Answer:
Graph 1: perfect negative correlation
Graph 2: modest negative correlation
Graph 3: modest positive correlation
Graph 4: strong positive correlation
Graph 5. weak negative correlation
Step-by-step explanation:
If i'm wrong PLEASE correct me
The graph first is perfect negative correlation, graph second is the modest negative correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
As we know, the coefficient of correlation varies between -1 and +1.
If r = +1 (means the relation between the variable is strong and positive)
If r = -1 (means the relation between the variable is strong but negative)
As we can see in the graph, the line goes down represents the negative correlation and the line goes up represents the positive correlation.
So, we can say:
The first graph is perfect negative correlation.
The second graph is modest negative correlation.
The third graph is modest positive correlation.
The fourth graph is strong positive correlation.
The fifth graph is weak negative correlation.
Thus, the graph first is perfect negative correlation, graph second is the modest negative correlation.

Lines a, b, and c lie on the same coordinate plane. Line a is perpendicular to line b and intersects at (3, 6). Line b is perpendicular to line c, which is the graph of y = 2x + 3.
Write the equations of lines a and b.
Answers
Answer:
The answer is below
Step-by-step explanation:
The equation of a straight line is given as y = mx + b, where m is the slope and b is the y intercept.
Given that the equation of line c is y = 2x + 3, and line b is perpendicular to line c. Two lines are perpendicular if the product of their slope is -1. We can see that the slope of line c is 2, let [tex]m_1[/tex] be the slope of line c, hence:
[tex]2*m_1=-1\\\\m_1=\frac{-1}{2}[/tex]
Also, line b passes through (3, 6), hence the equation of line b is:
[tex]y-y_1=m_1(x-x_1)\\\\y-6=\frac{-1}{2}(x-3)\\\\y-6= \frac{-1}{2}x+\frac{3}{2}\\\\y=\frac{-1}{2}x+ \frac{15}{2}[/tex]
Line b has a slope of -1/2, and is perpendicular to line a, let [tex]m_2[/tex] be the slope of line a, hence:
[tex]\frac{-1}{2} *m_2=-1\\\\m_2=2[/tex]
Also, line a passes through (3, 6), hence the equation of line a is:
[tex]y-y_1=m_1(x-x_1)\\\\y-6=2(x-3)\\\\y-6=2x-6\\\\y=2x[/tex]

Answers
The difference between her best time and her worst time is equal to 0.26 seconds.
What is algebra ?
Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
Jodie has to swim for 100 meters. The four of her times to cover this distance are 22.98 seconds, 23.09 seconds, 23.06 seconds, 22.83 seconds.
Let's find the time per sec to swim at each instances.
So ,
100 meters in 22.98 seconds meant :
= 100 / 22.98
= 4.35 m/sec
Similarly ,
100 meters in 23.09 seconds meant :
= 4.33 m/sec
100 meters in 23.06 seconds meant :
= 4.34 m/sec
100 meters in 22.83 seconds meant :
= 100 / 22.83
= 4.38 m/sec
So , we can find out that Jodie swims distance of 100 meters fastest on speed of 4.38 m/sec in 22.83 seconds and slowest on speed of 4.33 m/sec in 23.09 seconds.
The difference between her best time and her worst time is :
= 23.09 - 22.83
= 0.26 seconds
Therefore , the difference between her best time and her worst time is equal to 0.26 seconds.

Answer:
A. y = -1/4x + 1 1/2
B. The rate of change is losing/decreasing -1/4 (y axis unit) per (x axis unit)
Step-by-step explanation:
A. Your equation is 2x + 8y = 12
so solve this for y like any other other question. Start by subtracting 2x from both sides: 8y = -2x + 12
then divide both sides by 8 to isolate y: y = -2/8x + 12/8
simplify your equation: y = -1/4x + 3/2
turn 3/2 into a mixed fraction: y = -1/4x + 1 1/2
B. The rate of change is the same thing as the slope but you say it with units. I cant see a scenario but you can say something like:
The rate of change is losing/decreasing -1/4 (y axis unit) per (x axis unit)

Answers
Answer:
x = 32, y = 51
Step-by-step explanation:
You know the longest side of ΔTUS is 13m and the longest side of ΔMNP is (2x-y). Thus:
2x - y = 13 --- Equation 1
You know the sum of angles in a triangle is 360°. Two of the angles are given in ΔMNP (142° & 24°) and the remaining angle is (2x-50)°. Thus:
142 + 24 + 2x - 50 = 180
2x + 116 = 180
2x = 180 - 116
2x = 64
x = 64 ÷ 2
x = 32 --- Equation 2
Substitute x = 32 into Equation 1:
2(32) - y = 13
64 - y = 13
-y = 13 - 64
= -51
y = 51 --- Equation 3
Answer:
x = 32, y = 51
Step-by-step explanation:
Since the triangles are congruent then corresponding angles and sides are congruent, then
∠ U = ∠ N and NP = US
Require to find ∠ N
∠ N = 180° - (24 + 142)° ← sum of angles in triangle
= 180° - 166°
= 14°
Thus
2x - 50 = 14 ( add 50 to both sides )
2x = 64 ( divide both sides by 2 )
x = 32
and
NP = US
2x - y = 13 ← substitute x = 32
2(32) - y = 13
64 - y = 13 ( subtract 64 from both sides )
- y = - 51 ( multiply both sides by - 1 )
y = 51

Part 2) The dimensions of this surface are 6 in x 6 in
Part 3) Molly needs to paint 228 square inches
Step-by-step explanation:
The picture of the question in the attached figure
Part 1) Which surface is shared by the two solids?
we know that
The surface that is shared by the two solids is the top of the cube that is the same that the square base of the pyramid
Part 2) What are the dimensions of this surface?
The surface is a square with side length 6 inches
so
The dimensions of this surface are 6 in x 6 in
Part 3) what is the area molly needs to paint?
we know that
The area that Molly needs to paint is equal to the surface area of the cube plus the surface area of the pyramid minus two times the area of the surface that is shared by the two solids
so
therefore
Molly needs to paint 228 square inches
