Answer:
Question A is satistical
Step-by-step explanation:
a satistical question is a question that you can answer by collecting data
sence you will need the temperatures for December for each 10 years that would be data unlike question B.
Question B: you will need to collect the warmest temperature in December from the past 10 years.
The correct answer is that the variability is 2.0 times as large.
In the first set, the MAD is 1.2.
In the second set, the MAD is 0.6.
Dividing 1.2 by 0.6 gives us a factor of 2.
All three series converge, so the answer is D.
The common ratios for each sequence are (I) -1/9, (II) -1/10, and (III) -1/3.
Consider a geometric sequence with the first term a and common ratio |r| < 1. Then the n-th partial sum (the sum of the first n terms) of the sequence is
Multiply both sides by r :
Subtract the latter sum from the first, which eliminates all but the first and last terms:
Solve for :
Then as gets arbitrarily large, the term will converge to 0, leaving us with
So the given series converge to
(I) -243/(1 + 1/9) = -2187/10
(II) -1.1/(1 + 1/10) = -1
(III) 27/(1 + 1/3) = 18
We can solve this problem in different ways:
0. Statement: As angle 1 and 3 are vertical angles, and angle 1, 5, 4 form a straigth angle, so angle 2 and (algle 4 + angle 5) are vertcal angles too.
