Mr. Doodle’s grade distribution over the past 3 years for a course in college algebra is shown in the chart below.Grade Number
A 45

B 180

C 210

D 95

F 65

I 5



A=45 b=180 c=210 d=95 f=65 i=5

Answer 1

13/120

Answer 2

this is the correct question, sorry for the repeat

Answer 3

empirical means we take what is given instead of trying to interpolate the data

Answer 4

#of Fs
--------------
total # of grades

Answer 5

in this case, if we go off your document

65/sum of it all

Answer 6

i thought u add all the number and divide by the number of the letter you looking for which is F

Answer 7

almost; you got the order flipped about.

probability is defined as:\[\frac{\#.desired.outcomes}{\#.total.outcomes}\]

Answer 8

\[\frac{65}{sum.of.all}=\text{ empirical prob.}\]

Answer 9

it didnt show explanation

Answer 10

it dint show MY explanation? or it dint show an explanation in the material you have?

Answer 11

65/600=.1083333333

Answer 12

# of Fs
-------------- = emp. prob.
total # of grades

Answer 13

if that 600 is good, then thats what it would amount to yes

Answer 14

it total is 600

Answer 15

then the prob tends to truncate to 4 decis

.1083 looks good to me
