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.

What is 8.25 as a fraction in simplest form?

vekshin1

8 is a whole number, so this will be the whole number part of our mixed number.

0.25 is a decimal, where 25 is in the HUNDREDths place, so we write 25 as a fraction over 100.

$\sf\dfrac{25}{100}$

Simplify by dividing 25 to the numerator and denominator.

$\sf25\div25=1$
$\sf100\div25=4$

So our fraction is $\sf8\dfrac{1}{4}$

0.55 is a decimal, where 55 is in the HUNDREDths place, so we write 55 as a fraction over 100.

$\sf\dfrac{55}{100}$

Simplify by dividing 5 to the numerator and denominator.

$\sf55\div5=11$
$\sf100\div5=20$

So our fraction is $\sf\dfrac{11}{20}$

$\sf\dfrac{5}{8}$

To convert this to a decimal, just divide 5 / 8

$\sf5\div8=0.625$
