The probability that none of them will be returned is 0.729.
Probability:
Probability refer the possibility of the required event.
The probability of an event is a number between 0 and 1, where 0 indicates impossibility of the event and 1 indicates certainty.
Given,
Aram's fine gems allows a customer to return a diamond tennis bracelet if the return occurs within ten days.
Return percentage of the Bracelet = 10%
And, three (3) tennis bracelets are bought by three (3) different customers.
Now, we need to find the probability that none of them will be returned.
Let R be the event of bracelets sold that are returned.
And R' be the event of bracelet sold but not to be returned.
So,
P(R) = 10%
=> P(R) = 0.10
P(R') = (1 - P(R))
=> P(R') = (1 - 0.10)
=> P(R') = 0.90
Now we need to find the probability that none of them are retuned for 3 customers.
Which is equal to
=> 0.90 x 0.90 x 0.09
=> 0.729

Answer: Ok, but can you tell me what you want me to help you with you just put “ The answer to that question was 43.93 not 43.98” and I don’t understand.
Step-by-step explanation:
Answer: Convenience sample.
Step-by-step explanation:
Convenience sample is also known as grab or accident or opportunity samples. It is a example of non probability sample that involves selecting of subjects because of the proximity, convenience and accessibility a researcher as to them. This type of samples are not reliable for data gathering when it involves a very large sample space, let's say a global audience.
Answer:
The average rate of change of f(x) = x + 6 on [4,9) is 1.
Step-by-step explanation:
Given a function y, the average rate of change S of in an interval will be given by the following equation:
In this problem, we have that:
Interval [4,9]
Continuous function(no denominator or even root), this is why i can consider 9 a part of the interval for the calculation. So
.
So
The average rate of change of f(x) = x + 6 on [4,9) is 1.
Your answer would be 9 feet
81=area
9=base
_=height
and area is base x hight so you divide the base by the area so an equation would be 81=9x then you would flip it around so it would be 9÷81=x
x=9
Hope this helps!!
