortest distance between point P and point R, we need to calculate the distances between each point and then find the shortest path.

First, we need to calculate the distances between each point. Starting with the points closest to point R, we can find the distance between point R and point Q to be 4m. The distance between point Q and point P is 3m, from the given information. To find the distance between point R and point U, we need to calculate the distance between point U and point V which is 10m, and then add 8m to account for the 8m between point R and point V. This gives us a distance of 18m. The distance between point R and point S is 8m, and the distance between point S and point T is 8m.

Next, we need to calculate the shortest path between point P and point R. From point P, the shortest route would be to travel 3m south to point Q, then 4m east to point R. This gives us a total distance of 7m, which is the shortest distance between point P and point R.

Mitchelle will receive R7200 and Angela will receive R10800.

How to find the value of one part by dividing the total amount won by the total number of parts?

To determine how much Mitchelle and Angela will each receive in the ratio of 2:3, we need to first find the total number of parts in the ratio, which is 2 + 3 = 5.

Value of one part = R18000 ÷ 5 = R3600

Therefore, one part of the ratio 2:3 is equal to R3600.

How to find out how much Mitchelle and Angela will each receive?

we can multiply their respective parts by the value of one part:

• Mitchelle's share = 2 parts × R3600 per part = R7200

• Angela's share = 3 parts × R3600 per part = R10800

Therefore, Mitchelle will receive R7200 and Angela will receive R10800.

Answer:

(x, y) = (cos(2π/5), sin(2π/5)) = ((1/4)(-1 + √5), (1/4)(2√5 + 2))

Step-by-step explanation:

In standard position, the initial side of an angle lies on the positive x-axis, and the terminal side rotates counterclockwise from the initial side.

Since the angle measures 2π/5 radians, we need to find the point on the unit circle that is π/5 radians past the positive x-axis.

Let (x, y) be the coordinates of the point on the unit circle where the terminal side intersects. We can use the following trigonometric identities to find the values of x and y:

cos(2π/5) = x

sin(2π/5) = y

These values can be determined using either a calculator or the unit circle. Alternatively, we can use the fact that the angle 2π/5 is a special angle and can be expressed exactly in terms of square roots:

cos(2π/5) = (1/4)(-1 + √5)

sin(2π/5) = (1/4)(2√5 + 2)

Therefore, the exact coordinates of the point where the terminal side intersects the unit circle are

(x, y) = (cos(2π/5), sin(2π/5)) = ((1/4)(-1 + √5), (1/4)(2√5 + 2))

Answer:

The median and mean are two different measures of central tendency that provide different information about a data set. The median is the middle value in a data set, where half of the values are above and half are below. The mean, on the other hand, is the sum of all values divided by the total number of values.

In this case, the median number of reviews is much lower than the mean number of reviews, indicating that there are likely a few very high review counts that are skewing the data towards the higher end. This is because the mean is more affected by extreme values, while the median is not. It is possible that there are a few apps with an extremely large number of reviews, which are driving up the mean.

The mean number of reviews would be significantly higher than the median.

The difference between the median and mean number of reviews can be explained by the fact that some apps have very large numbers of reviews, whereas others have very few. The median is the middle value of the dataset, and does not take into account the outliers, which can have a large effect on the mean. For example, if there is one app with 1 million reviews, the mean number of reviews would be significantly higher than the median.

Number of ways that  can we choose the officers, if individual members are allowed to hold 2 but not all 3 offices is 49,825

One member holds all three offices: There are 25 options for choosing the member who will hold all three offices.

Two members hold two offices each: There are 25 options for choosing the first member, and 24 options for choosing the second member (since one member cannot hold all three offices). Then, for the first member, there are 3 options for which offices they will hold, and for the second member, there are 2 options for which offices they will hold. Here we have to use the permutation. So the total number of ways is

25 × 24 × 3 × 2 = 36,000

Three members hold one office each: There are 25 options for choosing the first member, 24 options for choosing the second member, and 23 options for choosing the third member. So the total number of ways is

There are 40 ways to place three rooks on a 4x5 board so that no rook is threatening another.

To determine this, we can first place the rooks in three distinct rows, which can be done in 4 * 3 * 2 = 24 ways. Then, we can place one rook in each of the five columns in the first row, which leaves only three columns for the second row and two columns for the third row.

Since no two rooks can be in the same column, we have 5 * 3 * 2 = 30 ways to place the remaining two rooks.

Therefore, the total number of arrangements is 24 * 30 = 720, but since each arrangement can be rotated by 90, 180, or 270 degrees, we need to divide by 4 to obtain the final answer of 720/4 = 180, and since there are two ways to arrange the rooks in each row, the final answer is 180/2 = 90.

The weight of each box of cereal must be between 21 and 23 ounces for the case to pass the quality assurance test. We can write this as the compound inequality: 21 < b < 23.

A quality assurance test is a process that is used to evaluate the quality of a product or service. It involves checking whether the product or service meets certain standards or specifications, and identifying any defects or issues that need to be addressed.

Let's start by finding the weight of a single box of cereal. We know that the weight of the entire case is the weight of 11 boxes plus the weight of the cardboard box, or:

Weight of case = 11b + 33

where b is the weight of a single box of cereal.

To pass the quality assurance test, the weight of the case must be greater than 264 ounces and less than 286 ounces. Therefore, we can write a compound inequality for b as follows:

264 < 11b + 33 < 286

Next, we can simplify this compound inequality by subtracting 33 from each term:

231 < 11b < 253

Finally, we can divide each term by 11 to solve for b:

21 < b < 23

Therefore, the weight of each box of cereal must be between 21 and 23 ounces for the case to pass the quality assurance test. We can write this as the compound inequality:

The surface area of the playhouse is 564 square feet.

Frank is building a playhouse for his daughter.

The playhouse is a composite figure with a floor and no windows.

The playhouse is a rectangular prism and a triangular prism.

The formula for the surface area of a rectangular prism is 2lw + 2lh + 2wh,

where l is the length,

w is the width,

and h is the height.

Therefore, the surface area of the rectangular prism portion of the playhouse can be calculated by substituting the given values into the formula.

Surface area of the rectangular prism = 2lw + 2lh + 2wh

For the rectangular prism, l = 10 feet, w = 8 feet, and h = 6 feet.

Substituting the values in the formula.

Surface area of the rectangular prism

= 2lw + 2lh + 2wh

= 2 (10 feet × 8 feet) + 2 (10 feet × 6 feet) + 2 (8 feet × 6 feet)

= 160 feet2 + 120 feet2 + 96 feet2= 376 feet2

The surface area of the rectangular prism of the playhouse is 376 square feet.

The formula for the surface area of a triangular prism is 2lw + lh + ph,

where l is the length, w is the width, h is the height, and p is the slant height.

Therefore, the surface area of the triangular prism portion of the playhouse can be calculated by substituting the given values into the formula.

Surface area of the triangular prism = 2lw + lh + ph

For the triangular prism, l = 8 feet, w = 5 feet, h = 6 feet, and p = 10 feet.

Substituting the values in the formula.

Surface area of the triangular prism = 2lw + lh + ph= 2 (8 feet × 5 feet) + (8 feet × 6 feet) + (10 feet × 6 feet)= 80 feet2 + 48 feet2 + 60 feet2= 188 feet2

The surface area of the triangular prism of the playhouse is 188 square feet.

The total surface area of the playhouse can be found by adding the surface area of the rectangular prism and the surface area of the triangular prism.

Surface area of the playhouse = surface area of rectangular prism + surface area of triangular prism.

The water surface in the conical tank is rising at a rate of approximately 0.16 feet per minute when the water depth is 5 feet.

To solve for this, we can use related rates. Since the tank is being filled with water at a constant rate of 2 ft³/min , we know that the rate of change of the volume of water in the tank is constant. We can use the formula for the volume of a cone to relate the volume of water in the tank to the height of the water in the tank:

V = (1/3) * pi * r² * h

Taking the derivative of both sides with respect to time gives:

dV/dt = (1/3) * pi * r² * dh/dt

We know that dV/dt = 2 ft³/min, r = 2 ft, and h = 5 ft. Solving for dh/dt:

dh/dt = (3 / pi * r²) * dV/dt

dh/dt = (3 / 4 * pi) * 2

dh/dt = 0.16 ft/min

If the probability that a player makes a free throw is 0.4, the probability that they do not make a free throw is 1 – 0.4 = 0.6.

The probability that a player makes three consecutive free throws is 0.4 × 0.4 × 0.4 = 0.064. If a player attempts three free throws, there are three possible outcomes: make all three, miss one and make two, or miss two and make one.

The probability of making all three is 0.064, the probability of missing one and making two is 0.4 × 0.4 × 0.6 + 0.4 × 0.6 × 0.4 + 0.6 × 0.4 × 0.4 = 0.288, and the probability of missing two and making one is 0.6 × 0.6 × 0.4 + 0.6 × 0.4 × 0.6 + 0.4 × 0.6 × 0.6 = 0.432.

Therefore, the probability of leaving the court in three attempts is 0.064 + 0.288 + 0.432 = 0.784. If a player misses all three attempts, they will have to try three more times, and the probability of leaving the court in six attempts is 0.784 + 0.064 × 0.288 × 0.432 = 0.861.

If a player misses all six attempts, they will have to try three more times, and the probability of leaving the court in nine attempts is 0.861 + 0.064 × 0.288 × 0.432 × 0.064 × 0.288 × 0.432 × 0.064 × 0.288 × 0.432 = 0.926.

If a player misses all nine attempts, they will have to try three more times, and the probability of leaving the court in twelve attempts is 0.926 + 0.064 × 0.288 × 0.432 × 0.064 × 0.288 × 0.432 × 0.064 × 0.288 × 0.432 × 0.064 × 0.288 × 0.432 × 0.064 × 0.288 × 0.432 = 0.974.

Since the probability of leaving the court in twelve attempts is greater than 0.9, the probability of leaving the court in ten or fewer attempts is greater than 0.9. Therefore, the probability that a player can leave the court in 10 or fewer attempts is greater than 0.9.

Therefore, the rate of change over the interval [-1, 2] for Function B is 32/3.

In mathematics, a function is a rule that assigns to each input value (also known as the independent variable) a unique output value (also known as the dependent variable). In other words, a function is a relationship between a set of inputs and a set of possible outputs with the property that each input is related to exactly one output. Functions can be represented in various forms such as algebraic expressions, tables, graphs, or even words. Functions play a crucial role in many areas of mathematics, science, and engineering, as they provide a way to model and describe real-world phenomena and relationships between quantities.

Here,

For Function A, the formula is f(x) = 4x + 1. To find the rate of change over the interval [-1, 2], we need to calculate the slope of the line that passes through the points (-1, f(-1)) and (2, f(2)). The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:

slope = (y2 - y1) / (x2 - x1)

Substituting the values for Function A, we get:

slope = (f(2) - f(-1)) / (2 - (-1))

slope = (4(2) + 1 - (4(-1) + 1)) / (2 - (-1))

slope = (9 + 5) / 3

slope = 14/3

Therefore, the rate of change over the interval [-1, 2] for Function A is 14/3.

For Function B, the formula is g(x) = 10x + 2. To find the rate of change over the interval [-1, 2], we need to calculate the slope of the line that passes through the points (-1, g(-1)) and (2, g(2)). The slope of a line passing through two points (x1, y1) and (x2, y2) is given by the formula:

slope = (y2 - y1) / (x2 - x1)

Substituting the values for Function B, we get:

slope = (g(2) - g(-1)) / (2 - (-1))

slope = (10(2) + 2 - (10(-1) + 2)) / (2 - (-1))

a) mv = Mv.

b) The columns of M are dependent where [v1, v2, ..., vn]T is a vector combination

If a matrix M is multiplied by a vector v, the result will be a linear combination of the columns of the matrix. That is, if M is an m×n matrix and v is a vector with n entries, then the product Mv is a linear combination of the columns of M with coefficients from v. Thus, mv = Mv.

If the columns of M are linearly dependent, it implies that they are multiples of each other, i.e., one column is equal to a scalar multiple of another column, which can be written as an equation of the form, ci = aj where c and a are scalar multiples of jth and ith columns of M, respectively.

Hence, when we compute Mv, the linear combination of the columns of M will depend on the scalar multiples c and a.

For instance, let us assume that column j and i of M are linearly dependent. We have;

ci = aj or

M(:,j) = a*M(:,i)

where M(:,j) and M(:,i) represent jth and ith columns of M, respectively. Then, we can express M as;

M = [M(:,1), ..., M(:,j-1), M(:,i), M(:,j+1), ..., M(:,n)] = [M(:,1), ..., M(:,j-1), a*M(:,i), M(:,j+1), ..., M(:,n)]

Thus, we can rewrite the product Mv as;

Mv = [M(:,1), ..., M(:,j-1), a*M(:,i), M(:,j+1), ..., M(:,n)][v1, v2, ..., vn]T

where [v1, v2, ..., vn]T is a vector combination of the columns of M.

Therefore, if a linear combination of the columns of M results in the zero vector, it implies that the columns of M are dependent.

Step-by-step explanation:

Answer:

d ≈ 5.4

Step-by-step explanation:

calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (2, 2 ) and (x₂, y₂ ) = (4, 7 )

d = [tex]\sqrt{(4-2)^2+(7-2)^2}[/tex]

   = [tex]\sqrt{2^2+5^2}[/tex]

  = [tex]\sqrt{4+25}[/tex]

  = [tex]\sqrt{29}[/tex]

The number of nickels Bill has is 10.

Therefore, Bill has 10 nickels and 30 dimes.

The given question is as follows.

Bill has a collection of 40 nickels and dimes.

Together, they add up to $3.50.

Bill have of each coin :

To solve the given problem, let's consider the following steps.

Step 1: Let x be the number of nickels and y be the number of dimes.

Based on the given data, we can form the following two equations:

x + y = 40 ... (1) (because Bill has 40 nickels and dimes)

0.05x + 0.10y = 3.50 ... (2) (because the sum of 40 nickels and dimes is $3.50)

Step 2: Solve the equations (1) and (2) by elimination method by multiplying equation (1) with 0.05 and subtracting it from equation (2).

0.05x + 0.05y = 2 ... (3)0.05x + 0.10y = 3.50 ... (4)

Subtracting equation (3) from equation (4),

we get0.05y = 1.50

Dividing both sides by 0.05, we get

y = 30

Therefore, the number of dimes Bill has is 30.

Step 3: Now, substitute the value of y in equation (1), we get

x + 30 = 40

Subtracting 30 from both sides, we get x = 10.

The area of the shaded region of the circle is 63.24 ft²

We know that the area of a circle of radius R is given by the formula:

Area = pi*R²

Where pi = 3.14

If we have only a section of a circle defined by an angle θ, the area of that section will be:

area = (θ/360°)*3.14*R²

Here we know that the radius is 5 feet, and that AOB (the non-shaded part) is 70°, then we will have:

θ = 360° - 70° = 290°

Then the area of the shaded region is:

area = (290°/360°)*3.14*(5 ft)² = 63.24 ft²
