Answer:
B/ it represents a perfectly linear positive correlation between x and y
Step-by-step explanation:
correlation
of -1.0 indicates a perfect negative correlation, and a correlation of 1.0 indicates a perfect positive correlation.
The correlation coefficient for the data represents a perfectly linear positive correlation between x and y.
What is a perfectly linear positive correlation?It means the variable should be shifted together by having the similar percentage and the direction.
Here it shows the direct relationship between two variables it can be anything like the demand for the product, and the price of the product.
hence, The correlation coefficient for the data represents a perfectly linear positive correlation between x and y.

Answer:
0.98
Step-by-step explanation:
0.98 would be the most logical answer. If there is a 0.2 percent chance, it has a 20% chance of happening, which isn't likely. If there is a 0.5 percent chance, it is split so it can't really be likely or unlikely. Whereas having a 0.98 percent chance means there's a 98% of it happening.
Solve |3x + 9| + 6 = 6
A) x = 3
B) No solutions
C) x = –3
D) x = 3 or x = –3
Answers
Answer:
D
Step-by-step explanation:
3x+9+6=6
step 1 combine like terms
9+6=15
now we have
3x+15=6
step 2 subtract each side by 15
15-15 cancels out
6-15=-9
now we have
3x=-9
step 3 divide each side by 3
3/3 cancels out
-9/3=-3
x=-3
The reason it can also be -3 is because I I means absolute value and the absolute value of negative 3 is positive 3

14+7=21
Answer:
x=1
Step-by-step explanation:
given
21=14+7x
our objective is to get the variable (x) by itself
To do so we use inverse operations
so to get rid of the 14 we subtract 14 but whatever you do to one side you have to do to the other so we subtract each side by 14
14-14 cancels out
21-14=7
now we have
7x=7
now we want to get rid of the 7
to do so we divide by 7 but remember whatever we do to one side we have to do to the other side so we divide each side by 7
7/7 cancels out
7/7=1
we're left with x=1

The figure of a triangle DEF.
To find:
The coordinate of image of given triangle after reflection over y-axis.
Solution:
The vertices of given triangle are D(1,4), E(4,3), F(2,0).
If a figure is reflected over the y-axis, then the rule of reflection is
[tex](x,y)\to (-x,y)[/tex]
Using this rule, we get
[tex]D(1,4)\to D'(-1,4)[/tex]
[tex]E(4,3)\to E'(-4,3)[/tex]
[tex]F(2,0)\to F'(-2,0)[/tex]
Therefore, the coordinates of image are D'(-1,4), E'(-4,3) and F'(-2,0).
