Answer:
B or C or A or E or D i dont know
Step-by-step explanation:
For a relation to be a function, each input must lead to a UNIQUE output. i.e. the same input must not lead to different outputs which is the case in TABLES A, B and D. Therefore, only table C represents a function.
The third choice is appropriate.
an = 5 - 3(n - 1); all integers n ≥ 1
_____
This equation follows the form for the general term of an arithmetic sequence.
an = a1 + d(n - 1)
where a1 is the first term (corresponding to n=1), and d is the common difference. From the problem statement, a1 = 5 and d = 2 - 5 = -3.
Solution:
We are given:
μ=60
σ=15.9
n=40
Therefore, the z-statistic is 1.19
What you want to do is find out the length of A to C first which is radical(6^2 + 4^2)
Then do the same thing using A to C length and 3 to get AG
