Complete question :

According to the National Association of Realtors, it took an average of three weeks to sell a home in 2017. Suppose data for the sale of 39 randomly selected homes sold in Greene County, Ohio, in 2017 showed a sample mean of 3.6 weeks with a sample standard deviation of 2 weeks. Conduct a hypothesis test to determine whether the number of weeks until a house sold in Greene County differed from the national average in 2017. Useα = 0.05for the level of significance, and state your conclusion

Answer:

H0 : μ = 3

H1 : μ ≠ 3

Test statistic = 1.897

Pvalue = 0.0653

fail to reject the Null ; Hence, we conclude that their is no significant to accept the claim that number I weeks taken to sell a house differs.

Step-by-step explanation:

Given :

Sample size, n = 40

Sample mean, x = 3.6

Population mean, μ = 3

Standard deviation, s = 2

The hypothesis :

H0 : μ = 3

H1 : μ ≠ 3

The test statistic :

(xbar - μ) ÷ (s/√n)

(3.6 - 3) / (2/√40)

0.6 / 0.3162277

Test statistic = 1.897

Using T test, we can obtain the Pvalue from the Test statistic value obtained :

df = n - 1; 40 - 1 = 39

Pvalue(1.897, 39) = 0.0653

Decison region :

If Pvalue ≤ α ; Reject the null, if otherwise fail to reject the Null.

α = 0.05

Pvalue > α ; We fail to reject the Null ; Hence, we conclude that their is no significant to accept the claim that number I weeks taken to sell a house differs.

Answer:

11 cm

Step-by-step explanation:

r² = 9² + 6.3²

r² = 120.69

r = 10.9859000542

Rounded

r = 11 cm

Answer:

[tex]\rm 10.9 cm [/tex]

Step-by-step explanation:

Given that :-

And we need to find out the radius of the circle.

[tex]\text{ Theorem :-}[/tex]

Using Pythagoras Theorem :-

[tex]\implies \rm OA^2= AB^2+OB^2\\\\\rm\implies OA^2= (6.3 cm)^3+(9cm)^2\\\\\rm\implies OA^2=

120.69 \\\\\implies\boxed{\rm OA = 10.9 cm }[/tex]

Hence the radius is 10.9 cm

Answer:

1/4

Step-by-step explanation:

For the first circle 2 x 2in = 4 to find diameter

4 x 3.14 = 12.56

6in x 2 = 12

12 x 3.14 = 37.68

simplify

12.56/37.68

6.28/18.84

3.14/9.42

So the answer is 1/4 since 3.14 x 2 = 6.28

Also since the radius is 2 times longer

Answer:

D

Step-by-step explanation:

Circumference = 2 * pi * r

Circle A / Circle B = 2 * pi * 8 / 2 * pi * 2

You need to take note of the right side. The 2s cancel and so does pi

Circle A/ Circle B = 8/2

Circle A / Circle B = 4/1 = 4

Which is D

Answer:

c

Step-by-step explanation:

The y-values of the graph increases as the value of x increases, which

indicates that a characteristic of the base of the logarithm function.

Correct response:

The given points on the graph are;

The point where the graph starts = Quadrant 4

Direction of the graph = From quadrant 4 to quadrant 1

Points on the graph are;

(0.5, -0.4), (1, 0), and (6, 1)

The given options are;

[tex]y = \mathrm{log_{\frac{1}{6} } x}[/tex]

[tex]y = \mathrm{log_{0.5} x}[/tex]

[tex]y = \mathrm{log_1 x}[/tex]

[tex]y = \mathrm{log_{6} x}[/tex]

From the shape of the graph, in which, log x increases as x increases, therefore;

The base, b, of the logarithm is larger than 1, given that we have;

[tex]\mathbf{log_bx} = y[/tex]

[tex]\mathbf{b^y} = x[/tex]

From the given coordinate points, x increases as y increases, therefore;

b > 1

The possibly option is therefore, y = log₆x

Verifying, we have;

At x = -0.4, y = 0.5

[tex]b^y = x[/tex]

[tex]6 ^{(-0.4)}[/tex] ≈ 0.488

Therefore, the point (0.5, -0.4) is close to the graph of y = log₆x

At the point (1, 0), we have;

6⁰ = 1

Therefore, the point (1, 0), is on the graph of y = log₆x

At the point (6, 1), we have;

6¹ = 6

Therefore, the point (6, 1) is on the graph of y = log₆x

The function of the graph is therefore;

Answer: false

Step-by-step explanation:

Answer:

False because a sequence is geometric if common ratio of all terms of sequence is same.

here 8/6 is not equal 11/8.

Eg: the sequence 3,6,12,… is geometric because 6/3 = 12/6.

Answer: 31/36

Step-by-step explanation:Add them up..5/12+4/5 you need to convert to a common denominator. Common denominator is 36; 15/36+16/36=31/36

Answer:

[tex]\frac{31}{36}[/tex]

Step-by-step explanation:

To get the sum you have to have the same denominator.

So you have to find out what can 12 and 9 go into without leaving a remainder which is 36.

Then you divide 36 by 12= 3 and 36 by 9= 4

Then you multiply 3 by 5= 15 and 4 by 4= 16

You add then up and you get 31

So 31/36 is the answer.
