The correlation coefficient is a number between zero and 1 and the answer is <u>false</u>
And that is because the correlation coefficient is a number between -1 and one. A positive correlation coefficient means that two variables are positively correlated or move in the same direction. Plus one means perfect like full correlation, zero means there is no correlation whatsoever.
And a negative correlation means that as one variable moves in a positive direction, the other moves in a negative direction, so that is negative correlation, And the correlation of -1 means perfect negative correlation.
<h3>What Is the Correlation Coefficient?</h3>
The correlation coefficient is a statistical measure of the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.
A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation. A correlation of 0.0 shows no linear relationship between the movement of the two variables.

N=n(n−1)÷2
For example there are 12 people he
So
N=12(12–1)÷2=132÷2=66
That's for once but they handshaked after the meeting so
66∗2=132
Hope this helps!

Answer:
37.3
263.5
Explanation:
The scale measures hundreds of units, tens of units, units, and parts of units (1 decimal place.
Scale 1
Hundreds 0 * 100 = 0
Tens: 3 * 10 = 30
Units: 7 * 1 = 7
1/10 unit = 3* 0.1 = 0.3
Total 30 + 7 + 0.3 = 37.3
Scale 2
Hundreds 2 * 100 = 200
Tens: 6 * 10 = 60
Units: 3 * 1 = 3
1/10 unit = 5* 0.1 = 0.5
Total = 200 + 60 + 3 + 0.5 = 263.5
Answer:
b
d
a
c
Explanation:
More carbons in longest chain = higher BP
D has a BP of 0.8
A has a BP -0.5
C is the lowest because the more branched it is the lower BP
The percent composition of W in WC is 93.868 %.
MM of WC = 183.84 u + 12.01 u = 195.85 u
% W = Mass of W/Mass of WC × 100 % = 183.84 u/195.85 u × 100 %
= 93.868 %.
