Answer:
Positive
Step-by-step explanation:
As height is increasing, shoe size is also increasing (positive slope)
Negative correlation is when one variable increases and the other decreases (negative slope)
When dividing same numbers with different exponents (they’re both 10 so this works different than if they were different numbers) you subtract the top exponent by the bottom exponent. So 15-4=11 ultimately making the solution 10^11. Hope this helps :)
