Answer:

The probability that a woman will be picked from room B is 0.34.

Step-by-step explanation:

There are 13 persons in room A, which 10 are women. So, the probability that a woman gets picked to be transfer to room A is 10/13 = 0.77.

Then, in room B there will be a total of 9 persons, assuming that a woman got picked from room A, the probability of that a woman will be picked from room B is 9/4 = 0.44 x 0.77 = 0.34.

\left \{ {{7x - 3y=25}simplify*(5) \atop {2x + 5y=95}simplify*(3)} \right.

\left \{ {{35x - \diagup\!\!\!\! 15 y=125} \atop {6x + \diagup\!\!\!\! 15y=285}} \right.

\left \{ {{35x =125} \atop {6x =285}} \right.

41x = 410

\boxed{x=10}

<span>Replace the value of "x" in the second equation (II) to find the value of "y", thus:

2*(10)+5y = 95
20+5y=95
5y=95-20
5y=75
y =  \frac{75}{5}
\boxed{y=15}

Alex
Hello!

1 minute 3 seconds = 63 seconds

We must found out 63 is 90% of what number, using the percentage formula:

90 * 100 / 63 = 70

70 seconds = 1 minute 10 seconds

So, Niki's time for one lap is 1 minute 10 seconds (70 seconds).
