false it starts from 1 and continues
Answer: (0, 1), (-1, -3)
Given two equation's:
- y = 2x² + 6x + 1
- y = −4x² + 1
<u>Solve them simultaneously</u>:
(a) When x = 0, y = −4(0)² + 1 = 1
(b) When x = -1, y = -4(-1)² + 1 = -3
Solution: (x, y) → (0, 1), (-1, -3)
The middle 50% of the data falls between 13 and 31.
The middle 50% of any data set falls within the box of a box-and-whisker plot. This particular box extends from 13 to 31, so this is the middle 50% of the data.
