5) adding 2 each time
i can't help with number 6 sorry i hope number 5 helps
Answer:
Using the quadratic formula to solve 5x = 6x^2 – 3, what are the values of x?
5x = 6x^2 – 3
Subtract 5x from both sides:
0 = 6x^2 – 5x – 3
a = 6, b = -5, c = -3
x = (-b ± √(b^2 - 4ac))/(2a)
x = (-(-5) ± √((-5)^2 - 4(6)(-3)))/(2(6))
x = (5 ± √(25 + 72))/12
x = (5 ± √(97))/12

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
