The table shows the number of students in a class that received letter grades on 2 recent exams. The first exam is shown across
the top and is summarized as Aų, B1, and C1, and the second exam is in the first column, A2, B2, and C2. Given that a student earns
an A on the first exam, what is the probability the student earns a C on the second exam?
A)
3%
B)
17%
20%
D)
25%

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
