Which undefined terms are needed to define parallel lines quizlet?
HACTEHA [7]

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.

If 8 ounces of a sports drink contain 110 milligrams of sodium what is the total number of milligrams of sodium in 20 ounces of
Sati [7]
The milligrams of sodium in a 20 ounce sports drink is 275 milligrams.
Work:
I divided 110 by 8 which gave me 13.75
13.75 is the milligrams of sodium in each ounce.
I then divided it by 20 and got 275 the number of milligrams in a 20 ounce drink.

National statistics show that 23% of men smoke and 18.5% of women smoke. A random sample of 175 men indicated that 45 were smoke
NeTakaya

Answer:

98% C.I. = [-0.1270, 0.0994]

Step-by-step explanation:

Here

p1= proportion of men smokers

p1= 45/175= 0.2571

p2= proportion of women smokers

p2= 42/155= 0.2709

1)  Choose the significance level ∝= 0.02

2) The formula for confidence interval is

(p1^- p2^)- z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

and

(p1^- p2^) z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

<u>3)  The z value is 2.05</u>

<u>4) Calculations:</u>

(p1^- p2^)- z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

Putting the values

= 0.2571-0.2709)(-2.05) sqrt ( 0.2571(1-0.2571)/175+ 0.2709(1-0.2709)/155)

=-0.1270 ( using calculator)

And

(p1^- p2^)z ∝/2sqrt( p1^(1-p1^)/n1 + ( p2^(1-p2^)/n2))

Putting the values

= 0.2571-0.2709)(2.05) sqrt ( 0.2571(1-0.2571)/175+ 0.2709(1-0.2709)/155)

=0.0994  ( using calculator)

and Putting ± 2.05 in the confidence interval formula we get limits (-0.1270, 0.0994)
