You are cutting off a piece of pie like this, where c is the length of the straight part (called the chord length) and h is the height of the piece.
There is an approximate formula for the area:
However, h is not so easy to measure, whereas the diameter d of a pie is usually well-known. Calculate the area where the diameter of the pie is 12 inches and the chord length of the segment is 10 inches. Generalize to an

- Could you help me write a python program for this: Apply the composite Gaussian Quadrature to approximate the integral (shown below) using N=10 subintervals. Calculate the absolute error using the exact integral. Repeat your calculation forN=10,20,30,40,50.

The above is wrong because.... it doesn't consider the case when adding to odd numbers m and n are different so you cannot use 2k for both it doesn't consider what m and n are for particular values in the integers it doesn't consider the case when m is even and n is oddarrow_forward
- You're hosting a game show that needs a wheel of fortune. Your task is to test if the wheel of fortune works well. To do this, spin the wheel several times and write down normalized deviation angles from the initial state so that the results range between 0 and 1. The wheel of fortune is suitable for the show if the results are evenly distributed on the interval [0, 1]. You will get the following 25 observations:0.42 0.06 0.88 0.40 0.90 0.38 0.78 0.71 0.57 0.66 0.48 0.35 0.16 0.22 0.08 0.110.29 0.79 0.75 0.82 0.30 0.23 0.01 0.41 0.09Use a suitable program language (e.g. R or Python) and a Kolmogorov–Smirnov test to check whether the wheel of fortune is suitable. Determine the p-value.arrow_forwardYou need to take a trip by car to another town that you have never visited before. Therefore, you are studying a map to determine the shortest route to your destination. Depending on which route you choose, there are five other towns (call them A, B, C, D, E) that you might pass through on the way. The map shows the mileage along each road that directly connects two towns without any intervening towns. These numbers are summarized in the following table, where a dash indicates that there is no road directly connecting these two towns without going through any other towns. Miles between Adjacent Towns Town A B C DE Destination Origin A 40 60 50 10 70 B 20 55 40 50 10 D 60 E 80 (a) Formulate this problem as a shortest-path problem by drawing a network where nodes represent towns, links represent roads, and numbers indicate the length of each link in miles. (b) Use the Dijkstra's algorithm to solve this shortest path problem.arrow_forwardYou need to take a trip by car to another town that you have never visited before.

- A fish-finder is a device used by anglers to find fish in a lake. If the fish-finder finds a fish, it will sound an alarm. It uses depth readings to determine whether to sound an alarm. For our purposes, the fish-finder will decide that a fish is swimming past if:there are four consecutive depth readings which form a strictly increasing sequence (such as 3 4 7 9) (which we will call "Fish Rising"), orthere are four consecutive depth readings which form a strictly decreasing sequence (such as 9 6 5 2) (which we will call "Fish Diving"), orthere are four consecutive depth readings which are identical (which we will call "Constant Depth").All other readings will be considered random noise or debris, which we will call "No Fish."Create a Python program called "fishfinder_firstname_lastname" that takes 1 input of string of 4 numbers separated with comma. Your program must display "Fish Rising", "Fish Diving.", "Fish At Constant Depth" or "No Fish".Example:30,10,20,20 Must display No…arrow_forwardA very known application in natural language processing is to extract information from a given text. In this lab, you will be able to extract some emotions (Sad and Happy) from a given string and calculate the score of each emotion. You will be given below the words that express sadness, anger, and happiness. For each word, you will be given weight as well, so that when you are calculating for example the score for sadness in the text (string), you can use this formula:arrow_forwardWhat will be the value of Y given: Y= A.B + (A+B) Given A=1, B= 0.arrow_forward
