Which could be a conditional relative frequency table ???
user100 [1]

Answer:

The table that represents the conditional relative frequency is:

                           A                B                Total

C                        0.25           0.75             1.0

D                        0.35           0.65             1.0

Total                 0.30           0.70              1.0

Step-by-step explanation:

We know that a conditional relative frequency table is one:

In which the entries in each row is divided by the row total .

                        OR

In which the entries in each column is divided by the column total.

i.e. the frequency or quantity of an item is being compared either to row or to the column total.

Hence, from the given options, the table that represent the conditional relative frequency is:

                           A                B                Total

C                        0.25           0.75             1.0

D                        0.35           0.65             1.0

Total                 0.30           0.70              1.0

In a geometric sequence, A1 = 0.3 and r=3.Find A12, to the nearest integer
soldi70 [24.7K]

Step-by-step explanation:

We have,

First terms of geometric sequence, a = 0.3

Common ratio, r = 3

It is required to find the 12th term of a GP. The formula of the nth term is given by :

T_n=ar^{n-1}

Here, n =12

So,

T_{12}=0.3\times 3^{12-1}\\\\T_{12}=0.3\times 3^{11}\\\\T_{12}=53144.1

or

T_{12}=53144

So, the 12th term of the GP is 53144.
