Answer:
last one
Step-by-step explanation:
by=c-ax
b=(c-ax)/y
b=c/y-(a/y)x
The correlation coefficient for the data in the table is A. –0.993
<h3>Calculations and Parameters:</h3>
Using this formula:
We would use x and y to represent the unknowns.
n = 4
We have,
- ∑x = 42,
- ∑y = 44.37 ,
- ∑xy = 461.3
- ∑x^2 = 446,
- ∑y^2 = 494
Putting these values in the formula would bring the answer as. A. –0.993

Answer:
true
Step-by-step explanation:
i think
Yes, histograms main purpose to show ranges from a graph. so like lets say you have a problem where you have ranges of different ages like people from 20-29, 30-45, 46-65, 66-85, you would put that on the y axis and the amount of people on the x axis
Answer:
2 solutions (- 4, 4 ) and (- 1, 1 )
Step-by-step explanation:
The solutions are at the points of intersection of the straight line and the curve.
There are 2 points of intersection , thus 2 solutions
The points of intersection are (- 4, 4 ) and (- 1, 1 ) ← solutions
