The measurement of the strings decreases. (It halves each time)
Answer: 0.7071
Step-by-step explanation:
The first thing to do is to calculate the R² which is the coefficient of determination. This will be:
= 1 - SSE/SS Total
= 1 - 600/1200
= 1 - 0.5
= 0.5
Then, the correlation coefficient will be:
= ✓0.5
= 0.7071
the fraction in the image is 2 1/2
let's try each choice
1) 2/3 x 5/2 = 10/6 = 5/3
2) 5/4 x 5/2 = 25/8
3) 3/3 x 2 1/2 = 2 1/2
4) 4/5 x 5/2 = 20/10 = 2

Subtract 2n
3m = -2n + 7
Divide by 3
Solution: m = -2/3n + 7/3
