Answer:
They lost 15 games
Step-by-step explanation:
Multiply the percent by the number of games they played to find your answer:
75 x %20
75 x 0.2 = 15
84 square inches divided by 14 inches equals 6
84 divided by 14 = s
9 + 5 + 4 + 7 = 25
Ratio = 5 : 25
Ratio = 1 : 5 <==== answer
P(x > 6.9) = 1 - P(x < 6.9) = 1 - P[z < (6.9 - 5.1)/0.9] = 1 - P(z < 2) = 1 - 0.97725 = 0.02275.
Therefore P(x > 6) is about 2.5%
The time needed at 2 meters per second for both rounds would be 100/2 s or 50 seconds. For the first lane he already used 50/1.5 -> 33.33 seconds, so he would need to cover the other 50 meters in exactly 16.67. 50m divided by the 16.67 seconds he has left means he has to swim at a speed of 3 meters per second.
