what is this?

Answer:

yes it is correct

Step-by-step explanation:

We multiply the probabilities together: (1/4) * (1/5) * (1/2) = 1/40. Therefore, the probability that a randomly chosen person orders a Cobb salad, juice, and a lemon pie is 1 out of 40, or 1/40. The probability that a randomly chosen person orders a Cobb salad, juice, and a lemon pie can be found by multiplying the probabilities of each event happening individually.

Firstly, the probability of a guest ordering a Cobb salad is 1 out of 4 main course options or 1/4. Secondly, the probability of a guest choosing juice is 1 out of 5 drink options or 1/5.  Lastly, the probability of a guest selecting a lemon pie for dessert is 1 out of 2 dessert options or 1/2. To find the probability of all three events happening together, we multiply the individual probabilities: 1/4 x 1/5 x 1/2 = 1/40.Therefore, the probability of a randomly chosen person ordering a Cobb salad, juice, and a lemon pie is 1/40.

The probability of a guest ordering a Cobb salad is 1/4, the probability of choosing juice is 1/5, and the probability of selecting a lemon pie for dessert is 1/2. To find the probability of all three events happening together, we multiply the individual probabilities. Thus, the probability that a randomly chosen person orders a Cobb salad, juice, and a lemon pie is 1/40.

To prove this identity, we start with Fermat's Little Theorem, which states that if p is a prime number and a is any integer coprime to p, then a^(p-1) ≡ 1 (mod p).

Using this theorem, we can rewrite the given identity as a^(p-1) * a(p-2) ≡ 1 (mod p^2).

Next, we can multiply both sides by a to get a^(p-1) * a(p-1) ≡ a (mod p^2).

Since a and p are coprime, we can use Euler's Totient Theorem, which states that a^φ(p) ≡ 1 (mod p) where φ(p) is the Euler totient function. Since p is prime, φ(p) = p-1, so a^(p-1) ≡ 1 (mod p).

Using this result, we can rewrite our identity as a^(p-1) * a(p-1) * a^-1 ≡ a^(p-1) ≡ 1 (mod p), which implies that a^(p-1) ≡ 1 (mod p^2).

Therefore, we have proven the identity a p(p−1) ≡ 1 (mod p 2 ), where a is coprime to p, and p is prime.

The possible values of a and b are a = 0 and b ≠ 0.The DIFFERENTIATION equation y = e^ɑt + b(x+1)^3 satisfies the conditions dy/dx = 0 and d^2y/dx = 0 when a = 0 and b ≠ 0

Given the equation y = e^ɑt + b(x+1)^3, we need to find the possible values of a and b when x = 0, and both the first and second derivatives of y with respect to x, dy/dx and d^2y/dx, are zero.

First, let's find dy/dx:

dy/dx = 0 + 3b(x+1)^2 = 3b(x+1)^2

Next, let's find d^2y/dx^2:

d^2y/dx^2 = 6b(x+1)

Now, substituting x = 0 into both equations:

dy/dx = 3b(0+1)^2 = 3b

d^2y/dx^2 = 6b(0+1) = 6b

Since dy/dx = 0, we have 3b = 0, which implies b = 0.

Therefore, the possible values of a and b are a = 0 and b ≠ 0.

The equation y = e^ɑt + b(x+1)^3 satisfies the conditions dy/dx = 0 and d^2y/dx = 0 when a = 0 and b ≠ 0.

Step-by-step explanation:

This means that 9% of the notebook is used in science.

This means that 91% of the notebook pages is remaining.

Answer:

18.87 square cm.

Step-by-step explanation:

The area of the rectangle will be (4 + 4) * 4, since the length of the rectangle would be the diameter of the circle, and the width of the rectangle would be the radius. (4 + 4) * 4 = 8 * 4 = 32 square cm.

Then, we can calculate the area of the semicircle. The area of a circle is pi * r^2, so the area of a semicircle will be half of that. pi * (4^2) / 2 = pi * 16 / 2 = 8pi. 8 * 3.14159265 = 25.1327412 square cm.

The shaded area of the middle of the shape will then be 32 - 25.1327412 = 6.8672588 square cm.

The two triangles will have the same area. Their bases will be 14 minus the diameter of the circle, then divide that by 2 to get each separate base. 14 - 8 = 6 / 2 = 3. The heights of the triangles will be the radius of the circle, or 4 cm.

1/2 * 3 * 4 = 1/2 * 12 = 12/2 = 6. That is the area of one triangle, so the area of both triangles would be 6 * 2 = 12 square cm.

6.8672588 + 12 = 18.8672588, or 18.87 square cm.

Answer:

(44 - 8(pi)) cm^2    Exact area

18,9 cm^2    Approximate area

Step-by-step explanation:

The shaded area is the area of the trapezoid minus the area of the semicircle.

area of trapezoid = (b1 + b2)h/2

area of semicircle = (pi)(r^2)/2

The triangles at both sides are right triangles. Each of the horizontal legs has length (14 cm - 8 cm)/2 = 3 cm. Each of the vertical legs is congruent to the radius of the semicircle.

b1 = lower base = 14 cm

b2 = upper base = 14 cm - 3 cm - 3 cm = 8 cm

shaded area = (b1 + b2)h/2 - (pi)(r^2)/2

= (14 cm + 8 cm)(4 cm)/2 - (pi)(4 cm)^2 / 2

= 44 cm^2 - 8(pi) cm^2

= (44 - 8(pi)) cm^2    Exact area

= 18.9 cm^2    Approximate area

The equation of a circle can be written as\((x - h)^2 + (y - k)^2 = r^2,\)where (h, k) is the center of the circle and r is the radius.

Circle's basic equation is represented by:

\((x-h)^2 + (y-k)^2 = r^2\)

where the radius is r and the circle's center's coordinates are (h,k).

Let's first consider what a circle is before determining its equation. A circle is a collection of all points in a plane that is uniformly distanced from a fixed point. The fixed point is referred to as the circle's center. The radius of a circle is the separation between the center and any point along its circumference. In this post, we'll go over what a circle equation in standard form is and how to calculate a circle's equation when the origin serves as its center.
Therefore, the equation of a circle whose center is (4, -5) and which has a radius of 3 is:

\((x - 4)^2 + (y + 5)^2 = 3^2\)
Simplifying and expanding the equation gives:

\((x - 4)^2 + (y + 5)^2 = 9\)

And that is the equation of the circle.

The activity ratio in the value stream measures the efficiency of the production process by evaluating the ratio of value-added activities to non-value-added activities.

The activity ratio is a performance metric used in value stream mapping, which is a lean management tool for analyzing and improving the flow of materials and information in a production process.

It focuses on distinguishing value-added activities, which directly contribute to meeting customer requirements, from non-value-added activities, which do not add value but consume resources and time.

By calculating the activity ratio, organizations can assess the proportion of time and resources spent on value-added activities versus non-value-added activities.

A higher activity ratio indicates that a greater portion of resources is dedicated to value-added activities, indicating improved efficiency and reduced waste.

Conversely, a lower activity ratio suggests a higher proportion of resources being utilized for non-value-added activities, indicating potential areas for improvement and waste reduction.

The activity ratio serves as a valuable diagnostic tool for organizations to identify process inefficiencies, bottlenecks, and areas for improvement. By analyzing the activity ratio, organizations can streamline their processes, eliminate waste, and optimize resource allocation to enhance overall productivity and customer value.

The required ordered pair represents the center of the new circle after the transformation is (-x,y). Option A is correct.

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them.

Here,
If a circle is reflected across the y-axis, its center, which was originally located at (x, y), will move to a new location that is the same distance from the y-axis but on the opposite side. Since the y-coordinate does not change during a reflection across the y-axis, the y-coordinate of the new center will remain the same as the original, which is y.

However, the x-coordinate will be negated, since the reflection across the y-axis involves flipping points to the opposite side of the y-axis. Therefore, the center of the new circle will have the coordinates (-x, y).

So the answer is A) (-x, y).

Answer: Option 2

The line starts at an x of -4, so the domain is from -4 to infinity since the arrow goes off the graph, meaning it keeps going. The line starts on a y of 2, and the line continues up with the arrow pointing slightly up, so the range is from 2 to infinity.

The domain is from left to right, and the range is down to up

Answer:

2.  {x | x ≥ −4}; {y | y ≥ 2}

Step-by-step explanation:

Let's try to determine the domain first. Look at the x values. The function begins at -4, so our possible domain values also begin at -4, and the values continue positively after -4.

Therefore, our domain is: Domain: {x ≥ -4}.

Or, we could assign our domain using interval notation: [-4,infinity).

Our range, or y values, begin at 2 and continue positively after 2.

Therefore, our range is: Range: {y ≥ 2}.

Again, we could use interval notation to assign our range: [2,infinity)

Therefore, the answer would be
