The histogram with the narrow peak would be expected to contain more consistent numbers.

This is because the width of a histogram reflects the variability of the data that it represents. A histogram with a wide spread indicates that the data values are spread out and vary greatly, while a histogram with a narrow peak indicates that the data values are relatively consistent and cluster close together.

In a histogram with a widespread, the difference between the highest and lowest data values is large, indicating that the values are inconsistent and vary widely. On the other hand, in a histogram with a narrow peak, the difference between the highest and lowest data values is small, indicating that the values are more consistent and cluster closely together.

Answer:

41.1 cm

Step-by-step explanation:

1) Find the perimeter of the visible rectangle...

1) Find the perimeter of semicircles

We can put the semicircles together to make a whole circle so instead of finding the perimeter of both semicircles separately we can find the perimeter of a whole circle with radius 4.

3) Add the results

Have a lovely day :)

Total Perimeter of the figure is 41.13274 cm

Given that,

Length of a side = 4 cm

Now,

There are two semi circles being formed in the figure. If we add both it will form a circle.

The perimeter of the circle = Circumference of the circle

Circumference = 2 π r                         ( r  = 4 cm i.e. a side)

                         = 2 π * 4

                         = 8 π cm

and the four sides of the figure that are left, form a square,

so, the perimeter of the square = 4 * side

                                                     = 4 * 4 = 16 cm

Total Perimeter = 8π +16

                          = 41.13274 cm

Therefore, Total Perimeter of the figure is 41.13274 cm

The value of the trigonometric functions given that the point (-112, -15) is on the terminal side of an angle, θ is sin(θ)= y/r = -15/ 113 cos(θ)= x/r = -112/ 113 tan(θ)= y/x = -15/ -112 csc(θ)= r/y = 113/ -15 sec(θ)= r/x = 113/ -112.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

The terminal points are given as follows:

x = -112 and y = -15

Using the Pythagorean theorem we have:

x^2 + y^2 = r^2

(-112)^2 + (-15)^2 = r^2

12544 + 225 = r^2

r = 113

Now, the trigonometric functions is given as:

sin(θ)= y/r = -15/ 113

cos(θ)= x/r = -112/ 113

tan(θ)= y/x = -15/ -112

csc(θ)= r/y = 113/ -15

sec(θ)= r/x = 113/ -112

Dinah can calculate the total amount she will pay, including tip, by adding the bill amount to 18% of the bill amount. Mathematically, this can be represented as 1.18b.

As per the data given in the question,

Percentage tip was given to waiter= 18%.

Let the total amount spent on food = b

So, the amount given to the waiter will be: 18% of b

So, for finding the amount we will first remove the percentage sign, for removing the percentage sign we will divide the given number by 100.

Thus, the amount given to waiter will be

=(18/100)*b

= 18b/100

=0.18b

So, the total amount spent will be equal to b+0.18b = 1.18b

The relative frequency of responders who chose the vegetarian meal is 0.5, or 50%.

The concept used in this problem is relative frequency, which is a measure of the number of times an event occurs in a data set, expressed as a fraction of the total number of events.

The relative frequency is a useful tool for summarizing and understanding the distribution of data, and provides a way to compare the relative frequencies of different events in a data set.

To create a relative frequency distribution in Excel, you would first create a table with the four meal options (chicken, fish, steak, and vegetarian) and count the number of times each option was selected. The relative frequency is calculated as the count of each meal option divided by the total number of responses (20 in this case).

Here is the frequency distribution as :

Meal Option → Frequency → Relative Frequency

Chicken → 6 → 0.3 (6/20)

Fish → 2 → 0.1 (2/20)

Steak → 2→ 0.1 (2/20)

Vegetarian →  10 → 0.5 (10/20)

Blinding refers to the nondisclosure of the treatment an experimental unit is receiving in a controlled experiment.

Blinding is a technique used in experimental design to reduce bias and improve the validity of results. It refers to the practice of not revealing to the experimental units (e.g., participants, animals) or the experimenters which treatment they are receiving in a controlled experiment.

Blinding is used to eliminate potential sources of bias that might influence the results of the experiment. For example, if the participants are aware of the treatment they are receiving, they might behave differently and affect the results. Similarly, experimenters might unconsciously treat participants differently based on their knowledge of the treatment, which could also affect the results.

The algorithm design technique best describes Dijkstra's SSSP algorithm is (c) Greedy.

Dijkstra's Single Source Shortest Path (SSSP) algorithm is considered a greedy algorithm because it makes locally optimal choices at each step in order to find the globally optimal solution. The algorithm starts from the source vertex and maintains a priority queue of vertices, where the priority of a vertex is determined by the length of the shortest path from the source to that vertex.

At each step, the algorithm chooses the vertex with the smallest priority, updates the distances of its neighbors, and adds them to the priority queue. This process continues until all vertices have been processed or a target vertex has been found. The algorithm always makes the choice that appears to be the best at the moment, with the goal of finding the shortest path from the source to all vertices.

The general solution to the differential equation y'' - 2y' + y = 8e^-t is given by: y = c1e^(4t) + c2e^(-2t) + (4t + 1)e^-t.

The general solution to the  differential equation y'' - 2y' + y = 8e^-t can be found using the method of characteristic equations.

The characteristic equation is obtained by substituting y = e^rt into the differential equation: r^2e^rt - 2re^rt + e^rt = 8e^-t

Expanding the left side:

r^2e^rt - 2re^rt + e^rt = 8e^-t

r^2e^rt - 2re^rt + (1-8)e^rt = 0

Solving for the characteristic equation:

(r-4)(r+2) = 0

The characteristic equation has two roots, r = 4 and r = -2. These roots correspond to the two linearly independent solutions of the differential equation:

y = c1e^(4t) + c2e^(-2t)

where c1 and c2 are arbitrary constants.

Therefore, The general solution to the differential equation y'' - 2y' + y = 8e^-t is given by:

y = c1e^(4t) + c2e^(-2t) + (4t + 1)e^-t

where c1 and c2 are arbitrary constants determined by initial conditions or boundary conditions.
