Answer:
Step-by-step explanation:
Given that points scored is the dependent variable Y and Number of people attending the game is the independent variable is independent variable x
The correlation coefficient, slope and intercept are calculated as shown below:
x y
378 54
350 57
320 59
478 80
451 82
250 75
489 73
451 53
410 67
215 78
113 67
250 56
450 85
489 101
472 99
Mean 371.0666667 72.4
std dev 117.5138087 15.42632259
covariance 667.5733333
r 0.394558035
Slope 3.005642934
Intercept 153.4581182
y = 3.006x+153.46 is the regression line.
Corre = 0.3945 (weak positive)
X/2 = 68.2
Given that Colin’s number is X, he divided it by 2. Hence it will be x/2 =68.2. Hope this helps! :)
<span>4c-6+3c=-34
Add 3c to 4c
7c-6=-34
Add 6 to both sides
7c=-28
Divide 7 on both sides
Final Answer: c=-4</span>
