The best statement that describes the associations between variable X and variable Y is the first option, "no association."
Answer:
B: 2x + 2 + x
Step-by-step explanation:
I just had this question and got it right
Kendall and Sophia swam (2n - 12) laps together
<em><u>Solution:</u></em>
Given that, Kendall Swam (n) laps in the pool
To find: Number of laps swam together
From given statement,
Number of laps by Kendall = n
Also, Sophia swam 12 less than Kendall
Therefore, number of laps swam by Sophia is 12 less than the number of laps by Kendall
Number of laps by Sophia = Number of laps by Kendall - 12
Number of laps by Sophia = n - 12
<em><u>How many laps did they swim altogether ?</u></em>
Number of laps swam together = Number of laps by Kendall + Number of laps by Sophia
Number of laps swam together = n + n - 12 = 2n - 12
Thus they swam (2n - 12) laps together
