Y(x-1)=z divide both sides by y

x-1=z/y add 1 to both sides

x=(z/y)+1 or more neatly

x=(z+y)/y

How long (in years) would $900 have to be invested at 11.3%, compounded continuously, to earn $500 interest? (Round your answer

KatRina [158]

Answer:

6.13 years

Step-by-step explanation:

The computation of the number of years is shown below:

As we know that

Amount = Principal ×e^{rate,time period}

($900 + $500) = $700 × e^{11.3%, time period}

$1,400 = $700 × e^{11.3%, time period}

ln(2) = 0.113× time period

0.693147181 ÷ 11.3 = time period

= 6.13 years

Preliminary estimates suggest that about 58% of students at a state university favor implementing an honor code.

gtnhenbr [62]

Answer: c. 1498

Step-by-step explanation:

Given : Preliminary estimates suggest that about 58% of students at a state university favor implementing an honor code.

i.e. p = 0.58

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

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

Margin of error = $2.5\5=0.025$

The formula to find the sample size is given by :-

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\=(0.58)(1-0.58)(\dfrac{(1.96)}{0.025})^2\\\\=1497.302016\approx1498$

Hence, the minimum sample size needed = 1498
