It shows that the content of dietary fiber is negatively correlated to the blood cholesterol of college student, as the correlation coefficient is negative. However, the r=-0.45 shows the two factors are lowly correlated (absolute value of r between 0.3 and 0.5)
Answer: false
Step-by-step explanation:
false
Answer:
X= A (Where A is a constant)
Step-by-step explanation:
Equation of y axis is X=0
Here it means that each point on y axis will have the same abcissa which is 0.
Now if you move parallel to the y axis the line will have an equation
X= A ; here A is an constant ( Can be both negative and positive depending on where the line is respect to the y axis)
here it means that each point on that line will have the same abcissa which is equal to a constant.
Let x or y be 0
4x-2y=5
4(0)-2y=5
-2y=5
Divide -2 and 5 by -2.
y=-2.5
4x-2y=5
4x-2(0)=5
4x=5
Divide 4 and 5 by 4.
x=1.25

Answer:
-16
Step-by-step explanation:
distribute the 4: 4x-8=-72
add 8 to both sides: 4x=-64
divide by 4: x+-16
