Answer:
0.95
Step-by-step explanation:
19/20 as a decimal is 0.95
I put 220 divided 3 and The answer is 7.3
The most likely correlation coefficient for the set of data shown is: -0.21.
<h3>Correlation coefficient</h3>
We would be using CORREL in excel to determine the correlation coefficient by inputting the set data below
X Y
A (1,4)
B (2, 1.5)
C (3,3)
D (4,4)
E (5,2)
Hence:
Correlation coefficient=-0.20801
Correlation coefficient=-0.21 (Approximately)
Therefore the most likely correlation coefficient for the set of data shown is: -0.21.

Answer:
Slope= 2 / 10 = 1 / 5 = 0.2
y-intercept= (0, -4/5) or (0, -0.8)
Step-by-step explanation:
We can easily solve this by assuming a linear equation.
The general form is:
y = m x + b
where y is the price of gas, x is the year, m is the
slope or increase in price every year and b is the y-intercept
We can solve the slope by:
m = (3.25 – 1.75) / (2013 – 2003)
m = 0.15
y = 0.15 x + b
Using any pair data, we get the b:
3.25 = 0.15 (2013) + b
b = -298.7
y = 0.15 x – 298.7
