Answer:
The probability of not rain during the entire festival is 0.19
Step-by-step explanation:
The Complement Rule states that the sum of the probabilities of an event and its complement must equal 1.
In this case we have the probability of raining of each day, we need the probability of NOT raining.
First day= 45% chance of rain, the complement is 55%
Second day 55% chance of rain, the complement is 45%
Third day a 10% chance of rain, the complement is 90%
Fourth day a 10% chance of rain, the complement is 90%
Fifth day 5% chance of rain, the complement is 95%
To get the probability of NOT raining in the entire festival is the multiplication of all the complements.
P(not raining) = 0.55 x 0.45 x 0.90 x 0.90 x 0.95= 0.19

Answer:
<h3>A: x = -5</h3><h3>B: y = -5</h3>
Step-by-step explanation:
Function A:
(-5, -2), (-5, 7) It's not a function, because for x = -5 we have two different values of y!
The graph is a vertical line x = -5
Function B:
(7, -5), (-2, -5) It's a function.
The graph is a horizontal line y = -5
