option C.
The statement that best describes a square is: A special rectangle that has four sides of equal length. This statement aligns with the definition of a square within the field of geometry, where a square is understood as a type of rectangle with all sides being the same length. Therefore, the correct answer is C. A special rectangle that has four sides of equal length.
A square indeed has four right angles, similar to a rectangle. By extension, it has congruent opposite sides and equal angles, but the defining feature that differentiates a square from other rectangles is the fact that all four sides are of equal length. The concept of rectangles forming squares can be seen in the given reference, implying that equal rectangles can be arranged to form a square - a concept important in understanding how a square is a special case of a rectangle.

Answer: [tex]y=\frac{1}{30}x+1[/tex]
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
[tex]y=mx+b[/tex]
Where "m" is the slope and "b" is the y-intercept.
You need to find slope of the line with the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Pick to points of the given line. You can choose the point (60,3) and the point (30,2).
Then, substituting into the formula:
[tex]m=\frac{2-3}{30-60}=\frac{1}{30}[/tex]
You can observe in the graph that the line intercepts the y-axis at the point (0,1), therefore "b" is:
[tex]b=1[/tex]
Substituting the slope and the y-intercept found into [tex]y=mx+b[/tex], you get the equation of this line:
[tex]y=\frac{1}{30}x+1[/tex]
Where "y" represents the Height (1,000 ft) and "x" represents the Time in seconds.

Step-by-step explanation:
Answer:
b=12 , a=6[tex]6 \sqrt{3}[/tex] , c=6[tex]\sqrt{2}[/tex]
Step-by-step explanation:
based on the graph you are showing, you can use "SOH CAH TOA"
for right triangles, then you use "CAH" for get b:
[tex]Cos(60)=\frac{6}{b}\\b*Cos(60)=6\\b*\frac{1}{2}=6\\ b=6*2\\b=12\\\\[/tex]
you do the same for a, but in this case you use sin, not cos:
[tex]sin(60)=\frac{a}{b} \\b*sin(60)=a\\\\12*\sqrt{3}/2=a\\ 6\sqrt{3}=a\\[/tex]
and with your b value, you can get c, but now you use Cos with the 45 angle:
[tex]b*cos(45)=c\\12*\sqrt{2}/2=c\\ 6\sqrt{2}=c[/tex]
remember SOH CAH TOA means, Sin(x)=opposite/Hypotenuse, Cos(x)=adjacent/hypotenuse, and tan(x)=Opposite/adjacent.

The function with a range of y < 3 among the given options is y=-(2)x +3, because it decreases by 2 for each increase in x, starting from y=3.
Explanation:The function which has a range of y < 3 is y=-(2)x +3. This is an example of a linear function where the slope is negative and the y-intercept is 3. This means that the y-values (the range) will always be less than 3. This is because the value of y will decrease by 2 for every increase in x, starting from y=3. For the other functions, the range of y-values is not consistently less than 3.

Sanjay solved the equation below. Which property did he use to determine that 7x+42=42 is equivalent to
7(x+6)=42
7x+42=42
7x=0
x=0
Step-by-step explanation:
7(x + 6) = 42
distributive property: a(b + c) = ab + ac
(7)(x) + (7)(6) = 42
7x + 42 = 42
subtraction property of equality (subtract 42 from both sides)
7x + 42 - 42 = 42 - 42
7x = 0
division property of equality (divide both sides by 7)
7x : 7 = 0 : 7
x = 0
Answer:
1. Distributive property: a(b + c) = a.b + a.c
2. Property of subtraction of equality
3. Property of division of equality
Step-by-step explanation:
The given equation is 7x + 42 = 42
7(x+6)=42 [Distributive property: a(b + c) = a.b + a.c]
7x+42=42 [Property of subtraction of equality]
Subtract 42 from both sides.
7x + 42 - 42 = 42 - 42
7x=0
Property of division of equality
Divide both sides by 7.

A movie rental kiosk has the following options to select from.
Genre: action, romance, comedy, horror, drama
Duration: less than 90 minutes, 90 minutes120 minutes, more than 120 minutes
If employees restock the kiosk by randomly adding movies into it, what is the probability that the next movie added is an action movie that is longer than 120 minutes?
Answer:
1/20
Step-by-step explanation:
To calculate how many potential combinations of genre and duration, we multiply the number of options in each category.
5 genres * 4 durations = 20 combinations
So for each film placed, there is a 1 in 20 chance that it will be a specific combination.
The probability that the next movie added is an action movie that is longer than 120 minutes is 1/20.
To calculate the probability that the next movie added is an action movie that is longer than 120 minutes, we need to make some assumptions, as the exact numbers of each category are not provided.
If we assume that movies are equally distributed among the different genres and durations, and there are 5 genres and 3 durations, we can conduct a probability calculation.
To calculate the probability that the next movie is an action movie longer than 120 minutes:
Calculate the probability of choosing an action movie, with 5 genres,
the probability is 1/5.
Calculate the probability of the movie being longer than 120 minutes, with 4 durations,
the probability is 1/4.
Multiply these two probabilities to get the combined probability
1/5 × 1/4 = 1/20 or 5%

For this case we have that by definition, the distance between two points is given by:
[tex]d = \sqrt {(y2-y1) ^ 2 + (x2-x1) ^ 2}[/tex]
We find the distance AB:
[tex]A: (3,4)\\B: (- 5, -2)[/tex]
[tex]AB = \sqrt {(x2-x1) ^ 2 + (y2-y1) ^ 2}\\AB = \sqrt {(- 5-3) ^ 2 + (- 2-4) ^ 2}\\AB = \sqrt {(- 8) ^ 2 + (- 6) ^ 2}\\AB = \sqrt {64 + 36}\\AB = \sqrt {100}\\AB = 10[/tex]
We have the BC distance:
[tex]B: (- 5, -2)\\C: (5, -2)[/tex]
[tex]BC = \sqrt {(5 - (- 5)) ^ 2 + (- 2 - (- 2)) ^ 2}\\BC = \sqrt {(5 + 5) ^ 2 + (- 2 + 2) ^ 2}\\BC = \sqrt {(10) ^ 2 + (0) ^ 2}\\BC = \sqrt {100}\\BC = 10[/tex]
We find the CA distance:

julie has $80 in her savings account and plans to save $x each month for 8 months.The expression $8x+$80 represents the total amount in the account after 8 months.Factor this expression
Answer:
[tex]8(x+10)[/tex]
Step-by-step explanation:
we have the expression
[tex](8x+80)[/tex]
we know that
[tex](8x+80)=(8x+8(10))[/tex]
Factor the number 8
[tex](8x+8(10))=8(x+10)[/tex]
therefore
The expression factored is [tex]8(x+10)[/tex]
The factorization of the given expression is given as:
[tex]8(x+10)[/tex]
Step-by-step explanation:To factor a algebraic equation means to represent it as the multiplication of the simple expressions.
( i.e. if the expression has a common multiple in each of the terms then we take it out and represent the rest of the expression in brackets.
Also, we can express a algebraic equation by the multiplication of the factors of the expression )
We are given a expression as:
[tex]8x+80[/tex] which represents the total amount in the account after 8 months.
and x represents the amount saved each month.
Since both the terms i.e. 8x and 80 have a common multiple as: 8
Hence, we take it out of the expression and write the resulting expression as follows:
[tex]8x+80=8(x+10)[/tex]

The subtraction gives us:
0 , -1 , -2, -3, -4, -5, 1, 0, -1, -2, -3, -4, 2, 1, 0, -1, -2, -3, 3, 2, 1, 0, -1, -2, 4, 3, 2, 1, 0, -2, 5, 4, 3, 2, 1, 0
So the distribution will be as follows:
X 5 4 3 2 1 0 -1 -2 -3 -4 -5
P(X) 1/36 2/36 3/36 4/36 5/36 6/36 5/36 4/36 3/36 2/36 1/36

Which mathematical statements are true?
1) If 3 is an odd number, then 3 times 3 is an even number.
2) If 6 is less than 7, then 4 is greater than 7.
3) Six is divisible by 3, and 10 is a multiple of 2.
4) The average of the data is greater than the largest value in the data, or it’s less than the largest value in the data.
5) The slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value.
6) If an equilateral triangle has equal angles, then all its angles will measure 45°.
Answer:
1) If 3 is an odd number, then 3 times 3 is an even number.
False because multiplying odd number by an odd number also gives an odd number.
2) If 6 is less than 7, then 4 is greater than 7.
False because 4 is smaller than 6. As 6 is smaller than 7 then 4 must also be smaller.
3) Six is divisible by 3, and 10 is a multiple of 2.
True. 6/3 = 2 and 2 x 5 = 10. Both the conditions are true so it is also true.
4) The average of the data is greater than the largest value in the data, or it’s less than the largest value in the data.
True.
We have two conditions in this statement and an 'or' between them. One of the conditions is true that is "average is less than the largest value in the data". So the statement as a whole is true.
5) The slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value.
True.
6) If an equilateral triangle has equal angles, then all its angles will measure 45°.
False.
A triangle has 3 angles whose sum = 180 degrees.
For equilateral triangle each angle will measure 180/3= 60 degrees.
Answer: 2 following statements are true
The first true statement:
Six is divisible by 3, and 10 is a multiple of 2.
We know this because 6 is divisible by 3, and again proven by when we divide 10 by 5 we get 2, so 10 is a multiple of 2.
The second true statement:
The slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value.

ones are in the control group.
O
A. placebo-effect
O
B. control
O
C. double-blind
O
D. biased
Answer:
C. double-blindStep-by-step explanation:
A double-blind study is a study where neither participants nor experimenters know which subjects are receiving the treatment.
This method is really useful to minimize possible biased conclusions about the experiment.
Therefore, the right answer is C, the situation described refers to a double-blind study.
A double-blind study is an experimental design in which both the subjects and experimenters are unaware of the treatment or control group assignments, thereby reducing bias and increasing the reliability of the study's findings.Therefore, the correct answer is option C.
An experiment where neither the subjects nor the experimenters know which subjects are in the treatment or control group is best described as a double-blind study.
This type of research design is crucial to prevent biases from affecting the outcome of clinical trials or other medical studies. In a double-blind study, both the participants and researchers are 'blind' to the assignments, thereby reducing the risk of placebo effects or experimenter bias influencing the results.
Experiments in the field of medicine often use this design to test the efficacy of new drugs, treatments, or interventions in the most unbiased way possible.
A control group that receives a placebo is essential in these experiments to compare the actual efficacy of the experimental treatment against no treatment or a standard treatment.

f(-2) = 3* abs(-4) + 1
f(-2) = 3 * 4 + 1
f(-2) = 13

a triangular pyramid has a triangular base with a height of 1.5 inches and base length of 4 inches, and height of 9 inches. What is the volume ?
Step-by-step explanation:
Volume of a pyramid is:
V = ⅓ AH
where A is the area of the base and H is the height of the pyramid.
The base is a triangle. Area of a triangle is:
A = ½ bh
where b is the base length and h is the height.
A = ½ (4)(1.5)
A = 3
V = ⅓ (3)(9)
V = 9
The volume is 9 in³.
The volume of the triangular pyramid with a triangular base is 9 cubic inches.
What is the volume of a triangular pyramid?The volume of the triangular pyramid with a height h and base area B is
Volume = 1/3 × B × h cubic units
What is the area of a triangle?The area of a triangle is 1/2 × b × h sq. units
where b - base and h - height the triangle.
Calculating the volume:It is given that a triangular pyramid has a triangular base with
base length b = 4 inches
height of the triangle h = 1.5 inches and
height of the pyramid = 9 inches
So, the volume of the pyramid = 1/3 × B × h
Where base area B = 1/2 × b × h
⇒ B = 1/2 × 4 × 1.5
= 3.0 sq. inches
