Step-by-step explanation:

Total balls = 12

Probability of 2 black balls = 2/ 8 = 1/4

Probability of 2 red balls = 2/4 = 1/2

Probability of both red and black = 2/12 = 1/6

P(B) = 8/12

P(R | B) = 4/11

P(B ∩ R) = 8/33

The probability that the first ball chosen is black and the second ball chosen is red is about 24% percent.

Which equation has solutions of 6 and -6? x2 – 12x + 36 = 0 x2 + 12x – 36 = 0 x2 + 36 = 0 x2 – 36 = 0
Anastasy [175]
X^2 – 12x + 36 = 0
(x-6)(x-6)=0
x=6 x=6
Not a solution

x^2 + 12x – 36 = 0
Doesn't factor
Not a solution

x^2 + 36 = 0
x=√-36
Not a solution

x^2 – 36 = 0
(x-6)(x+6)= 0
x=6 x=-6
Solution


ANSWER: The equation with solutions of x=6 and x=-6 is the last choice: x^2 - 36= 0.

Hope this helps! :)

eimsori [14]

Answer:

1/2 cup of milk

Step-by-step explanation:

Given

Total cup of milk needed = 3/4 cup of milk

Amount she has = 1/4 cup of milk

The amount of milk she needed = Total - Amount she has

Amount she needed = 3/4 - 1/4

Amount she needed = (3-1)/4

Amount she needed = 2/4

Amount she needed = 1/2

Hence she needs 1/2 cup of milk more
