Step-by-step explanation:
A function can't have the same number more than once, so the answer is A since there are no repeating numbers.
4w-7k=28
Move variable to the right to get -7k=28-4w
Divide both sides by -7
k= -4+4/7w
Answer:
r = 0.99
Very strong positive correlation between x and y
Step-by-step explanation:
Given is a data containing years and the corresponding heights
We have to find the correlation coefficient.
x y
1 2.1
2 3.2
3 6.8
4 7.3
5 11.2
6 12.6
7 13.4
8 15.9
r 0.988670694
Formula for r is
Thus we find that correlation coefficient is 0.988670694
Rounding off to two decimals r = 0.99
Very strong positive correlation between x and y
