The answer is C: systematic sampling
Answer: 1
Step-by-step explanation: the probability mass function that defines a possion probability distribution is given below as
P(x=r) = e^-u × u^x/x!
For this question, x = 0 and u = 9.5
Hence we have that
P(x=0) = e^-0 × 9.5^0 / 0!
P(x=0) = 1 × 1/ 1 = 1
Answer:
12 weeks
Step-by-step explanation:
Josiah and kiri are each saving money josiah starts with 100$ in savings accound and adds 5$ per week . Kiri with 40$ in her savings account adds 10$ each week after how weeks Josiah and kiri will have the same amount of money in their savings account
Josiah:
100 + 5w
Kiri:
40 + 10w
Where,
w = number of weeks
After how weeks Josiah and kiri will have the same amount of money in their savings account
Equate the savings of the both of them
100 + 5w = 40 + 10w
100 - 40 = 10w - 5w
60 = 5w
w = 60/5
= 12
w = 12 weeks
Josiah and kiri will have the same amount of money in their savings account after 12 weeks
The answer is the square root of 44
