There is a proportional relationship between minutes and dollars per minute, shown on a graph of
printing expenses. The graph passes through the point (1,430). What is the slope of the graph? What is
the unit rate? Complete the explanation.
The slope is
The unit rate is $
min. If the graph of a proportional relationship
passes through the point ( r), then r equals the slope and unit rate.

Astudent simplified a rational expression as shown.

Aclass consists of 55% boys and 45% girls. it is observed that 25% of the class are boys and scored an a on the test, and 35% of the class are girls and scored an a on the test. if a student is chosen at random and is found to be a girl, the probability that the student scored an ais

1. if we have 3 babies what is the probability they’re going to be all boys? 2. if we roll 2 die at the same time what is the probability of getting less than 10 on the first roll and a 5 on the second roll 3. if we have 3 babies what is the probability their is going to be 2 girls? 4. if we have 3 babies what is the probability of having no more than 1 girl? 5. it we have 3 babies and then have another 3 babies what is the probability of us having at least 1 boy and then having all girls?
