The correct answer is C. Coplanar, line.
The undefined terms are needed to define parallel lines are coplanar and line.
<h3>What are parallel lines?</h3>
Two lines in a single plane that are equally spaced apart and never cross each other are said to be parallel lines in geometry. All horizontal and vertical shapes are possible.
Examples of parallel lines can be found everywhere, including zebra crossings, rows of notebooks, and the nearby railroad tracks.
Some characteristics of parallel lines are-
- They are usually parallel straight lines that are spaced equally apart.
- These lines are coplanar.
- No regardless how far you extend these in any direction, they never come together.
- A transversal line will create four angles at each of its two sites of intersection with two parallel lines if it does so.

Step-by-step explanation:
Hello!
To test if boys are better in math classes than girls two random samples were taken:
Sample 1
X₁: score of a boy in calculus
n₁= 15
X[bar]₁= 82.3%
S₁= 5.6%
Sample 2
X₂: Score in the calculus of a girl
n₂= 12
X[bar]₂= 81.2%
S₂= 6.7%
To estimate per CI the difference between the mean percentage that boys obtained in calculus and the mean percentage that girls obtained in calculus, you need that both variables of interest come from normal populations.
To be able to use a pooled variance t-test you have to also assume that the population variances, although unknown, are equal.
Then you can calculate the interval as:
[(X[bar]_1-X[bar_2) ±
*
]


[(82.3-81.2) ± 1.708* (6.11*
]
[-2.94; 5.14]
Using a 90% confidence level you'd expect the interval [-2.94; 5.14] to contain the true value of the difference between the average percentage obtained in calculus by boys and the average percentage obtained in calculus by girls.
I hope this helps!
Answer:
13+2x=67 soooooo x = 27 so the video game is $27 and thats the equation
Step-by-step explanation:
Answer:
a) r→q
b) r→p
c) r→p
d) r→ p∧q
e) r→ p∨q
Step-by-step explanation:
Using logical connectives, as shown in the picture below, we can write all of the statements of the question.
p:"You get an A on the final exam"
q:"You do every exercise in this book"
r:"You get an A in this class"
a) r→q
b) r→p
c) r→p
d) r→ p∧q
e) r→ p∨q
Answer: You divide the top row by itself and you multiply the top by 2 each time.
Step-by-step explanation: Multiply 72 by 2 each time on top and the bottom row just simply add 1.
Sorry if it is wrong but i hope it helps!
