Answer:
x = 8/11
Step-by-step explanation:
5x - 4 = -6x + 4
Collect like terms
5x + 6x = 4 + 4
11x = 8
x = 8/11
Answer:
Step-by-step explanation:
If the number of defects in poured metal follows a Poisson distribution, the probability that x defects occurs is:
Where x is bigger or equal to zero and m is the average. So replacing m by 2, we get that the probability is equal to:
Finally, the probability that there will be at least three defects in a randomly selected cubic millimeter of this metal is equal to:
Where
So, P(0), P(1) and P(2) are equal to:
Finally, and are equal to:
Answer:
at least 81 times. playing 80 times would mean you played exactly what it's worth, 7*80=560, so playing 81 times means you pocket a difference of 7 dollars. if you're going to be playing at least 81 times yearly, go for the membership..
The answer is to this problem is 5/8 or 0.625
Answer:
1,700
Step-by-step explanation:
The computation of the initial value of the computer is shown below:
Let us assume the value of a certain computer in the first year is X
In the second year, it is
In the third year, it is
In the fourth year, it is
Now it is given that after 3 years, the value of the computer is = 425 i.e equal to
So, X = 1,700
Hence, the initial value of the computer is 1,700
