Suppose that the function f is defined. , for all real numbers, as follows.

aivan3 [116]

Answer: <em>The values of......</em>

Step-by-step explanation:

Given function is: $\left \{ {{f(x)= \frac{1}{4}x^2 -4, if x\neq -2} \atop {=-1, if x=-2}} \right.$

For $f(-5),$ the value of $x$ is -5, which is not equal to -2.

So, $f(-5)= \frac{1}{4}(-5)^2 -4 = \frac{1}{4}(25)-4 =\frac{25}{4}-4=\frac{25-16}{4}=\frac{9}{4}$

For $f(-2),$ the value of $x$ is -2.

So, $f(-2)= -1$

For $f(4),$ the value of $x$ is 4, which is not equal to -2.

So, $f(4)=\frac{1}{4}(4)^2 -4 =\frac{1}{4}(16)-4 =4-4=0$

We would like to estimate the proportion of UF students who owns a scooter to within 1% of the truth, with 95% confidence. We do

professor190 [17]

Answer:

Option A) 9604

Step-by-step explanation:

We are given the following in the question:

Confidence level = 95%

Standard error = 1%

$p = q = 0.5$

Formula for sample size:

$n = (z_{stat}\times \dfrac{p(1-p)}{\text{Standard error}})^2$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$n = (1.96\times \dfrac{0.5(1-0.5)}{0.01})^2 = 9604$

Thus, the sample size must be

Option A) 9604
