How do i solve this?

Xelga [282]

Well this is considerably easy!

Create equivalent expressions in the equation that all have equal bases.

2^x=2^4

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

x=4

Verify each of the solutions by substituting them into 2^x=16

and solving.

x=4

Use the given data to find the minimum sample size required to estimate a population proportion or percentage. Margin of error:

lisabon 2012 [21]

Answer: 191

Step-by-step explanation:

Formula to find the minimum sample size required to estimate a population proportion or percentage:

$n= \hat{p}(1-\hat{p})(\dfrac{z^*}{E})^2$

, where $\hat{p}$ = proportion estimated by prior study.

E= Margin of error.

z* = Critical z-value.

Given : Confidence level = 95%

Critical value for 95% confidence = z*=1.96

$\hat{p}=\ 42\%=0.42$

E= 7%= 0.07

Then, $n= 0.42(1-0.42)(\dfrac{1.96}{0.07})^2$

$n= 0.42(0.58)(28)^2$

$n= 0.2436(784)=190.9824approx191$

Hence, the minimum sample size required=191
