To calculate expected value,
We can add up the probability of all possible events.
The 2 possible events are either winning $50 or losing the prize, which is $ - 50
Expected value =
50 x 40 % + (-50) x 60%
= $-10
So the answer is $-10
Answer:
A,B,D
Step-by-step explanation:
right on edge
Answer:
753
Step-by-step explanation:
m^2 =700^2 +460^-2 −2(700)(460)cos78
m^2 = 490000+211600-2(700)(460)(0.207912)
m^2 = 490000+211600-133895.12889
m^2 = 567704.87111
m=753.462=753
27x^3 - 12x factors into
3(9x^3 - 4x) a common factor of three has been taken out.
3x(9x^2 - 4) a common factor of x has been taken out. 3x is not a linear factor.
9x^2 - 4 factors by means of the difference of squares
3x(3x - 2)(3x + 2)
The two linear factors are 3x - 2 and 3x + 2
Answer:
Answered is x= 55x
Step-by-step explanation:
13x+10 * 12x+20
soln:
or, 13x+12x+10+20
or, 25x+30
:., therefore, x=55x
