Answer:
commutative property
Step-by-step explanation:
You switched the numbers inside the parenthesis, which in this case is 5 and -5.
Answer:
0.1393 = 13.93% probability that an order of 50 units will have one or more faulty units.
Step-by-step explanation:
Mean for a number of units, which means that the Poisson distribution is used to solve this question.
Poisson Distribution:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given interval.
Mean:
3 defective for 1000, how many for 50?
3 - 1000
- 50
Applying cross multiplication:
What is the probability that an order of 50 units will have one or more faulty units?
This is:
In which
0.1393 = 13.93% probability that an order of 50 units will have one or more faulty units.
The experimental probability of drawing an even number is calculated by adding the ratio between the number of times the even numbers are drawn to the total times the tiles were drawn. So,
(6/65) + (10/65) + (14/65) + (3/65)
= 33/65
~ 0.5977
The exact probability is 33/65 or approximately 0.5977 or 59.77%
Step-by-step explanation:
am-an+bm-bn
m(a+b)-n(a+b)
(m-n)(a-b)
What's the smallest six-digit whole number possible?
It is 100000
try counting, six digits, right? if you even take 1 off from it, it's no longer six digits, so it is the smallest six-digit whole number possible.
what's the greatest 4-digit number?
It should be 9999
try adding 1 to it, it becomes five-digit number.
So, 9999 is the greatest 4-digit whole number possible.
To get a difference, subtraction.
100000 - 9999 = 90001
Just as a tip, for six digit number, 000000 does not work, as it is same as 0
