B. Upside Down V- Shaped
When you draw it out, it looks like a upside down V.
1.49 × 10^8
*just move the decimal point 8 places to the right.
149,000,000
hope this helps :)
11,339,800 is 11,340,000 rounded to the nearest whole number
(How to find) Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.
(How to solve) Theoretical probability is a method to express the likelihood that something will occur. It is calculated by dividing the number of favorable outcomes by the total possible outcomes. The result is a ratio that can be expressed as a fraction (like 2/5), or a decimal
(How to experiment) Experimental probability is the results of an experiment, let's say for the sake of an example marbles in a bag. Experimental probability would be drawing marbles out of the bag and recording the results. Theoretical probability is calculating the probability of it happening, not actually going out and experimenting.
(Example) The theoretical probability of an event occurring is an "expected" probability based upon knowledge of the situation. It is the number of favorable outcomes to the number of possible outcomes. Example: Find the probability of rolling a 6 on a fair die.

Answer:
había 18 DVDs al principio
Step-by-step explanation:
si procedemos desde el final del problema , sabemos que :
total que le quedaba después de darle los CDs a Juan - lo que fue para la hermana = lo que le sobró
x - x/3 = 6
2/3*x = 6
x= 6 * 3/2 = 9
por lo tanto tenia x=9 DVDs después de entregarle a Juan los suyos
también sabemos que
DVDs que tenia al principio - lo que fue para Juan = 9 DVDs
y - y/2 = 9
y/2 = 9
y= 18
finalmente había y= 18 DVDs al principio
