Just know that:
n! = n(n-1)!
= n(n-1)(n-2)!
= n(n-1)(n-2)(n-3)!
= ...
Complete question :
Suppose there are n independent trials of an experiment with k > 3 mutually exclusive outcomes, where Pi represents the probability of observing the ith outcome. What would be the formula of an expected count in this situation?
Answer: Ei = nPi
Step-by-step explanation:
Since Pi represents the probability of observing the ith outcome
The number of independent trials n = k>3 :
Expected outcome of each count will be the product of probability of the ith outcome and the number of the corresponding trial.
Hence, Expected count (Ei) = probability of ith count * n
Ei = nPi
Answer:$5408
Step-by-step explanation:
The first company offers a straight commission of 5% of the sales. This means the salary or income is 5% of sales made.
The second company offers a salary of $260 per week plus 4% of the sales. This means salary or income
= $260 +4% of 260
= 260 + (4/100)×260
= 260 +(0.04×260)
=260+10.4 = $270.4
Let x = the amount of sales you would have to sell in a week in order for the straight commission offer to be at least as good
5% of x should be greater than or equal to $270.4
0.05x = 270.4
x = 270.4/0.05 =$5408
The sales should be greater than or equal to $5408
Answer:
first blank = 39
second blank = 28
Step-by-step explanation:
11 + __ + 7 + 28 = 85 = 39 + __ + 11+ 7
since,, four terms add upto form 85 out of which two terms (11 and 7) are common. so, the first blank will be filled with 39 and second blank with 28.
Answer:An absolute value inequality is solved by re-writing it as compound inequality. For example.
|x+1| < 5
Since the value inside the absolute value brackets: (x+1) can be positive or negative, it is re-written as a compound inequality as the example below.
x+1 < 5
x+1 > - 5
solve for the range of values x can be
-6 < x < 4
