You can use spearman’s rank correlation coefficient but not sure if that’s the answer your looking for because it looks like you haven’t gave the whole question
Answer:
<u>3rd graph (on bottom left)</u>
Step-by-step explanation:
First, find the <u>zeros of the function</u>.
- f(x) = x² - x - 2
- f(x) = x² + x - 2x - 2
- f(x) = x(x + 1) - 2(x + 1)
- f(x) = (x - 2)(x + 1)
The zeros are :
- x - 2 = 0 ⇒ x = 2
- x + 1 = 0 ⇒ x = -1
Therefore, the graph of the function intersects the x-axis at :
The correct graph is <u>3rd graph (on bottom left)</u>
1. A= a²
2. Find the square root of the area to find the length of its side length.
3. √81= 9
√89= 9.43
4. For the first square, the side length is a rational number because 9 is a whole number. For the second square, the side length is irrational because the decimals do not repeat themselves.
2^(1/2) is the same thing
