1 Travis will place 2 red marbles, 6 blue marbles, and 12 yellow marbles in a sack.
He will then choose one marble at random.
The table below shows the theoretical
probability of a particular color being
chosen.
Color
Frequency
Red
10%
Blue
30%
Yellow
60%
If Travis pulls 120 marbles out of the sack,
with replacement after each pull, which is
the most reasonable prediction of the
number of marbles that will be red or blue?
A 72 B 54 C 48 D40

the answer is 288..

hope this

i need the options

step-by-step explanation:

unless if u could do my questions, if not i wouldn't want to

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
