Answer:The Last One
Step-by-step explanation:
Option (B) an association cannot be determined between the categorical variables because the relative frequencies are similar in value is the correct answer.
What is relative frequency?The relative frequency of an event is defined as the number of times that the event occurs during experimental trials, divided by the total number of trials conducted. The sum of all relative frequencies will be one.
For the given situation,
The relative frequencies are 0.48 and 0.52.
A two-way frequency table can be used to show, analyze, and examine the relationships that exists between two categorical variables.
The two relative frequencies have the values that are similar to (close to) each other. So, there will be no association between the categorical values.
Hence we can conclude that option (B) an association cannot be determined between the categorical variables because the relative frequencies are similar in value is the correct answer.

Answer:
The answer is the first option that states that you can write this expression as [tex]7(\frac{x}{8}) + \frac{3}{4} = -6[/tex]
Step-by-step explanation:
In order to solve this question we will need to know how to factor fractions. In our case we can do the following.
[tex]\frac{7}{8}x = \frac{7x}{8} = 7(\frac{x}{8})[/tex]
So now we since [tex]\frac{7}{8} x= 7(\frac{x}{8} )[/tex] ⇒
⇒ [tex]\frac{7}{8}x + \frac{3}{4} = -6[/tex]
[tex]7(\frac{x}{8}) + \frac{3}{4} = -6[/tex]

Answer:
C.) y = 5/4x - 4
Step-by-step explanation:
Points: (0,-4) and (4,1)
m = y2 - y1/x2 - x1
m = 1 - (-4)/4 - 0
m = 1 + 4/4
m = 5/4
Point: (4,1) (you may choose any points, but I will choose these since they are the easiest to work with)
y - y1 = m(x - x1)
y - 1 = 5/4(x - 4)
y - 1 = 5/4x - 5
y = 5/4x - 5 + 1
y = 5/4x - 4

For nitrogen to be a liquid, its temperature must be within 12.78 °F of –333.22 °F. Which equation can be used to find the maximum and minimum temperatures at which nitrogen is a liquid, x?
The equation that can be used to find the maximum and minimum temperatures is
Answer:
For nitrogen to be a liquid, its temperature must be within 12.78 °F of -333.22 °F. The equation |x + 333.22 | = 12.78 can be used to find x, which represents the maximum and minimum temperatures at which nitrogen is a liquid.

Calculate the average time it took the car to travel 0.25 and 0.50 meters with two washers attached to the pulley. Record the averages, to two decimal places, in Table C of your Student Guide.
What is the average time it took the car to travel 0.25 meters?
seconds
What is the average time it took the car to travel 0.50 meters?
seconds
Answer:
1.92 second at 0.25 meters.
2.61 second at 0.50 meters.
Step-by-step explanation:
the average 2 washers on time travel of:
0.25 m : 1.94 / 1.95 / 1.87 = 1.92 second
0.50 m: 2.69 / 2.72 / 2.42 = 2.61 second
In this exercise we have to calculate the time that a car makes in a certain distance, in this way we find that:
A) In 0.25 meters in 1.92 second.
B) In 0.50 meters in 2.61 seconds.
We know that some information is given in the statement as:
In 0.25 meters the car speeds are: 1.94/ 1.95/ 1.87In 0.50 meters the car speeds are: 2.69 / 2.72 / 2.42Knowing that the formula for calculating time is given by:
[tex]Time= Distance/Speed[/tex]
So we have:
A) [tex](1.94 +1.95 + 1.87)/3= 5.76\\0.25/5.76=1.92 s[/tex]
B) [tex]2.69+ 2.72 + 2.42= 7,83\\0.50/7,83=2,61[/tex]

A rectangle is 3 cm longer than it is wide. The diagonal is 15 cm. Find the dimensions of the rectangle?
Answer:
The length is 12 cm, and the width is 9 cm.
Step-by-step explanation:
The length and width of a rectangle as legs form a right triangle with the diagonal of the triangle as the hypotenuse.
We can use the Pythagorean theorem to write an equation.
Let the width = w = leg a
The length = w + 3 = leg b
The diagonal = the hypotenuse = 12 = c
a^2 + b^2 = c^2
w^2 + (w + 3)^2 = 15^2
w^2 + w^2 + 6w + 9 = 225
2w^2 + 6w - 216 = 0
w^2 + 3w - 108 = 0
(w + 12)(w - 9) = 0
w + 12 = 0 or w - 9 = 0
w = -12 or w = 9
Since a width cannot be a negative number, we discard the solution w = -12.
width = w = 9
length = w + 3 = 9 + 3 = 12
Answer: The length is 12 cm, and the width is 9 cm.

A two digit number is such that, the sum of its digit is 13.When the digits are interchange, the original number is increased by 9. Find the original number.
Answer:
Concept: Mathematical Representation
You have a two digit # __ The sum of the two digit # = 13The original # increased by 9 Hence we must find values that sum to 13. *Note they must be independently standing.8+5, 9+6, 7+6 , 6+7 , and etcThe value must also increase by 9 So logically it would be any result that when switched that value would be 76-67= 9.So the value must be 67Hello' I'm trying again because I really need help.

Answer:
Factored Form: f(x) = (x-7)(x-4)
Roots: x=7, x=4
Step-by-step explanation:
What we can do here is break the given expression into groups;
x^2-11x+28 ---> break the expression into groups
(x^2-4x) +(-7x+ 28) ---> factor out x from x^2-4x
x(x-4) + (-7x +28) ---> factor - 7 from -7x +28
x(x-4) -7(x-4) ---> combine
(x-7)(x-4)
so if f(x) = (x-7)(x-4) then the roots would be x=7 and x=4

Answer:
= 5² = 25
= 36 ÷ 6 = 6
= 6 × 3 = 18
= 18 + 25 = 43
Step-by-step explanation:
The order of operations is PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction From Left to Right.
First is Exponents.
5² = 5×5 = 25
From left to right, division comes first.
36 ÷ 6 = 6
Then multiplication.
6 × 3 = 18
Lastly, addition.
18 + 25 = 43

Sharon makes bracelets and necklaces to sell at the school fair. She makes a total of 40 bracelets and necklaces. She makes 3 times as many bracelets as necklaces. Which system of equations can be used to determine how many bracelets, x, and how many necklaces, y, she m
Answer:
So, the system of equations are
x+y=40
x= 3 y
Step-by-step explanation:
Let's make system of equations for the given information.
Let x number of bracelets and y number of necklaces made.
So, for the information
She makes a total of 40 bracelets and necklaces, we can set up equation as
x+y=40
Now, for she makes 3 times as many bracelets as necklaces, we can set up equation as
x=3 y
