Answer:
domain (-4,infinity) range (negative infinity, infinity)
Step-by-step explanation:
The domain is the x axis. the x axis starts at -4 and keeps going meaning it goes to infinity. the range is the y axis. the range has no determined starting point or end point meaning it goes to negative infinity and positive infinity
Answer:
do youu have some image? because I take a test about that
Step-by-step explanation:
The coin we choose is equally likely to be fair or unfair, since the ratio of fair to unfair coins is 2:2 = 1:1.
So, 50% of the times we pick a fair coin, which lands on heads with probability 50%.
The other 50% of the times we pick an unfair coin, which lands on heads with probability 90%.
Since these two events are mutually exclusive (a coin is either fair or unfair), the probability of having the coin to land on heads is
Simplifying
34 = 10 + 4q
Solving
34 = 10 + 4q
Solving for variable 'q'.
Move all terms containing q to the left, all other terms to the right.
Add '-4q' to each side of the equation.
34 + -4q = 10 + 4q + -4q
Combine like terms: 4q + -4q = 0
34 + -4q = 10 + 0
34 + -4q = 10
Add '-34' to each side of the equation.
34 + -34 + -4q = 10 + -34
Combine like terms: 34 + -34 = 0
0 + -4q = 10 + -34
-4q = 10 + -34
Combine like terms: 10 + -34 = -24
-4q = -24
Divide each side by '-4'.
q = 6
Simplifying
q = 6
