1.theoretical is not counting the results of the experimentssince there are an equal number of red and black and red, the probblity (theoretical) of picking a black one is 1/3
experimental=number of outcomes happened/total number of tests4 times black, 4 tests, so 4/4 or 100%=experimental proablity
2. experimental considered previous trials and theoretical did not
3. theoretical=(1/4) the trials don't influence each other so1/(4*4)=1/16
The cow will produce 520.25 in one day.
Answer:$0.78
Step-by-step explanation:
Answer:
The first four terms are 3,9,27,81
Step-by-step explanation:
<u>Step :-1</u>
Given first term of sequence is 
Given 'n' t h term is 
.............(1)
here we put n = 2 in equation (1)
..............2
put in equation (2)
put n=3 in equation (1)
put n= 4 in equation (1)
The first four terms of the sequence is
3 , 9, 27 , 81 ....this is geometric sequence
a =3 and ratio term is r =3
For the first problem, when you see expression like that it just means to write it twice, then FOIL it.
(2x-6) (2x-6)
If you don't know what FOIL is let me know and I can further explain it!
This also applies for the second question!
