Margin of error: 0.04; confidence level: 95%; from a prior study, bold p with bold overparenthesis on top is estimated by the de

GrogVix [38]

Answer: 235

Step-by-step explanation:

The formula to calculate the sample size :-

$n=(\hat{p}(1-\hat{p}))(\dfrac{z_{\alpha/2}}{E})^2$

Given : Estimated proportion $\hat{p}=0.89$

Margin of error : $E=0.04$

Significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2} =1.96$

Now, the required sample size will be :-

$n=(0.89(0.11))(\dfrac{(1.96)}{0.04})^2$

$\Rightarrow\ n= 235.057\approx235$

Hence, the required minimum sample size = 235

Determine the measure of ∠F.Question options:1) 64°2) 52°3) 128°4) 256°

OleMash [197]

ANSWER :

The answer is 1) 64

EXPLANATION :

The measurement of the inscribed angle is half the measurement of the intercepted arc.

From the given figure,

The inscribed angle is Angle F

The intercepted arc is Arc BD

So this will become :

$\begin{gathered} \angle F=\frac{1}{2}\text{Arc BD} \\ \angle F=\frac{1}{2}(128) \\ \angle F=64 \end{gathered}$
