Expert Solution & Answer
Chapter 8, Problem 5RQ
Program Description Answer
The following block of code is used to correctly calculate the average value stored in the array:
Do While intSub < 4
intTotal = intTotal + intNums(intSub)
intSub = intSub + 1
Loop
dblAvg = intTotal/intSub
Hence, the correct answer is option “B”.

The intNums array is declared as follows: Dim intNums() As Integer = {10, 5, 7, 2}. Which of the following blocks of code correctly calculates the average value stored in the array? The intTotal, intSub, and dblAvg variables contain the number 0 before the loop is processed. a. Do While intSub < 4 intNums(intSub) = intTotal + intTotal intSub += 1 Loop dblAvg = intTotal / intSub b. Do While intSub < 4 intTotal += intNums(intSub) intSub = intSub + 1 Loop dblAvg = intTotal / intSub c. Do While intSub < 4 intTotal += intNums(intSub) intSub += 1 Loop dblAvg = intTotal / intSub – 1 d.

- You are working for a company that developed a new drug which increases HDL cholesterol (the good cholesterol). A variety of dosages were given to participants during a trial, and the increases of HDL cholesterol were measured. This information is summarized in the following plot: Dosage vs Increase 80 70 60 50 40 30 20 10 15 x - dosage in mg 10 20 25 30 Each point (x, y) in the above plot represents a participant who was given a dosage of æ mg and had an HDL increase of y mg/dL. This information is stored in the 2d numpy array trial_data. The r-values are stored in the first row of trial_data (i.e. trial_data[@]) and the y-values are stored in the second row of trial_data (i.e. trial_data[1]). You are now working with a physician to determine the right dosage for one of her patients. 1) In order to help your client, first find a vector B = [B1] such that y(x) = B1 + Bza is the least squares line [B2] for the above data.

The application should use a two-dimensional int array to simulate the game board in memory. When the user clicks the New Game button, the application should step through the array, storing a random number in the range of 0 through 1 in each element. The number 0 represents the letter O, and the number 1 represents the letter X. The form should then be updated to display the game board. The application should display a message indicating whether player X won, player Y won, or the game was a tie.arrow_forwardHands-On Activities Hands-On Activity 10-1 Write a pseudocode program that creates an array, prompts the user to enter five cities, and displays the array's contents.
