Answer: correlation = positive
the estimated score would be 61
Step-by-step explanation:
it’s right trust me
The ratio you are told means that for every 5 pink salons, you have 7 yellow swans. This means that if you have more, you have to multiply both values. For example, if you had 10 pink salons, then you would have 14 yellow swans because 5 × 2 = 10 so therefore 7 × 2 = 14. In this case, 390 ÷ 5 = 78, so you need to multiply 7 by 78, which gives you 546 yellow swans in total. I hope this helps!
First add both number with x and then add both number with y and then add both numbers which is the answer to both equations and that is called linear combination.
