Two simple statements are connected with a and? youre censtructing the truth table of this compound statement. how many rows does the truth table will have?

4 Rows  

Step-by-step explanation:

Since, the number of input given to the AND gate in terms of simple statement, the output of the AND gate will give output true if both the statements given to the AND gate will true otherwise it will show output false.

Let's see the truth table for the inputs of two statements

Statement 1                  Statement 2            Output

 False                               False                       False

 False                               True                         False

 True                                 False                       False

 True                                 True                         True

As we can see the number of rows in the truth table of an AND gate having two input, will have 4 rows.

1/2*qr*rs

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
