1 < 15 - 2a < 7. That is the answer
Answer:
All of above
Step-by-step explanation:
Scientific notation is a mathematical expression used to represent a decimal number between 1 and 10 multiplied by ten, so you can write large numbers using less digits.
You're using the commutative property when you swap the order of factors in a multiplication:
and you use the associative property when you regroup the products of more than 2 factors in a different way:
So, you're constantly alternating between associative and commutative. Try to see which property you're using in the first step, and then keep alternating between the two!
No it's not a reasonable conclusion. Correlation does not lead to causation. If two variables are linked, then they may affect one another or there may be another set of factors involved. There isn't enough info to know for sure. The fact that r = -0.7 is fairly close to r = -1 indicates there's moderately strong negative correlation, but I don't think it's strong enough in my opinion. More research is needed.
In short, the keyword "caused" as part of the claim is what makes it unreasonable. There is no way to know that not eating vegetables leads to high blood pressure. It may be true but again, more info is needed.
