Your friend tossed a fair coin when you weren’t around. She has a habit of messing with you every once in a while, and so there

zaharov [31]

Answer:

Step-by-step explanation:

Given that your friend tossed a fair coin when you weren’t around.

Let A be the event that she said the outcome is head

B1 = Event she lied and B2 = Event she did not lie

$P(B1) = \frac{1}{3} \\ P(B2) \frac{2}{3}$

P(AB1) = $\frac{1}{2} *\frac{1}{3} =\frac{1}{6}$

P(AB2) = $\frac{2}{3} \frac{1}{2} =\frac{2}{6}$

Required probability = P(B1/A)= $\frac{P(B1A)}{P(B1A)+P(B2A)} \\=\frac{\frac{1}{6} }{\frac{1}{6}+\frac{2}{6}} \\=\frac{1}{3}$

Are the following systems of linear equations? Why or why not?

8_murik_8 [283]

all are linear eqns since they follow the formula y = mx + c

1) y = 2x +15

2) 2x -4y = 12 can be rewritten as...

4y = 2x -12 =》 y = 1/2 x - 3

3) 2x - 2y = 12 can be rewritten as...

2y = 2x - 12 =》 y = x - 6

4) 3z -4x =18 can b rewritten as...

3z = 4x - 18 =》 z = 4/3 x - 6
