Answer:
When it is small & when the sample has things that are different from the population.
Step-by-step explanation:
A small sample has less chance of accurately reflecting a population & too many variables can also negatively influence the study.
Answer:
Step-by-step explanation:
Your original number to convert is 0.333333. Let's slide the decimal point in this number to the right 1 place(s) (the same number of digits in the number 3).
If we do this, we'll get a 3.333333 (slide the decimal in the 0.333333 right 1 places, you'll get 3.333333).
So what? Well now, we have two numbers with the same repeating decimal parts, 3.333333 and 0.333333.
Now let's just work a little algebra into all of this. Let's call your original number x. And in this case, x = 0.333333. The number with the decimal point slid over can be called 10x, because 10x = 3.333333
10x = 3.33333
-x = 0.333333
---------------------------------------------------------------------------------------------
Now, solving 9x=3 for x by dividing both sides of it by 9, we'll get that x=3/9. And this is your answer.
How is this your answer? Well remember that above, x was originally set equal to 0.333333 via x = 0.333333, and now we have that x is also equal to 3/9, so that means 0.333333 = 3/9..and there's 0.333333 written as a fraction.

Answer:
For the cost from the two methods to be equal, 3,200 books have to be produced
Step-by-step explanation:
In this question, we are asked to calculate the number of books that will be produced for two methods of production having different fixed and variable costs to have the same production cost.
Since the number of books is something we do not know, let’s represent it with a variable called c.
For the first production method, the cost of production will be ; 58,881 + 8.50c
For the second production method, the cost of production will be; 18,081 + 21.25c
Now since they are said to be equal, we proceed to equate both;
58,881 + 8.5c = 18,081 + 21.25c
58,881-18,081 = 21.25c - 8.5c
40,800 = 12.75c
c = 40,800/12.75
c = 3,200 books
Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.
<h3>Calculating the mean.</h3>
Based on the information given, it should be noted that the probability distribution for y will be:
Y 0 1. 2
Probability 0.63. 0.25. 0.12
The mean of Y will be:
= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)
= 0 + 0.25 + 0.25
= 0.49
The variance will be 0.4899. Therefore, the standard deviation will be:
= ✓0.4899
= 0.699
