Answer:
a: positive association, the y point is called a deviation
b: looks like the student scores are positive pattern (well accept for that little guy ..little y...)
Step-by-step explanation:
a reason: if you were to draw a line through those points it would be positive linear correlation and that one plot had nothing to do with the correlation
In part a x represents the correlation and y represents the deviation, and in part b association between students test scores and homework assignment is positive.
Graph is given in relation of test score with student home work assignment. Relationship and association of the graph to be determined.
Correlation implies that one of the subject or value related to other subject or value.
Here, from the graph the sets of value of x is increasing and having positive association. Other side y has only single value in it showing as deviation and nothing else.
Thus, In part a x represents the correlation and y represents the deviation, and in part b association between students test scores and homework assignment is positive.

In order for you to carry a bag on the plane, it must t inside the Carry-on Baggage Check Box.
The Carry-on Baggage Check Box has dimensions of approximately 22" x 14" x 9". Your leather bag has a
height of 18 inches, a depth of 12 inches, and a width of 8 inches. Your canvas bag has a height of
18 inches, a depth of 15 inches, and a width of 10 inches.
1. What is the volume of the Carry-On Baggage Check Box?
2. What is the volume of the leather bag?
3. What is the volume of the canvas bag?
4. Which bag will denitely t into the Check Box? Explain.
Step-by-step explanation:
guessing
volume is always unit cubed
so in this case inches cubed or in^3
so multiply all 3 numbers
carry on is 22×14x9= 2772 in^3
leather is 18×12×8 = 1728 in^3
canvas is 18×15×10 = 2700 in^3 but the depth in ge's canvas 15" in larger than the carry on checklist
so
the leather will definitely fit

Answer:
area = 2184 ft²
Step-by-step explanation:
height² = 60² - 36² = 3600 - 1296 = 2304
height = √2304 = 48
base = 36 + x
x² = 73² - 48² = 5329 - 2304 = 3025
x = √3025 = 55
base = 36 + 55 = 91
area = 1/2(h)(b) = 1/2(48)(91) = 2184 ft²

Use PEMDAS.
P - Parenthesis
E - Exponents
M/D - Multiply/Divide
A/S - Add/subtract
So for this:
Start with parenthesis: (5+16) and (1+3), so 21 and 4
Then exponent: 3^2, which is 3*3 which is 9
Then divide: 21/7 is 3
And then the rest: 3 + 9 - 4. 3+9 is 12, 12-4 is 8, so you're answer is 8.
En una multiplicación, si un factor es un número natural y el otro es un número entero negativo, el producto es siempre menor que cada uno de los factores. Es verdadero o falso
Answer:
Falso.
Step-by-step explanation:
Acá tenemos la proposición:
"En una multiplicación, si un factor es un número natural y el otro es un número entero negativo, el producto es siempre menor que cada uno de los factores."
Primero tratemos de demostrar que esto es falso, para ello debemos encontrar un solo ejemplo en el que la proposición sea falsa.
Elijamos al número 1 como el número natural,
Elijamos -10 como el número entero negativo.
El producto es:
1*-10 = -10
Ahora veamos si el producto es menor que cada uno de los factores.
-10 < 1 ?
Si, -10 es menor que 1.
Ahora veamos con el otro factor:
-10 < - 10?
No, un número no puede ser menor que si mismo.
Entonces el producto no siempre es menor que cada uno de los factores.
Entonces la proposición es falsa.

Answer:
114.24°
Step-by-step explanation:
7(15)+6= 105
3(15)= 45, now we plug it in the formula, [tex]a^{2}+b^{2}=c^{2}[/tex]
[tex]105^{2}+45^{2} = 13050[/tex]
so now we square root it
[tex]\sqrt{13050}[/tex]= 114.24
Step-by-step explanation:
111^2 + 45^2 = 14346
then take the square root of 14346
which is 119.77

5x + 19.95 = 35
Solve x
Answer:
X = 3.01
Step-by-step explanation:
To solve for x, you first need to get x by itself. So you would minus 19.95 from both sides. Which would then be
5x = 15.05
Again x is not by itself so you would divide both sides by 5, the eqation would then be
x = 3.01
Which is the answer. If you want you can double check your work by putting the answer back in the eqaution.
5(3.01) + 19.95 = 35
If the statement is true that means you have the right answer
15.05 + 19.95 = 35
35 = 35
We are correct! Hope this helps with your question and how to do others like it.

Graph y = x2 - 8x + 13
Answer:
Step-by-step explanation:
From the given x^2 - 8x + 13 we can find several points to graph to represent this quadratic function.
The y-intercept is (0, 13) and stems from letting x = 0.
b
The axis of symmetry is x = - -----
2a
-8
Since a = 1 and b = -8, the axis of symmetry is x = - ------- = 4
2(1)
and so the vertex is at (4, 4^2 - 8(4) + 13), or (4, -3)
If you want to go the extra mile, find the roots of the given equation. These are also your x-intercepts. One such intercept is (2. 0).
Plot these points and draw a smooth curve through them.
Hint: the parabolic graph opens up.
As an estimation we are told 5 miles is 8 km.
Convert 55 miles to km
Answer:
88 km.
Step-by-step explanation:
If 5 miles is 8 km,
55 miles is 88 km.
What you need to do is 55/5 = 11.
Then multiply that 11 to 8.
11 * 8 = 88.
Basically, if you are multiplying 5 by 11 to get 55, you need to multiply 8 by 11 to get 88.

13). -2x³ + x² + 1 14). x + 10y - 10z 15). -2x³ + x² + 1
Step-by-step explanation:
13). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² - 3 + 4
= -2x³ + x² + 1
14). (3x + 4y - 3z) - (2x - 6y + 7z)

= x + 10y - 10z
15). (x³ - x² + 4) - (3x³ - 2x² + 3)
= x³ - x² + 4 - 3x³ + 2x² - 3
= x³ - 3x³ - x² + 2x² + 4 - 3
= -2x³ + x² + 1

What is the constant?
What is the coefficient?
What is the variable?
What are the factors of 9x?
Answer:
the constant is 3 the coefficant is y and the varible is a and the factors of 9 are 18 and 27
Step-by-step explanation:
Answer:
The constant is 3
The coefficient is 12
The variables are both A and Y.
Disclaimer: I'm not sure about this next one, but I believe it's right.
9x factors are 3x, 1, and 9x.
If you wanted me to factor it, then it'd be something like 3x(3)
Step-by-step explanation:
A constant is a number that is by itself. Variables can't be constants. In this case, the only number that is by itself, that isn't a variable is 3. Therefore, 3 is the constant.
A coefficient is a number that accompanies the variable. Normally in a math equation, a variable is multiplied by a number. In this case, A is being multiplied by 12, so 12 is the coefficient.
The variable is the letter that represents any number. In this case, there are two variables, A and Y. They both represent numbers that can differ. So, A and Y are the variables.
The factors of 9x are 3x, 3, 1x, 1, 9x, and 9.
9 times 1x is 9x, 9x times 1 is also 9x.
3 times 3x is 9x, and 3x times 3 is again, 9x.
