Answer:
b) Prob (at least 1 red): 2/3
Prob (R,R) = 1/9
Prob (B,B) = 4/9
Step-by-step explanation:
P(at least one red): 1/3 + 1/3 = 2/3
Prob(R,R): 1/3 · 1/3 = 1/9
Prob(B,B): 2/3 · 2/3 = 4/9
I believe it’s (4,22)
i’m sorry if that’s not correct
have a great day!:)
<u>Answer-</u>
<em>The coordinates of the orthocenter of △JKL is (-4, 8)</em>
<u>Solution-</u>
The orthocenter is the point where all three altitudes of the triangle intersect. An altitude is a line which passes through a vertex of the triangle and is perpendicular to the opposite side.
For a right angle triangle, the vertex at the right angle is the orthocentre of the triangle.
Here we are given the three vertices of the triangle are J(-4,-1), K(-4,8) and L(2,8)
If the triangle JKL satisfies Pythagoras Theorem, then triangle JKL will be a right angle triangle.
Applying distance formula we get,
As,
Therefore, the vertex at K (-4, 8) is the orthocentre.
Answer:
c
Step-by-step explanation:
The square of the equation 2 – 12x – 20=0 is
What is a quadratic equation?
A quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0.
a+bx+c , a, b, c are integers .
formula: −b±√b2−4ac/2a
Given equation ,
2 -12x-20=0
By comparing with the quadratic equation
Here, a=2, b= -12, c= -20.
X=−b±/2a
X= -(-12) + /2(2)
X=12+- /4
X=12+- /4,
X=12+- (-4)/4
X=12+(-4)/4 and x=12-(-4)/4
X= 12-4/4 and x=12+4/4
X=8/4 and x= 16/4
X=2 and x= 4
Therefore, the square of the equation 2x2-12x-20=0 is x= 2 and x=4.
