Multiplying ,you get 18x^2+21x-24x-28. You simplify to get:
18x^2-3x-28.
Answer:
- strong negative linear correlation
- -0.986
Step-by-step explanation:
You need to notice that when altitude goes up, temperature goes down. That means the correlation is negative.
The table shows the temperature decrease to be monotonic (nowhere does it go up when altitude increases), so the correlation is strong.
The strong negative correlation number available to you is -0.986.
___
If you want confirmation, you can put the numbers into your favorite graphing calculator and tell it to compute the correlation for you.
15 /6÷ 5/6
when we divide fractions we do the reciprocal of the second number that is of
5/6 = 6/5 and then multiply it by the first number
15/6 x 6/5
