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:

28.27 or 28 rounded up.

Answer:

7.07 in²

Step-by-step explanation:

Diameter = 3 in ( shown in figure )

Radius = 1/2( diameter) = 1/2 (3) = 1.5 in

Area of a circle = πr²

Area = (3.14)(1.5)²

Area = (3.14)(2.25)

Area = 7.065 in

Area = 7.07 in² ( round off)

Answer:

28.5

Step-by-step explanation:

The sum of the interior angles in a triangle is equal to 180

102 + x + 6 + x + 15 = 180

123 + 2x = 180 subtract 123 from both sides

2x = 57 divide both sides by 2

x = 28.5

Answer:

x = 30 degrees

Step-by-step explanation:

a triangle's angles should all add up together to 180 degrees. Since a right angle is 90 degrees then you have your 60 degree angle that only leaves 30 degrees left.

Answer: A and C

Step-by-step explanation:

A is right because it’s right triangle since it has a right angle. C is also right, x=30 because we have 60 degrees and 90 degrees. 60 plus 90 is 150 and a triangle is equal to 180 degrees 180-150 is 30

Answer:

[tex]K \approx 51.2^\circ[/tex]

[tex]K \approx 128.8^\circ[/tex]

Step-by-step explanation:

Given

[tex]k = 480[/tex]

[tex]j = 420[/tex]

[tex]\angle J = 43^\circ[/tex]

Required

Find the measure of K

The value of K ranges from: [tex]0^\circ \le K \le 180^\circ[/tex]

To do this, we apply sine rule;

[tex]\frac{j}{\sin J} = \frac{k}{\sin K}[/tex]

So, we have:

[tex]\frac{420}{\sin 43} = \frac{480}{\sin K}[/tex]

Cross multiply

[tex]\sin K * 420 = \sin 43 * 480[/tex]

Make sin K the subject

[tex]\sin K= \frac{\sin 43 * 480}{420}[/tex]

[tex]\sin K= \frac{0.6820 * 480}{420}[/tex]

[tex]\sin K= 0.7794[/tex]

Take arc sin of both sides

[tex]K = sin^{-1}(0.7794)[/tex]

[tex]K \approx 51.2^\circ[/tex]

Recall that: [tex]0^\circ \le K \le 180^\circ[/tex]

The other possible value of K is:

[tex]K \approx 180 - 51.2[/tex]

[tex]K \approx 128.8^\circ[/tex]

Answer:

huh i dont get it

Step-by-step explanation:

Answer:

b = 9m is the answer.

Step-by-step explanation:

a = 12m

b = ?

c = 15m

According to the Pytagorean theorem,

a² + b² = c²

12² + b² = 15²

144 + b² = 225

b² = 225 - 144

b² = 81

b = 9

∴ The slide is 9m away from the monkey bars.

Answer:

La planta de la que ha salido el ascensor es: -1(planta del sótano)

Datos:

Subió 8 pisos

Piso final= 7

Explicación:

Para resolver el enunciado, se debe tener en cuenta que:

Piso final - Piso inicial= 8

Reemplazando y despejando:

7-Piso inicial= 8

Piso inicial= 7-8

Piso inicial= -1

Por lo tanto, ha salido de la planta del sótano

Verificando:

Piso inicial +8= piso final

-1+8= Piso final

7= piso final

Answer:

FV= $7,040.46

Step-by-step explanation:

Giving the following information:

Initial investment (PV)= $5,500

Number of periods (n)= 10 years

Interest rate (i)= 2.5%

To calculate the future value (FV), we need to use the following formula:

FV= PV*(1 + i)^n

FV= 5,500*(1.025^10)

FV= $7,040.46

What types of nouns should be used in effective process writing?

Step-by-step explanation:

Answer:

C) 3x and 7x

Step-by-step explanation:

Both terms in C have the same variable in which you can combine the terms to make 1. The other ones don't.

Answer:

c. 3x and 7x

Step-by-step explanation:

We have three pairs of two terms and are asked to determine which option has "like terms."

Like terms are two numbers with variables that are the same.

With this information, we can determine which is and which isn't like terms.

a. 2x^2 and 4y^2 are incorrect because the variables within the number do not match, 2x^2 and 4y^2.

b. xy and yz are incorrect because the variables also do not match, xy and yz.

c. is correct because the variables within the two numbers are the same. 3x and 7x.
