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.

If Jenny can read 7 books in 8 days, exactly how many days would it take her to read 20 books?

muminat

Answer:

<h2><em><u>23</u></em><em><u> </u></em><em><u>days</u></em></h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>,</u></em>

No. of days taken by Jenny to read 7 books

= 8

<em><u>So</u></em><em><u>,</u></em>

No. of days taken by her to read 1 book

$= \frac{8}{7}$

<em><u>Therefore</u></em><em><u>,</u></em>

No. of days taken by her to read 20 books

$= \frac{8}{7} × 20$

<em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

$= \frac{160}{7}$

<em>[</em><em>On</em><em> </em><em>dividing</em><em>]</em>

= 22.85.....

<em>[</em><em>On</em><em> </em><em>approximating</em><em>]</em>

= 23 days (approx. )

<em><u>Hence</u></em><em><u>,</u></em>

<em><u>Jenny</u></em><em><u> </u></em><em><u>will</u></em><em><u> </u></em><em><u>take</u></em><em><u> </u></em><em><u>23</u></em><em><u> </u></em><em><u>days</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>read</u></em><em><u> </u></em><em><u>20</u></em><em><u> </u></em><em><u>books</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
