In an anonymous survey 34 students reported the hours they studied for a statistics final exam. The histogram below shows the re

sults of the survey. histogram Which statement below is the most accurate description of the center of the distribution?
A. The median should be used to describe the center, because the values on the horizontal axis can be spit exactly in the middle.
B. The mean should be used to describe the center because it may produce a decimal value, which is more accurate than the median.
C. The mean should be used to describe the center because the data is roughly symmetric.
D. The median should be used to describe the center because, since the data is skewed, the middle outcome may more accurately describe a typical value in the distribution.

Find the solution of the system of equations.<br> -9x - 5y = -18<br> 4x + 5y = 33
Rus_ich [418]

Answer:

x=-3, y=9. (-3, 9).

Step-by-step explanation:

-9x-5y=-18

4x+5y=33

---------------

-5x=15

x=15/-5

x=-3

4(-3)+5y=33

-12+5y=33

5y=33-(-12)

5y=33+12

5y=45

y=45/5

y=9

In circle A, ∠BAE ≅ ∠DAE. Circle A is shown. Line segments A B, A E, and A D are radii. Lines are drawn from point B to point E
xeze [42]

Answer:

The missing figure is attached down

The length of BE is 27 units ⇒ 3rd answer

Step-by-step explanation:

In circle A:

  • ∠BAE ≅ ∠DAE
  • Line segments A B, A E, and A D are radii
  • Lines are drawn from point B to point E and from point E to point D to form secants B E and E D
  • The length of B E is 3 x minus 24 and the length of E D is x + 10

We need to find the length of BE

∵ AB and AD are radii in circle A

∴ AB ≅ AD

In Δs EAB and EAD

∵ ∠BAE ≅ ∠DAE ⇒ given

∵ AB = AD ⇒ proved

∵ EA = EA ⇒ common side in the two triangles

- Two triangles have two corresponding sides equal and the

   including angles between them are equal, then the two

   triangles are congruent by SAS postulate of congruence

∴ Δ EAB ≅ Δ EAD ⇒ SAS postulate of congruence

By using the result of congruence

∴ EB ≅ ED

∵ EB = 3 x - 24

∵ ED = x + 10

- Equate the two expressions to find x

∴ 3 x - 24 = x + 10

- Add 24 to both sides

∴ 3 x = x + 34

- Subtract x from both sides

∴ 2 x = 34

- Divide both sides by 2

∴ x = 17

Substitute the value of x in the expression of the length of BE to find its length

∵ BE = 3 x - 24

∵ x = 17

∴ BE = 3(17) - 24

∴ BE = 51 - 24

∴ BE = 27

The length of BE is 27 units

Okay so imugwy and wat is 100*3/6
jonny [76]

Answer:

what is your questions mate I mm didn't understand ¯\_(ツ)_/¯

Step-by-step explanation:

,When a percent amount is multiplied to another number, the operation produces a value that equals the given percent of the original number. ... Multiplying a number by 100 percent is a just variation of the multiplicative identity and will result in the value being unchanged.
