There is a 25% chance that they will have no injured players for one of their matches.
In total, there were 16 matches if you add them all up. In 4 of the matches, there were no injured players.
4 / 16 x 100 = 25%
Yes it is a 90 degree rotation clockwise.
Answer:
Total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Step-by-step explanation:
We have given number of students = 10
These 10 students are assigned to four dorm rooms a single, a double, a triple and a quad
So number of ways to assigned single student ![=^{10}C_1=\frac{10!}{1!9!}=10\\](https://tex.z-dn.net/?f=%3D%5E%7B10%7DC_1%3D%5Cfrac%7B10%21%7D%7B1%219%21%7D%3D10%5C%5C)
Now left student = 10 -1 = 9
So number of ways to assigned double student ![=^{9}C_2=\frac{9!}{2!7!}=36](https://tex.z-dn.net/?f=%3D%5E%7B9%7DC_2%3D%5Cfrac%7B9%21%7D%7B2%217%21%7D%3D36)
Now left student = 9-2 = 7
So number of ways to assigned triple student
=70
Now left student = 7 - 3 = 4
So number of ways to assigned quad student ![=^{4}C_4=\frac{4!}{4!0!}=1](https://tex.z-dn.net/?f=%3D%5E%7B4%7DC_4%3D%5Cfrac%7B4%21%7D%7B4%210%21%7D%3D1)
So total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
Answer:
Time = 149.688 seconds
Step-by-step explanation:
First the conversation rate of ft to miles is
1 foot = 0.000189 mile
So 3300 feet = 3300*0.000189
= 0.6237
3300 feet = 0.6237 mile
So the roller coaster traveled 0.6237 mile.
But the speed of the roller coaster is 15 mile/hour
To calculate for time
Speed = distance/time
Time = distance/speed
Time = 0.6237/15
Time = 0.04158 hour
Converting to seconds , we multiply time by 3600
Time in seconds = 0.04158*3600
Time = 149.688 seconds
