Answer:
<DCA and <BCF
Step-by-step explanation:
vertical angles are the opposite angles created by intersecting lines and are congruent. Vertical angles share only a vertex
Taylor series is 
To find the Taylor series for f(x) = ln(x) centering at 9, we need to observe the pattern for the first four derivatives of f(x). From there, we can create a general equation for f(n). Starting with f(x), we have
f(x) = ln(x)

.
.
.
Since we need to have it centered at 9, we must take the value of f(9), and so on.
f(9) = ln(9)

.
.
.
Following the pattern, we can see that for
,
This applies for n ≥ 1, Expressing f(x) in summation, we have

Combining ln2 with the rest of series, we have

I believe the answer is D b/c each input has one output
The 68-95-99.7 rule tells us 68% of the probability is between -1 standard deviation and +1 standard deviation from the mean. So we expect 75% corresponds to slightly more than 1 standard deviation.
Usually the unit normal tables don't report the area between -σ and σ but instead a cumulative probability, the area between -∞ and σ. 75% corresponds to 37.5% in each half so a cumulative probability of 50%+37.5%=87.5%. We look that up in the normal table and get σ=1.15.
So we expect 75% of normally distributed data to fall within μ-1.15σ and μ+1.15σ
That's 288.6 - 1.15(21.2) to 288.6 + 1.15(21.2)
