Answer:
None.
Step-by-step explanation:
5/a - 2 / (1 - a) = 2 (a - 1)
Multiply each term by a(1 - a)(a - 1):
5 (1 - a)(a - 1) - 2a(a - 1) = 2a(1 - a)
5( a - 1 - a^2 + a) - 2a^2 + 2a = 2a - 2a^2
5(-a^2 + 2a - 1) - 2a^2 + 2a = 2a - 2a^2
-5a^2 + 10a - 5 - 2a^2 + 2a - 2a + 2a^2 = 0
-5a^2 + 10a - 5 = 0
-5(a^2 - 2a + 1) = 0
= -5(a - 1)^2 = 0
So a = 1.
But a = 1 cannot be a root because 2/ 1 - a would be 2/0 which is undefined.
Also 2 / (a - 1) is undefined.
Consider this population data set:4, 6, 7, 11, 12, 18, 26, 23, 14, 31, 22, and 12. The values 11, 31, 22, and 12 constitute a ra

Answer:
3.5
Step-by-step explanation:
Find the Mean of the Population Data Set
4 + 6 + 7 + 11 + 12 + 18 + 26 + 23 + 14 + 31 + 22 + 12 = 186
186 ÷ 12 = 15.5
Find the Mean of the Sample Data Set
11 + 31 + 22 + 12 = 76
76 ÷ 4 = 19
Subtract
19 - 15.5 = 3.5
Answer: <em>The sample mean is more than the population mean by 3.5</em>
It cannot be equivalent unless you can divide 5/6 into 4/5 and multiply 4/5 into 5/6, but you can't. You can only add both by one which doesn't make it equivalent in any way
