Answer: 2.6
Step-by-step explanation:
Step 1: Calculate the mean of Shade's plant heights.
= 7+12+12+8+9+8+8+8/8
= 72/8
=9
Step 2: Calculate the range of Shade's plant heights. Range is highest minus lowest number. This will be:
12 - 7 = 5
Step 3: Calculate the mean of Sun plant heights.
19+24+20+23+24+23+23+20/8
= 176/8
= 22
Step 4: Find the range of Sun plants height.
= 24 - 19 = 5
Step 5: Find the difference of means
= 22 - 9
= 13
Step 6: Divide the difference of means by the range.
= 13 ÷ 5
= 2.6
Answer:

12x=84
x=12
Answer:
See screenshot for graph and points - This is <em>not</em> a function because it fails the vertical line test.
Step-by-step explanation:
The vertical line test means that if you can draw a vertical line anywhere on the graph and it hits more than one part of the graph, then it isn't a function.
