What angle relationship describes ∠VQR and ∠QRW?

segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively

A) Alternate interior angles
B) Alternate exterior angles
C) Corresponding angles
D) Vertical angles

Answers

Answer:

its A on the quiz (alternate interior)

Step-by-step explanation:

The required angle relationship describes ∠VQR and ∠QRW is both angles are alternate interior angles. Option A is correct.

Given that,
Segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively. What angle relationship describes ∠VQR and ∠QRW is to be determined.

What are parallel lines?

Parallel lines are defined as the pair of line that has the distance between the point corresponding to the line are equal and this line met at infinity.

What is angle?

The angle can be defined as the one line inclined over other line.

Since it is to describe that what is the relationship between  ∠VQR and ∠QRW.
Here, both angles are interior and alternate in the figure so both angles have a relationship to the alternate interior angle by property of parallel lines.


Thus, the required angle relationship describes ∠VQR and ∠QRW is both angles are alternate interior angles. Option A is correct.

what is the expression for the probability when the disease D is present but the test says its not? P = Event that test is positive, D = Event disease is present

Answers

Answer:

[tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

Step-by-step explanation:

Given

P = Test is positive

D = Disease is present

Required

Write an expression when disease is present but test says that the disease is not present

The above statement can be split to two

Disease is Present          &        Test is not positive

The first statement:

Disease is Present  means D

The second statement

Test is not positive means not P

Mathematically;

not P means P' or [tex]P^c[/tex]

So, the required expression is: [tex]P(D\ and\ P^c)[/tex] or [tex]P(D\ and\ P')[/tex]

What is parametric equation?

Parametric equation actually refers to the equation that is used to set a group of quantities as functions. These functions are functions of one or more variables that are independent. These independent variables are known as parameters.

Such parametric equations can be used to express coordinates of a point.

The cost will never be the same. 5 months 5 months 7 months 7 months 10 months \

Answers

Answer:

After 5 months

Step-by-step explanation:

Step one:

given data

LA Fitness charges a registration fee of $75 plus $35.75 per month for members

let the number of months be x

and the total charges be y

total is

y= 75+35.75x----------1

Gold's Gym charges a registration fee of $164 plus $17.95 for members

let the number of months be x

and the total charges be y

total is

y= 164+17.95x----------2

Step two:

equate 1 and 2

75+35.75x= 164+17.95x

solve for x

35.75x-17.95x=164-75

17.8x=89

divide both sides by 17.8

x=89/17.8

x=5 months

Read this excerpt from Drummer Man. It turned out to be a good thing that I signed on again. It wasnt long into my second year when our regiment fought at the Siege of Corinth. In the heat of the fight we made a desperate charge across a ravine and Captain Williamson was wounded. So the call came in for a quick retreat, but unfortunately the captain was left there between the lines. Somebody had to rescue him, and it was one of two times during the war that I was happy for being small. I took off in a stooping run, unseen by the enemy, and somehow found the strength to drag Williamson back to the stretcher bearers and out of harms way. The second time I was glad for my slight height occurred when I was caught behind the enemy lines. All I can guess is that those rebels who surrounded me mistook me for a child.
