D) 7/5 seniors/year

The number of students graduating (the dependent variable, 'y') is affected by the year (the independent variable, 'x').

Δy/Δx

= (185-164)/(2017-2002)

= 21/15 (Reduce the fraction)

= 7/5

∴ the rate of change from 2002-2017 is 7/5 seniors/year.

7/5

Step-by-step explanation:

Use the ROC formula

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail

step-by-step explanation:

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
