Answer:
<h3>2</h3>
Step-by-step explanation:
The whole number will be 2 because 2.25 is closer to 2 than 3 when we round to whole number
When you have to repeatedly take the same test, with constant probability of succeeding/failing, you have to use Bernoulli's distribution. It states that, if you take 
tests with "succeeding" probability 
, and you want to "succeed" k of those n times, the probability is
In your case, you have n=18 (the number of tests), and p=0.3 (the probability of succeeding). We want to succeed between 8 and 12 times, which means choosing k=8,9,10,11, or 12. For example, the probability of succeeding 8 times is
you can plug the different values of k to get the probabilities of succeeding 9, 10, 11 and 12 times, and your final answer will be

Step-by-step explanation:
Respuesta:
-4;
-1
Explicación paso a paso:
Dado :
-2- | -2 | - | -3 | +3
Los números entre barras verticales son valores absolutos y se tratan como positivos:
-2 - +2 - +3 + 3 = - 2-2-3 + 3 = - 4
| -1 | + | -1 | - | -3 |
Los números entre barras verticales son valores absolutos y se tratan como positivos
1 + 1 - + 3 = 1 + 1-3 = - 1
For this case you can model the problem as a rectangle triangle where you have the length of the opposite leg and the adjacent leg.
Therefore, the angle sought is given by:
theta = Atan (8/15)
theta = 28.07 degrees
Answer:
The angle between its diagonal and a longer edge is:
theta = 28.07 degrees
