On last week's math test, 32 students received passing grades and 16 students did not receive passing grades. What is the ratio of the number of students who passed the test to
the total number of students who took the test?
A
11 / 1
B
2/3
C
3/2
D
2/1

Option B.             The ratio of the number of students who passed the test to

the total number of students who took the test is 2/3

Step-by-step explanation:

Firstly, we have to find the total number of students who took the test, we can do that by adding the number of students who passed and the number of students who did not pass, so ...

32 + 16 = 48

Now we just write down the ratio between the number of students who passed the test and  the total number of students who took the test. So we get

32/48

Now we just simplify and get...

2/3

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
