Use the if statement to represent the following segment function f(x), the following program is incorrect A
f(x) = (2x+ 1) x≥1
~~~~~~
= 3x/(x-1) x< 1
A. if(x>=1):f=2 * x+1
f=3 * x/(x- 1)
B. if (x>=1): f=2 * x+1
if (x<1): f=3 * x/(x-1)
C. f = 2 * x+ 1
if (x<1): f=3 * x/(x-1)
D. if (x<1): f=3 * x/(x-1)
else: f= 2 * x+1
Just find a number to substitute
The following if statement counts the number of people who meet the conditions of "gender is male, rank is professor, age (age) is less than 40 years old". The correct statement is B
A. if (gender == “Male” orage<40 and rank == “Professor”): n+=1
B. if (gender == “male” and age<40 and rank == “professor”): n+=1
C. if (gender == “male” and age<40 or rank == “professor”); n+=1
D. if (gender == “male” or age<40 or rank == “professor”): n+=1
The following program segment finds the large number among the two numbers x and y. DIt's incorrect
A. maxMum= x if x > y else y
= (x，y)
(x>y): maxNum = x
else: maxNum = y
(y>=x): maxNum=y
maxNum=x
The following if statement counts the number of boys with excellent scores and boys who fail the score. The correct statement is C
A. (gender= = "male" and score<60 or score>=90): n+=1
B. if(gender == “male” and score<60 and score>=90): n+=1
C. if (gender =="male" and (score<60 or score>=90)): n+=1
D. if (gender = = "male" or score<60 or score>=90): n+=1
Use the if statement to represent the following segmented function:
y = x^2-2x+3 x<1
= sqrt(x-1) x≥1
The following program segment is incorrect B
A. if(x<1):y=x * x- 2 * x + 3
else:y=(x-1)
B. if(x≤1):y = x * x- 2 * x + 3
y = math. sqrt(x-1)
C. y = x * x - 2 * x + 3
if(x>= 1):y= (x-1)
D. if(x<1): y = x * x - 2 * x + 3
if(x>=1):y = math. sqrt(x-1)
