Answer:

B) False because r is closer to 1

Step-by-step explanation:

A perfect negative correlation is seen as r=-1, since the answer r=0.997 is positive and very close to 1, this is almost a perfect POSITIVE correlation. Since the question asks about a negative correlation it is false, and the reasoning is because it is closer to 1 than 0. If it was closer to 0 than it would be a "low" correlation but not negative. The answer is B.

valentina_108 [34]
Well I'm not sure what the answer would be since I'm not that smart but I did get the answer of 90, I did this by dividing 72 by 80 which equals .9 and I multiplied that by 100 and got 90.

Would you rather discover alien life or an animal that was thought to be extinct?

The reason i say this is because i don't really want to run into something that i don't know much about. I do know quite a bit about extinct animals more than i do aliens. So, that's my reasoning.

after elsa backed muffins, her brother ate 4 of them, he ate 2/5 of all the muffins, how many muffins did elsa bake?
kondor19780726 [428]
If he ate 4 of them, but it means he ate 2/5 muffins, 
4 muffins = 2/5 muffins
You substitute x muffins for how much muffins she baked in all -
2/5* x muffins = 4
2/5 multiply by 2/5 to cross it out. Do the same to the other side. 
x= 4 *5/2
x = 10 muffins
So there were 10 muffins in all
