Answer:

The sample size is $n = 451$

Step-by-step explanation:

From the question we are told that

The margin of error is E = 0.03

The sample proportion is $\^ p = 0.12$

From the question we are told the confidence level is 95% , hence the level of significance is

$\alpha = (100 - 95 ) \%$

=> $\alpha = 0.05$

Generally from the normal distribution table the critical value of $\frac{\alpha }{2}$ is

$Z_{\frac{\alpha }{2} } = 1.96$

Generally the sample size is mathematically represented as

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

=> $n = [\frac{1.96}{0.03} ]^2 *0.12 (1 - 0.12 )$

=> $n = 451$

F(x)=4^x-8 g(x)= 5x+6 find (f-g)(x)

krek1111 [17]

F(x) = $4^x -8$

g(x) = 5x+6

(f – g)(x) = f (x) – g(x)

= $4^x -8 - 5x+6$
= $4^x - 5x-2$
