Answer:
Infinetly many solutions. No matter what you plug in, it always comes out equal.
Step-by-step explanation:
Answer:
it saves 2.5 minutes
Step-by-step explanation:
The expected value of a random variable is the sum of products of possibilities and the probability of each.
Here, you have a probability of 0.9 of saving 5 minutes, and a probability of 0.1 of adding 20 minutes.
__
The expected value of the shortcut is ...
0.9(-5) +0.1(20) = -4.5 +2.0 = -2.5
The shortcut is expected to save 2.5 minutes on average.
_____
<em>Additional comment</em>
The probability of 0.9 comes from the 9 of 10 trips that result in a time saving.
The domain is all possible x values. For linear graphs, the domain is usually all real numbers.
Answer:1/4x+y=-3
Step-by-step explanation:
You have to move 1/4x to the left side by adding the inverse of 1/4x, -1/4x to each side. Then you have 1/4x+y+3=3. After this you have to use the subtraction property of equality. Then your answer is 1/4x+y=-3
Answer:
Empirical Probability that a family's first child will be born with this syndrome is 0.0002.
Step-by-step explanation:
Empirical Probability of an event E is defined
Let E: Event that the child born has a certain syndrome.
Now here, total number of times experiments performed = 50,000
The number of favorable outcome = 1
Hence, here the Empirical Probability that a family's first child will be born with this syndrome is 0.0002.
