Answer:
um whats the question
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
First of all,
- if the line goes Upward (from left to right), it is sloping upward and the correlation coefficient would be POSITIVE.
- If the line goes Downward (from left to right), it is sloping downward and the correlation coefficient would be NEGATIVE.
Since, from the graph we can see that the line is sloping upward, we know the correlation coefficient would be POSITIVE, so we can immediately eliminate choices A & B.
Now, the closer the correlation coefficient value is to 0, the less steep the line is. The closer it is to 1, the more steeper it is.
Looking at the graph, it isn't that flat, it is quite steep. So the correlation coefficient would be 0.8, NOT 0.1
So, answer choice C is right.
D. 69
Break up the figure then multiply the numbers.
9 x 5=45.
4 x 6=24.
Then add.
45+24=69
Let the initial money be x so by question,
3x/5 +1x/5+1200=x
or, 1200= x - 4x/5
or, 1200 = 1x/5
or, 6000= x
hence the initial money was 6000$
-4 + 6√2 and -4 -6√2 are the two numbers that will add up to -8, and will multiply to -56.
