Désolé pour les erreurs, mais le français n'est pas ma langue maternelle.

Prenant un tiers du temps total, ce qui reste est

1-\dfrac{1}{3}=\dfrac{2}{3}

Si le joueur passe les trois quarts de ce temps à s'échauffer, cela signifie qu'il jouera le dernier quart-temps:

\dfrac{2}{3}\cdot\dfrac{1}{4}=\dfrac{1}{6}

Ainsi, le joueur joue un sixième du temps total.  

Si le match dure 90 minutes, un sixième est 90/6=15 minutes.

Kisachek [45]

Answer: The percent of female commissioned officers in the army in 1940= 5.3%

Step-by-step explanation:

We are given that ,

The number of commissioned officers reported by U.S. Army  in 1940 = 17,563

The  number of female commissioned officers = 939

Then , the number of female commissioned officers in the army in 1940  would be :-

\dfrac{\text{\text{Number of Female officers}}}{\text{Total commissioned officers }}\times100

=\dfrac{939}{17563}\times100=5.3464670\approx5.3\%

Hence, the percent of female commissioned officers in the army in 1940= 5.3%
