Nested conditionals
This program uses a nested conditional to assign the variable mystery to a value: IF (x > y) { mystery ← x - y } ELSE { IF (x = y) { mystery ← y / x } ELSE { mystery ← x * y } } If we set x to 4 and y to 8, what value will the mystery variable store after running this code? Choose 1 answer:
32
This program uses a nested conditional to assign the variable mystery to a value: IF (x > y) { mystery ← x - y } ELSE { IF (x < y) { mystery ← y / x } ELSE { mystery ← x + y } } If we set x to 32 and y to 8, what value will the mystery variable store after running this code?
24
This program uses a nested conditional to assign the variable mystery to a value: IF (x > y) { mystery ← x - y } ELSE { IF (x < y) { mystery ← y / x } ELSE { mystery ← x + y } } If we set x to 8 and y to 24, what value will the mystery variable store after running this code?

A software engineer for a movie theater is writing a program to calculate ticket prices based on customer ages. The program needs to implement this pricing chart: Ticket typePriceGeneral Admission$16Senior (Ages 65+)$12Child (Ages 2-12)$8Infants (Ages 0-1)Free The code segment below uses nested conditionals to assign the price variable to the appropriate value, but its conditions are missing operators. price ← 0 IF (age <?> 64) { price ← 12 } ELSE { IF (age <?> 12) { price ← 16 } ELSE { IF (age <?> 1) { price ← 8 } } } Which operator could replace <?> so that the code snippet works as expected?

A programmer for a music company is developing a program to determine the highest level of certification for an album. The program needs to follow this table of thresholds for each certification level: Minimum albums sold Certification 500,000 gold 1,000,000 platinum 10,000,000 diamond The code segment below uses nested conditionals to assign the certification variable to the appropriate value, but its conditions are missing operators. certification ← "none" IF (albumsSold <?> 10000000) { certification ← "diamond" } ELSE { IF (albumsSold <?> 1000000) { certification ← "platinum" } ELSE { IF (albumsSold <?> 500000) { certification ← "gold" } } } Which operator could replace <?> so that the code snippet works as expected?
