Hello!
Each time, there will be a 1/2 chance of tossing a head. Therefore, we multiply our two probabilities.
1/2(1/2)=1/4
Therefore, we have a 1/4 or 25% chance of tossing two heads in a row.
I hope this helps!
Answer:
y = - 9
Step-by-step explanation:
Substitute in -1 for x
8(-1) - 2y = 10
-8 - 2y = 10
Subtract -8 from both sides
-8 - (-8) cancels out to 0
10 - (-8) = 18
We are left with:
-2y = 18
Divide by -2 on both sides.
-2y/-2 = y
18/-2 = -9
y = -9
