Studdy Solution
STEP 1
What is this asking?
Which quantity depends on the other: the number of innings played or the number of outs made?
Watch out!
Don't get tricked by the order the information is presented!
Think carefully about which quantity *causes* the other to change.
STEP 2
1. Define the relationship
2. Identify the dependent variable
STEP 3
Alright, awesome students, let's break this down!
We know that for *every* inning a baseball team plays, they get outs.
This tells us how the number of outs relates to the number of innings.
STEP 4
Let's write this relationship as a super cool formula!
If is the number of innings and is the total number of outs, then we can say:
This equation tells us that the **total number of outs**, , is **three times** the **number of innings** played, .
STEP 5
Now, the big question: which is the *dependent* variable?
The dependent variable is the one that *changes* based on the other.
Think of it like this: the number of outs *depends* on how many innings are played.
STEP 6
Let's imagine Silvio's team plays **one** inning ().
How many outs do they get?
Using our awesome formula, . **Three** outs!
STEP 7
Now, let's say they play **two** innings ().
Now, . **Six** outs!
See? The number of outs, , *depends* on the number of innings, .
STEP 8
In Silvio's case, the team played innings, leading to outs.
Again, the number of outs *depends* on the number of innings played.
STEP 9
The dependent variable is , the **total number of outs**, because it depends on the number of innings played, .
