Write the equation of the line on the graph

Answer:

36

Step-by-step explanation:

4(x+7) = 6(3x)

2(x+7) = 3(3x)

2x+14 = 9x

14 = 7x

x = 2

Plugging it back into the equation:

Hexagon = 6(3*2) = 6*6 = 36

Square = 4(2+7) = 4*9 = 36

Therefore, the perimeter of each figure is 36.

Answer:

a

The null hypothesis is  [tex]H_o : \mu  =  13.4000[/tex]

The alternative hypothesis is  [tex]H_a :  \mu \ne  13.4000[/tex]

The null hypothesis is rejected

b

The  99% confidence level is   [tex]13.3930  < \mu  < 13.3994 [/tex]

Step-by-step explanation:

From the question we are told that

  The sample size is  n =  10

   The  population mean is  [tex]\mu =  13.4 000 \  angstroms[/tex]

   The level of significance is  [tex]\alpha =  0.05[/tex]

   The  sample data is  

13.3987, 13.3957, 13.3902, 13.4015, 13.4001, 13.3918, 13.3965, 13.3925, 13.3946, and 13.4002

Generally the sample mean is mathematically represented as

        [tex]\= x =  \frac{13.3987+ 13.3957\cdots +13.4002 }{10}[/tex]

=>     [tex]\= x = 13.3962 [/tex]

Generally the sample standard deviation  is mathematically represented as

    [tex]\sigma = \sqrt{\frac{\sum (x_i - \= x)^2}{n} }[/tex]

=> [tex]\sigma = \sqrt{\frac{ (13.3987 - 13.3962)^2 +  (13.3987 - 13.3962)^2 + \cdots + (13.3987 -13.4002)^2  }{10} }[/tex]

=>  [tex]\sigma =0.0039 [/tex]

The null hypothesis is  [tex]H_o : \mu  =  13.4000[/tex]

The alternative hypothesis is  [tex]H_a :  \mu \ne  13.4000[/tex]

Generally the test statistics is mathematically represented as

      [tex]z  =  \frac{\= x - \mu}{\frac{\sigma}{\sqrt{n} } }[/tex]

=>    [tex]z  =  \frac{13.3962 -  13.4000}{\frac{0.0039}{\sqrt{10} } }[/tex]

=>   [tex]z =  3.08[/tex]

Generally the p-value is mathematically represented as

       [tex]p-value  = 2P( z   >  3.08)[/tex]

From the z-table  [tex]P(z >  3.08)= 0.001035[/tex]

So

       [tex]p-value  = 2* 0.001035[/tex]

      [tex]p-value  = 0.00207[/tex]

So from the obtained value we see that

     [tex]p-value  < \alpha[/tex]

Hence the null hypothesis is rejected

Consider the b question

Given that the confidence level is  99%  then the level of significance is

    [tex]\alpha =  (100 -99)\%[/tex]

=> [tex]\alpha =  0.01[/tex]

Generally from the normal distribution table critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

    [tex]Z_{\frac{\alpha }{2} } =  2.58[/tex]

Generally the margin of error is mathematically represented as  

     [tex]E =  Z_{\frac{\alpha }{2} } *  \frac{\sigma}{\sqrt{n} }[/tex]

=>   [tex]E = 2.58  *  \frac{0.0039}{\sqrt{10} }[/tex]

=>    [tex]E = 0.00318[/tex]

Generally the 99% confidence interval is mathematically represented as

     [tex]13.3962   - 0.00318  < \mu  < 13.3962   +  0.00318 [/tex]

=>   [tex]13.3930  < \mu  < 13.3994 [/tex]

5 1/2

Step-by-step explanation:

11/3 divided by 2/3= 5 1/2

Answer: either of two angles whose sum is 180°.

Step-by-step explanation:

Answer:

either of two angles whose sum is 180°

Step-by-step explanation:

a = 66 points (first test)

b = 98 (second test)

Hi there !

a = first test

b = second test

a + b = 164

b = a + 32

replace b

a + (a + 32) = 164

2a = 164 - 32

2a = 132

a = 132 ; 2

a = 66 points (first test)

b = 66 + 32

b = 98 (second test)

Good luck !

Answer:

Step-by-step explanation:

Answer:

1

Step-by-step explanation:

So when we raise a number to the zeroth power, that means we multiply the number by itself zero times - but that means we're not multiplying anything at all! ... In short, 0 is the only number such that for any number x, x + 0 = x

Answer:

Hi there! The answer to this question is 1.

Answer:

B) x = 6

Step-by-step explanation:

If you try substituting all the numbers (from these options) for x, you'll find that 6 is the only x value that can let the expression be further simplified.

[tex] \sqrt{39 \times 6} [/tex]

[tex] \sqrt{234} [/tex]

[tex] \sqrt{9 \times 26} [/tex]

[tex] \sqrt{9} \times \sqrt{26} [/tex]

[tex]3 \sqrt{26} [/tex]

Answer:

b and 59° are vertical angles so they are equal.

b=59°

[tex]3 {a}^{2} \times {b}^{2} \times 2ab + 6 {a}^{3} \times {b}^{2} = [/tex]

[tex]6 {a}^{3} {b}^{3} + 6 {a}^{3} {b}^{2} = [/tex]

Factoring 6a^3 b^2

[tex]6 {a}^{3} {b}^{2}(b + 1) [/tex]

American involvement in other countries.

Hope it helps ❤️

The labeled bolts of clothes represent the political cartoon will be about American involvement in other countries,

A drawing, chart, or graph that is labeled helps to visualize a concept. Students can better understand the relationships between the diagram's various components by using labeled diagrams in math, science, and language arts.

It is given that the labeled bolts of clothes represent the political cartoon.

They provide a cheerful diversion from the increasingly somber political discourse by offering a colorful alternative to formal news reporting. Cartoons offer a quick and easy way to comment on current events because they can condense news and opinion into a caricature.

Thus, the labeled bolts of clothes represent the political cartoon will be about American involvement in other countries,

Answer:

The decision rule is  

   Fail to reject the null hypothesis

The conclusion is  

   There is no sufficient evidence to accept  the manufacturing company claims

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  35

   The sample standard deviation is  [tex]s =  2.12[/tex]

   The level of significance is [tex]\alpha = 0.01[/tex]

The null hypothesis is  [tex]H_o  :  \sigma ^2  = 9.0[/tex]

The alternative hypothesis is  [tex]H_a  :  \sigma ^2  <  9.0[/tex]

Gnerally the test statistics is mathematically represented as

    [tex]X^2 _{stat} =  \frac{(n -1) * s^2 }{\sigma^2 }[/tex]

    [tex]X^2 _{stat} =  \frac{(35  -1) * 2.12^2 }{9 }[/tex]

=> [tex]X^2 _{stat} =  16.98[/tex]

Generally the degree of freedom is mathematically represented as

   [tex]df =  n - 1[/tex]

=>    [tex]df =  35 - 1[/tex]

=>    [tex]df =  34[/tex]

From the chi - distribution table the  critical value of [tex]\alpha[/tex] at a degree of freedom of  [tex]df =  34[/tex] is  

     [tex]X^2_{\alpha, 34 } =56.060[/tex]

From the value obtained we see that the test statistics does not lie within the region of rejection (1.e 56.060 , [tex]\infty [/tex]   )

Then

The decision rule is  

   Fail to reject the null hypothesis

The conclusion is  

   There is no sufficient evidence to accept  the manufacturing company claims

2.3r - 7 + 6 = 21

2.3r - 1 = 21

2.3r = 22
