Answer:
<h2>x = 30°</h2>
Step-by-step explanation:
The angle 30° and 2x are complementary angles.
Two angles are called complementary angles, if their sum is one right angle (90°).
Therefore we have the equation:
30 + 2x = 90 <em>subtract 30 from both sides</em>
2x = 60 <em>divide both sides by 2</em>
x = 30
Answer:
The spinner is 3 times more likely to land on white.
Step-by-step explanation:
The spinner landed 57 times on white and 19 times on black.
57 is 3 * 19
Answer: The spinner is 3 times more likely to land on white.
Answer:
you should accept the $1,000 bill
Step-by-step explanation:
Given the information:
- $500 for rolling 1 or 2
- $400 for rolling 3
- lose $300 for rolling 4,5,6
P (rolling 1 or 2) = 1/6 + 1/6 = 2/6 = 1/3
P (rolling a 3) = 1/6
P (rolling 4 or 5 or 6) = 3/6 = 1/2
Hence, the expected value for 1 time is:
E = (1/3)*500 + (1/6)*400 - (1/2)*300
E = $166 + $66 - $150
E = $82
Expected value is linear so if you roll the die 10 times, expected value is: 10*82 = $820
The expected value is $82, meaning you should accept the $1,000 bill
Answer: 11.775
If you plug in the radius (0.5 because the radius is half of the diameter) and the height to the formula for volume of a cylinder you will get pi•0.5 squared•15 which when solved is 11.775.
