Answer 2

hmmm, do you recall how to tell the difference between discrete and continuous?

Answer 3

Discrete data only take on particular values and no values in between

Answer 4

very good

can a persons weight take on "inbetween" values?
can a telephone number have "fractions"?

etc ...

Answer 5

so A and B ?

Answer 6

define the options for me as what you would consider their values to be continuous or discrete, and then we can refine them better

Answer 7

A is discrete .. right?

B is also discrete

c. is cont.

Answer 8

D is discrete.

E. is cont.

Answer 9

i think..

Answer 10

good try, it has errors, but a good try at least

discrete: can be divided into parts, can be assigned a 1-to-1 relationship with the natural number set {1,2,3,4,5,...}

A. Weight of an elephant
if it can be placed into a scale; it can read any output: continuous

B. Telephone number
we can count, 1 by 1, all telephone numbers: discrete

C. Temperature of a hot pizza
a temperature can be any value; continuous

D. Number of votes for a candidate
we can count each and every vote, 1 by 1; discrete

E. Speed of a race car
a car can go any speed it wants; continuous
