Which is a zero of the function defined by 2x² + x - 45? a. -9b. -5c. 5d. 9 show some work

Hence,

The relative frequency of landing magnet side up is :

                                   0.26  

The relative frequency of landing magnet side down is:

                                  0.74

We know that a relative frequency is the ratio of the frequency of an outcome to the total number of outcomes.

We are given an frequency as:

Magnet Side UpMagnet Side Down              Total

       13                              37                                     50

Hence, the relative frequency is calculated as dividing each of the frequency by total frequency i.e. 50.

i.e. The table is given as:

Magnet Side UpMagnet Side Down              Total

   13 /50=0.26              37 /50=0.74                   50/50=1
