Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(2, -6), B(5, -6), C(5, -2) and D(2, -2). What is the perimeter of rectangle ABCD?

Answers

Answer 1

Answer:

14 units.

Step-by-step explanation:

Graph all the points on a coordinate grid. Two sides are 4 units each and the other two sides are 3 unites each.

P = 2(l + w)

P = 2(3 + 4)

P = 6 + 8 ← (The distributive property) OR 2(7) ← (Normal way to solve)

P = 14 units and 14 units.

You could also do addition.

P = 3 + 3 + 4 + 4

P = 6 + 8

P = 14 units

Identify the outlier in the data set and then find the mean and median with and without the outlier.

4, 14, 5, 2, 16, 138, 11

If necessary, round your answers to the nearest tenth.

outlier = 4

mean with outlier = 27.1

median with outlier = 11

mean without outlier = 41.6

median without outlier = 12.5

outlier = 4

mean with outlier = 11

median with outlier = 27.1

mean without outlier = 8

median without outlier = 8.7

outlier = 138

mean with outlier = 27.1

median with outlier = 11

mean without outlier = 8.7

median without outlier = 8

outlier = 138

mean with outlier = 8.7

median with outlier = 8

mean without outlier = 27.1

median without outlier = 11

Answers

Answer:

C. outlier = 138

mean with outlier = 27.1

median with outlier = 11

mean without outlier = 8.7

median without outlier = 8

Step-by-step explanation:

Hey there!

Well if the outlier is 138 then we can cross out choices A and B.

So let's find the mean with and without the outlier.

With - 27.1

Without - 8.7

Median)

With - 11

Without - 8

By using this information we can conclude that the answer is C.

I need help finding which one is the dependent variable and the independent variable.
Why do grocery stores hire most younger people than older people?

Answers

Are these separate questions? The dependent variable relies or depends on the independent. For example, if the cost of something was 2$ per item then the defendant variable would be the cost because if you have 1,2, or 3 items the cost will change depending on that

Answer:

Younger ppl- Independent variable

Older ppl - Dependent variable

Step-by-step explanation:

Older ppl r old and need more attention and they r usually slow workers......Whereas ypung ppl r active and energetic and can do work a lot faster the old ppl

When a figure appears to have depth as you look at it, it is called _____________.

Answers

Answer:

Step-by-step explanation:

Three-dimensional, or perspective view

The figure appears to have depth as you look at it, it is called Perception of Depth.

What is depth perception?

Depth perception is the way in which some animals, such as humans, can tell if a object is close or far away from them.

Depth perception is the ability that humans have to perceive depth. With depth perception animals are able to see something in three dimensions. The configuration of the eyes allows animals to see depth.

Having two eyes that is having binocular vision gives animals an accurate sense of depth.

Animals have evolved in such a way that gives us depth perception. In order for animals to survive in a three dimensional world depth perception is vital.

Step-by-step explanation:

3x2+x2=4x2

-x+5x=+4x

2-6=-4

Combine them for 4x2+4x-4

The correct expression will be 4x²+4x-4

What is expression?

Expressions in maths are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given are two expression:- P = 3x²-x+2 and Q = x²+5x-6

On adding the given expressions, we get,

P+Q = 3x²-x+2+x²+5x-6

= 3x²+x²-x+5x+2-6

= 4x²+4x-4

Hence, P+Q = 4x²+4x-4

50 points plus brainliest if you get the answer right! Compare the results with the theoretical probability of rolling a sum of 7. How does this comparison change as the number of trials increase? Use four of your vocabulary words in your explanation.

Answers

The chance of rolling 7 is infinite, the difference of the rolls would not decrease nor increase

The words I’d use to describe: Infinite, Impossible, plausible and implausible (at the same time)

When rolling two six-sided dice, the theoretical probability of getting a sum of 7 is 6/36 = 1/6 since there are 6 ways to roll a 7 (see the list of sums below) out of 6*6 = 36 outcomes total.

1+6 = 72+5 = 73+4 = 74+3 = 75+2 = 76+1 = 7

The experimental probability is just whatever results you record when you roll the two dice yourself. This will vary person to person. At first, the experimental probability is likely not going to be close to what it theoretically should be. However, as the number of rolls increases, the experimental probability should slowly approach the theoretical value.

The circle below has center C. Suppose angle EDF = 84º and DF is tangent to the circle at D.
Find the following. Type your numerical answers (without units) in each blank.

Answers

Answer: [tex]m\overbrace{ED}[/tex]= 168° and ∠ECD = 168°

Step-by-step explanation:

In the given , we have a circle centered at C , ED is a chord and DF is a tangent touching circle at D, ∠EDF = 84°.

Also, CE = CD = radius

⇒ ∠CED = ∠CDE ---(i) [angles opposite to equal sides of triangle are equal]

Since radius makes a right angle with tangent.

So, ∠CDF = 90°

⇒ ∠CDE =∠CDF - ∠EDF

⇒ ∠CDE= 90° - 84°

⇒ ∠CDE = 6°

From (i) ∠CED =∠CDE = 6°

In ΔCDE

⇒∠CED + ∠CDE + ∠ECD = 180°

⇒ 6°+6°+ ∠ECD = 180°

⇒ 12°+ ∠ECD = 180°

⇒∠ECD = 180° - 12°

⇒∠ECD = 168°

Since , Angle measure of the central angle is equal to the measure of the intercepted arc.

Therefore m∠ECD = [tex]m\overbrace{ED}[/tex]

⇒[tex]m\overbrace{ED}[/tex]= 168°

Hence, [tex]m\overbrace{ED}[/tex]= 168° and ∠ECD = 168°
