A programmer wants to determine whether a score is within 10 points of a given target. For example, if the target is 50, then the scores 40, 44, 50, 58, and 60 are all within 10 points of the target, while 38 and 61 are not. Which of the following Boolean expressions will evaluate to true if and only if score is within 10 points of target ? A (score s target + 10) AND (target + 10 s score) B (target + 10 s score) AND (ScOre s target - 10) (score s target 10) AND (SCOre s target + 10) (target - 10 s score) AND (SCOre s target + 10)

In python, a) In the Hi-Lo game, the player begins with a score of 1000. The player is prompted for the number of points to risk and a second prompt asks the player to choose either High or Low. The player’s choice of either High or Low is compared to a random number between 1 and 13, inclusive. If the number is between 1 and 6 inclusive, then it is considered “low”. A number between 8 and 13 inclusive is “high”. The number 7 is neither high nor low, and the player loses the points at risk. If the player had guessed correctly, the points at risk are doubled and added to the total points. For a wrong choice, the player loses the points at risk. Create a HiLo application based on this specification. Application output should look similar to b) Modify the application to allow the player to continue until there are 0 points left. At the end of the game, display the number of guesses the user took before running out of points.
Write a program that reads student scores, gets the best score, andthen assigns grades based on the following scheme:Grade is A if score is ≥ best -5Grade is B if score is ≥best -10;Grade is C if score is ≥best -15;Grade is D if score is ≥best -20;Grade is F otherwise.The program prompts the user to enter the total number of students, and thenprompts the user to enter all of the scores, and concludes by displaying the grades.Here is a sample run: Enter the number of students: 4 ↵EnterEnter 4 scores: 40 55 70 58 ↵EnterStudent 0 score is 40 and grade is FStudent 1 score is 55 and grade is CStudent 2 score is 70 and grade is AStudent 3 score is 58 and grade is C

Scenario As you surely know, due to some astronomical reasons, years may be leap or common. The former are 366 days long, while the latter are 365 days long. Since the introduction of the Gregorian calendar (in 1582), the following rule is used to determine the kind of year: if the year number isn't divisible by four, it's a common year, otherwise, if the year number isn't divisible by 100, it's a leap year. otherwise, if the year number isn't divisible by 400, it's a common year. otherwise, it's a leap year. none of the above year int(input("enter the year")) if (year%4 1-0) and (year%400 -0) or (year % 1000): print (year is common year") else: print(year, is leap year") year= int(input ("enter the year")) if (years !-0) or (year480 1-0) and (year % 1001-0): print(year is common year") else: print(year, "is leap year") D year= int(input("enter the year"))
