Answer:
2/9 = 0.22
Step-by-step explanation:
There are two ways to pick the first number odd and less than 5: 1 and 3.
With each of these, the second number drawn can be 1, 2, 3, 4, 5, 6, 7, 8 or 9.
This makes 18 total possibilities.
Out of these, the only ways to have a sum less than 5 are 1 and 1, 1 and 2, 1 and 3, and 3 and 1. This is 4 ways out of 18:
4/18 = 2/9 = 0.22
When doing this, we would have to first straight them all out, and as we see above, they are just all over the place, and then, we would have to set them up as a sequence.
![\left[\begin{array}{ccc}5x2 + 5y2 - 20x + 30y + 40 = 0\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D5x2%20%2B%205y2%20-%2020x%20%2B%2030y%20%2B%2040%20%3D%200%5Cend%7Barray%7D%5Cright%5D%20)
would be our first step in this problem mainly because it contains the most terms in this aspect.
Then we would then

, then,

.
These would only be our first 3 part of the sequence in this aspect.
The others would then be the following:

Thus, as we would have one more afterward, our last part of the sequence would then be the following.

I hope this was found helpful!

Answer: x = 6 plus-or-minus 3 StartRoot 10
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 12x + 36 = 90
Rearranging the equation so that it takes the the standard form of
ax² + bx + c, it becomes
x² - 12x + 36 - 90 = 0
x² - 12x - 54 = 0
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = - 12
c = - 54
Therefore,
x = [- - 12 ± √(- 12² - 4 × 1 × - 54)]/2 × 1
x = [12 ± √(144 + 216)]/2
x = [12 ± √360]/2
x = (12 ± 6√10)/2
x = 6 + 3√10
