Step-by-step explanation:

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

Yes, the side lengths 4 8 and 10 can form a triangle. This is because the sum of any two sides in a triangle must be greater than the third side. In this case, 4 + 8 is greater than 10, so it meets the criteria for a triangle. A triangle is defined as a polygon with three sides and three angles, and is one of the basic shapes in geometry. It is also one of the most studied shapes in mathematics due to its wide range of applications. The three angles of a triangle must add up to 180 degrees, and the three sides must satisfy the triangle inequality, meaning that the sum of any two sides must be greater than the third side. Additionally, the interior angles of a triangle are always equal to the sum of two exterior angles. Knowing this, it can be seen that the side lengths 4 8 and 10 can form a triangle, as the sum of any two sides is greater than the third side.

Step-by-step explanation:

a) y = (x + 2)(x + 3)  helps find the x-intercepts most efficiently.

b) y=   \(x^{2} +5x+6\) helps find the y-intercept most efficiently

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

Given that:

a) y= (x+2)(x+3)

i.e., x+2= 0 , x+3 = 0

    x= -2 , x= -3

and, y =  \(x^{2} +5x+6\)

           = (x+2)(x+3)

  x= -2 and y= -3

y = (x + 2)(x + 3) helps to find the x-intercepts most efficiently

Now,

b) y=(x+2)(x+3)

     x =0 , y = 2 x 3 =6

y=   \(x^{2} +5x+6\)

y= 0 +05 x 0 + 6

Step-by-step explanation:

Given expression:

                               10⁻³

To make this expression to a form with  a positive exponent, we have to apply one of the rules of exponents;

          a⁻ᵇ  = \(\frac{1}{a^{b} }\)  

So;

        10⁻³  = \(\frac{1}{10^{3} }\)

It's not entirely clear what the full instructions are, and I wish your teacher posted a diagram of figures A and B. However, I think I know what your teacher is after.

I'm assuming this is pertaining to similar polygons.

The larger figure has a side length of 88 ft and corresponds to the smaller side length of 11 ft. This is a scale factor of 11/88 = 1/8 = 0.125

What it means is that we multiply each larger side length by 1/8 or 0.125 to get the smaller corresponding side length. In other words, 88*(1/8) = 11

Square this linear scale factor to get the area scale factor

(1/8)^2 = (0.125)^2 = 0.015625

This value of 0.015625 is the area scale factor. We multiply this by the area of figure A to get

4928*0.015625 = 77

This is how your teacher got 77 as the final answer for figure B.

------------------------------------------------------

Admittedly this concept is a bit confusing at first.

Let's do another example.

Consider a 2 by 3 rectangle of area 2*3 = 6 square units.

Now apply a linear scale factor of 4 to quadruple each side. We get a 8 by 12 rectangle of area 8*12 = 96.

Notice the jump from 6 to 96 is "times 16" (since 96/6 = 16) and it's no coincidence that 16 is 4^2, i.e. the result of squaring the linear scale factor.

new area = (area scale factor)*(old area)

new area = 16*(old area)

new area = 16*6

new area = 96

This shows that 16 is the area scale factor.

The answer to (c) is ||4v — 4w|| ≈ 27.07.

Given that || v || = 3, || w || = 3, and the angle between v and w is 2.8 radians. We can calculate the following:(a) v. w = ?The dot product of two vectors is defined as the product of their magnitudes and the cosine of the angle between them.

Therefore, v.w = ||v|| ||w|| cos θWhere, θ is the angle between v and w. So, v.w = 3×3 cos(2.8) ≈ -3.20 Therefore, v.w ≈ -3.20.(b) ||1v + 4w|| = ?

The magnitude of the vector ||1v + 4w|| can be calculated as follows:||1v + 4w|| = √((1v + 4w).(1v + 4w))= √(1v.1v + 8v.w + 16w.w) Substitute the value of v.w we obtained above and calculate||1v + 4w|| = √(9 + 8×(-3.20) + 16×9)≈ 9.97

Therefore, ||1v + 4w|| ≈ 9.97.(c) ||4v — 4w|| =Similarly, the magnitude of the vector ||4v — 4w|| can be calculated as follows:

||4v — 4w|| = √((4v — 4w).(4v — 4w))= √(16v.v — 32v.w + 16w.w) Substitute the values of v.w and ||v|| we obtained above and calculate||4v — 4w|| = √(16×9 — 32×(-3.20) + 16×9)≈ 27.07 Therefore, ||4v — 4w|| ≈ 27.07.

The answer to (a) is v.w ≈ -3.20. The answer to (b) is ||1v + 4w|| ≈ 9.97. The answer to (c) is ||4v — 4w|| ≈ 27.07.

The equation relating x, y, and z is:

z = 0.5 * x * y.

In the given problem, the relationship between x, y, and z can be expressed by the equation z = k * x * y, where k represents the constant of proportionality. By substituting the values of x = 4 and y = 5, when z is equal to 10, we can determine the value of the constant of proportionality, k, and further define the relationship between the variables.

To find the constant of proportionality, we substitute the known values of x = 4, y = 5, and z = 10 into the equation z = k * x * y. This gives us the equation 10 = k * 4 * 5. By simplifying the equation, we have 10 = 20k. To isolate k, we divide both sides of the equation by 20, resulting in k = 0.5. Therefore, the equation relating x, y, and z is z = 0.5 * x * y, meaning that z is directly proportional to the product of x and y with a constant of proportionality equal to 0.5.

Let q be the number of quarters and d be the number of dimes.

We have q + d = 32 and $0.25q + $0.10d = $5.

=> 5q + 2d = 100 and q + d = 32

Therefore we get q = 12 and d = 20. (12 quarters and 20 dimes)

The number of coins of quarters and dimes will be 12 and 20, respectively.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

A collection of quarters and dimes has a total value of $5 and contains 32 coins.

Let 'x' be the number of quarters and 'y' be the number of dimes. Then the equations are given as,

x + y = 32                      ...1

0.25x + 0.10y = 5         ...2

From equations 1 and 2, then we have

0.25 x + 0.10 (32 - x) = 5

0.25 x + 3.2 - 0.10 x = 5

0.15 x = 1.8

x = 1.8 / 0.15

x = 12

Then the value of the variable 'y' is given as,

12 + y = 32

y = 32 - 12

y = 20

The number of coins of quarters and dimes will be 12 and 20, respectively.

In summary, the slope of the line is -6, and the y-intercept is (0, -2).

To find the slope and y-intercept of the line y = -6x - 2, we can compare it to the slope-intercept form of a linear equation, which is y = mx + b. In this form, "m" represents the slope, and "b" represents the y-intercept.
For the given equation y = -6x - 2:
1. Identify the slope (m): The coefficient of the x term, which is -6, represents the slope. Therefore, the slope (m) is -6.
2. Identify the y-intercept (b): The constant term, which is -2, represents the y-intercept. To express the y-intercept as a coordinate (0, b), substitute 0 for the x value. So the y-intercept coordinate is (0, -2).

Question 3: True

Question 4: False

Question 5: True

If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c.

This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.

Question 3: If f'(c) < 0 then f(x) is decreasing and the graph of f(x) is concave down when x = c.

True

When the derivative of a function, f'(x), is negative at a point c, it indicates that the function is decreasing at that point. Additionally, if the second derivative, f''(x), exists and is negative at x = c, it implies that the graph of f(x) is concave down at that point.

Question 4: A local extreme point of a polynomial function f(x) can only occur when f'(x) = 0.

False

A local extreme point of a polynomial function can occur when f'(x) = 0, but it is not the only condition. A local extreme point can also occur when f'(x) does not exist (such as at a sharp corner or cusp) or when f'(x) is undefined. Therefore, f'(x) being equal to zero is not the sole requirement for a local extreme point to exist.

Question 5: If f'(x) > 0 when x < c and f'(x) < 0 when x > c, then f(x) has a maximum value when x = c.

True

If the derivative of a function, f'(x), is positive for values of x less than c and negative for values of x greater than c, then it indicates a change in the slope of the function. This change from positive slope to negative slope suggests that the function has a maximum value at x = c. This is because the function is increasing before x = c and decreasing after x = c, indicating a peak or maximum at x = c.

If we closely observe the value of the y-coordinate of the image B'(x, 20), we can see that the y-coordinate of the image B' is 4 times the y-coordinate of the original point (0, 5).

i.e. y → 5×4 =20

It means the coordinates of the image B'(x, 20) can be determined by dilating the original point (0, 5) by a scale factor of 4.

Thus, the x-coordinate of B'(x, 20) can also be obtained by multiplying the x-coordinate of B(0, 5) by 4.

i.e. x → 4×0 = 0

Thus, the rule of dilation is:

P(x, y) = P'(4x, 4y)

Step-by-step explanation:

To find out what the linear inequality of the graph:

We need to determine its slope and y-intercept. Given the following points on the graph: (1, 2) and (0, -1)

Let (x1,  y1) = (1, 2)

(x2, y2) = (0, -1)

To solve for slope, we'll use the formula:

\(m = \frac{y2 - y1}{x2 - x1}\)

\(m = \frac{y2 - y1}{x2 - x1} = \frac{-1 - 2}{0 - 1} = \frac{-3}{-1} = 3\)

Therefore, the slope = 3.

Next, we must determine the y-intercept of the line. The y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b). One of the points we used to solve for the slope reflects the coordinates of the y-intercept, (0, -1). Therefore, the y-intercept (b) =  -1.

Now that we have our slope and y-intercept, we can establish the linear equation in slope-intecept form:

y = 3x - 1.

Since the upper half of the region is already shaded, then it means that the inequality symbol must be ">". Therefore, the linear inequality of the graph is y > 3x - 1.
