Answer:
Check Explanation
Step-by-step explanation:
The random variable X is the possible net amount that leaves or enters one's hands. It is the amount of winnings!
X can take on value of -($7 × 4) = -$28
(That is, none of the four raffle tickets bought is picked to win)
X can also take on value of [$150 - ($7 × 4)] = $122
(That is, one of the four raffle tickets bought is picked to win)
For the probability distribution function, we find the probabilities of the different amount of winnings.
First of, probability of losing = (96/100) = 0.96
Then, probability of winning = (4/100) = 0.04
Probability density distribution is then given as
X | probability
-$28 | 0.96
$122 | 0.04
To go a step further, expected winnings would be
E(X) = Σ xᵢpᵢ = (-28)(0.96) + (122)(0.04)
= -26.88 + 4.88 = -$22
The expected winnings show that this is not a risk worth taking.

461 because you take 506-45 to find x(the unknown number)
Answer:
A) (Triangle) So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle. The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
B) We know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius.
C)The parallelogram area can be calculated, using its base and height.
Area = ½ × d1 × d2 sin (y)
All Formulas to Calculate Area of a Parallelogram
Using Base and Height A = b × h
Using Trigonometry A = ab sin (x)
Using Diagonals A = ½ × d1 × d2 sin (y)
D)Area of a trapezoid is found with the formula, A=(a+b)/2 x h. Learn how to use the formula to find area of trapezoids.
Hope this helps!
