Answer:
1/25
Step-by-step explanation:
5^-2
We know that a^ -b = 1/ a^b
5^-2 = 1/ 5^2
= 1/25
Answer:
Common difference is 13 for this arithmetic sequence 29,42,55,68,...
Step-by-step explanation:
Given the arithmetic sequence 29,42,55,68,...
we have to find the common difference of the above sequence.
Common difference of arithmetic sequence is the difference between two successive terms. Therefore, to find common difference we take any pair of successive numbers, and subtract.
Common difference,
d=42-29=13
d=55-42=13
d=68-55=13
Hence, the difference between two successive terms is 3
∴ Common difference is 13

Answer:
64/729
or 0.088 to 3 decimal places.
Step-by-step explanation:
The probability of no 2 and no 3 on one throw of the dices = 4/6 = 2/3.
For 6 rolls we multiply this 6 times because each throw is independent.
The answer is (2/3)^6
= 64/729
or 0.088 to 3 decimal places.
I don't know if this is right but i think the answer is 11 because as the number of people in the group goes up the price keeps decreasing by 3 so I made a table to see the difference...
1=42
8=39
9=36
10=33
11=30
