Answer:

its D

Explanation:

i just took the exam it was right

In a cluster sample only convenient members of the population are chosen. The correct option is D.

In cluster sampling, a population is divided into clusters, which are smaller groups. They then choose a sample at random from these clusters.

Often employed to investigate huge populations, particularly those that are extensively geographically distributed, cluster sampling is a probability sampling technique.

Large, dispersed populations should be studied using cluster sampling because interviewing every individual would be expensive, time-consuming, and possibly impossible.

Cluster sampling enables the construction of smaller, more similar representations of the population being studied. Only practical population members are picked for a cluster sample.

Thus, the correct option is D.

By using Venn diagram method, the smallest and the largest number of students that intend to study both French and German are 21 and 49 students respectively.

Given that Larousse Language College will have 201 students in the Sixth Form next year. And between 70% and 75% of the students intend to study French. Also, between 40% and 50% of the students intend to study German.

If  all students study either French or German or both, the least number of students that will study French will be

70/100 x 201

140. 7

Which means 141 students

The least number of students that will study German will be

40/100 x 201

80.4

That means 81 students

Also, the maximum number of students that will study French will be

75/100 x 201

150.75

That is 150 students ( Because approximation can't be done twice)

And the maximum number of students that will study German will be

50/100 x 201

100 students ( Because approximation can't be done twice)

a.) The smallest number of students that intend to study both French and German can be calculated as followed

Let the smallest number be x

141 - x + x + 81 - x = 201

222 - x = 201

- x = 201 - 222

-x = - 21

x = 21

b.) The largest number of students that intend to study both French and German can be calculated as followed

Let the largest number be y

150 - y + y + 100 - y = 201

250 - y = 201

- y = 201 - 250

-y = - 49

y = 49

Therefore, The smallest and the largest number of students that intend to study both French and German are 21 and 49 students respectively.

What is environmental?

The term "environmental" refers to the surrounds on Earth. The environment is made up of both living and non-living entities. The influence of the environment on human life Plants, fisheries, animals, woods, and microorganisms are examples of biotic factors in the environment. Water, land, rocks, air, and other abiotic components are examples.

The movement of cattle and animals from one region to another, notably from the eastern to western hemispheres, had a significant environmental impact in the Americas. The animals brought west overgrazed, causing land degradation and disease transmission.

If f and h are inverses of one another, then we have

h(f(x)) = x

Differentiating both sides using the chain rule gives

h'(f(x)) • f'(x) = 1

Let f(x) = -1. Then it would follow that

h'(-1) = 1/f'(x)

for the value of x such that f(x) = -1. This result is known as the inverse function theorem.

Solve for x such that f(x) = -1 :

2x³ - 3x = -1

2x³ - 3x + 1 = 0

By inspection, x = 1 is a solution, since 2 - 3 + 1 = 0. So x - 1 is a factor of the left side; polynomial division yields a factorization of

(x - 1) (2x² + 2x - 1) = 0

and using the quadratic formula, we find three solutions,

x = 1, x = (-1 - √3)/2, x = (-1 + √3)/2

Since there's more than one solution here, this means f(x) is not one-to-one and thus has no inverse in the strict sense of the term.

We can however restrict the domain of f(x) to a subset over which it can be inverted. Using the fact that polynomials are monotonic over intervals between their extrema, we find the critical points of f(x) :

f'(x) = 6x² - 3 = 0   ⇒   x² = 1/2   ⇒   x = ± 1/√2

Check the sign of the second derivative at each critical point:

f''(x) = 12x

• f''(-1/√2) = -12/√2 < 0   ⇒   x = -1/√2 is a local maximum

• f''(1/√2) = 12/√2 > 0   ⇒   x = 1/√2 is a local minimum

Now we have a few choices of how to define the inverse of f(x).

• If we restrict the domain of f(x) to the interval (-∞, -1/√2), then f(x) = -1 when x = (-1 - √3)/2. Then by the inverse function theorem,

f((-1 - √3)/2) = -1   ⇒   h'(-1) = 1/f'((-1 - √3)/2) = (-1 + √3)/6

• If we instead restrict the domain to (-1/√2, 1/√2), then f(x) = -1 when x = (-1 + √3)/2. Then

f((-1 + √3)/2) = -1   ⇒   h'(-1) = 1/f'((-1 + √3)/2) = (-1 - √3)/6

• Otherwise, if we restrict to (1/√2, ∞), then f(x) = -1 when x = 1. Then

f(1) = -1   ⇒   h'(-1) = 1/f'(1) = 1/3

Answer:

Explanation:

The net increase in potential energy by the crate is negative 49.4 Joules. That is, ΔP.E = - 49.4 J

Given that a 40N box is pushed 5 m up a ramp. The angle of the ramp is 37° above the horizontal.

We can find the height h of the ramp with the equation below;

h = 5sin 37

h = 3.009 m

Mass of the box = 40/9.8 = 4.082 kg

The maximum energy attained = mgh

Maximum Energy = 4.082 x 9.8 x 3.009

E = 120.36 J

The maximum K.E = Maximum P.E

1/2m[tex]U^{2}[/tex] = 120.36

m[tex]U^{2}[/tex] = 240.72

[tex]U^{2}[/tex] = 240.72 / 4.082

[tex]U^{2}[/tex] = 58.97

U = [tex]\sqrt{58.97}[/tex]

U = 7.7 m/s

We can find the acceleration by using third equation of motion

[tex]V^{2}[/tex] = [tex]U^{2}[/tex] - 2aS

Since the box is going to rest, V = 0, and acceleration will be negative

0 = 7.7^2 - 2 x a x 5

10a = 59.29

a = 59.29/10

a = 5.93 m/[tex]s^{2}[/tex]s^2

The applied force F = ma

F = 4.082 x 5.93

F = 24.2 N

Given also that the applied force is parallel to the ramp and opposed by a frictional force of 10.0 N. The net increase in potential energy by the crate will be

ΔP.E = Net work done

ΔP.E = Net force x distance

ΔP.E = (24.2 - 10 - 40sin37) x 5

ΔP.E = - 9.87 x 5

ΔP.E = - 49.4 J

Therefore, The net increase in potential energy by the crate is negative 49.4 Joules.

Solution

To determine the angle of the velocity, we use the following equation.

Tan θ = Vertical velocity ÷ Horizontal velocity

As the particle moves from its initial position to its final position, its vertical velocity decreases at the rate of 9.8 m/s each second. During this time its horizontal velocity is constant. To determine the time when the angle is 45˚, we need to determine the object’s vertical velocity at this angle. Let’s determine the vertical and horizontal components of its initial velocity.

Vertical = 50 × sin 60˚, Horizontal = 50 × cos 60˚ = 25 m/s

Since horizontal velocity is constant, let’s put 25 m/s and 45˚ into the tangent equation.

Tan 45 = Vertical velocity ÷ 25

Vertical velocity = 25 m/s

To determine the time for the vertical velocity to decrease from its initial value to 25 m/s, use the following equation.

vf = vi – a × t

a = 9.8

25 = 50 × sin 60˚ – 9.8 × t

t = (25 – 50 × sin 60˚) ÷ -9.8

This is approximately 1.83 seconds.

f(x) = d/ dx (2.5x1.3)

f(x) =2.5×d/dx(1.3*)

f(x) =5xIn 13/10 x 13*/2×10*

So the answer is

f(x)=5•IN13/10•13*/2•10*

That's the correct answer I see in my book

f(x)=5•IN13/10•13*/2•10* is the percent rate of increase for the exponential function.

The formula for an exponential function is f (x) = ax, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.

Y=abx y = a b x is the fundamental exponential function equation, where a denotes the y-intercept and b the growth factor.

When b > 0 and b 1, an exponential function has the form f(x) = bx. The base is b, and the exponent is x, just like in any exponential expression. The development of bacteria is an illustration of an exponential function. Some germs multiply by two per hour.

f(x) = d/ dx (2.5x1.3)

f(x) =2.5×d/dx(1.3*)

Explanation:

GPS data is extensively used in the study of certain animals to understand their movements, behaviors, and habitats.

Researchers attach GPS tracking devices to animals such as migratory birds, marine mammals, and large terrestrial mammals. These devices record the animal's location at regular intervals, allowing scientists to track their movements over time.

By analyzing GPS data, researchers can identify migration routes, feeding areas, and breeding grounds of the studied species.

This information is vital for conservation efforts, as it helps identify critical habitats and migration corridors, assess the impact of human activities, and inform effective management strategies to protect these animals and their ecosystems.
