What is Division?

The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication. In simple words, division can be defined as the splitting of a large group into smaller groups such that every group will have an equal number of items.

Given:

We have to divide 12.645 by 8.43

So,   12.645/8.43

= 12645/ 8430

=           8430 | 12645   | 1 . 5

                         8430

                      -______

                          42150

                          42150

Hence, the quotient is 1.5.

Step-by-step explanation:

We are given:

If  [tex]i=\sqrt{-1}[/tex] we need to find the value of [tex]i^3[/tex]

Solving:

[tex]i=\sqrt{-1}[/tex]

Taking cube on both sides

[tex]i^3=(\sqrt{-1})^3\\[/tex]

We can write [tex]a^3= a^2.a^1[/tex] Using this for solving:

[tex]i^3=(\sqrt{-1})^2.(\sqrt{-1})\\We \ know \ (\sqrt{-1})^2 =- 1 \ and \ \sqrt{-1}=1 \\i^3=-1(i)\\i^3=-i[/tex]

3. 40 adult tickets and 160 children's tickets
4. 30 adult tickets and 120 children's tickets

Answers

Answer:

B

Step-by-step explanation:

multiple 12 and 120 which is 1,440 then multiply 4 and 30 which is 120 and add it up which comes to 1,560. HOPE THIS HELP!!!

The total number of adults tickets sold and children tickets sold is 120 adult tickets and 30 children's tickets

Given:

Cost of adult tickets = $12

Cost of children tickets = $4

let

number of children tickets sold = x

number of adult tickets = 4x

Total cost of tickets = 1560

The equation:

1560 = 12(4x) + 4(x)

1560 = 48x + 4x

1560 = 52x

divide both sides by 52

x= 1560/52

x = 30

Therefore,

number of children tickets sold = x

= 30 tickets

number of adult tickets = 4x

= 4(30)

= 120 tickets

Assuming normality, construct the requested confidence interval.

A sociologist is interested in the age at which a mother has her first child. A random sample of 20 recent births yielded an average maternal age to be 30 years with a standard deviation of 6.2 years.

Construct a 99% confidence interval for the mean age at which a mother has her first child.

Can I have some help with solving this problem with a TI84 calculator?

Answers

Answer:

The appropriate response is "(26.03, 33.97)".

Step-by-step explanation:

The given values are:

Average maternal age,

[tex]\bar{x} = 30[/tex]

Standard deviation,

s = 6.2

Random sample,

n = 20

Now,

The degree of freedom will be:

⇒ [tex]df=n-1[/tex]

        [tex]=20-1[/tex]

        [tex]=19[/tex]

"t" at confidence level 99%, will be:

⇒ [tex]\alpha=1-99 \ percent[/tex]

       [tex]=1-0.99[/tex]

       [tex]=0.01[/tex]

⇒ [tex]\frac{\alpha}{2}=\frac{0.01}{2}[/tex]

       [tex]=0.005[/tex]

⇒ [tex]t\frac{\alpha}{2} \ df=t \ 0.005,19[/tex]

By using the student table, we get

             [tex]=2.86 1[/tex]

The margin of error will be:

⇒ [tex]E=\frac{t \alpha}{2,df\times (\frac{s}{\sqrt{n}})}[/tex]

On substituting the estimated values, we get

⇒     [tex]=2.861\times (\frac{6.2}{\sqrt{20}})[/tex]

⇒     [tex]=3.97[/tex]

At 99%, the confidence level will be:

⇒ [tex]\bar{x}-E< \mu <\bar{x}+E[/tex]

⇒ [tex]30-3.97< \mu < 30+3.97[/tex]

⇒ [tex](26.03,33.97)[/tex]

Thus the above is the correct approach.

Complete Question

How large a sample is needed if we wish to be 96% confident that our sample proportion in Exercise 9.53 will be within 0.02 of the true fraction of the voting population?

Exercise 9.53

A. A random sample of 200 voters in a town is selected, and 114 are found to support an annexation suit. Find the 96% confidence interval for the fraction of the voting population favoring the suit.

B. What can we assert with 96% confidence about the possible size of our error if we estimate the fraction of voters favoring the annexation suit to be 0.57?

Answer:

The First question

                    [tex] n = 1879  [/tex]

A

    The 96% confidence interval is  

                      [tex]0.51 <  p <  0.63 [/tex]

B

   The possible size of our error if we estimate the fraction of voters favoring the annexation suit to be 0.57 is  

           [tex]E =    0.06 [/tex]

Step-by-step explanation:

From the question we are told that

    The margin of error is  [tex]E = 0.02[/tex]

     The sample size is  n =  200

     The number that supported the annexation suit is  k = 114

Considering the first question

Generally our sample in Exercise 9.53 is  [tex]\^ p = 0.57[/tex]

From the question we are told the confidence level is  96% , hence the level of significance is    

      [tex]\alpha = (100 - 96 ) \%[/tex]

=>   [tex]\alpha = 0.04[/tex]

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

   [tex]Z_{\frac{\alpha }{2} } =  1.751 [/tex]

Generally the sample size is mathematically represented as  

    [tex]n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) [/tex]

=>  [tex]n = [\frac{1.751}{0.02 } ]^2 * \^ p (1 - \^ p ) [/tex]

=>  [tex]n = [\frac{1.751}{0.02 } ]^2 * 0.57  (1 -0.57  ) [/tex]

=>  [tex] n = 1879  [/tex]

Considering question B

Generally the margin of error is mathematically represented as  

     [tex]E =  Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]

=>  [tex]E =    1.751 * \sqrt{\frac{ 0.57  (1- 0.57 )}{200} } [/tex]

=>  [tex]E =    0.06 [/tex]

Considering question A

Generally the sample proportion of the number that supported the annexation suit is mathematically represented as

        [tex]\^ p = \frac{114}{200}[/tex]

=>      [tex]\^ p = 0.57[/tex]

Generally 96% confidence interval is mathematically represented as  

      [tex]\^ p -E <  p <  \^ p +E[/tex]

=>  [tex]0.57  - 0.06 <  p <  0.57  + 0.06 [/tex]

=>  [tex]0.51 <  p <  0.63 [/tex]
