You are creating an app for Alpine Ski House.
Players will move a skier between pairs of flags as the skier moves down the slope. The number of flag pairs that a user must successfully pass is three times the player's level.
Flag1 is displayed on the left and Flag2 is displayed on the right, as shown in the exhibit.
(Click the Exhibit tab.)
When the skier outside the flags, the skier will crash into an obstacle and the following actions will occur:
*
The player will lose one life.
*
An animation will play
*
A sound will play.
The player starts the game with 10 lives. If the player's life becomes 0 before the skier reaches the bottom, the skier crashes and the game ends. If the skier reaches the bottom the player gains one level.
You need to design the algorithm.
Which pseudocode should you use? To answer, select the appropriate pseudocode segments in the answer area.
NOTE: Each correct selection is worth one point.

You are decorating the gymnasium for prom. You have 100 packages of balloons. There are 18 balloons of five different colors in each package. You do not know how many balloons of each color are in a package, but you do know that each package contains some blue balloons and some white balloons and that there are at least 50 balloons of each color.
You need to initiate 50 blue balloons and 50 white balloons with helium.
A classmate has recommended the following algorithm:
You need to evaluate the result of using this algorithm.
Which three conditions will result from inflating balloons using this algorithm? (Choose three.)

You are creating an app to keep track of the performance of various basketball teams in your school's league. The app will allow users to enter the field goals attempted and field goals made for each team that played in a tournament. The app will calculate and output the field goal percentage as follows:
The field goal percentage is 25%.
You need to describe the algorithm you will use to implement this feature.
Which five actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select.

You are building a treasure hunt game.
When the player opens a treasure box, a random prize might be awarded with the following probabilities:
*
Gold Prize 2%
*
Silver Prize 5%
*
Bronze Prize 20%
You are designing an algorithm to decide the prize using the random function. The random(limit) function returns a random integer between 1 and limit, including limit. For example, if the limit is 20, the function returns a value between 1 and 20.
