Equation of the quadratic function represented by the graph is y=a(x-3)^2-1. What is the value of a?
2 answers:
Answer:
2
Step-by-step explanation:
The graph in question is a quadratic graph that has been translated by some units, say, a units. In the transformation language, we say that the graph has been stretched by the factor of 2 like this:
It means that the graph of has been moved by 3 units to the right, stretched by the stretch factor of 2 and moved downwards on y-axis by 1 unit.

Answer:
And for this case we can use the cumulative distribution function given by:
And using this formula we have this:
Then we can conclude that the probability that your bid will be accepted would be 0.41
Step-by-step explanation:
Let X the random variable of interest "the bid offered" and we know that the distribution for this random variable is given by:
If your offer is accepted is because your bid is higher than the others. And we want to find the following probability:
And for this case we can use the cumulative distribution function given by:
And using this formula we have this:
Then we can conclude that the probability that your bid will be accepted would be 0.41
