The expression 3p2 represents the number of ways of:

a. choosing 2 items at a time from a set of 3.

c. arranging, in order, 2

c.Arranging in order 2 from a set of 3.

Step-by-step explanation:

We are given that an expression

Permutation : permutation is an arrangement of of n items when r items taken at a time.

It is represented as

Combination is a selection  of r items at a time out of n items.

It is represented by

Therefore, the given expression represents the number of number of ways  of arranging in order 2 from a set of 3.

c.Arranging in order 2 from a set of 3.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
