Answer: 323

Step-by-step explanation:

The formula to calculate the sample size for proportion is given by :_

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

Given : Significance level : $\alpha: 1-0.95=0.095$

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

Margin of error : $E=0.05$

The proportion of successes : $p=0.70$

Now, the required sample size will be :-

$n=0.70(0.30)(\dfrac{(1.96)}{0.05})^2=322.6944\approx323$

Hence, the minimum required sample size = 323

1/2(4-+6x)=1/3x+2/3(x+9)

KonstantinChe [14]

Answer:

The value of x for the expression is 2

Step-by-step explanation:

Given algebraic expression as :

$\frac{1}{2}$ (4 + 6 x ) = $\frac{1}{3}$ x + $\frac{2}{3}$ ( x + 9 )

Now, solving the given expression

Or, $\frac{1}{2}$ × 4 + $\frac{1}{2}$ × 6 x = $\frac{1}{3}$ x + $\frac{2}{3}$ x + $\frac{2}{3}$ × 9

Or, $\frac{4}{2}$ + $\frac{6}{2}$ × x = $\frac{1}{3}$ x + $\frac{2}{3}$ x + $\frac{18}{3}$

or, 2 + 3 × x = $\frac{x}{3}$ + $\frac{2 x}{3}$ + 6

or, 2 + 3 × x = $\frac{2 x + x}{3}$ + 6

or, 2 + 3 × x = $\frac{3 x}{3}$ + 6

Or, 2 + 3 × x = x + 6

or, 3 x - x = 6 - 2

Or, 2 x = 4

∴ x = $\frac{4}{2}$

I.e x = 2

Hence The value of x for the expression is 2 Answer
