The first one is proportional and the second one is not. Because for the first one you can see that if you divide the number of pens by the cost you'll get the same answer for every single one. But for the second one if you divide the number of minutes by words typed you get a different answer for each one. You can also see if it's proportional or not if you draw it on the graph and it's a straight line. If it is the relationship is proportional if it isn't it's not proportional. Hope that makes sense :)

Determine whether the relationship between the two quantities shown in the table or graph is linear. If so, find the constant rate of change. If not, explain your reasoning.  1. SOLUTION:  Analyze the table. The rate of change from 5 hours to 8 hours is  or 3 cents per hour. This is the same as therate of change from 8 hours to 12 hours,  or 3 cents per hour, and from 12 hours to 24 hours,  or 3 cents per hour. So, the rate of change is a constant 3¢ per hour.

How can we interpret probability?

Probability of an event is a measurement of how likely an event can occur as an outcome of a random experiment.

Probability ranges from 0 to 1, both inclusive. Events whose probability is closer to 0 are rarer to occur than those whose probabilities are closer to 1 (relatively).

Since it is given that:

The chance of a customer receiving a blue pen = 0.008The chance of a customer receiving a blue tote bag = 0.04

Both probabilities are too close to 0, than 1. So they both are very unlikely to occur.

Thus, it is very unlikely that a customer gets a blue tote bag, and it is very unlikely that a customer gets a blue pen (Option B).
