6Lucas has 51 points, Ava has 57 points, and Zoe has 45 points. Lucas gives 7 points to Zoe. After that, how many more points does Ava have than Zoe?
Show answer & explanation
Answer: 5
Step 1: Lucas's total after giving 7 points to Zoe (51 − 7) = 44 Step 2: Zoe's total after receiving 7 points from Lucas (45 + 7) = 52 Step 3: difference between Ava's total and Zoe's new total (57 − 52) = 5 So the answer is 5 — how many more points Ava has than Zoe.
7Carlos has 57 points, Lucas has 64 points, and Mia has 48 points. Carlos gives 10 points to Mia. After that, how many more points does Lucas have than Mia?
Show answer & explanation
Answer: 6
Step 1: Carlos's total after giving 10 points to Mia (57 − 10) = 47 Step 2: Mia's total after receiving 10 points from Carlos (48 + 10) = 58 Step 3: difference between Lucas's total and Mia's new total (64 − 58) = 6 So the answer is 6 — how many more points Lucas has than Mia.
8Solve: 3x + 5 = 26

9A data set is: 8, 9, 10, 11, 62. Which measure of center best describes a 'typical' value in this data set, and why?
Show answer & explanation
Answer: The median, because the outlier 62 skews the mean far above most of the data
The value 62 is a significant outlier. It raises the mean well above the other four values, so the median (10) better represents the typical value.
