Answer:
A) There is a 50% chance the game ends in a tie, 10% chance you win (and therefore a 40% chance you lose).
expected value = (50% x 20) + (10% x 50) + (40% x 0) = 10 + 5 + 0 = 15
B) There is a 50-50 chance of winning and there are no ties.
expected value = (50% x 50) + (50% x 0) + = 25 + 0 = 25
C) There is an 80% chance you lose and a 10% chance you win or tie.
expected value = (10% x 20) + (10% x 50) + (80% x 0) = 2 + 5 + 0 = 7
The expected value of an event is determined by adding up all the possible outcomes multiplied by their respective value.
You should prioritize your first customer since they are entitled with your full attention being the one who availed your service first. You can ask the second customer if she can wait. But if the second customer would be so persistent, you can ask permission from the first customer if she is not in a hurry and that you would entertain the second customer first.
Answer: a) the type of exposure to Geomyces destructans; whether the bats became sick with WNS
Explanation: The independent variable refers to the variables employed by the experimenter to use as a tool to observe changes in the dependent variable. In an experimental study, the independent variables are usually the different controls adopted for the experiment. In the scenario above, the independent variable is the type of exposure to Geomyces destructans which each of the groups are exposed to. These variation in control in which the different groups are exposed to may result in different response within the group which is the change in WNS. These response due to exposure to different control is called the dependent variable.
Answer:
7.32%
Explanation:
<em>The price of a bond is the present of its interest payment and the present value of redemption value (RV</em>
Present value of the Redemption Value (RV) =
FV× (1+r/2)^(-2×n)
FV- 2000, r- yield rate, r/2= 6.74%/2 = 3.37%, n-22
=2000× (1.0337)^(-2×22)
= 465.233
Present Value of the coupon payment =Price of bond - PV of RV
= (106.657% × 2000) - 465.233
= $1667.90
PV of coupon payment= A × (1-(1+r)^(-2×n)
A- semiannual coupon payment, r -yield
1667.90 = A × (1-(1.0337)^(-2*22))/0.0337
1,667.90 = A × 22.7710
A = 1,667.90/22.7710
A= 73.246
Annual coupon payment = 2× 73.246= 146.493
Annual coupon rate = coupon payment/ face value
= (146.493/2,000 )× 100
= 7.32%
