Vladimir79 [104]

Answer:

Number of courses would best be considered a discrete variable and drive time would be considered a continuous variable.

Step-by-step explanation:

Discrete variable:

Countable amounts(0, 1, 2, 3,...)

Continuous variables:

Can be decimal values.

In this question:

The number of courses is a countable amount(0,1,2,3,...), you cant take half a course, for example, so it is discrete. Otherwise, drive time accepts half minutes, for example, 10.5 minutes, so is continuous.

Number of courses would best be considered a discrete variable and drive time would be considered a continuous variable.

Can two people with blue eyes have a child with brown eyes? Why or why not? also i really don´t really know the subject so i put
ohaa [14]

Answer:

Yes

Step-by-step explanation:

In the family the blue eyed people may have had a gene with brown eyes. So if both parents carry that gene even if they don't display it, it can be still shown because brown eyes are the most dominant trait.

BR Elder 1: BL  BR     BL Elder 2: BL BL   BL Elder 1: BL BL   BL Elder 2: BR BL

              <u>I                                  I</u>                                      <u>I                              </u>I

                      I                                                                        I

Parent 1: Blue gene  brown gene          Parent 2: Blue gene brown gene

                                           I<u>                                                                    </u>I

                                                                              I

                                                            Child Brown eyes: BR BL

Because the brown gene is dominant if the gene shows up in both parents the child would be more likely to have brown eyes than blue.
