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:
10.25641...% or 10.3%
Step-by-step explanation:
(86/78)/78 = 8/78
8/78 * 100 = 400/39 = 10.25641...%
5/6 is .83333333 it is closer to 1
Y=2, put -4y in for do to the second equation, and then it's technically 5-4 so then you have 1y=2 then you move the 1 to the other side by dividing 2 by 1.
Answer: 7 3/4 - 2/25 = 767/100 = 7 67/100 = 7.67
Step-by-step explanation:
Conversion a mixed number 7 3/4
to a improper fraction: 7 3/4 = 7 3/4 = 7 · 4 + 3/4= 28 + 3/4 = 31/4
To find a new numerator:
a) Multiply the whole number 7 by the denominator 4. Whole number 7 equally 7 * 4/4 = 28/4
b) Add the answer from previous step 28 to the numerator 3. New numerator is 28 + 3 = 31
c) Write a previous answer (new numerator 31) over the denominator 4.
Seven and three quarters is thirty-one quarters
Subtract: 31/4 - 2/25= 31 · 25/4 · 25 - 2 · 4/25 · 4 = 775/100 - 8/100 = 775 - 8/
100 = 767/100
