Answer:
AA similarity (Postulate).
Step-by-step explanation:
The AA Similarity Postulate states that <em>two triangles are similar if all their corresponding angles are congruent, and their corresponding sides are proportional.</em>
In this case:
∡ACE ≅ ∡DBE (Given)
∡BED ≅ ∡AEC (Vertical Angles Theorem)
For Proportionality, you will have to get more information on the measurements of the sides. As side measurements are not given, you cannot use any similarities based on sides to prove the similarities of the triangles.
1 = Hundred tens of thousandths.
0 = tens of thousandths.
6 = thousandths.
5 = hundredths.
3 = tenths.
4 = units.
Using the expected value of a discrete distribution, it is found that:
a) His expected value is of -$2.5.
b) The fair price of a ticket is of $0.5.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the distribution for the net value of the ticket is:
Item a:
The expected value is given by:
His expected value is of -$2.5.
Item b:
With an unknown ticket price, the distribution is:
The game is fair if E(X) = 0, hence:
0.5 - x = 0
x = 0.
The fair price of a ticket is of $0.5.

Answer:
It is multiplied by and reflected about the y-axis.
Step-by-step explanation:
In order to transform the graph of into the graph , we have to multiply it by so that it becomes .Then we have to reflect it over the y-axis, and we do this by multiplying its domain by -1. This gives us .
