Here is how you would set it up...
You would to 12/100 = x/2 and cross multiply and solve by division. I believe. I'm almost positive that's how you do it. If that don't work out, comment and I'll respond.
Answer:
Step-by-step explanation:
There are 12 E's out of 100 tiles.
Tiles are not replaced.
<u>The probability of each of first 4 E's is:</u>
- The first E ⇒ P(E) = 12/100 = 3/25
- The second E ⇒ P(E) = 11/99 = 1/9
- The third E ⇒ P(E) = 10/98 = 5/49
- The fourth E ⇒ P(E) = 9/97
<u>The probability of 4 E's is:</u>
- P(4 E's) = 3/25*1/9*5/49*9/97 = 3 / (5*49*97) = 3 / 23765
(x²)-³ =<u> 1 </u> = <u> 1 </u> = <u> 1 </u><u /> = <u> 1 </u>

Answer:
3.
1.x=√(15²-12²)=√81=9
2.x=√(6²+6²)=6√2
3.c=√(√19²-√7²)=√(19-7)=√12
Step-by-step explanation:
4.h=10
a=b=x
we have
by using Pythagoras law
h²=x²+x²
100=2x²
x²=50
x=√50=5√2
both legs =5√2
-2x + 6 = 30 - 6x
--> -2x + 6x = 30 - 6

</span><span>--> x = 24/4
</span><span>--> x = 6</span>
