If an unfair coin is tossed into the air and drops without interruption, its probability of landing on heads is 0.51 whereas the

probability of landing on tails is 0.49. If the payoff for landing on heads is $0.99 and the payoff for landing on tails is $1.01 and it costs $1 to play each game, should you play?
1)Yes, because over the long run your expected value is greater than the lowest payoff

2)No, because over the long run your expected value is lower than the lowest payoff

3)Yes, because over the long run your expected value is greater than the cost to play

4)No, because over the long run your expected value is less than the cost to play

Answer:

  4)  No, because over the long run your expected value is less than the cost to play

Step-by-step explanation:

The expected value is ...

  0.51×0.99 + 0.49×1.01 = 0.5049 +0.4949 = 0.9998

This expected value is less than the cost to play, so you will lose money in the long run. You should not play.

Which of the following theorems verifies that ABC ~ STU?
Lunna [17]

Answer:

B. AA

Step-by-step explanation:

The diagram given shows that two angles in ∆ABC are congruent to two corresponding angles in ∆STU.

Invariably, the third unknown angle of both triangles would also be equal going by the third angle theorem.

Thus, based on the AA Similarity Theorem which says that two triangles are similar to each other if two corresponding angles of one is congruent to two angles in the other, ∆ABC ~ ∆STU.

Help please thank you!!!!

1. You have that:

 - The trapezoids are similar.
 - The larger  base of the smaller trapezoid is 18 m and its area is 310 m².
 - The larger base of the larger trapezoid is 32 m.

 2. Then:

 Sides=18/32
 Sides=9/16

 Area=(9/16)²
 Area=81/256

 3. Now, you can find the area of the larger trapezoid, as below:

 81/256=310/x
 81x=(310)(256)
 x=79360/81
 x=980 m²

 Therefore, the answer is: The area of the larger trapezoid is 980 m².

1.3n-0.03=-9 (solve for n) grade lvl. 7
bazaltina [42]

Hello from MrBillDoesMath!

Answer:

-6.9


Discussion:  

1.3n - 0.03 = -9     =>              multiply both sides by 100

130n - 3 = -900 =>

130n = -900 +3 =  -897 =>     add 3 to both sides

n = -897/130  =>

n =  - (69 * 13)/ (10*13) =>

n = - 69/10 = - 6.9




Thank you,

Mark drew two triangles and 8 arrows as part of a set of 13 shapes. The only other type of shape in the set is a circle. What fr
luda_lava [24]

Answer:

3/13

Step-by-step explanation:

First...

What we know

1. There is a set of 13 shapes.

2. With 2 triangles, 8 arrows, and circles.

Next...

Take the number of triangles and arrows and add them up.

2 + 8 = 10

Finally...

Convert it into the fraction 10/13 and subtract it by the total 13/13.

This results 3/13.
