Step-by-step explanation:
Answer:
1. 10 : 24 = 5 : 12 = 20 : 48 = 40 : 96
2. 2 : 3 : 5 = 4 : 6 : 10 = 8 : 12 : 20
Curl is defined as:

Which can be rewritten as:

This is because C1 lies on the xy plane and thus it's unit vector will be
.
By similar arguments the rest will follow too.
Now, area of each circle will be: 
Therefore, Curl, as per our definition will be:

Thus, Curl=
Which is the required answer.
A null hypothesis is a statement where there is no association between the two groups you're talking about.

e) , f)
Step-by-step explanation:
42+15= 57
If the available options are:
a) 5(8+2)+5(3)=(5x10)+15=50+15=65
b) (3 x 14) + (3 x 5)= 42+15=57
c) (3 x 39) + (3 x 5)=117+15=132
d) 3(39 + 12)=3x51=153
e) 3(14 x 5)=3x70=210
f) 3(14 + 5)=3x19=57
