Answer:
Correct answer is: D) a₆ = - 11
Step-by-step explanation:
Given:
a₁ = 9 and aₙ = aₙ₋₁ - 4
We know it is
a₆ = a₅ + d also it is given a₆ = a₅ - 4
When we equate the right sides of equality we get:
a₅ + d = a₅ - 4 => d = - 4
We also know it is a₆ = a₁ + 5 d
Now we will find a₆
a₆ = 9 + 5 (-4) = 9 - 20 = - 11
a₆ = - 11

Answer: Probability deals with predicting future events but statistics involves an analysis of the frequency of past events
Step-by-step explanation:
C=2πr
c=2 x 3.14 x 26mm
answer=163.28mm
F(x)=(x+1)^-1
f(x)=1/(x+1) so
f(x)/g(x) is
1/[(x+1)(x-2)]
Since division by zero approaches infinity, it is not a real value, and is said to be undefined. Division by zero is "not allowed", which just really means that it does not have a real value. So in this case x cannot equal -1 or 2 so the domain is:
All real numbers except -1 or 2...which can be expressed as:
(-oo,-1),(-1,2),(2,+oo)
