Answer:
x= -0.01984
Step-by-step explanation:
You divide both sides by 3125 to get x alone.
You get x=-0.01984

Answer:
1) n = 39916800
2) n = 1663200
3) n = 330
Step-by-step explanation:
1) If the blue balls are distinguishable as are the red balls
Then you can arrange these balls in the following ways, we must use a permutation
In totally we have 11 balls, then
n = 11P11
2) If Blue balls are distinguishable, but the red balls are identical
In this case, we need to do a correction due to the red balls are identical and we cannot identify the difference when we interchange two red balls
![n = \frac{11!}{4!} = \frac{39916800}{24} = 1663200](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B11%21%7D%7B4%21%7D%20%20%3D%20%5Cfrac%7B39916800%7D%7B24%7D%20%3D%201663200)
3) If the balls of each color are indistinguishable
We proceed equal to the before case but we include a correction due to blue balls also
![n = \frac{11!}{4!*7!} = \frac{39916800}{24*5040} = 330](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B11%21%7D%7B4%21%2A7%21%7D%20%3D%20%5Cfrac%7B39916800%7D%7B24%2A5040%7D%20%3D%20330)
Answer:
121
Step-by-step explanation:
180°-74° = 106°
106°= x-15°
106+15= X
x= 121
(correct me if im wrong plz)
