What is the mean, median, and mode of 6,2,3,4,4,2,8,5,2
pogonyaev
Mean: 4
median: 4
mode: 2
range: 6
101 = 100 + 1
102 = 100 + 2
103 = 100 + 3
and so on, and
99 = 100 - 1
98 = 100 - 2
97 = 100 - 3
and so on. Then the -th term of the sum, where , is
We want to compute the sum,
We have
but notice that in the last sum, we're just adding the same number of 1s and -1s together, so its value is 0 and
In case you're not familiar with the formula for the sum of consecutive squares, we can derive it here. Recall that
Notice that
and that
Then
Now consider the cases where is either odd or even.
- If is odd, we can write , where . Then
- If is even, we can write and so
The original sum is obtained by adding the odd- and even-indexed sums together:
9514 1404 393
Answer:
y = 7
Step-by-step explanation:
The y-axis is the vertical line x=0. A perpendicular line will be a horizontal line that will have an equation of the form ...
y = constant
In order for that line to go through a point with y-coordinate 7, the line must be ...
y = 7
O,-12
3.-3
hope this helps
