First add up the number of times spun. We get 50 spins now add up the number of spins that we didn't get 1. For that we get 42 now divide 42/50= 21/25. So for every 25 spins 21 of them will probably be something other than 1. Your answer is 21/25

2. The table below shows that the distance d varies directly as the time t. Find the constant of variation and the equation which describes the relation.

<h2><u>Solution</u>:-</h2>

Since the distance d varies directly as the time t, then d = kt.

Using one of the pairs of values, (2, 20), from the table, substitute the values of d and t in d = kt and solve for k.

$\sf{\rightarrow{d = kt}}$
