Alinara [238K]

Answer:

Test statistic  z= 1.708

Step-by-step explanation:

given that a  television network is deciding whether or not to give its newest television show a spot during prime viewing time at night. If this is to happen, it will have to move one of its most viewed shows to another slot.

Sample size n = 827

Sample proportion p = \frac{438}{827} \\=0.5297

H_0: p =0.5\\H_a: p >0.5

(right tailed test)

This is because they would be interested if more than half viewers are ready for the change

Test statistic = Z = p difference/std error

p difference = 0.0297

Std error =\sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.5*0.5}{827} } \\=0.0174

Z =1.708

p valu e= 0.9562

Since p >0.05 we fail to reject H0

Test statistic  z= 1.708

Use the given information to find (a) sin(s+t), (b) tan(s+t), and (c) the quadrant of s+t. cos s = - 12/13 and sin t = 4/5, s an
Anton [14]

Answer:

Part a) sin(s + t) =-\frac{63}{65}    

Part b) tan(s + t) = -\frac{63}{16}

Part c) (s+t) lie on Quadrant IV

Step-by-step explanation:

[Part a) Find sin(s+t)

we know that

sin(s + t) = sin(s) cos(t) + sin(t)cos(s)

step 1

Find sin(s)

sin^{2}(s)+cos^{2}(s)=1

we have

cos(s)=-\frac{12}{13}

substitute

sin^{2}(s)+(-\frac{12}{13})^{2}=1

sin^{2}(s)+(\frac{144}{169})=1

sin^{2}(s)=1-(\frac{144}{169})

sin^{2}(s)=(\frac{25}{169})

sin(s)=\frac{5}{13} ---> is positive because s lie on II Quadrant

step 2

Find cos(t)

sin^{2}(t)+cos^{2}(t)=1

we have

sin(t)=\frac{4}{5}

substitute

(\frac{4}{5})^{2}+cos^{2}(t)=1

(\frac{16}{25})+cos^{2}(t)=1

cos^{2}(t)=1-(\frac{16}{25})

cos^{2}(t)=\frac{9}{25}

cos(t)=-\frac{3}{5} is negative because t lie on II Quadrant

step 3

Find sin(s+t)

sin(s + t) = sin(s) cos(t) + sin(t)cos(s)

we have

sin(s)=\frac{5}{13}

cos(t)=-\frac{3}{5}

sin(t)=\frac{4}{5}

cos(s)=-\frac{12}{13}

substitute the values

sin(s + t) = (\frac{5}{13})(-\frac{3}{5}) + (\frac{4}{5})(-\frac{12}{13})

sin(s + t) = -(\frac{15}{65}) -(\frac{48}{65})

sin(s + t) =-\frac{63}{65}

Part b) Find tan(s+t)

we know that

tex]tan(s + t) = (tan(s) + tan(t))/(1 - tan(s)tan(t))[/tex]

we have

sin(s)=\frac{5}{13}

cos(t)=-\frac{3}{5}

sin(t)=\frac{4}{5}

cos(s)=-\frac{12}{13}

step 1

Find tan(s)

tan(s)=sin(s)/cos(s)

substitute

tan(s)=(\frac{5}{13})/(-\frac{12}{13})=-\frac{5}{12}

step 2

Find tan(t)

tan(t)=sin(t)/cos(t)

substitute

tan(t)=(\frac{4}{5})/(-\frac{3}{5})=-\frac{4}{3}

step 3

Find tan(s+t)

tan(s + t) = (tan(s) + tan(t))/(1 - tan(s)tan(t))

substitute the values

tan(s + t) = (-\frac{5}{12} -\frac{4}{3})/(1 - (-\frac{5}{12})(-\frac{4}{3}))

tan(s + t) = (-\frac{21}{12})/(1 - \frac{20}{36})

tan(s + t) = (-\frac{21}{12})/(\frac{16}{36})

tan(s + t) = -\frac{63}{16}

Part c) Quadrant of s+t

we know that

sin(s + t) =negative  ----> (s+t) could be in III or IV quadrant

tan(s + t) =negative ----> (s+t) could be in III or IV quadrant

Find the value of cos(s+t)

cos(s+t) = cos(s) cos(t) -sin (s) sin(t)

we have

sin(s)=\frac{5}{13}

cos(t)=-\frac{3}{5}

sin(t)=\frac{4}{5}

cos(s)=-\frac{12}{13}

substitute

cos(s+t) = (-\frac{12}{13})(-\frac{3}{5})-(\frac{5}{13})(\frac{4}{5})

cos(s+t) = (\frac{36}{65})-(\frac{20}{65})

cos(s+t) =\frac{16}{65}

we have that

cos(s+t)=positive -----> (s+t) could be in I or IV quadrant

sin(s + t) =negative  ----> (s+t) could be in III or IV quadrant

tan(s + t) =negative ----> (s+t) could be in III or IV quadrant

therefore

(s+t) lie on Quadrant IV

After 100 spins, Lincoln calculated the probability that he would spin a prime number to be 0.35. Using the
quester [9]

Given:

Total number of spins = 100

Probability that he would spin a prime number to be 0.35.

To find:

The theoretical probability of spinning a prime number.

Solution:

Total numbers from 1 to 100 = 100

Total prime numbers from 1 to 100 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

So, the prime numbers from 1 to 100 = 25

Now, the probability of spinning a prime number is

\text{probability}=\dfrac{\text{Total prime numbers from 1 to 100}}{\text{Total numbers from 1 to 100}}

\text{probability}=\dfrac{25}{100}

\text{probability}=0.25

Therefore, the theoretical probability of spinning a prime number is 0.25.
