Answer:

Step-by-step explanation:
Given
x -
= 9 ← square both sides
(x -
)² = 9²
x² - 2 +
= 81 ( add 2 to both sides )
x² +
= 83
Now
(x +
)² = x² +
+ 2, thus
x² +
= 83 + 2 = 85
(x +
)²= 85 ( take the square root of both sides)
x +
=

Answer:
0.8745.
Step-by-step explanation:
P(success) = 0.09 and P(failure) = 1 - 0.09 = 0.91.
P( at least 6 failures) = P( less than 2 successes)
= 7C0 (0.09)^0 (0.91)^7 + 7C1 (0.09)(0.91)^6
= 0.5168 + 0.3577
= 0.8745.
