Answer:
2, 5, 8, 11
Step-by-step explanation:
F(n) = 3n - 1
put n=1
F(1) = 3(1) - 1 = 2
put n=2
F(2) = 3(2) - 1 = 6 - 1 = 5
put n=3
F(3) = 3(3) - 1 = 9 - 1 = 8
put n=4
F(4) = 3(4) - 1 = 12 - 1 = 11
A= -1
You add the 6a and 5a.
Your equation is then 11a= -11
At this point you divide each side by 11 to get "a" by itself.
Answer:
6.5
Step-by-step explanation:
We can assume that 2 is the smallest integer in the set. That means we would have a minimum of 2 2s. Then the largest integer in the set is 9. Since we can't have more than one 9 (due to the mode of 2), the next largest number we can have is 8. After that would be 7. Then the last digit would be 6. So now the set contains { 2, 2, 6, 7, 8, 9}. To find the median in an even set, we need to take the middle numbers and find the average. In this case, the two numbers are 6 and 7. The average of 6 and 7 is 6.5.
Answer: <em><u>5 11/12</u></em>
Step-by-step explanation:
Since they only walked on Monday, Wednesday and Thursday,
You have to add 3/4 + 1 2/3 + 3 1/2
So, 3/4 + 1 2/3 + 3 1/2 =
3/4 + 2/3 + 1/2 = 1 11/12
1 + 3 = 4
4 + 1 11/12 = 5 11/12
