Answer:
0.783
Step-by-step explanation:
To find first r and then r square for the data
correlation coefficient of x and y = Cov (x,y)/std dev x * std dev Y
Cov (x,y) = E(xy) -E(x)E(y)
Hence calculations would be as follows:
x y xy
1 2 2
2 10 20
5 5 25
7 18 126
10 25 250
Mean 5 12 84.6
Cov E(xy)-E(x)E(y) 24.6
r 0.884640297
r^2 0.782588454
so answre is 0.783 after rounding off.
Answer:
5 L
Step-by-step explanation:
As given in question,
1 L can fill 4.2 cups.
So, 1 cup can hold 
L of fluid.
Therefore,
21 cups can hold = × 21
= 5 L
So, there is 5 L of fluid in 21 cups.
