Answer:
0.087
Step-by-step explanation:
Given that there were 17 customers at 11:07, probability of having 20 customers in the restaurant at 11:12 am could be computed as:
= Probability of having 3 customers in that 5 minute period. For every minute period, the number of customers coming can be modeled as:
X₅ ~ Poisson (20 (5/60))
X₅ ~ Poisson (1.6667)
Formula for computing probabilities for Poisson is as follows:
P (X=ₓ) = ((<em>e</em>^(-λ)) λˣ)/ₓ!
P(X₅= 3) = ((<em>e</em>^(-λ)) λˣ)/ₓ! = (e^-1.6667)((1.6667²)/3!)
P(X₅= 3) = (2.718^(-1.6667))((2.78)/6)
P(X₅= 3) = (2.718^(-1.6667))0.46
P(X₅= 3) = 0.1889×0.46
P(X₅= 3) = 0.086894
P(X₅= 3) = 0.087
Therefore, the probability of having 20 customers in the restaurant at 11:12 am given that there were 17 customers at 11:07 am is 0.087.
Answer:
2/3
Step-by-step explanation:
If 2/3 · x= 4/9 then 4/9 ÷ 2/3= x
KCF (Keep Change Flip)
Keep 4/9
4/9 ÷ 2/3
Change from division to multiplication
4/9 · 2/3
Flip 2/3 to 3/2
4/9 · 3/2
Multiply 4 · 3= 12
Multiply 9 · 2= 18
Simplify
12 ÷ 6= 2
18 ÷ 6= 3
x=2/3
Answer:
You need to show the graph so i can see numbers, you cant dilate the traingle without knowing where it is on the graph.
Step-by-step explanation:
Each bracelet is $5, this can be represented as 5b. (Where b is number of bracelets)
Each necklace is $8, this can be represented as 8n. (Where n is number of necklaces)
We know that the total money raised needs to be at least $100, but it can also be more than that.
So we know that 8n+5b will be greater than or equal too 100.
8n+5b ≥ 100
