Answer:
can i have branliest and heart with 5 stars i really need it right now.
Step-by-step explanation:
We need to represent the numbers of calls symbolically:
Third evening: x calls
First eve: x-6 calls
Second evening: 3x calls
Find x. Add up these three numbers x, x-6 and 3x and equate your sum to 79:
x+x-6+3x = 79. Then 5x=79+6, or 5x = 85. Thus, x = 17.
17 calls on the 3rd night,
17-6 calls on the 1st night, and
3(17) = 51 calls on the 2nd night.
Check! Add together 17, 11 and 51. Do these add up to 79? Yes.
Answer: d. 0.0213
Step-by-step explanation:
Given : Mean arrival rate 
= 16 customers per hour.
The Poisson distribution formula is given by :-
,where is the mean of the distribution.
If X = the number of customers arrivals , then the probability that in the next hour there will be exactly 9 arrivals will be :-
Hence, the probability that in the next hour there will be exactly 9 arrivals= 0.0213
Therefore , the correct answer is option (d.).
Answer:
1/2 = 3/6 so if
1/2 + 1/6 = 3/6+1/6 = 4/6
to reduce 4/6, divide top and bottom by same number, in this case, 2.
4/6 = 2/3
