The value of the Euler \phi function (\phi is the Greek letter phi) at the positive integer n is defined to be the number of positive integers less than or equal to n that are relativel prime to n, For example for n=14, we have {1, 3, 5, 9, 11, 13} are the positive integers less than or equal to 14 which are relatively prime to 14. Thus \phi (14) = 6.Find the following:\phi(9) = __________.\phi(15) = __________.\phi(75) =__________.

Answers

Answer:

\bf \phi (9)=5

\bf \phi (15)=8

\bf \phi (75)=40

Step-by-step explanation:

Positive integers relative primes to 9 which are less or equal than 9

{1,2,4,5,7}

so

\bf \phi (9)=5

Positive integers relative primes to 15 which are less or equal than 15

{1,2,4,7,8,11,13,14}

and

\bf \phi (15)=8

Positive integers relative primes to 75 which are less or equal than 75

{1,2,4,7,8,11,13,14,16,17,19,22,23,26,28,29,31,32,34,37,38,41,43,44,46,47,49,52,53,56,58,59,61,62,64,67,68,71,73,74}

In a poll conducted by the Gallup organization in April 2013, 48% of a random sample of 1022 adults in the U.S. responded that they felt that economic growth is more important than protecting the environment. We can use this information to calculate a 95% confidence interval for the proportion of all U.S. adults in April 2013 who felt that economic growth is more important than protecting the environment. Make sure to include all steps.

Answers

Answer:

The  95% confidence interval is  0.449 < p < 0.48 + 0.511

Step-by-step explanation:

From the question we are told that  

     The sample proportion is \r p = 0.48

      The sample size is n = 1022

Given that the confidence level is 95%  then the level of significance is mathematically evaluated as

       \alpha = 100 - 95

       \alpha = 5 \%

       \alpha = 0.05

Next we obtain the critical value of  (\alpha )/(2) from the z-table , the value is

     Z_{(\alpha )/(2) } =Z_{(0.05 )/(2) }= 1.96

The reason we are obtaining critical value of    (\alpha )/(2) instead of    \alpha is because  

 \alpha represents the area under the normal curve where the confidence level interval (  1-\alpha ) did not cover which include both the left and right tail while    (\alpha )/(2) is just the area of one tail which what we required to calculate the margin of error

NOTE: We can also obtain the value using critical value calculator (math dot armstrong dot edu)

    Generally the margin of error is mathematically represented as

         E = Z_{(\alpha )/(2) } * \sqrt{(\r p (1- \r p ))/(n) }

substituting values

          E = 1.96* \sqrt{(0.48 (1- 0.48 ))/(1022) }

          E = 0.03063

The 95% confidence interval is mathematically represented as

      \r p - E < p < \r p + E

substituting values

       0.48 - 0.03063 < p < 0.48 + 0.03063

       0.449 < p < 0.48 + 0.511

B) 12%
C) 0.5%
D) 1.12

Answers

Answer:

Given below.

Explanation:

A) 0.02 = (2)/(100) =  (1)/(50)

B) 12% = (12)/(100) = (6)/(50) = (3)/(25)

C) 0.5% = (0.5)/(100) = (1)/(200)

D) 1.12 = (28)/(25)

Malik is buying a guinea pig. The guinea pig comes with a cage and food bowls for $ 125.00 . The expenses for feeding and caring for the guinea pig are $ 18.00 each month. How much will it cost Malik to buy and care for the guinea pig for one year?

Answers

Answer:

$341.00

Step-by-step explanation:

"$ 18.00 each month."

$18.00*$12.00=$216.00

$216.00+$125.00=$341.00
