Answer:  √3 and √2 are irrational numbers;

                -\dfracP{1}{16} and 0 are rational numbers.

Step-by-step explanation:  We are given to classify the following numbers as rational or irrational:

\sqrt{3},~~-\dfrac{1}{16},~~0,~~\sqrt{2}.

<u><em>Rational number:</em></u>   The digits after the decimal are either repeating or terminating.

<u><em>Irrational number:</em></u>  The digits after the decimal are non-terminating and non-terminating.

(a) We have

\sqrt{3}=1.732050807568877~.~.~.

Since the digits after the decimal are non-terminating and non-repeating, so √3 is an IRRATIONAL number.

(b) We have

-\dfrac{1}{16}=-0.0625.

Since the digits after the decimal are terminating, so -\dfrac{1}{16} is a RATIONAL number.

(c) We have

0=0.000.

Since the digits after the decimal are  terminating, so 0 is a RATIONAL number.

(d) We have

\sqrt{2}=1.414213562373095~.~.~.

Since the digits after the decimal are non-terminating and non-repeating, so √2 is an IRRATIONAL number.

Use a graphing calculator to find the value of the correlation coefficient r to determine if there is a strong correlation among
OlgaM077 [116]

The value for r = - 0.8535 ,  there is strong correlation between the variables.

<h3>What is a correlation coefficient  ?</h3>

Correlation coefficient describes the relationship between the two variables in the data .

The data given is

(1, 7), (2, 5), (3, -1), (4, 3), (5, -5)

Assuming Linear Regression ,

The data is plotted on the graphing calculator

The value for r = - 0.8535

as the value is in the range of - .85 to -1 , therefore there is strong correlation between the variables.
