Answer:
3
Step-by-step explanation:
Standard derivation is how much the data varies from the mean
class 2 has a lower derivation, the scores vary less from the mean, being closer
Answer:
Step-by-step explanation:
In an arithmetic sequence, we keep adding/subtracting to get the next term in the sequence.
Therefore, we can make an equation that looks like this:
5k-(2k+1) = 7k+2-5k
We can subtract 2k+1 from 5k, and 5k from 7k+2, because from subtracting the difference would be the same. (common difference of sequence is what we would find)
Now, we just need to simplify.
5k-2k-1 = 2k+2
3k-1=2k+2
Now let's combine like terms, and we get:
k=3

<span>slope formula, which states that m = (y2 -- y1) / (x2 -- x1).</span>
1) y=Mx+b
2) substitute the values: 0= -8x2 + b
3)multiply: 0= -16 +b
4) add 16 to both sides : 16= b
5) b is your y int. Plug in the values y=2x + 16
Answer : y= 2x+ 16
Answer:
8
Step-by-step explanation:
88 ÷ 11 = 8, therefore the answer is 8
