50 total students

  • 20 girls

Explanation:

total students: 100%

----------------

  • 60% → 30
  • 1% → 30/60
  • 1% → 0.5
  • 100% → (0.5 * 100)
  • 100% → 50

number of girls:

  • total students - number of boys
  • 50 - 30
  • 20

Que forma tiene un hexágono y como se entre si?
Mars2501 [29]

Answer:

Al igual que los cuadrados y los triángulos equiláteros, los hexágonos regulares encajan sin ningún espacio para enlosar el plano (tres hexágonos se encuentran en cada vértice), por lo que son útiles para construir mosaicos.

<h3>What is probability distribution?</h3>

Probability distribution is the statistical model which represent all the achievable and similar values of a random variable that it can possess in a specified range.

A teacher assigns a score from 1 to 4 to each student project. the table below shows the probability distribution of the scores for a randomly selected student.

  • Probability distribution score:      1,       2,       3,       4,
  • x probability: p(x)                      0.06,  0.20,  0.48,  0.26

In the above data, the height probability of selection is 0.48. This probability belongs to the score 3.    

Thus, the score which is assigned from 1 to 4 by the teacher to each student for the project and is most likely to be is 3 with 0.48 probability.
