Answer:
The probability is 0.2650
Step-by-step explanation:
Let's start assuming that men and women come in at the same rate.
Let's define the following random variables :
X : ''Number of people that enter a drugstore''
M : ''Number of men that enter a drugstore''
W : ''Number of women that enter a drugstore''
The number of people will be the number of men plus the number of women
⇒
X = M + W
We are also assuming that M and W are independent random variables.
X ~ Po (10)
M ~ Po (λ1)
W ~ Po (λ2)
λ1 = λ2 because we assumed that men and women come in at the same rate.
λ1 = λ2 = λ
λ1 + λ2 = λ + λ ⇒ 2λ = 10 ⇒ λ = 5
M ~ Po (5)
W ~ Po (5)
Because X is the sum of two independent Poisson random variables.
We are looking for :
Because we assume independence.
because is a Poisson random variable with λ = 5
The first commision would be $60, on top of the $3000 to buy the shares. The second commision would be $45, with a $4500 sale point. So $4500 - $3105 = $1395 is the profit.
Answer:
We have;
Hours (h), Total cost C
1, 5*1 + 10 = $15
2, 5*2 + 10 = $20
3, 5*3 + 10 = $25
4, 5*4 + 10 = $30
5, 5*5 + 10 = $35
Step-by-step explanation:
The given parameters are;
Kevin's fixed charge for lawn cutting = $10
Kevin's charge for lawn cutting per hour = $5
The total cost, C, for cutting lawn cutting by Kevin is C = 5h + 10
2.4 ÷ 0.3 = 8
Scale factor = 8
8 = positive integer
Therefore, it is an enlargement
A positive correlation means sales are rising because of advertising
the steeper the chart the more money is being made, so the owner would be happier with a steeper slope
