En una prueba de natación, Mario hizo el recorrido en ¾ de minuto y David en 4/5 de minuto ¿Cuál es la diferencia entre los dos

slamgirl [31]

Answer:

3 segundos

Step-by-step explanation:

De la pregunta anterior, se nos dice que:

En un evento de natación, Mario hizo el curso en ¾ de minuto

1 minuto = 60 segundos

Por lo tanto = 3/4 de minuto

= 3/4 × 60 segundos

= 45 segundos

David completó el curso en 4/5 de un minuto.

1 minuto = 60 segundos

Por lo tanto = 4/5 de un minuto

= 4/5 × 60 segundos

= 48 segundos

La diferencia entre los dos competidores se calcula como

48 segundos - 45 segundos

= 3 segundos.

Por lo tanto, la diferencia entre los dos competidores = 3 segundos.

The table shows the results of a survey in which 10th-grade students were asked how many siblings (brothers and/or sisters) they

lesantik [10]

Answer:

70%

Step-by-step explanation:

Given

Number of Siblings: || 0 || 1 || 2 || 3

Number of Students: || 4 || 18 || 10 || 8

Required

Determine the probability of a student having at least one but not more than 2 siblings

First, we have to determine the total number of 10th grade students

$Total = 4 + 18 + 10 + 8$

$Total = 40$

The probability of a student having at least one but not more than 2 siblings = P(1) + P(2)

Solving for P(1)

P(1) = number of students with 1 sibling / total number of students

From the given parameters, we have that:

Number of students with 1 sibling = 18

So:

$P(1) = \frac{18}{40}$

Solving for P(2)

P(2) = number of students with 2 siblings / total number of students

From the given parameters, we have that:

Number of students with 2 siblings = 10

So:

$P(2) = \frac{10}{40}$

$P(1) + P(2) = \frac{18}{40} + \frac{10}{40}$

Take LCM

$P(1) + P(2) = \frac{18 + 10}{40}$

$P(1) + P(2) = \frac{28}{40}$

Divide numerator and denominator by 4

$P(1) + P(2) = \frac{7}{10}$

$P(1) + P(2) = 0.7$

Convert to percentage

$P(1) + P(2) = 70\%$

Hence, the required probability is 70%
