False: 10 • 0.02=
when anything is multiplied by two, move a decimal once to the right~ if it is a whole number, add a zero.
0.02-> move one decimal to the right= 0.2
Therefore, 2 is not equal to 10 • 0.02
10 • 0.02= 0.2
BUT 10 • 0.2= 2

2. Starting at a fixed time, each car entering an intersection is observed to see whether it turns left (L), right (R), or goes

jasenka [17]

Answer:

Natural numbers (integers greater than zero)

X = 3, 5, 4, 4, 3

Step-by-step explanation:

The least number of cars that can be observed in this experiment is 1, if the first car turns left. On the other hand, the experiment could go on forever if no car ever turns left, thus the highest number of cars approaches infinite.

The possible values of X are integers greater than zero, which are known as the Natural numbers.

If X = number of cars observed, simply count the number of letters in each outcome for the value of X:

Outcome = RRL, AARRL, AARL, RRAL, ARL

X = 3, 5, 4, 4, 3
