why are convenience samples are not desirable?
Answer:
The disadvantages: Convenience samples do not produce representative results. If you need to extrapolate to the target population, convenience samples aren't going to get you there. ... Much larger convenience samples are not more accurate than small probability samples.

A large stockpile of used pumps contains 20% that are currently unusable and need to be repaired. A repairman is sent to the stockpile with three repair kits. He selects pumps at random and tests them one at a time. If a pump works, he goes on to the next one. If a pump doesn't work, he uses one of his repair kits on it. Suppose that it takes 10 minutes to test whether a pump works, and 20 minutes to repair a pump that does not work. The expected value and variance of the total time it takes the repairman to use up his three kits are, respectively:____.
Answer:
Expected value = 190
Variance = 4000
Step-by-step explanation:
Let X be the number of the trials until the third success of the bad pump.
This implies that X is a negative binomial distribution having θ = 20% = 0.2.
Now, if for example it will take X trials to use up the three pumps, then the total time is 10 min/trials + extra 10 minutes for the 3 bad pumps
This means the total time is written as;
T = 10X + (10 + 10 + 20)
T = 10X + 40
Mean which is also expected value of X is;
μ_x = 3/0.2 = 15
Variance of X is; σ²_x = 40
Thus;
Mean of T will be;
μ_T = 10μ_x + 40
μ_T = 10(15) + 40
μ_T = 190
Also, variance of T will be;
σ²_T = 10²•σ²_x
σ²_T = 100 × 40
σ²_T = 4000

Nester needs a cover for his circular outdoor pool. The circumference of the cover must be 16 meters. Which quantity is closest to the area of the pool cover measured in square meter?
Answer: 200.96
A - C/r, d = 16 ⇒ r = 8
A = (16π/2) (8)
= 8π (8) = 64π
A = 64 (3.14) ?
64 (3.14) = 200.96

Ally's Fitbit tells her she has completed 73% of her goal for number of steps taken
today. If she has taken 5,840 steps, what is Ally's goal for the day
Answer:
7416.8
Step-by-step explanation:
5,840 x 127%
Since she's 73 percent of the way there, we need to add the last 27 percent as well as put a one in front so it will work.
127%
Because this is not just 7416 steps you should consider rounding it if your teacher asks you to.

A library had a used book sale for 4 days. The library paid $25 for an advertisement each day of the sale and sold each book (b) for $2.00. The expression below represents the amount of money the library raised at the book sale. How much money was raised when 400 books were sold per day?
Answer:
1,982
Step-by-step explanation:
i got It right on edge 2020
The library raised $320,100 when 400 books were sold per day.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Number of days book sale = 4
The library paid for advertisement each day = $25
Cost of each book (b) = $2.00.
The expression represents the amount of money the library raised at the book sale.
= 4(25) + 2b(400)
Now,
Substitute b = 400 into the expression.
= 4(25) + 2(400)(400)
= 4(25) + 320000
= 320100
Therefore,
The library raised $320,100 when 400 books were sold per day.
