Find the compound interest and final amount $950 for 2 years at 7½ per annum​
wlad13 [49]

Answer:

1092.50 account value

142.50 interest

Step-by-step explanation:

to solve compound interest questions we use the formula A=P(1+rt) where P is the principal (initial investment) r is the rate or the return (7.5%) and t is the interval or time so 2 years

now putting it together we get A=950(1+ (7.5x2)) = 1092.50 $

the interest is this value A minus the initial investmetn so 1092.50 - 950 = 142.50$

A survey of households in a small town showed that in 850 of 1,200 sampled households, at least one member attended a town meeti
Iteru [2.4K]

Answer:

Hence the confidence interval is ( 0.6745, 0.7422).

Step-by-step explanation:

Now the given are  

Sample size = n = 1200  

x = 850  

Sample proportion is  

\hat{p}=\frac{x}{n}=\frac{850}{1200}=0.7083  

We have to construct 99% confidence interval for the population proportion.  

Formula Used:  

(\hat{p}-E , \hat{p}+E)  

Here E is a margin of error.  

E =Zc\times\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}  

Zc = 2.58  

E =2.58\times\sqrt{\frac{0.7083*(1-0.7083)}{1200}}\\\\E=2.58\times\sqrt{0.000172}=0.0339  

So confidence interval is ( 0.7083 - 0.0339 , 0.7083 + 0.0339)

                                            = ( 0.6745 , 0.7422).
