No correlation
A scatterplot is used to represent a correlation between two variables. There are two types of correlations: positive and negative. Variables that are positively correlated move in the same direction, while variables that are negatively correlated move in opposite directions.
Answer: A: V is an acute angle, so it is less than 90 degrees. I would say it's around 45 degrees.
B: K is also an acute angle, but it is fairly close to being 90 degrees, so I'd say around 80 degrees.
C: Q is an obtuse angle, so it is over 90 degrees but less than 180 degrees. I would say it's around 110 degrees.
D: Y is an obtuse angle. It is very close to 180 degrees. I would say it's around 160 degrees.
Step-by-step explanation:
The expanded form of 584 is:
584 = 500 + 80 + 4
Therefore:
3 · 584 = 3 · ( 500 + 80 + 4 )
Then we will use Distributive property : we can multiply a sum by muptiplying each addend separately and then add the products.
3 · 500 + 3 · 80 + 3 · 4 = 1,500 + 240 + 12 = 1,752
Finally: 3 · 584 = 1,752.
Here is a saying 5 and above give it a shove (round up) 4 and below go down low (round down). In your case you would leave it the same, because when rounding you would round to the nearest 10th.
Example:
54 would round down to 50 and 55 would be rounded up to 60.
