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.

Alexeev081 [22]

Answer:

0.3164 = 31.64% probability the team wins all its conference games

Step-by-step explanation:

For each conference game, there are only two possible outcomes. Either the team wins it, or they lose. The probability of winning a game is independent of any other game. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

A football team has a probability of .75 of winning when playing any of the other four teams in its conference.

The probability means that p = 0.75, and four games means that n = 4

If the games are independent, what is the probability the team wins all its conference games?

This is P(X = 4). So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 4) = C_{4,4}.(0.75)^{4}.(0.25)^{0} = 0.3164

0.3164 = 31.64% probability the team wins all its conference games

0.145 as a fraction or a mixed number.
Vlad1618 [11]

we can convert any decimal to a fraction, by simply <u>using as many zeros at the bottom as there are decimals, and losing the dot atop</u>, now let's do so, notice we have 3 decimals, so we'll use 3 zeros.


\bf 0.\underline{145}\implies \cfrac{0145}{1\underline{000}}\implies \stackrel{simplified}{\cfrac{29}{200}}
