Answer: A linear relationship
Step-by-step explanation:
From the graph we can see as the number of years increasing the average price of a PC decreasing at a constant rate.
It is forming a straight line and its equation is similar to equation of line
, where m= -39 which is the rate of change of average price.
Hence, the relationship between the average price of PCs and the number of years that have passed since 2000 is a linear relationship.
Answer:
at least 9 students in each cohort.
Step-by-step explanation:
Given that :
In a class, there are 25 students and each of them is either a sophomore, a freshman or a junior. We have to determine the number students in the same cohort.
Let us suppose there are equal number of students in each of the cohort.
Now let us assume that the number of the students in each cohort be 8, i.e. each as a freshman, a junior or a sophomore. Therefore, the total number in the all the cohorts will be 24 students only.
Thus, we can say that there are at least freshman, at least
sophomore or at least
junior in each of the cohort.
