Cost Number
9 85
2 52
3 55
4 68
2 67
5 86
9 83
10 73
Value of linear correlation coefficient R is 0.70772136
or
= 0.708
For clarification look at the spreadsheet which has been attached and uses the following steps which are as follows
Step 1

Answer:
y=2x+5
Step-by-step explanation:
−8x+4y=20
Step 1: Add 8x to both sides.
−8x+4y+8x=20+8x
4y=8x+20
Step 2: Divide both sides by 4.
4y4=8x+204
y=2x+5
Answer:
C. 60,000
Step-by-step explanation:
<u>Given</u>
- 24,000 fans attended a football match
- three times as many bought tickets
- one-sixth of them cancelled their tickets
<u>Three times as many bought tickets</u>
24,000 * 3 = 72,000
<u>one-sixth of them cancelled their tickets</u>
72,000 * 1/6 = 12,000
<u>Subtract</u>
72,000 - 12,000 = 60,000
<u>Answer</u>
