You
can estimate the product
by
estimating
a little low, 10, and estimating
2.95 a little high, 3, to get approximately
dollars. You can
also use the calculator to
compute a more exact answer and then round the answer to the nearest 10 dollars, as
suggested by the answer choices. The calculator yields the decimal
which rounds to
30 dollars.
Thus the correct answer is Choice C, $30
.
5. A certain jar contains 60 jelly beans — 22 white, 18 green, 11 yellow, 5 red, and 4 purple. If a
jelly bean
is to be chosen at random, what is the probability that the jelly bean will be neither
red nor purple?
A. 0.09
B. 0.15
C. 0.54
D. 0.85
E. 0.91
Explanation
Since there are 5 red and 4
purple jelly beans in the jar, there are 51 that are neither red nor
purple and the probability of
selecting one of these is
Since all of the answer choices are
decimals, you must convert the fraction
to its decimal equivalent, 0.85.
Thus the correct
answer is Choice D, 0.85
.
