<span>There are eight possible outcomes: HHH,HHT,HTH,HTT,THH,THT,TTH,TTT. Seven (all but HHH) have at most two heads. Three of these seven (HHT,HTH,THH) have at least two heads. The probability is therefore 3 in 7 or about 42.86%.</span>

K(3k−6)−7k(6k+10)=12
julsineya [31]

Answer:

k = -12/77

Step-by-step explanation:

OG problem: k(3k−6)−7k(6k+10)=12

Step-by-step:

3k - 6k - 42k - 70k = 12

-3k - 42k - 70k = 12

-7k - 70k = 12

-77k = 12

k = -12/77

Ill give brainliest <br> Triangle Sum Theorem CLASSWORK
zepelin [54]

Step-by-step explanation:

Sum of angles in a triangle = 180°.

Question 3:

We have 90° + 61° + (14x + 1)° = 180°.

=> 14x° + 152° = 180°

=> 14x° = 28°

=> x = 2.

Question 4:

We have 70° + 55° + (4x + 3)° = 180°.

=> 4x° + 128° = 180°

=> 4x° = 52°

=> x = 13.

2x^{2} +4x+1=0 <br> Solve for x.
Viefleur [7K]
2x^2 + 4x + 1 = 0

2x^2 + 4x + 1 - 1 = 0 - 1

2x^2 + 4x = -1

X(2x + 4) = -1

X = -1.

2x + 4 = -1
2x + 4 - 4 = -1 - 4
2x = -5
2x/2 = -5/2
X = -5/2.

I believe these are the solutions. If not you can use the quadratic formula to solve for the roots, solutions.
