Answer: 1.5923926292577
Step-by-step explanation: Count, N: 14
Sum, Σx: 49
Mean, μ: 3.5
Variance, σ2: 2.5357142857143
Steps
σ2 =
Σ(xi - μ)2
N
=
(1 - 3.5)2 + ... + (6 - 3.5)2
14
=
35.5
14
= 2.5357142857143
σ = √2.5357142857143
= 1.5923926292577
26c^2 13c^3
---------- / ----------
5c^2 d^1 25d^3
26c^2. 25d^3
---------- • -------------
5c^2 d^1 13c^3
The top simplifies to 2 • 5 • d^2 = 10d^2, and the bottom is c • c = c^2
It would be 10d^2
------------
c^2.
The answer is B
This is because to work it out I just used the options by multiplying each one together, for example, for B, I did 2x+3 * x-1 and I got 2x2+x-3 which means it was correct
F(x)=x (and then plus something, i’m not sure)
Answer:
I got R = -189
