PHP* Create a function that takes a list of numbers and returns the second largest number. Examples secondLargest([10, 40, 30, 20, 50]) ➞ 40 secondLargest([25, 143, 89, 13, 105]) ➞ 105 secondLargest([54, 23, 11, 17, 10]) ➞ 23 Notes ● There will be at least two numbers in the array.

4. Array code Fill in the method below to have it create and fill in an array of 4 doubles. The first ele- ment should be set to the average of the first quarter of the array passed to data, the second element should be set to the average of the second quarter of the array, and so on. If input data is [1, 2, 3, 4, 5, 6, 7, 8] result should be [1.5, 3.5, 5.5, 7.5] public static double[] quartileAverages(int [] data) {

Poker A poker hand can be stored in a two-dimensional array. The statement int hand[4][13]; declares an array with 52 elements, where the first subscript ranges over the four suits and the second subscript ranges over the thirteen ranks. A poker hand is specified by placing 1's in the elements corresponding to the cards in the hand. See Figure 1. Figure 1 A 2 3 4 5 6 7 8 9 10 J Q K Club 1 Diamond Heart ♥ 1 Spade a 0|0 1 1, 1,

# Declare a named constant for array size here. MAX_AVERAGES = 8 # Declare array here. # Write a loop to get batting averages from user and assign to array. averageString = input("Enter a batting average: ") battingAverage = float(averageString) # Assign value to array. # Assign the first element in the array to be the minimum and the maximum. minAverage = averages[0] maxAverage = averages[0] # Start out your total with the value of the first element in the array. total = averages[0] # Write a loop here to access array values starting with averages[1] # Within the loop test for minimum and maximum batting averages. # Also accumulate a total of all batting averages. # Calculate the average of the 8 batting averages. # Print the batting averages stored in the averages array. # Print the maximum batting average, minimum batting average, and average batting average. This is on mindtap pyton what needs to be fix

Description Create an application that maintains an array of your home inventory and displays the contents of the array in a list box. For this assignment, we will be using an array. In later chapters, we will modify this application to use a database or an external text file. The application should look like: g My Home Inventory Home Inventory Item Description Ist Homelnventory Serial Number Cost ADD DELETE REFRESH BYE Detailed Instructions 1. Define arrays for Item Description, Serial Number, and Cost after the Public Form Q and before any click of page load events. 2. In the Page Load Event, populate the Home Inventory List Box with the data from the arrays using the format: "ItemDecription (SerialNumber, Cost)". 3. If the ADD button is clicked, add the Item Description, Serial Number, and Cost to the Home Inventory List Box and to the appropriate arrays. 4. If the DELETE button is clicked, remove the item from the Home Inventory List Box and corresponding arrays. 5. If the REFRESH…

Create Array of Random Dates In this task you are required to write a function that will generate a column array (a variable called dates) containing N random dates. N is an integer (whole number) entered by the user and will indicate to the function how many random dates the user requires. The dates array will be structured as follows: • The array shall have two columns; column 1 will contain numbers indicating the day of each month (1-31) and column 2 will contain numbers indicating the month (Jan 1, Feb=2, Mar = 3.... Dec = 12). . Each day must be randomly generated (using the randi() function) taking into account the maximum number of days in each month (i.e. Jan, Mar, May, Jul, Aug. Oct and Dec have 31 days, Apr. Jun, Sep and Nov have 30 days and Feb will have 28 days). You must use an if-elseif-else statement to decide this. • We are assuming no leap years (e. February can only have days between 1-28). For example, the output from calling the function: output = dategen (3) could…

python: numpy def purchases(transactions):    """    QUESTION 7    - A high-end store is trying to evaluate the total amount that customer's spend per transaction. They      want customers to spend anywhere between $130 and $150 on average.    - You need to determine whether the average number spent on each transaction per month is above, between, or      below the desired amount.    - Transactions is a numpy array containing a date, total amount earned each month, and total      number of transactions each month.    - Above: month's average amount spent per transaction > 150    - Within Range: 150 >= month's average amount spent per transaction >= 130    - Below: month's average amount spent per transaction < 130    - Return a numpy array with "Above", "Within Range" and "Below" for the average amount spent per transaction per month    - THIS MUST BE DONE IN ONE LINE    HINT: use np.where() and convert the type of each column to float     Args:        transactions…

Matrix Multiplication• Write a multiplication function that accepts two 2D numpy arrays,and returns the product of the two. This function should test that thearrays are compatible (recall that the number of columns in the firstmatrix must equal the number of rows in the second matrix). Thisfunction should test the array sizes before attempting themultiplication. If the arrays are not compatible, the function shouldreturn -1.   solve in python

part a- 2point) for 3 students find the average of a student by asking him how many grades do you have. The answer to this question, determine the size of the array(list of grades) and then ask the user to enter grades(the number of the grades is equal to the size of the array) then calculate the average for each student. Hence, you will calculate 3 averages. to calculate the average, use the array accumulator. Also when you get each grade validate it. validation for grade means that you check whether a grade is between 0 and 100. if the grade is negative or a grade is more than 100 then it is not valid and you have to ask the user to enter a grade again. Part b- 1 point) Find the maximum and minimum grades for each student. Part c- 1 point) Print the sorted list of the grades for each student. example: if grades user entered are: 60 78 98 23 45 then sorted list is:23 45 60 78 98 (Array not vector)
