A correlation coefficient is a numerical index that reflects the relationship between two variables.
What is the correlation coefficient?The correlation coefficient helps us to know how strong is the relation between two variables. Its value is always between +1 to -1, where, the numerical value shows how strong is the relation between them and, the '+' or '-' sign shows whether the relationship is positive or negative.
1 indicates a strong positive relationship.-1 indicates a strong negative relationship.A result of zero indicates no relationship at all, therefore, an independent variable.The given blank in the sentence can be filled with two variables.
Hence, A correlation coefficient is a numerical index that reflects the relationship between two variables.

Lisa’s kitchen is 6. 5 m wide and the perimeter is 29. 6 m and rectangular in shape.
Calculate the length of her kitchen.
m
ANSWER: 8.3
EXPLANATION :perimeter= (length + width)2
29.6 m = ( length+6.5)2
29.6 = 2l + 13
29.6 Subtract 13 = 2 lengths
16.6÷2 =2l ÷2
length = 8.3
James has6 7/12 cups of flour. He uses 2 5/12 cups to bake some cakes. He uses another 2 8/12 cups to bake some cookies.
How many cups of flour does James have left? Someone please help me i need this asap! <3
Answer:
I believe the answer would be 3/2 or 1 1/2
Step-by-step explanation:
This is how I did it
6 7/12 - 2 5/12 = 4 1/6
Then,
4 1/6 - 2 8/12 = 1 1/2
In decimal form, it'll be 1.5

What is the axis of symmetry of the graph of f(x)=−2x²+8x−2?
For the given parabola, the axis of symmetry is x = 2.
How to get the axis of symmetry?
For any given parabola, we define the axis of symmetry as a line that divides the parabola in two equal halves.
For a regular parabola, we define the axis of symmetry as:
x = h
Where h is the x-component of the vertex.
Remember that for the general parabola:
y = a*x^2 + b*x + c
The x-value of the vertex is:
h = -b/(2a)
Then for the function:
f(x)=−2x²+8x−2
We get:
h = -8/(2*-2) = 2
Then the axis of symmetry is x = 2.

Chen uses these digit cards.
5,6,9
She makes a 2-digit number and a 1-digit number.
She multiplies them together.
Her answer is a multiple of 10
What could Chens multiplication be?
_ _X_
Answer:
95 x 6
or 96 x 5
Step-by-step explanation:
Solve by logicIf you examine the three numbers, you will see that 5 is the only factor of 10.
If we multiply 5 by an even number, we get a multiple of 10.
If we multiply 5 by an odd number, we get a multiple of 5.
Therefore, the 1-digit number must be 5 or 6, and the last digit of the 2-digit number must be 6 or 5.
This means that the first digit of the 2-digit number has to be 9.
So the options are: 95 x 6 and 96 x 5
Proof56 x 9 = 504
59 x 6 = 354
65 x 9 = 585
69 x 5 = 345
95 x 6 = 570
96 x 5 = 480

Answer:
a. 2 7/9 miles
b. 21.6 minutes
c. 8 1/3 miles
Step-by-step explanation:
The rate at which Catlin runs can be determined from the graph by finding the coordinates of a grid point that lies on the line. The line goes through the origin, so the relationship between time and distance is proportional.
We see that the point (miles, minutes) = (1 2/3, 12) lies on the graph, so the contant of proportionality is ...
k = y/x = 12/(5/3) = 36/5 = 7.2 . . . . minutes/mile
__
a.The proportion can be written ...
distance/(20 minutes) = (1 mile)/(7.2 minutes)
distance = (20/7.2) miles = 2 7/9 miles
Catlin will run 2 7/9 miles in 20 minutes
__
b.The proportion can be written ...
time/(3 miles) = (7.2 minutes)/(1 mile)
time = (3)(7.2 minutes) = 21.6 minutes
Catlin was running 21.6 minutes
__
c.In 1 hour, Catlin will run 3 times as far as in 20 minutes. Using the result from part A, we find ...
3(2 7/9 miles) = 8 1/3 miles 8 1/3 miles
Catlin will run 8 1/3 miles in one hour.
_____
Additional comment
Once we have a relationship between minutes and miles, we can write proportions with either of those numbers in the numerator or denominator. We find it convenient to put the unknown value in the numerator of a proportion, which is why the ratios are written differently in the different parts of the problem.
1. Mr. Samuel had 13 notes in his wallet. They consist of $1. $5 and $10 notes. The total amount of the notes adds up to $93. How many $10 notes are there in his wallet?
Answer:
8 $10 notes
Step-by-step explanation:
I started by working it backwards. $93-$3 equals $90. So we have three of our 13 notes. We need ten more. Well the most $10 notes we can have is 8. if we had 8 $10 notes that would give us $80. $90-$80=10. We can take ten and divide it by five so we have 2 $5 notes.
So in total he would have 8 $10 notes, 2 $5 notes, and $3 one dollar notes which adds up to 13 notes

A function f is odd and f(x)=x^2 for all x>0. Sketch the graph of this function and then write the rule of this function as a single formula.
We will see that we have a piecewise function:
f(x) = x^2 for x > 0.f(x) = -x^2 for x ≤ 0.The graph can be seen at the end.
What is an odd function?
A function is odd when f(-x) = -f(x) for all the values of x in the domain of the function.
In this case, we know that:
f(x) = x^2 for x > 0.
Then, for the negative range, the sign must change (but the quadratic function is even). Then we define the function in the negative range as:
f(x) = -x^2 for x ≤ 0.
This is the odd function (a piecewise function) for the whole domain:
f(x) = x^2 for x > 0.f(x) = -x^2 for x ≤ 0.The graph of the piecewise function can be seen below.

Answer:
[tex]f(x) =\frac{x^3}{|x|}[/tex]
Step-by-step explanation:
Being an odd function means that [tex]f(-x) = -f(x)[/tex].
Graphically, it means the function will be symmetric across the origin.
So, the graph will have to look like the shown graph.
This graph looks quite similar to the graph [tex]f(x) = x^3[/tex], so we can use that as our parent function.
To get the graph to equal [tex]x^2[/tex] for x>0, we must divide [tex]x^3[/tex] by x.
However, this will simply result in the function [tex]f(x) = x^2[/tex].
If we divide by the absolute value of x however, the graph will look as desired.

The LaSalle High School senior class raised funds for an end of the year cruise getaway. The city gave
them a special package for the port fees and taxes - a flat fee of $1,500 for the entire class's port fees
and taxes. It costs $367 per student to board the cruise. If your class raised $16, 600, how many students
can attend?
Answer:
41 Students
Step-by-step explanation:
Step the equation up as 367x+1500=16600. You want to subtract 1500 from both sides and you get 15100. Divide 15100 by 367 for how much it costs for each student and you get 41.1444141689 you want to round down because you can't have a part of a student.

The slope equals the rise divided by the run:
Step-by-step explanation:
You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.
