Answer:
-0.20
Step-by-step explanation:
Given the data:
Age at auction (x) ____price sold (y)
391
51
32
84
47
104
88
43
470
51
Y:
76.9
95.4
86.3
49.3
80
57
47.8
80
70
86.9
General formula for a simple linear regression :
y = ab + c
Where ;
y = predicted variable ; a = slope / gradient
b = predictor / independent variable ; c = intercept
From the result obtained from the calculator :
y = -0.01246X + 74.65552
Correlation Coefficient is used to measure the strength of relationship between linear variables.
The regression Coefficient obtained is - 0.20
This shows that there is a weak negative correlation between the age at auction and the price at which painting is sold. This is because the negative sign means that value of y decreases as x increases or vice versa, however, due to a correlation vale which is closer to 0 than 1 or - 1, we can conclude that the negative relationship between the variables is weak.

Answer:
(11, 13)
Step-by-step explanation:
First Equation: x+y=24
Second Equation: y=x+2
x + (x + 2) = 24
2x + 2 - 2 = 24 - 2
2x/2 = 22/2
x = 11
y = (11) + 2
y = 13
Therefore, the solution to the system is (11, 13)
Answer:
The ratio of candidate 2's votes to candidate 1's votes was 24:8
The ratio of candidate 1's votes to candidate 2's votes was 1:3
Step-by-step explanation:
Candidate 1's votes is 8000
Candidate 2's votes 24000
To get the ratio of candidate 2's votes to candidate 1's votes take 24000 : 8000 divide by 1000 both sides you get 24:8
To get the ratio of candidate 1's votes to candidate 2's votes take 8000 : 24000 divide 8000 both sides you get 1:3
Other ratios whatever you divide the answers is incorrect
