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%

the answer is 489

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
