A = {a, b, c, d}

Answer:

No, Johnny is not correct

A U B = {a,b,c,d,e,f,g,h}

Step-by-step explanation:

Johnny's answer does not have c and d, elements that are in A and B, so A U B must have all elements that belong to A or B.

The (U) represents the sum of elements between two sets. So If a set has three elements {@,#,$} and another set has 5 elements {%,^,&}, (U) equals the sum of these sets: {@,#,$,%,^,&}.

The same is true for the sets A and B.

A = {a, b, c, d}

B = {c, d, e, f, g, h}

A U B = {a,b,c,d,e,f,g,h}

Note: c, d are repeated, in A and B. It is not necessary to write them twice in the final answer.

Answer:

1. In the first section (“The CSI effect defined”), do the authors ever give you their opinion on the CSI effect? How do they support their definition and their expansion on the definition? How many different sources do they cite in this section?

The authors do not give their opinion on the CSI effect. They support their definitions through multiple peer reviewed sources on the topic of “CSI Effects”. There were in total five different sources cited in the first section.

2. From pages 86-88, the authors discuss lawyers, police officers, judges, and community members. In this section, do the authors ever give you their opinion on any of the issues discussed?

From pages 86-88, the authors don’t give their opinions on any of these topics. They only present what other scholars have studied and put this information into their own literature review paper.

3. Examine the section entitled “Verdicts” (pp. 90-92). How do the results from the study by Shelton et al. differ from the results of the study by Kim, Barak, and Shelton? How do the results of the study by Baskin and Sommers differ from the results of other studies?

Shelton et al’s study on verdicts focused on those who watch or don’t watch CSI shows and that neither plays a role when jurors decide on a verdict on a suspect. Kim, Barak, and Shelton differs from the first study in that exposure from watching these shows does have an indirect affect to jurors concerning circumstantial evidence. If the case has circumstantial evidence, the jurors are more influenced in giving a verdict. Baskin and Sommers results differ from the rest in that they used a telephone survey to see how likely one would convict a suspect using no scientific evidence. The others focused on watching shows and using circumstantial evidence as basis for verdict, whereas Baskins and Summers article focuses more on attitudes than the behaviors when determining verdict decisions.

4. As a result of having read this article, please write a few sentences about what you might have learned about a) synthesizing sources or b) the CSI effect.

While reading this article and finishing my own literal review, I have learned that the authors synthesize their research according to how they understand the topic. Also, I noticed scholars that do research on a specific topic find similar and different forms of information, but write it according to how the instructor or audience wants it done. The CSI effect article is just another example of this.

Ray is constructing a flowerbed for the zoo and wants to

faust18 [17]

Answer:

Option (3)

Step-by-step explanation:

Since, flowerbed is in the shape of a right triangle,

By applying Pythagoras theorem in the given right triangle,

(Hypotenuse)² = (leg 1)² + (leg 2)²

(Hypotenuse)² = (12)² + (12)²

(Hypotenuse)² = 144 + 144

Hypotenuse = √288

Hypotenuse = 16.97

≈ 17 ft

Perimeter of the triangle = Sum of the measures of three sides of the triangle

= 12 + 12 + 17

= 41 ft

Therefore, Option (3) will be the correct option.

(I need the answer right now please) ΔA'B'C' was constructed using ΔABC and line segment EH. 2 triangles are shown. Line E H is

irina1246 [14]

Answer:

The true statements are

1. BD = DB'

3. m∠EFA = 90°

4. The line of reflection, EH, is the perpendicular bisector of BB', AA', and

CC'

Step-by-step explanation:

* Lets explain how to solve the problem

- Reflection is flipping an object over the line of reflection.

- The object and its image have the same shape and size, but the

figures are in opposite directions from the line of reflection

- The objects appear as if they are mirror reflections, with right and left

reversed

- The line of reflection is a perpendicular bisector for all lines joining

points on the figure with their corresponding images

- Look to the attached figure for more understand

* Lets solve the problem

- ΔA'B'C' was constructed using ΔABC and line segment EH, where

EH is the reflection line

- D is the mid-point of BB'

- F is the mid-point of AA'

- G is the mid-point of CC'

* Lets find from the answer the true statements

1. BD = DB'

∵ D is the mid point of BB'

- Point D divides BB' into two equal parts

∴ BD = DB' ⇒ True

2. DF = FG

- It depends on the size of the sides and angles of the triangle

∵ We can't prove that

∴ DF = FG ⇒ Not true

3. m∠EFA = 90°

∵ The line of reflection ⊥ the lines joining the points with their

corresponding images

∴ EH ⊥ AA' and bisect it at F

∴ m∠EFA = 90° ⇒ True

4. The line of reflection, EH, is the perpendicular bisector of BB',

AA', and CC'

- Yes the line of reflection is perpendicular bisectors of them

∴ The line of reflection, EH, is the perpendicular bisector of BB',

AA', and CC' ⇒ True

5. ΔABC is not congruent to ΔA'B'C'

∵ In reflection the object and its image have the same shape and size

∴ Δ ABC is congruent to Δ A'B'C'

∴ ΔABC is not congruent to ΔA'B'C' ⇒ Not true
