The answer is step 2, he should have subtracted the 9 or added the six when he was moving x's...
Answer:
x = -17
Step-by-step explanation:
Divide both sides by two and get:
x = -17
Answer:
y= -40
Step-by-step explanation:
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.
Answer:
Step-by-step explanation:
The answer is "Impossible to solve" , because there is no rule for function at point x = 7 . The given function has domain ( - ∞ , 2 ) ∪ { 2 } ∪ ( 2 , 7 ) ⇒ 7 is not a part of domain!!!
