<h3>
Answer: 4</h3>
============================================================
Explanation:
Refer to the table below (attached image). I've copied your table and added a third row at the bottom. This new row is the result of multiplying each payout value with the corresponding probability.
Example: for the first entry of this row, have 2*0.45 = 0.9
Once that third row is filled out, you add up everything in that row. That will lead to the expected value.
The expected value is: 0.9+1.2+0.6+0.8+0.5 = 4
Interpretation: You expect, on average, to win $4 each time you play the game. This assumes that the cost to play the game is 0 dollars. If the cost is something else, then it will affect the expected value.
Because the expected value is not 0, this game is not mathematically fair (the bias is leaning in favor of the player).
Answer:
Angle 1: 95 degrees
Angle 2: 85 degrees
Angle 3: 95 degrees
Step-by-step explanation:
Vertical angles are opposite and equal so in this case angle 1 and 3 are vertical and so are 2 and 85°
So that means angle 2 also equals 85 degrees and because of supplementary angles the other angle must add up to equal 180 degrees
85 + ? = 180
?=95
So both angle 1 and 3 equal 95 degrees
Answer:
50 free throws
Step-by-step explanation:
3 : 10 = 15 : x
3x = 150

Answer: 34.18%
Step-by-step explanation:
Given: On Saturday, Number of cupcakes sold = 
dozens
= 
dozens
[ 1 dozen = 12 items]
On Friday, Number of cupcakes sold = 
dozens
= 
dozens
[ 1 dozen = 12 items]
Increase in cupcakes = 318-237=81
Percent increase in cupcakes sales from Friday to Saturday = 
= 34.18% (approx)
The approximate percent increase in cupcake sales from Friday to Saturday = 34.18%
