Its decagon. cause it has 10 corners.
Answer:
-6
Step-by-step explanation:
Move the variable to the left hand side and change its sign.
5 - 2x + 4x = -7
Collect like terms.
- 2x + 4x = - 7 - 5
2x = - 7 - 5
Calculate the difference.
2x = -12
Divide both sides.
x = -6
Answer:
The player should be required to pay $5 to make this a fair game.
Step-by-step explanation:
U ~ Uniform(0, 10)
E[U] = (0 + 10)/2
= 5
X | U ~ Poisson(U)
E[X | U] = U
By law of total probability for expectations,
E[X] = E[E[X|U]] = E[U] = $5
Therefore the player should be required to pay $5 to make this a fair game.
Answer:
1 3/4
Step-by-step explanation:
8.25-6.5
Answer:
x <-14.5
Step-by-step explanation:
2x + 2(x+5) <+4(8 – 20)
Distribute
2x+2x+10 < 4 (-12)
4x +10 < -48
Subtract 10 from each side
4x+10-10 <-48-10
4x< -58
Divide each side by 4
4x/4 < -58/4
x <-14.5
