HELP!

The Mean Of Data Set A Is 42. The Mean Of Data Set B Is 47. The Mean Absolute Deviation (MAD) Of Both

Answers

Answer 1

Answer:

The difference of the means is 2 times the MAD

Step-by-step explanation:

Mean of data set A = 42

Mean of data set B = 47

MAD of both data sets = 2.5

Difference of their means = 47 - 42 = 5

Thus, the difference of their means = 2 × the MAD

= 2 × 2.5 = 5

Therefore:

The difference of the means is 2 times the MAD

At last week's track meet, Stacy ran 9/12 of a km, Jules ran 4/5 of a km, and Raul ran 3/4 of a mile. Which two students ran the same distance?

Answers

Answer:  No two students ran same distance

Step-by-step explanation:

Given

Stacy ran [tex]\frac{9}{12}[/tex] of a km i.e.

[tex]\Rightarrow 1\times \dfrac{9}{12}=\dfrac{3}{4}=0.75\ km[/tex]

Jules ran [tex]\frac{4}{5}[/tex] of a km i.e.

[tex]\Rightarrow 1\times \dfrac{4}{5}=0.8\ km[/tex]

Raul ran [tex]\frac{3}{4}[/tex] of mile i.e.

[tex]\Rightarrow 1\times \dfrac{3}{4}=0.75\ miles\\\\\text{1 mile=1.6 km}\\\\\Rightarrow 0.75\ miles=1.2\ km[/tex]

So, no two students ran the same distance.

Armed gunmen shoot a victim who is 5.9 ft tall, from the roof of a building that is 146 ft away. If the roof of the building was 385 ft high, at what angle to the horizon would the bullet have been fired?

Answers

The bullet has been fired at an angle of 69.5° to the horizon. This is a problem based on the application of trigonometry.

Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles.

Given that

Distance between the building and the man = 146 ft.

Height of the man = 5.9 ft.

Height of the building = 385 ft.

So,

Total height = Height of the man + Height of the building

                    = 5.9 ft. + 385 ft.

                    = 390.9 ft.

Let the angle to the horizon would the bullet have been fired be x°.

[tex]tanx^o = \frac{390.9}{146}\\tanx^o = 2.677\\x = tan^{-1}(2.677)\\x = 69.5[/tex]

Thus, the bullet has been at an angle of 69.5°.

4.13% of______
5.15 is 12.5% of _____​

Answers

Answer:

1-    10% of -80 is -8.  

2-    28 is 4% of 700.

3-   25% of a number is equal to 1/4 or 0.25 of it.

4-    13% of a number is equal to 0.13 of it.

5-    15 is 12.5% of 120.

Step-by-step explanation:

1. 10% of ________- 8

2.28 is 4% of _________

3.25% of ________

4.13% of______

5.15 is 12.5% of _____

To determine the missing numbers in the statements, the following calculations must be performed:

1-

10 = -8

100 = X

100 x -8 / 10 = X

-800 / 10 = X

-80 = X

Therefore, 10% of -80 is -8.

two-

4 = 28

100 = X

100 x 28/4 = X

2800/4 = X

700 = X

Therefore, 28 is 4% of 700.

 

3-

25% of a number is equal to 1/4 or 0.25 of it.

4-

13% of a number is equal to 0.13 of it.

5-

12.5 = 15

100 = X

100 x 15 / 12.5 = X

1500 / 12.5 = X

120 = X

Therefore, 15 is 12.5% of 120.

∠ A and ∠ B are alternate exterior angles and are congruent, that s

8x + 6 = 4x + 38 ( subtract 4x from both sides )

4x + 6 = 38 ( subtract 6 from both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Then

∠ B = 4x + 38 = 4(8) + 38 = 32 + 38 = 70°

Her new job in New York City was great, but there were lots of things she had to get used to. The first thing she had to deal with was noise. The sound of traffic never ceased. Sirens wailed suddenly at all hours. Garbage trucks backed into the alley beneath her apartment and made a terrible noise. They always seemed to arrive at 5:00 in the morning. The second thing she had to deal with was getting to work. The crush of the crowded sidewalks made her feel as if she was being swept by a tide of people. Everyone seemed to know where they were going and they walked fast. Maria felt that she had to walk fast too, just to keep from getting lost in the crowd. Soon after beginning her new job in downtown Manhattan, Maria had to deal with a third thing. Walking on concrete and standing on the subway were hard on her feet. Soon, she learned to imitate her fellow workers. She came to work in sneakers, carrying her dress shoes in her tote bag.Once youve read this paragraph, look over the following ideas to see which one best describes its topic.a.
