The residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.
<h3>What is residual value?</h3>
The residual value is the estimated value which is calculated for the end of the lease terms for a fixed asset. 
Points and their residual values are shown in the table. A 3-column table with 5 rows. 
-   x                               1,     2,     3,     4,     5.
-   y                               2,   3.5,   5,    6.1,    8.
- Residual Value       -0.4, 0.7,  -0.2, -0.6   0
The simple regression line can be represented as,

Here α is the constant, β is the slope and <em>e </em>is the residue. 
The point which is farthest from the best fit of the line is 3.5. At y=3.5, the value of residue is 0.7.
Thus, the residual value, which is the farthest from the line of best fit for the table which shows points and their residual values, is 0.7.

Answer:
   B:  2⁷-1 = 127
Step-by-step explanation:
A Mersenne prime is a prime of the form 2^n -1, where n is also a prime.
Among the answer choices, neither 90=2·3²·5 nor 15=3·5 is prime. Both 2⁷-1 = 127 and 2¹¹-1 = 2047 are of the right form, but 2047 = 23·89 is a composite number.
   2⁷-1 = 127 is a Mersenne prime
