Answer:

A.

Step-by-step explanation:

A polyhedron is a 3d figure that has flat polygonal faces.

Since this 3d shape has octagons on its faces and rectangles on its sides, it is considered a polyhedron.

Counting everything adds up to 10 faces, 16 vertices, and 24 edges.

Answer:

Step-by-step explanation:

the first sounds like J/9=5, which in an equaiton could be written as 5=j/9.

Then to solve for j you can multiply both sides by 9. This would create j=45. Hopefully this is helpful!

Answer:

[tex]\frac{j}{9}[/tex] = 5 is the equation, j = 45 is the answer.

Step-by-step explanation:

J divided by 9 is 5.

[tex]\frac{j}{9}[/tex] = 5.

Multiply by 9 to find the answer.

j = 5 * 9

j = 45.

No, the facility dose not have the exact pattern as the recent report at the 10% level.

To determine if the Facility have the same pattern,

By using Chi squared test for Goodness of fit state the hypothesis

[tex]$H_{0}[/tex] : μ = same pattern

[tex]$H_{a}[/tex] : μ ≠ same pattern

Expected frequency (E)  = proportion [tex]*[/tex] summation of frequency

summation of frequency = 1000

degree of freedom [tex]= 7 - 1 = 6[/tex]

Calculate the expected frequency (E) ,(O-E)²/E.  

Given that the observed frequency and expected proportion exists given

For Monday

expected frequency = proportion [tex]*[/tex] frequency = 0.1 [tex]*[/tex] 1000 = 100

(O-E)²/E.  = ( 120 - 100 )² / 100 = 4.0.

observed frequency (O), expected frequency (E)

For Tuesday

E = 0.1 [tex]*[/tex] 1000 = 100

(O-E)²/E  = ( 130 - 100 )² / 100 = 9.0

For Wednesday through Sunday

Then perform Chi-squared test

X² = Σ(O-E)²/E  = 63.642    

∝ = 0.1

df = 6

hence P-value = 0.000 ( = chi sq dist rt(test-stat,df)

since P-value < ∝ ; we will fail to reject Ha  hence we reject [tex]$H_{0}[/tex].

Answer:

21.11 ft

Step-by-step explanation:

This question would be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

13.4² + b² = 25²

179.56 + b² = 625

b² = 625 - 179.56

b = 445.44

find the square root of 445.44

b = 21.11 ft

Answer:

P(A or B) = 0.75

Step-by-step explanation:

Venn probabilities:

Supposing that we have two events A and B, the probability P(A or B) is given by:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

In this question, we have that:

[tex]P(A) = 0.62, P(B) = 0.25, P(A \cap B) = 0.12[/tex]

So

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.62 + 0.25 - 0.12 = 0.62 + 0.13 = 0.75[/tex]

Then

P(A or B) = 0.75

Answer:

a. tanB= 3/2

Step-by-step explanation:

tanA= p/b =:2/3

For angle A,

p= 2

b=3

For angle B,

p = 3

b=2

So, TanB = 3/2

Answer:

28 degrees

Step-by-step explanation:

The given figure is an octagon. The sum of interior angles in an octagon is 1080. Thus, one can form an equation, add up all of the angle measures, and set the equation equal to 1080. Then simplify and use inverse operations to find the value of the parameter (t).

(150) + (3t + 34) + (5t) + (5t) + (3t + 37) + (7t - 49) + (5t - 16) + (5t) = 1080

Simplify,

33t + 156 = 1080

Inverse operations,

33t + 156 = 1080

      -156       -156

33t = 924

/33     /33

t = 28

Answer:

z = 166°

Step-by-step explanation:

Given:

x = 89

y = 12

An angle with its vertex in a circle = ½(intercepted arcs)

Thus:

x = ½(y + z)

Substitute

89 = ½(12 + z)

Multiply both sides by 2

2(89) = 12 + z

178 = 12 + z

178 - 12 = z

z = 166°
