A scatter plot is a type of graphical representation. The plot shows the negative relationship as the decrease in the outside temperature increases the bill. Thus, option d is accurate.
<h3>What is a negative correlation?</h3>
A negative correlation in a scatter plot is an inverse relationship that is seen between the two variables of the data. When one variable of the plot increases the other gets decreased and vice versa.
In the case between the temperature and the bill, the decrease in the temperature (cold) increases the heating bill as the heaters will be used more.
Therefore, option d decrease in the temperature increases the heating bill.

Answer:
20 pastries
Explanation:
It is a system of equations.
1. write equations:
2c+3p=120
c+p=50
2. cancel out a variable
2c+3p=120
-2(c+p=50) ---------- -2c+-2p= -100
3. solve for p
p=20
Answer:
C. the truck driver
Explanation:
Since the driver is moving at the same speed, the bulldozer would hyopthetically not seem to be moving to him.
Answer:
In the first equation x=4 or x=-3
In the second equation x=-4 or x=3
Explanation:
The first equation x^2 − x − 12 can be factorized as follows:
x^2-4x+3x-12
x(x-4)+3(x-4)
x-4=0 or x+3=0
x=4 or x=-3
It is noteworthy that -x was rewritten as -4x+3x in order to solve the equation
The second equation x^2 + x − 12 can be factorized as below:
x^2+4x-3x-12
x(x+4)-3(x+4)
x+4=0 or x-3=0
x=-4 or x=3
It is noteworthy that +x was rewritten as 4x-3x in order to solve the equation
Answer:
The first of the basic laws of geometric optics is the law of rectilinear propagation of light. It reads: in an optically homogeneous medium the ray of light propagates in a direction.
