Probability of 2 sets going to tie-breaker = 0.19*0.19 = 0.0361
there are 3 ways that 2 out of 3 sets are tiebreakers
so required probability = 3 * 0.0361 = 0.1083
= 10.83%
1)
x^2 + 4 = 0 Subtract 4 from each side
x^2 = -4
You cannot square a number to get a negative number. No real solution. (If you have learned about imaginary numbers, answer is 2i)
2)
<span>x^2+x-6=0 Factor. 3 and -2 add up to 1, and multiply to -6
(x+3)(x-2) = 0
Zero Product Property: Which numbers would put a zero in one of the parentheses?
x = -3 or x=2
3) </span><span>x^2-6x+7=0
Completing the Square:
Take half of b (-6), square it, and add/subtract that coefficient
x^2 - 6x + 9 - 9 + 7 = 0
(x -3)^2 - 2 = 0 Add 2 to both sides
(x-3)^2</span> = 2 Take the square root of both sides
<span>(x-3) = </span>√2 or -√2 Add 3 to both sides
<span>x = 3 + </span>√2 or 3 - √2<span>
</span>
Answer: 6x+8
Step-by-step explanation: the number, which is the letter can be any letter you want, that doesn’t matter. So when it says six times a number, I just used x as an example. Once you have that just add a +8 because increased means add.
Answer: 1/18
Step-by-step explanation: 1/3 x 6/1 ----> 1/3 x 1/6 = 1/18
Answer:
-2
Step-by-step explanation:
the equation is y=2x-2 and the constant is the y-intercept
