P(Y) = 5/6
Since they are independent, P(X & Y) = P(Y) * P(X)
Therefore:
1/3 = 5/6 * P(X) Change 1/3 to 2/6, then multiply both sides by 6/5
2/6 * 6/5 = P(X)
2/5 = P(X)
Written as a decimal, P(X) = .40
The value of e:g is 2:7.
<h3>what is Ratio?</h3>
A ratio indicates how many times one number contains another.
Given:
e:f=3:7
f:g=2:3
Now take LCM of 2 and 7 i.e., 14.
e/f= 3/7= 3*2/7*2= 6/14
and, f/g= 2/3= 2*7/3*7= 14/21
So,
e/g= e/f *f /g
= 6/14*14/21
= 6/21
e:g = 2:7
Hence, the value of e:g is 2:7.

Answer:
two solutions : (0,-3) , (3,0)
Step-by-step explanation:
hello :
y= x² -2x -3 ...(*)
y= x -3....(**)
x²-2x-3 = x -3
x²-3x=0
x(x-3) = 0
x=0 or x-3=0
x=0 or x=3
but : y=x-3
1) x=0 y=0-3=-3
2) x=3 y=3-3=0
two solutions : (0,-3) , (3,0)
R = 34x - (4x + 180)
