Question

if the data in the table were entered into a regression calculator to produce a scatterplot and trend line, which window size would display all the points? x y 2 5 5 16 6 20 10 29 12 36 17 53 0 less-than-or-equal-to x less-than-or-equal-to 20; 0 less-than-or-equal-to y less-than-or-equal-to 50 0 less-than-or-equal-to x less-than-or-equal-to 20; 0 less-than-or-equal-to y less-than-or-equal-to 60 0 less-than-or-equal-to x less-than-or-equal-to 50; 0 less-than-or-equal-to y less-than-or-equal-to 20 0 less-than-or-equal-to x less-than-or-equal-to 60; 0 less-than-or-equal-to y less-than-or-equal-to 20

Answer 1

Answer:

Option: B is the correct answer.

The window size that display all the points are:

0 ≤x ≤ 20  ;   0 ≤ y ≤ 60

Step-by-step explanation:

We are given a table of values as:

           x                       y

            2                      5

            5                      16

            6                      20

            10                     29  

            12                     36

            17                     53

Hence, all the x-values lie in the interval:

          0 ≤ x ≤ 20

Similarly,  we could observe that the minimum value attained by y is 5 and maximum value attained by y is 53.

Hence, all the y-values lie in the interval:

          0 ≤ y ≤ 60

Answer 2

Answer:

  0 less-than-or-equal-to x less-than-or-equal-to 20;

  0 less-than-or-equal-to y less-than-or-equal-to 60

Step-by-step explanation:

The range in values of x is from 2 to 17, so a suitable window would be 0 to 20.

The range in values of y is from 5 to 53, so a suitable window would be 0 to 60.

  0 ≤ x ≤ 20

  0 ≤ y ≤ 60
