The correlation coefficient is a number that indicates the direction
and closeness of points of a line of best of fit.
So it tells us two things.
It tells us the direction of the line of best fit
and it tells us the closeness of the points.
Usually, anything between -0.9 and -0.6 has a moderate negative correlation. If you look at this on a graph, you will notice that the points definitely resemble a line so we say it's moderate.
It will be a negative correlation because the slope is negative.
Answer:
and
in interval notation.
Step-by-step explanation:
We have been given a compound inequality
. We are supposed to find the solution of our given inequality.
First of all, we will solve both inequalities separately, then we will combine both solution merging overlapping intervals.



Dividing by negative number, flip the inequality sign:





Dividing by negative number, flip the inequality sign:


Upon merging both intervals, we will get:

Therefore, the solution for our given inequality would be
and
in interval notation.
Answer:
62%
Step-by-step explanation:
31/50 is also equal to 62/100 (if we multiply the numerator and denominator by 2). 62/100 is 62%.
Let's see. We can clarify a few things to make the question easier.
-We bought 10 packs of candy
-M&Ms are $1 per pack
-Twizzlers are $0.5 per pack
We need to find out how many bags of M&Ms we bought by only spending $6.
There are many combinations you can use to get to $6. However, I'm not sure what the format is. For example, you could buy 4 twizzler packs and then use the remaining money to find out how many M&Ms you bought. But this seems to be open to answers. Sorry
Answer:
In y = kx, where k is the constant of proportionality.
