Answer:
Expected winnings for one spin = 0.1
Step-by-step explanation:
Expected Value = Sum of [(Probability of X)(Value of X)]
E(X) = Σ [P(X).X]
Two Events : X = +68 , P(X) = 1/38 and X = -2 , P(X) = 37/38
E(X) = [(68) (1/38)] + [(-2)(37/38)]
[(68)(0.03)] + [(-2)(0.97)]
= 2.04 - 1.94
= 0.1
Answer: False
Step-by-step explanation:
4x - (5y) 2 = 64x - (5y) 2 = 6
Identify the variables:
4x, 5y, 64x
So, it would actually be:
4, 5, and 64
Answer:
Step-by-step explanation:
-14 is an integer
We can also tell as rational number
as -14 can be written in the form p/q, ie -14/1
Answer:
152
Step-by-step explanation:
Since the measure of angle XYZ is 76 degrees, we know that the measure of XYZ would be twice the amount of the angle measurement due to the square root theorem. In this case 76 times 2 or 76 plus 76 equals 152 degrees. 152 degrees is your final answer.
1981+25
Since she was born in the year 1981, and her son was born 25 years later so you add 25
